tire sizes on c5z06
tire sizes on c5z06 picking up some new tires this week or next, I am going to run 315/30/18 toyo r888s on the rear, what size do i need to run on the front to keep the traction control from freaking out
I searched for it but couldnt find exactly what i was looking for, all i could remember was seeing that the rear was supposed to be like .75 to 1.5 inches bigger in diameter than the front but i dont remember if that was right or not

Looks like those 315/30/18s are actually smaller in diameter than the stockers so you probably would need to go down to a 275/35/17 considering that a 275/40 is actually larger than your stock 265/40

If you run a 315/30R18 in the rear, you are installing a tire that is .6" shorter than stock. That gives you an overall diameter of 25.5", which is almost the same as your 265/40R17 front tires. Besides looking silly with bigger sidewalls in front, your active handling may get jacked up. You want to keep the front-to-rear height stagger between .75-1.00" or so.
corvette is quite a bit different as far as wheels/tires go than f-bodys
i will also prolly need a bit more tire than a 295 cam/spray going on and a blower going on later this year

You don't need a smaller front diameter. You can run a 315/30/18 rear. 275/40/17 front. Toyo R888. The fronts are actually a little bigger. Nothing is going to "freak out". I've been running the same size diameter front and rear for years.

275/35r17 in the front and 305/30r18 in the back i believe, im getting 11.5 slicks today for the car but my rear tires are shot so ill prolly be picking up a set of 315 for the rear here soon.
