    Why no tire pressure monitors on the RX400h? As tire pressure is important to fuel economy it seems a bit weird not to have 'em on a hybrid. Besides I thought they were required by law after 2005.
    One other question...the new RX400h brochure noted that XM radio would be available in February. Can that be added by the dealer to a vehicle purchased earlier?

    Thanks!

    For the last couple of weeks I've noticed what I would call "wind noise" when I'm driving around. It's especially loud out on the highway; much more than I would anticipate from the normally cushy, quiet Lexus. It sounded like maybe a window was cracked open but I checked them all plus the sunroof several times. I took the car to the dealer a couple of days ago and when we took a test drive, the diagnostics specialist said it sounded like "we were driving in a cross wind". When we got back to the shop he checked a couple of things and they are still working on it. One thing he pointed out was that the front tires were wearing unevenly while the rear tires were pretty good. He said that's not unusal in this car but I just had it in for the full 10K service a couple of months ago so at best the tires have 12K on them. He said the tires could be causing some of the noise. Has anyone else experienced either of these problems? Could they be related?

    The tires could be causing the noise. I've experienced this after rotating unevenly worn tires from the back to the front on other cars. If you do a Google search for tire roar, you will find many complaints of uneven tire wear on the front tires of 350Zs causing tire roar. If you do a Google search for tire noise, you will find info on that neglecting tire rotation on FWD vehicles can cause uneven wear and tire noise or humming. Cross switching the front tires to the rear may lessen your tire noise.

    I am just curious what other peoples tires and pressure are on their 400h.

    Michelan 235/55R18 99V @ 38 PSI is what mine is at. After driving it home from the dealership I found the front tires at 37 and the back tires at 38 so I just inflated the front tires to match. I noticed that the recommended PSI on the door is 30 and that the max PSI on the wall of the tire is 44.

    I am looking to squeak out as much MPG as I can but do not want to overinflate the tires.
  • Lexus ships the 400h from Japan with high pressure to avoid flat spots on the tire. The dealer is supposed to reduce the pressure to between 32 and 34 at delivery. Mine came with the pressure at 44. I called the dealer, and they are the one's who recommended 32 to 34.
  • Does the 2006 model not hv the tire pressure monitor system?
    The 2007 does and frankly, after reading it, maybe wishes I didn't have it.

    Something about after changing to new tires and take it back to Lexus for hook up (?) which probably means $$ out of my pocket.

    Can someone shed some light to this?
  • 2006 400h did not come with tire pressure monitor. Not sure why it didn't since all other 2006 Lexus models did come with it.
  • We have taken our vehicle as specified by manufacture recommendations and at 10,000 miles the tires were rotated. Since then there has been a terrible shimmy and vibration up thru the steering wheel. It is not constant but enough to be very irritating. We have told the service people immediately about this and on subsquent maintence visits we hear the same line "you need new tires". How is it that this started immediately after the tires were rotated at 10K service?
    Now we are at 30,000 miles maintence. The shimming and vibration is even worse now than it has been ever. Guess what the lexus service is saying - ..."you need new tires." How is it this is ONLY a tire problem and not an alignment or steering problem since it has been going on since 10,000 miles on vehicle?How is it a $51,000 car has tires which only last for 10,000 miles.

    I've always done rotations between 5000 and 6000 miles. Any longer than that and you can start to get unsual wear. And when you rotate worn tires, you CAN suddenly get unusal vibrations andnoises with the worn tires in a new location.

    Just did a little follow up with a friend of mine who owns and operates and independent tire shop/garage. Not only is 10,000 miles far too long between rotations, he also tells me Lexus' tend to eat tires in his experience, AND Lexus puts "performance" tires on their vehicles which are going to have a practical lifetime of 25-30,000 miles.

    So I think what got your attention was something that makes sense. Go too long without rotating tires and the wear on tires causes unusual sounds and sensations when they get moved to different wheel locations.

