wondering about tire sizes

I have the 245-45-17 on the front and 275-40-18 on the rear. I was wondering what size I could go up to that would give me a little more width but keep the same diamater. I don't want to get any taller but just a little wider.

275/40/17, but it needs a 9.5" wheel. Why do you want a wider tire in the front?

Well I guess I don't need to go wider on the front. I would like to go wider on the rear though.

Check out my post in the tires and wheels section. It will help you determine what you are looking for.

mvvette97:

I did it with my stock c5.
I went up to the Z06 size tires on my stock c5 rims.
Front: 265/40/17
Rear: 295/35/17

Front rim: 17 x 8.5
Rear rim: 18 x 9.5

No problems at all, same height, ride is very nice.
Went with the Toyo T1-S (whole set was $750 installed).... I hate runflats!!!

Those are not the same diameter, so you will need your PCM reprogrammed unless you want mileage to go up faster than it should.

Those Z06 sizes are not the same height, this is not to say they will not work though.
245/45-17 Overall Diameter: 25.68 in 652.27 mm
275/40-18 Overall Diameter: 26.66 in 677.16 mm
265/40-17 Overall Diameter: 25.34 in 643.63 mm
295/40-18 Overall Diameter: 26.12 in 663.44 mm
Z06 sizes are a bit shorter in overall height, about an half inch and I am not sure what effect this will have on speed or indicated miles. Also, 295/40-18 tires are reccomended to go on a min. 10 inch rear rim by the tire manufactures, although some have put them on 9.5" rims without much issue it would seem.

You can use this calc to figure how one size compares to another.
