Looking for opinions on using 18x10.5 rear wheels front and rear with R888 275/35/18 in front and 305/35/18 in back. The front tires are 25.7 in and the rears are 26.3 in. That makes the rears .6 in taller than front and should eliminate potential problems with TC. Also Tread width is almost identical to stock ZO6 tires. I ran R888's on my Impala in 275/40/17 but this is my first Corvette so trying to avoid expensive bad choices.

Based on my research on the site those sizes are commonly used. I am considering NT01's in the same sizes, many have commented on their long life and heat cycle tolerance for the money.

Are you keeping Active Handing/traction control "on" while on the track? If so, keeping the 0.5” height difference makes sense.

If not then a true square setup helps with maximizing tire life. The 295/R18 allows you to rotate and flip the tires on the wheels to eek out every dollar.

Do what's right for your comfort level in regards to the Active Handing button vs what your wallet might prefer.

Good luck!

the Toyo R888's fit best on an 18x10.5" wheel using their 295 tire. Their tires run a bit wide and the 305 is more like a 315. You'll find their 295 is more like a 305. If you look at the measured rim width category on TireRack, you'll see this firsthand. Measured rim width on the 295 is 10.5". I currently run these Toyo R888's on the factory wheels, and the 305 tires I have are a bit wide on the factory 10.5" wheel.

I would not recommend using their 275 on an 18x10.5 wheel. You'll stretch it a bit, as 9.5 is the measured rim width. It'll work, but you can do better for not much more money...

I'd recommend the same thing as tmtraylor, and run 295's on all 4 corners. The tires will fit PERFECTLY, and you'll have the added benefit of more neutral handling and the ability to rotate tires.

Thanks for the input. I'll go 295's all the way around.

If this is your first time in a Vette I would recommend buying a set of Bridgestone RE760's in stock sizes and wear them out to learn how the car acts before I went to a R compound tire.

This is good advice.

and depending on the track layout these probably will not last very long anyway!

I run the R888's on my Impala SS which is the reason I was looking at them. The ZO6 is a different animal and I definitely do not know how to drive it. Would it be worth shaving the RE760's ? Thanks for the input.