    My gut is telling me that tires will eliminate your shimmy and vibration. Your tire choice is probably going to have to be a tradeoff involving performance, ride comfort/noise, and expected tread life.

    I'll try to stop in and see my buddy tomorrow and see what kind of options he'd advise for replacement tires!

    Have a RX 400h with 26K. I have 50/50 mix of driving around town and highway usage. Have car always serviced at dealer at recommended intervals. Only isuue during this period was a small mention on the @ 10K service report suggesting front end alignment might be needed at next service. Ask about this and they said wait for next tire rotation at 5 K and the tires should even out. Nothing mentioned at the 15K service. Then at 20K service when I mention an annoying and worsening tire noise at 50+ MPH they then tell me the tires are wearing unevenly and I will need new tires soon. I compained and they were supposed to follow-up with tech dept and call me back. I didn't hear from them and got busy myself and didn't call to pester. (bad me) Yesterday at 25K service it's official, I need new tires and the dealer says 25-30K is all that can be expected on tires for this model. Can anyone tell me why the RX 400 gets such short tire life? Also they say I need front end alignment and this is always done with new tires - this is news to me.

    I bought an '07 400h in May of last year. It had Goodyear tires. I rotated the tires every 5,000 miles. At around 15,000 miles, the tires started making excessive noise. I first took it to an independent shop where I normally get the oil changed and tires rotated. They said that the tires were "cupping" on the inside and would only get worse. I took it to the local Lexus dealer (not where I bought it) and after proof that I had rotated the tires at proper intervals, agreed to provide 2 free tires (Michelins) if I bought 2 and had it aligned. I agreed. Problem solved. I suspect that the vehicle had been out of alignment from the beginning. The "code" on my invoice indicated that the tire replacement was "goodwill". A lesson learned is that even with the purchase of a new car, it is probably wise to get an alignment right away. I ordinarily get 50 to 60 thousand miles on tires because I keep them inflated to 35 psi and have a rotation every 5,000 miles.

    I am curious as to what dealer and city did you deal with AS this is exactly the same story that was told to me and I documented having vibration felt through steering wheel starting a few weeks after I got the car (LS 460). It had Bridgestone's.

    I rotated every 5,ooo per their suggestion and even rebalanced at 10,000 miles to no avail. Now, I have to buy 2 at their dealership and they will pay for the other 2.

    They indicated that I must buy 2 or they will not buy the other 2.

    I called Michelin (this is what I am putting on as replacement) and they said to first cure the problem before putting new tires on or the same problem will reoccur.

    The dealer can't find the problem. He said that it tracks perfectly straight and when putting on brakes, it doesn't pull to one side. they have concluded that they can't explain why it is cupping!!1 Won't this just reoccur again soon after putting on 4 new tires ?

    Any help will be appreciated. Please send response to my personal e-mail address which is: kr5flute@yahoo.com Thanks. RD

  • The dealer is in Naperville Illinois. I finally caved after a little more research with tire dealers. One interesting story I was told was that during shipment the cars can be strapped down so tightly that the wheels bow outward. Haven’t a clue if anything I was told was accurate. I split the fee for 4 new tires and an alignment. Went for the Michlin brand tire. My car is now better than brand new in terms of a smooth ride. I even increased gas efficiency! However, I will not be taking my Lexus back to the dealer for any routine service and will be documenting all service and problems to CYA just in case of future issues with this or anything else.

