Lexus IS Tires and Wheels

tonyguy2000tonyguy2000 Posts: 39
Can anyone tell me that after you replace the original tires on a rear wheel IS250 if the replacement tires can be the same size to facilitate tire rotation. I don't think it can but my lexus salesman is insisting they can be rotated when you put same size tires on. he acknowledges the wheels are bigger in the back but says you can put the same size tires as the front!

    I'd pose the question at Their techs are very helpful and would be able to tell you what size tires can fit on what size rims. They're usually well informed, but since the car is pretty new, it might not hurt to know/include your wheel sizes when asking.

    Thanks for the reply but thats not what I was asking. I got 2 different answers from lexus dealers and was hoping a 250 owner has had the opportunity to change their tires since they last only 15k. I want to know if the second set if tires can be rotated like the salesman said. The backs are a bit wider with the original tires and wheels.

    I just purchased an 06 Is 250 and i wanna find some bad [non-permissible content removed] rims for it. Im new to the world of purchasing after market things so I was wondering what bad [non-permissible content removed] rims are out there that would look good on a black w/black int. IS? I kinda wanna go darker rims. But i am looking for suggestions. Also what do y'all think of the G-Spider rims from lexus?

    If you have 18" + summer tire option then you "can not" rotate these tires between front and back. They are in different "width". The front rim is about 225 and back rim is 245. IS got a staggering setup to privde better traction.

    Hope this help.
  • You cannot rotate them on the same axle either because they are directional.

    Try search them on-line.

    You could try spinning rims..

    eh would rather not. I dont care to much for spinning rims. Looking for maybe a black or dark grey/gun metal color maybe. Any suggestions?

    The front rim is 8" wide and the rear is 8.5" wide. So to answer your question in simplest terms, you could put a 225/40-18 on the rim in the back and run it. Could.

    Reasons for not doing it:

    1. Technically a 225/40 should be run on a rim width of 7"-8", so you'd be outside spec on the rears

    2. 225/40-18 (front) gives you an outside diameter of 25"; 255/40-18 (rear) gives you an OD of 26.1" - your suspension is set up for this 1" difference, even with the 17" wheels (though the difference there is more like .75"), and running the shorter, not just narrower, rubber in the back will make a dent in driving characteristics

    3. Least important, but still annoying, it will look somewhat like you are running on spare tires in the back - it will look silly.

    The staggered set-up works. The car has been designed that way. I suggest knuckling under and living with a tire purchase every 15-17K miles if you're dainty, and 10-14K miles if you're actually driving the car!

    I get new rubber every 13K miles on average. Based on sheer driving pleasure, it's worth it. Well worth it.

    Sorry, little brain cramp there: your rim width would actually be OK; 7.5"-9" for the 225. Coffee-optional morning here.

    I still wouldn't do it based on the other criteria, especially the handling/performance criterion.

    Log on to and look for wheels that match your vehicle. One of the choices is this:
    SSR GT7

    If you want to go with a dark insert, at least do it with a forged, lightweight wheel. These come in at about 20lbs, which ain't too shabby for an 18"x9. Just remember, real wheels have five spokes and more than seven basically screams either "juvenile pimp" or "geriatric poseur" in a loud, high-pitched whiny voice. IMNSHO, of course...

    Thank you wale_bate1.

    Thats the answer I was looking for, I appreciate the full explanation.

    Thanks again.

    Genuinely happy to help if I can.

    Another thought popped in here: the offset on the 8.5" rears, in order to carry the 255mm rubber without sticking out of the wells, is likely greater than the fronts. If too much moreso than the fronts, the tires will rub inside the wells at full crank. OTOH, if too little, the rims up front might actually stick out of the wells just a touch. Gives that oh-so-sophistcated air of an '84 Camaro from Compton. Mmmmm, tasty!

    Just ordered a black on black 250 should be in a week or two. I wanted to know if the Lexus Car Care Service Plan or the Lexus Road Hazard Tire Plan was worth having on the IS? Or is it a rip off?
  • lop868lop868 Posts: 7
    worth it,i just got the is350,18 inch alloy,run flat,etc...friend works for a tire company,tires run about 300 each,not including if you bend the rim,tires that come with last about 15,000 but can get eggs if you hit potholes,i got the 5 year tire plan,totally worth it,the price of 2 tires and it covers the rim...

    Thanks for the tire info, I am going to get the Road Hazard Tire Plan. What do you think about the Car Care Service Plan, did you get it? I know it included oil changes does it included new brakes? I can't remember what she said...
    actually the answer is yes & no.
    If you have staggered tires (the tires/rims in the rear are LARGER than the tires/rims in the front) then you CAMMOT rotate staggered tires. You need to keep an eye on your tire pressure(s) AND you should (read: recommendation) perform an alignment at a minimum of 2X per year.
    HOWEVER, you could mount a front tire on a rear size rim BUT it won't feel or drive right and you might get some rubbing at the fender/wheel well housing) or the brake caliper might touch the inside of the rim (NOT what you want to happen).
    The idea of staggered tires is that it lends to better performance and if you paid for the 18' tire package why would you want to change it?
    Stick to keeping the tires inflated to the proper level & the front end in alignment and you should have NO problem. Also, don't take the car to a jiffy-boob or a Midas for an alignment (or maintenance for that matter). Take it to the dealer - they have the right equiptment and the know how. You spend a lot of $$ for a premium car, don't let just any idiot work on it. That's like buying a million dollar home and furnishing it with IKEA crap! Spend the money & get it done right. Remember, you get what you pay for!

    its worthless unless youre talking about the wheels. I dont see why you wouldnt go to sears or tire rack and get the tires for much less.
  • from_flfrom_fl Posts: 113
    For those who have 18" summer tires on their IS, do you plan to replace them at lexus dealer or some where else(where)?

    Do you plan to use the same dunlop maxx tires or other brand?

    Does mounting require special know-how since this car come with tire pressure monitoring system?
