My friend put 285's on his 8" mustang rim. According to him, 285's will fit just fine on our 8.5" stock rims on the rear. Can anyone verify this? I am about to order tires for all 4 corners. I have read all the sticky hot topic tire threads but still have a couple of questions.

First keep in mind, unlike most of you,:cool: , PRICE IS IMPORTANT! I dont want to spend more than 1000 for all 4 tires mounted balanced etc.

1. will 285's fit on the rear. if so what size should I get 35/40/45. Also what in size in the front 255? 35/40/45's?

2. if 285's wont fit I will go with 275's....what size should I get if I go this route 35/40/45? also what size in the front 255?

3. What tire do you recommend for me? I think the bf goodrich kdw 2 fit my needs, but would like input from you all. I live in florida...dont drive many highway miles nor do I drive alot in the rain. 2 key things Im looking for is much better dry hookup/traction from a dig (1st gear launch) and better traction slamming it into second (less hopping/back end wanting to slide out)

4. How long will these last.

5. I would like a tire I can rotate (at least side to side? if thats possible)

Thanks

I believe they'll fit in back but you'll have rubbing issues up front with wheel wells and suspension. I have 255/45's all around and I'm rubbing ever so slightly in the back of the wheel wells up front.

Edit - I just re-read this. We had a post confirming 285's in the back will work but with squirm evident with 275's I can guess that it only gets worse with 285's.

What if I lower the car?

A 285 tire is looking for a 10" rim. You'll have some serious buldging tire. Lowering the car will improve overall feel and handling but you'll always feel the rim "fall over" the tire until the buldge is pulled tight. If you don't race or drive over 90% than probably no big deal. But as you go to "set" the car there will be a little squirm in rear tires as the rims move over.

Ok..first thing's first. If you're looking for max grip, do not go KDW, go KD. KDs are their maxgrip tire, KDWs are rain tires.

Second, don't go over 275s on the stock rim...do not go over 275, you'll receive NO extra benefit over 275s, as the contact patch will be pulled down and you may even have a smaller contact patch than 275s.

Third, up front, if you're going to go 255 then stick with a 40series tire. As CVP has stated, and myself as well, the 255/45 does rub a little on larger bumps and heavy turns. The 255/40 should not suffer this issue.

Fourth, when you drop the car, you're losing all kinds of clearance...so all of the above may not work.

Good luck,

fifth, you can't run 255/40 in front with 275s in the back.. cuz the front-to-rear diameters are not close enough and you'll have problems with the Stabilitrac...

sixth, that leaves 245/45 in front and 275/40 in the rear... which lots of us are running and it works great!

Good point, Dreamin, I've heard of this issue but don't have any real data. Do you know what the differential in circ that will throw off the Stabilitrac?
Thanks,

0.6" or greater.

It's 0.7" for the C5 Z06

It's even tighter for the C6 Z06 AND you must have TPS's in your wheels... or all hell breaks loose.

Damn computers...

What brand tire are you running 275s with?
