Default Tire Sizing Help

Hi all,

Decided to go with some new rims on my 2003 Z06...18 front 19 rear.

Car is lowered an inch on stock bolts.

What are the best tire sizing combo's you would suggest running?

I've heard the following combo's thus far as suggestions:
275/35/18 - 285/35/19
or
265/35/18 - 305/30/19

I'm currently running a 265/40/17 and 295/35/18 setup...and I generally don't want to go to an even smaller rear tire on my Z06.

Thoughts/suggestions?

What sizes/heights in general will give the best performance and ride quality?

Thank you kindly.

Sorry...thought I posted that:

Rim's I'm looking at will be 9.5" wide front and either a 10" or 11" rear.

Thanks.

Yep, they are true...'cept for a bit of chrome peeling off of one rim and a bit of curb rash on another. Overall they still look good though.

Hit me up in a few days.

What is the widest tire you can run on a 9" rim? Can you run a 275? 285?
