Question for you all!


I'm in need of new tires, and I did some research for having a staggered set up on AWD coupes. And, I know about the rolling diameter having to be almost identical, and have come up with F 235/35 19 and R 275/30 19, which has about a 0.08% difference.

Now the question is, has anyone put bigger tires on their AWD coupe models but had just the same tire sizes all around. So instead of the stock 225s, had like 245s all around.

The reason I ask is because I'm honestly getting to a point where I'm sick of having to explain to dealerships and shops about the rolling diameter thing, and how it can work as long as the difference is minimal. Are there are pics available on the forum, with people who run bigger all around sizes? I was thinking it would look weird...

Also, is there anyone who has a staggered setup on their AWD coupe and what's the LONGEST you've gone without any issues.


Thanks in advance!!!

 

The tires on my x coupe are 20x9 +32 on the front with a 245/35/20 michelin pilot super sport tire, the rear rims are 20x10.5 +45 with a 285/30/20 pilot super sport tire. They are 0.4% difference in diameter.
I have only had the car for a year, and no issues yet.



here's a pic of the stock rear tire size vs, the 285/30/20 that i have on the rear

 

If you're talking about the coupe 19" staggered wheels (8.5x19 & 9x19) you can run 245/40/19s all around since the stagger is minimal. If you have a typical 1.5 to 2" stagger then you should run compatible different tire setsw front & rear.
BTW, those tire sizes you listed are quite a bit smaller than OEM diameter, I'd run 235/40/19
front 275/35/rear FWIW.

 

Quick answer:
Yes, you should be able to run 225's or 245's all around. Just make sure the wheel is of the proper width for whichever one you choose. (i.e. don't put 225's on an 8.5"- 9" wheel, or 245's on a 7.5" wheel, etc.)
