Infiniti M35/M45 Tires

    06 M35 Would like new tires. Have 44k on RS-A. Want something with less road noise and fun to drive. What is the answer?

    Michelin Primacy MXV4, I have 15k miles on them and they are great in all kinds of weather. I live in the upper mid-west and drive through a lot of snow and rain. Quiet, no flat spots, handle great in all types of weather and on all surfaces. $1100 at the Infiniti dealer, including alignment and 2 year road hazard warranty. I could have saved a $100 bucks at the tire store but I wasnt comfortable with their ability to deal with any TPMS problems that might occur, even the dealer had a problem with one wheel.

    Good luck. Mine is a 2006 M35X.

    For anyone who cares, I have now had General Exclaim UHP tires of my M35 for 7 months and 9k miles. Wear and tear is minimal, handling in wet/dry is great and ride is very nice. For anyone looking for an amazing bargain, look no further. They are also the highest rated performance tires on Tire Rack.

    The dealer installed the Yokohama tires and I'm shocked at the difference they have made!! :D The ride is silky smooth and the noise is dramatically reduced. I'm not sure how the tires will perform in rain or snow, but I'll update once I've driven in those conditions. I am so happy that this worked out.

    Hello all,

    I was hoping someone could help me out with which way I should proceed. I recently bought a Certified 07 M35x that came off of a 2yr lease. I've had the car for about a week now. I just noticed that there are two different pairs of tires on the car. The two front wheels have the Goodyear RS-A's on them and the back two wheels have Hankook Ventus V4's on them. They're all 245-45-18 though. All four tires have fairly good tread left on them.

    Do I have any ground to ask the dealer to give me a complete matching set or offer some type of discount for a new set? Or am I screwed for not noticing the difference before I bought the car.
    If the dealer won't do anything about the tire brand difference should I keep them. The ride isn't the greatest as far as road noise and vibration. I'm comparing this to the ride of the G35x that they gave me while my car was being serviced.

    Thanks for the advice!

    Read the owner's manual...I'm pretty sure that it states ALL tires must be the same brand and type. This is more important on the all-wheel drive versions than rear-wheel only, but can be a safety issue on either as it will alter the front/rear grip and braking. Also, there is a spec about the real's pretty tight, I think like 1/8", and you may not have that with different brands, or even different models from the same company. That's why on all-wheel drive cars, it becomes expensive, as you often need to replace all four tires when you have a problem with one.
  • If you bought this car from an Infiniti dealer and if it is certified then definitely go back and get four of the same tires. ABS systems can be dangerous if you don't have the same tires on all four wheels.

    Push the dealer to give you four of the same tires.......a certified car should meet the manufacturers requirements as stated in the owners manual....

    If they won't do it, escalate to Infiniti. Tell them that they are liable if there is any problem/accident caused by tires that don't match. Someone will give....

    Thanks! I just looked at the manual and you're right. I will use this info when I talk to the dealer.
  • Hi Chris. Sounds like the Leasee or dealer replaced 2 of the original Goodyear tires. You could ask the dealer about matching them somehow but they may reply you missed it before buying. At least they are the same size. You could check with a discount tire dealer about getting a new set of 4 with some money off for your current tires. I got 4 Contiprocontacts installed for under $600 and really like them. Now there is a General all season tire rated best in category (245-45-18) and probably well priced. Check with a mechanic you trust. Good luck.
  • you missed "certified" used car. I don't think the dealer has a leg to stand on...he fundamentally sold a car that does not meet the manufacturers requirements.

    While you have to be pleasant, I think that being firm will get a set of matching tires. You might even be able to sneak it in under the used car warranty and get the tires replaced. They could just swap them with another used car on the lot.

    If not, I would personally buy two new matching tires and take the dealer to small claims court. It will not play well when you show 1) the car was a "certified" used car; 2) It was purchased from an Infiniti dealer; 3) the owners manual says that the tires must be the same; 4) the car has mismatched tires. The dealer will hide behind the fact that certified doesn't address anything other than tire depth...but I suspect I would win based on the sheer simplicity of the logic.

