Okay...i've spent a long time trying to find the answer to this question and I'm pretty sure I've found the answer b4 but I need to know for sure since I'm ordering wheels and tires soon. Anyone runnin' 275 /30/20 all around with american racing razors (24mm offset) on a lowered (eibach) stang? Lookin' to make sure they don't rub.
I'm staggered and I'm sure your looking for the answer mainly about the fronts. Just assuring you the rears would be fine as I'm running a 285 30 20 out back.
A friend of mine ran 255/35's on the front and 275/35 on the rear with the eibach pro-kit and the a/r Razors, but I don't know if the 275 with rub or not on the front.
i would suggest a 275/35, saleens run that up front with a 275/40 out back. so im guessing you can get a 275/35 all around on 20's
275/35s should be just fine you should be good to go with the 275/35s all around. i cut and pasted this from an ebay advert for a new saleen mustang: "High performance Dunlop Spirt tires 275/35ZR20 (front) 275-35ZR20 (rear) -Saleen seven spoke alloy wheels 20" x 9" (front) 20" x 9" (rear) and here's the item # if you need to see for yourself! 230107847557. and here's a pic: good luck. . . and thanks, cause I'm doin the same exact thing!
