Default Problems Wearing? 245/275

Howdy,

I have a 2003 Track Silverstone and would like to know if I put a 275/40/18 tire in the rear and a 245/40/18 tire in the front will this cause problems with unusual wear? They would be mounted on my stock 18" wheels (Rays). Another thing, I keeps seeing people talking about TCS when upgrading to a larger tire size. Will increasing to a wider tire jack with the TC System?

8" F / 8.5" R if I'm not mistaken. Anyone try this? I was thinking of doing the same thing. Need to get rid of these crappy tires and replace them with some Pilot Sport 2's or something.

A 275 tire is over 10.5" wide. I think your wheel width should be no more than 1 inch different than the tire width. If not, your cornering abilities might get squirrelly.

245 might be wide as you can go on a 8.5" width wheel.

Wow, how does it handle? I'm looking to replace my rear tires only on my stock G35c wheels, but was thinking of 255's.

a 275 tire is way too large for an 8 or 8.5 inch rim

265 on an 8.5 is about the max.

Does the G35c stock rear wheels come in an 8 inch or 8.5 inch?

If it's 8 inch can I go with a 255?

EDIT: just read it was 8 inches...

The middle picture is my G at going thru turn 17, 80+ mph & excellerating onto the front stretch

& I can't really figure out where the 3rd picture was taken???
but i'm going really fast & turning to the left alittle

I had 255's on the rear tires for 18+ months. When I decided to put 275's on the rear I just moved my 255's to the front.

So you have a 275, 255 combo on your stock G35c wheels (8 inches) and no problems? Sounds like something I'd like to do but worry about fitment. How many miles have you been running the 275's on the rear?

Big change in performance or no? Are the tires wearing normally?

I also included a picture of the 1in spacer I put on my rear wheels. It pushes out the rear wheels, to fill out the wheelwell a bit more

the other pics are of me this past weekend at VIR.

The racing picture on the left shows a very good example of rear camber & "unloading" the rear inner wheel. You can see the tire contact patch angle. Where this helps is on the outer wheel, where right at this moment it is hopefully completely flat on the pavement, giving the most contact while that outer tire is receiving the most forces.
