well I got a set of zo6 wheels, and I have 18 x 10.5 in the back and 17 x 9.5 up front.. what is the best tire sizes for a street car set up.. thinking about 315 35 18's in the back but have no idea for the front's.. this is on my 2000 z28 camaro

 

275/40ZR17 front

295 or 305/35ZR18 rear. You could run a 315/30ZR18, but that's a bit big IMHO

 

Definately get at least 275's up front I got some used Z06 wheels and the guy I got them from had 245's up front and they look rediculous. They bow in a bit and appear to stand about an inch lower than my other 17's with the 275's mounted on them. Luckily I still have the 275's from my old wheels to have mounted up front. Xsta is right on with the tire sizes he said. I have 275's on the rear and they dont hook for anything (I am gonna get some new nitto 555R's shortly).

 

Read the sticky. lots of tire info.

I have the same wheels and run 275/40/17 front and 295/35/18 rear BFG.

 

On my Fiske's they are 17x9 up front & 18x10.5 in the rear. I went with a 275/40/17 in the front & 295/35/18 in the rear. The tires are BFG's & the rear tires look bigger then a 295. The 315 would work but there is only a select few tires in that size & they are pricey.

 

thanks, I am going to go pick up the 275 40 17's, and stick with the 295's in the back.. this is just my weekend car so it doesnt get many miles put on her