    Now if there was an accident where the tires came into play, the lawyers would just have a field day with this one....

    I need to replace the RSAs on my M35x. I've seen many advertised replacement tires (ContiExtremeContact, Michelin Primacy, Potenza RE960, Yokahama Advan S.$ and Avid W4S, Eagle GT's and on and on). I won't put RSAs back on the car, but would like to get opinions from others who've put different tires on your M35 and what you like/dislike. I am in the midwest, so I'm in wet, dry and a little snow, and drive the highway at higher speeds 50% of the time.

    2006 M35x. Last winter I replaced the RSA's with Conti Contacts. The car rides much better. Traction in snow and rain is more confident. The steering is not as precise as the RSA's. My decision was based more upon price. My 3-year lease expires in January. I drive in suburban NY City mostly. I rarely exceed 70 m.p.h. I have gone to VT and been satisfied in the snow. If I owned the car I may have bought more expensive Michelins. If I skied allot I would buy winter tires.
  • The ContiExtremeContacts have been great on my M35X for 12k miles. Much better than OEM Goodyears. Best part, tires installed were under $600 in NH.
  • Has anyone tried 245/45x19 tires instead of the 245/40x19 tires that come as original equipment on a M35 sport?
  • james27james27 Posts: 433
    The higher profile tile would be close to 1" larger in diameter, and throw the speedo off by about 1%. If you have the nav system, it should autocalibrate. That extra inch may mean the tire will rub when turning or if you hit a large bump. This could poke a hole in the tire.
  • This Place

    Has 4 ContiExtremeContact for under $500 and cheap shipping does anyone know if this is a good deal and if these are as good as the original tires?
  • barryendbarryend Posts: 121
    I have them on my 2006 M35X. Much better ride & traction in the wet. Sounds cheap. Add in freight, tax, mounting and balancing. Go to local tire store and show them the on-line price and see what deal they will cut. Make sure you don't lose the wheel lock key like I did.
  • I am considering getting an M35 RWD and I wonder how bad it will be to drive it in Michigan winter?
    Anyone care to share their experience driving M35 RWD in semi-harsh winter conditions (Midwest, not Alaska) ?
    Do winter tires make it better to the point of being managable?
    TIA !

    I have driven both a miata and a BMW 3 series during snowy winters commuting about 30 min each way in Connecticut. Both cars are reputed to be poor in the snow and ice. I never had a problem....but the key is to put four good snow tires on the car...not 2, not studded, not heavily worn and built to grip in the snow/ice with soft rubber. At the time I used Blizzaks. Of course you have to be careful not to spin the wheels and keep your speed even.

    Of course 4wd cars are better in the snow......however, I have also driven Jeep Cherokees and Grand Cherokees to/from Vt and it's the only car that I lost control in on an fact there were a few days with black ice that many jeeps spun out...I was far from alone. Nothing helps in black ice...and actually a 4wd car is more likely to spin out because you are over confident. In heavy snow, a Jeep is just wonderful....

    My view is that 4 good new winter tires make any car manageable in the snow.

    All-season tires are a compromise all seasons. Good snow tires can make a huge difference in traction not only when the roads are nasty but anytime the temperature drops below 40-degrees F. All-wheel drive can help you get started and maybe grab some traction in a turn, but nothing beats the laws of gravity. Stopping would be the same, regardless of the number of driven wheels (with the exception that the 4-wheel version is a little heavier).

