    I know 275/35/18's work, and I am getting a set mounted tomorrow. Not sure about the 40 series though, they are just a bit taller but I would guess that they would fit..

    Sure, it would be nicer having the wheels made wider like a few of the guys have done but you can get the 275's on the stock 18/8.5 rim. I am putting on a set of the BFG Drag radials in 285/35/18's tomorrow. They will work fine, have seen them on DansCTSV's car and he has no issues..

    Re: 5200 miles and rears are toast. Question for the tire experts

    The stock tires are 26.68" tall. 275/40's are 26.66" tall.

    HDMLNIUM, why are you going with 275/35?

    I could have gone with 265/40's and been at 26.2 but since they are going to be "mainly" just for track use I figured the 275/35's would give me a little more use out of fourth gear. Since we have to shift into 4th so close to the traps anyway the 275/35's at 25.6 would be a cheap way of getting a lower gear ratio and being able to pull fourth a little longer. Just my thought about it anyway.. For street use I would go with the 40 series...

    Bill, A shorter tire will give you a little better gear ratio but you will have to shift sooner not later. You will reach redline sooner and farther away from the trap.
    Edit: Nevermind. I just reread your post. We are saying the same thing.

    Makes sense. I thought these were going on as your daily driver tires.

    I did not know that.....i guess i don't have to buy new wheels!

    Still though.....won't the tires be sticking out too much past the wheel?

    Seems like a big increase from 245 to 275!???

    Rule of thumb....the width of the tread should be in very closr proximity to the width of the inside dimension of the rim where the tire bead seats....the tire should not be more than a half inch wider at the most....a quarter inch would be better.

    Re: 5200 miles and rears are toast. Question for the tire experts

    So I still don't have an answer to my question.

    Will the 275s work on a stock rim?

    The 275s for some odd reason are cheaper than the 245s from the tirerack. I am hoping I can get the bigger ones and possibly improve rear grip a little more as well.

    Yes they can be put on stock rims. They won't work up front. They will work in the rear. A lot of people have said handling takes a slight hit with them in the back. I'm going to try it, I've got GS-D3's to put on.