    Good Luck!

    after service at 30.000km the dealer say i needed now tires in the front.oke i did so.
    but now i have an vibration at 130-150 km speed.Sorry i dont know the miles, i live in HOLLAND, and sorry my bad English. The dealer does every thing but cant fixed it. my tires are bad on the inside. I also have new tires now at the back.The vibration still resist. i am sure the cannot solve my problem!!
  • I own a 2007 RX400h with 38,000 miles on it. I am on my third set of tires. At my first oil change I was warned by the dealership that I would only get about 12,000 miles out of the tires if I was lucky. I called the sales person I purchased the car from and asked the same question you did. How can a $50,000 car have such cheap tires on it? I was told the service person was wrong and my tires would last for at least 30,000 miles. That was a lie. I bought my second set at 18,000 miles, as the first ones were bald. Just put on the third set at 38,000 miles, guess I should be grateful I got 20,000 out of set #2! Both sets #2 and #3 are Michelin tires ($1200 for 4). I am selling this car as I cannot afford to put tires on it every year. The only plausible explanation is that my driving conditions include about 5 miles of curvy road daily, the rest of my commute is highway. I believe this must be a design flaw, as every other car I have owned did not have this problem.
  • We purchased a Lexus RX400h new in 2006 and are now going on our THIRD set of high quality/high performance tires.
    The tire wear is very excessive having to replace them in about 1/3 of estimated mileage..
    The car has its oil changed, tires rotated, checked for alignment every 3,000-5,000 miles. It appears to drive fine with no pulling, etc. The tires even seem to wear evenly, just FAST!
    The original set of 60,000 mile rated tires that came with the car literally shredded (you could see the steel belts) at 20,0000 miles.
    Judging from some of the comments in this Edmunds forum and others, Lexus seems to have an issue. Why so much excessive tire wear relative to miles travelled?
  • I have a 2007 RX 400h with factory installed Michelins with over 15,000 miles and no discernable wear. I keep 35 pounds of air in them and rotate every 3,000 miles. Alignment is done annually.
  • about my tires. The garage had a machine that did not function well.The machine that balance the tires did work wrong. That causes my tremble in the car. Now i have yoko hama tires en everythings is good.Simple simple.

    I am considering purchasing a used RX400h and when I check the Carfax sheets I am seeing that a number of these vehicles have had 4-wheel alignments in the first
    10-15K miles. Is this normal or a sign of poor alignment/tire problems? I am currently looking at this as a red flag for each vehicle....should I be?
  • After going through 3 sets of tires that wore out pre-maturely, I received a recall notice from Lexus regarding the electric steering box and the need to have it replaced. I took care of this recall promptly. Next I bought a new set of Michelin tires at Costco. I asked the Costco service manager to recommend a wheel alignment specialist. He did, and I had the car serviced by him. His equipment for aligning is the old fashioned kind, not a computer. The tires have 13000 miles on them and they look as good as the day I purchased them. There is no wear on the inside of any tire.
    Here is the questions; 1. Did the new steering box cause this positive result? If so, how come Lexus never admitted to the premature tire wear was their fault and why did it take them 3 years to finally change the mechanism? or
    2. Did the guy who did the alignment really do the first real good alignment on this car? Did this alignment result in the positive results?

    Not too clear! But I still see many posts about premature tire wear on the Lexus 400H

    Brakes--momentary "surge". "Regenerative Braking." ???

    Battery. On life support because it is always dying. Had to buy a -"trickle charger."

    First told I needed new tires at 15,000 miles. Took car in at 20,000 miles and was told the tires were fine. Parked with tires at an angle and my brothers told me my tires were ALL bald on the inside--that they must be out of alignment and I should not be driving the car with bald tires. Also told that tires must be leaning in to cause that "cupping." Service manager said that the Lexus 400H (2006) never needed alignment. I find that hard to believe. Taking car i tomorrow for new tires etc.

    Does this sound like a $50,000 plus car with 21,585 miles on it? I am thinking of pulling its feeding tube.

