I have a 95 eagle talon tsi AWD, I have rims that are 20x9.5 and 20x10.5 with a -7 offset. What tire sizes do I use so the overall diameter is the same since its awd?

you don't... even an 1/8th of an inch in difference will tear out the viscous coupling, or tear up driveshafts if you are running a spool... you need to have the same size tire all around...

I have seen this phenomenon in real life, and bought a car off a guy that had destroyed the diff due to it...

So can I put 245 all around even though the front is 20x9.5 and the rear is 20x10.5?

it'll be stretched a lot, but yah...

I have one question... what widebody kit do you have? DSM's aren't exactly known for fitting wide wheels front or rear... hell, I had 255's on 8" wide wheels +35 offset, and they rubbed the fenders on the rear... you are wanting to stick a wheel almost 3" farther outside than that...

The rims are actually off a widebody 350z, I test fitted the rims and they fit perfect. Itd the GT3 widebody and its extremely wide. Here is the pic of the rear wheel on the car.

I was also doing research and found that even though I put the same size tire on all four rims the OD will change because itd different size rims. Any truth to that?

nope,none at all...

the steel belt (radial) of the tire is, well, steel, and will not change diameter no matter what...

not a bad setup on that car, however I think I'd go wider than 245's if there is enough room... 265's, maybe 275's...

Thats what I'll probably end up doing and want to do but I'll have to widen the front fender just a few mm. The front rim was maybe 4mm wider then the fender. Thanks for all your help!

Well I have been doing some research and the best tire size combo I found so far is 265/25/R20. The OD difference is only 0.34 inch difference. What do you think? Can you think of a better combo.

I just spoke with Mr.Mark and he said I can also run 235-30-20 and 265-25-20 and he said the OD is still pretty close to stock.
