biggest tires on 01 c5?
 

anyone know the biggest tire size i can run on my stock 01 c5 rim for the rears? would a 305 fit with no problems?

I run 315's on z06 rims and you can still fit a finger between the tire and wheel well..

hum,so nobody on ls1tech knows the biggest tire size that can be mounted with no problems on stock c5 rims? any help would be appreciated..

you should be ok with a 305, I know that with a z06 back rim the biggest you can go is a 315, and I believe a c5 wheel is a lil smaller.
Hope that helps

On STOCK C5 wheels...I run 295's. Certain brands, ast differently on the wheel. Some are wider,...etc. For example, I had Goodyear F1's(factory stock C5 Z06) and they buldged slightly. Now, I have PILOTS....same size, yet, the wheels are nearly as wide.

295-35-18's.

Haven't tried 305's yet.

I have 335-30-18's michelin pilot sports on my 18x10.5 Z06 motorsports. And yes they bulge out some but thats ok with me.

on a stock c5 wheel id think you'd have some trouble with a 305

On stock C5 (non Z06) wheels the largest size tire you want to go with on the rear is 295/35. Even this is larger than recommended for a 9.5” wheel, but it has been proven to work fine.

A 265/40 or 275/40 is recommended for the front to keep the front to rear tire height differential in the correct range (to keep the active handling and traction control functioning properly).

i appreciate the info guys..thanks.

I also ran 295's on my C-5 9.5" rims. Worked great.

I run 335/18 nittos drags on my stock Z06 10.5" rear wheels. yes they bulge a bit but hook great! I had 335/18 Pilot sports on the wheels before and they DID NOT bulge. Also 305/18 nittos fit the stock Z06 wheels perfectly.