    msj09 - i wondered if you did buy a 400H? Mine is a 2008 & at 20,000 miles the tires went down to the metal strips on the insides. A technician put new tires on & aligned them. He said after he aligned it that the alignment was good & should not have caused the premature tire wear & cupping on the insides . This seems to be a Lexus problem & not the tire mfg. I wonder if the weight of the hybrid battery has not been properly considered in the design & if the next set wears out quickly - that will confirm a Lexus problem for which I hope they will compensate. How many other people have this problem? Do we need to get legal representation? Jsea
  • I too had tire problems at 25000 miles, and this is after 4 years of babying this car. Look, this is a Lexus issue, that they won't take responsibility for, due to the exorbitant overall cost to them. I've been told by my service ppl, whom I trust, that this is a tire problem caused by excessive weight from the hybrid system which is unevenly distributed across the car, putting stress on the inside of the tires. Sounds reasonable enough to me. So, the "alignment" issue that one would normally expect from this kind of wear, really isn't the issue, and I doubt they can "overcorrect" the alignment to account for this. Hence, it will be a permanent problem with this vehicle IMHO. So, first I'd tel you to plan on buying tires about every 20,000 miles, which is ridiculous but unavoidable. It will take serious class action litigation to get Lexus attention, and these usually don't result in much change to consumers, it's the lawyers who get the money. I am VERY disappointed in this experience, and with the way Lexus is handling it....but maybe less surprised after seeing how Toyota the parent company, mishandled al of those recalls the past year. Lexus really blew a TON of consumer loyalty on this debacle.

    I propose a realistic compromise to Lexus----charge the owner only $400 flat to replace the tires every 20000 miles, using the highest quality rated michelin tires, including balancing, alignment check, etc, for the remaining life of these cars. It's a cost I wasn't expecting and not thrilled about, but this is a high-price, high performance car, and I'd reasonably assume this cost as part of unforeseen "maintenance" for the 400h, if only Lexus would come clean on their end, and provide a reasonable "settlement" of this issue for everyone. If they did so, it would restore confidence in the brand, and as try could also plan on this as a maintenance item, they could negotiate cheaper pricing on the tires and still make a little money on the deal. For our part, at least we'd know we'd be getting new, high quality tires every 20k, at closer to cost, and any Lexus 400h owner should be able to afford this.

    HOW ABOUT IT LEXUS.??
  • I have a Lexus 400H and had 4 new tires at approx 50,000 and was just told I need 4 more at 73,000. My service manager told me that I should expect to get 20,000 miles on the new tires. I just called Firestone and they warranty their Lexus 17" & 18" tires for 65,000 miles. Something does not add up here. We need to figure out what the heck is going on as I definitely think we should be getting more than 20,000 miles on new tires.
  • My tires looked OK from the outside & had plenty of tread left, but when they took them off the metal strips were showing & there was severe cupping. on the inside edge. I couldn't believe the deterioration at only 18,000 miles. I waited til 20,000 to take it in to Pep Boys & could have had a tire blow. I only took it in because of the noise, never saw the wear. Lexus needs to own up to this defect & reimburse people or they could be in for a class action suit from some hungry attorney. I'm really mad.

    When some lawyer decides there is money to be made with the Lexus rx 400h tire wear issue, have hime contact me on this forum. I cannot in my right mind buy another lexus rx450h until this problem of tire wear is solved.

    Is this by chance restricted to the F/awd versions of the RXh and HH..??

    It is my understanding that these vehicles automatically apportion drive torque to the rear in a pre-emptive manner during low speed acceleration and turning.

    In a more "standard" AWD or 4WD when the opposite drive is engaged the entire driveline and the tires are subjected to the stress and heat from driveline windup and/or tires scrubbing.

    With the RXh and HH only the tire scrubbing is present when the opposite drive axles are engaged. That might well result in premature tread wear.

    Go to the Highlander hybrid thread and search "tire wear".
  • I'm at 17k miles & need to replace my tires. Grrrrrr. :mad:

    I have 34K on 400H AWD. Original Good Year. The lexus dealer said needs replace soon, however Ok to drive 5000 ml more.
    I also have 2008 lexus LX 570 - Michelin lattitude HP tires - 35000 miles on those. Dealer said I have to replace soon.
    My Toyota Sienna 2002 had 65000 miles with firestone tires when I replaced them.
    I can confirm : original tires from the factory run around 30K in average!
    The tires from the stores are better for some reason and last longer!