    Apparantly on the 2009, the M35 gets the new transmission and engine; the M35x gets the engine, but keeps the old 5-speed.
  • I have an 06 M45 and just placed a set of Bridgestone Turanzas and I have been pleased. I have a sport and they softened and quieted the ride. The also handle decent and are pretty good in the rain. They also seem to have solved a steering problem that me and other sport owners were having. They don't make them in the OEM size so you have to go up one which the dealer opposes. Tires are great and the only drawback is the price. $1400 for the set!!!!!
  • So I just got an 08 m35x, I've never owned a car with size 45, goodyear. the ride seems rough and sensitive to road conditions. Can the car handle thicker tires? like 50 and above? would this help to give a more comfortable ride?
  • tsoltsol Posts: 40
    Yeah, I've had both an early '06 and late '07 M35x both with stock Goodyear RS-As and find it aggravating that my wife's FX is much more stable on-center.

    Supposedly there was a steering rack replacement fix for the '06, but my '07, now, after 15k miles is as bad as my '06 was. Hope someone figures it out someday ... tires or suspension???
  • I have an Infiniti 2006 M35X. I live in Chicago and most of my driving is on the highway.

    Its time for new tires.....and it was suggested to me to get either the

    Yokohama YK520 tires
    Eagle F1 - All Season

    Can anyone render an opinion or suggest an alternative

  • I have a 2006 M35x as well and replaced my original tires with Eagle F-1's. I've been very please with the handling and traction. After about 10,000 miles, I am a little annoyed with the road noise they create. They are sporty tires and the ride is good, so all in all I am very pleased with the F-1's. Surprisingly, they were less expensive than the RS-A's that were original to the car.

    2006 M35X, replaced the RSAs with Michelin Primacy MXV4, I have 25k miles on them and they are great in all kinds of weather. I live in the upper mid-west and drive through a lot of snow and rain. Quiet, no flat spots, handle great in all types of weather and on all surfaces. $1100 at the Infiniti dealer, including alignment and 2 year road hazard warranty. I could have saved a $100 bucks at the tire store but I wasnt comfortable with their ability to deal with any TPMS problems that might occur, even the dealer had a problem with one wheel. Also still have 9/32 of tread depth after 25K miles, the RSAs were almost bald ! I do rotate every 7500 miles.
  • c5_4func5_4fun Posts: 59
    I put the Michelin Primacy MXV4's on my M35x a few weeks ago. I live in the Midwest and have already had the opportunity to experience driving in a variety of climates/road conditions. Thus far, they've been great in all weather: rain, sleet, snow (3-4 inches) and dry at highway speeds. You can check out websites for Tirerack and Discount Tires as a few places to compare and contrast the tires as well as get comments from the users. Right now, both Costco and Sams had discounts on Michelins which brought them down closer to the price of the next few competitors, and these tires have a 60K mile warranty (for whatever that's worth!). Beware as I got one surprise: TPMS "rebuild" charge of $10/tire.

    "Also still have 9/32 of tread depth after 25K miles"

    That is not possible, as the tread is 11/32 when new, if it only goes down 2/32 for 25K and assume it need to be replace at 2/32, the tire will last you 25k/2*7 = 87.5k. I don't think there is such high performance tire exist yet. It would be more reasonable (consider the rating of the tire) to have 7/32 left.
  • bobicgbobicg Posts: 15
    I hate to inform you shmang that this is a tire with a 60K warranty and with regular rotation, proper air pressure, regular alignment and the majority of miles being highway 80k miles can easily be achieved. I have gotten over 100k miles on a set of Michelin LTX's on my wife's Lexus SUV using the same rotation scheme. Most people never pay attention to alignment, air pressure and rotation so their wear rates are accelerated. The 9/32 number is correct. Any other tire "experts" out there want to weight in on this subject?
  • shmangshmang Posts: 297
    I knew this tire has a 60K mile rating and proper maintenance will help. But, I was also assuming that part of the reason anyone get the M is to have fun and doing at least some spirited driving. So, to get close to 90k is almost impossible. On the other hand, I can see that happen on a Lexus (You don't buy a Lexus for hot-rod).

    I do not consider myself an expert on tires, but I am very knowledgeable. Unless you drive the M like you drive a Civic, you are not going to get 87k out of 1 set of tire for sure. But, you might drive conservatively, which was not part of my assumption and you might be right.
