Default Wheel setup help?

I'm planning to buy some used 20" AME wheels...here are the specs below...please let me know if i will have any problems with this setup.

FRONT 245/30/20 - OFFSET 35 - 20x9
REAR 275/30/20 - OFFSET 35 - 20x10

Is it okay to have this spec for this setup?
Is it going to rub on my front or rear fenders?
Will my rear be sticking out too much due to that the 275 size?
Is my tires going to wear out uneven with this setup?

Thank you for your inputs...

I'm running

Front: 245/35/20 --- 20 x 9 40 offset
Rear: 255/30/20 --- 20 x 10 40 offset

Not sure about the rubbing with 275.. I have no rubbing issues in the rear. Minor rubbing in the front only when I turn left when the road dips.

with those widths, offsets, and tire size, you will need work done in the rear to avoid rubbing. especially if you lower your car. the wheels are on the aggressive side, if done right it won't look sticking out

also, you realize your tire sizes are wrong right? you either should do 245/35 and 275/30 (overspec), or you do 245/25 and 275/30.

and tire wear has more to do with whether you lower your car or not

thats the exact tire setup im running. ive asked a whole bunch of 3GS owners that are lowered on 20's and thats what they run too!!?!?!? the tires have worked for me but i agree, +35 in the rear is gonna need some pretty major work to the rear fenders. thats too aggressive for me.

just bite the bullet and be like Stormforge and run 25 series!!!!

oops, actually i had a typo in my post, it should be either 245/30/20 and 275/25/20, or 245/35/20 and 275/30/20.

245/30 and 275/30, nothing will stop you from doing it, but front and rear diameters don't match with each other, the rear is 1" larger. on the 2IS that's a different story coz' factory spec is already like that, but on the 3GS, the front / rear overall diameter are supposed to be the same.

25 in the rear is ok, 245/30 front has the SAME profile side wall anyway. initially i had my doubts on 295/25/22 on my ls460l too, but after running it, it's cool

I am curious what difference it will make to run the tires as they are other then the front will rotate more often then the rear but its RWD just like the IS so I dont see how it would affect anything if you used it as is and burned through those tires then put the correct ones so you are same diameter front/rear.

Its what I would do anyway....Only thing it could throw off IMO is the ABS or VSC if the system sees that the fronts are spinning faster then the rears are but for the slight difference I am sure it wont do anything.

if you are getting it as a package, i wouldn't worry about the tires until they wear out and you have to change it. there is no "big" issue with these tires, just that they are out of spec (front and rear) and your car has a rake look.

it's just like asking what if i run 19s front and 20s rear. you can say it's personal preference, but it's not something i will touch. i leave that to cars like nsx
