I am getting a set of of 15x8 wheels for the rear and I want to fit as much meat as I can on them. I have a set of 275/60/15's that I am going to use for now but I am looking for how big I can go on an 8" rim. I found Mickey Thompson makes a 295/65/15 which they say will fit on an 8" but they are listed as 30" tall. Not necessarily a bad thing since At least for the time being I will be running the 4.30 gears with the F1 so I will need some tire height for trap speed sake as well as hopefully hooking better off the line. Will a 30" tire fit inside the wheel wells?

I have seen a couple of cars run a 29.5 tall tire, but I don't know about that fitting on an 8 inch wheel. But--if anyone would know they would. Are the tire specs (as far as tread width and section width) on the website?

I am getting the Greg Weld Dragstar 15x8 5.5 Backspace. Should tuck just fine although I will rather have a 15x10, these will do till I shorten my rear axle. I ordered them today for a Steal at $99/wheel.

The 15x10 6.0 BS will bolt on but stick out passed the wheel well. There is no reason the 15x8 should not fit. I got them from Summit. I will let you guys know for sure in the next day or two. Since they are only 8 inches wide you might not even need to do a swaybar relocate but I have a BMR rollbar anyway.

i know the original 15 by 10s that were released had problems with hitting the caliper so i did no know if the 15 by 8 would still have the same problem. good luck let us know.

The 15x10's that I tried cleared an 07 just fine as far as I could tell. It was hitting the swaybar bracket but looked to have good clearance for the calipers.

I'll grind the calipers otherwise, I'm tired of trying new stuff all the time that doesn't work.

You were right they do not hit. This is the first time I have tried a set of Greg Weld's on my own for the rear. Most other wheels that I have tried hit the caliper on the front face, but these are hitting the outside top of the caliper instead. Both a set of 15x8's and 15x10's do this on my car but the 15x10 cleared the calipers on an 07 that I tried them on. Did the rear brakes change between 05 and 07?

yes actually i believe the brakes did change, and the reason they do not fit i believe when greg weld made them they mocked them off of a V6. I just ordered a set of 17 inch greg welds and will have to live with them till a 15 inch comes out. just so you know a pro lite 93 series 17x9.5 weighs 21 lbs and a 17x4.5 weighs 15lbs. just some info incase you still wanted greg welds.
