I have some Torque Thrust II's in a size 17x9.5 for fronts and rears for my 2001 Camaro Z28 what will be some good size tires to run on them for my Z28with stock suspension, I would like to get BFG KDW's?THANKS

 

275/40/17 is the correct tire size for 17x9-17x9.5" wheels

 

275/40/17 I love my nitto 555 and 555r

 

What about the front wheels?TTHANKS

 

Since you indicate the wheels are the same size front and rear, it would be reasonable to run the same size tires front and rear = 275/40-17. That's the stock size on the SS and WS6 coupes.

 

What do you think about 245-40-17 on the fronts and 275-40-17 on the rears?THANKS

 

A 245/40-17 would be an inch small in diameter than the stock tires and the 275's you are putting on the back. Not a good idea, would look way too small for the car. Additionally, it would looked very "stretched" on a 9.5" wide wheel.

Not a good choice. If you want "skinny" tires in the front, use narrower wheels.

 

What about a 255-40-17, the front wheels have a 255-45-17 on them?THANKS

 

You want the tire diameter as close to stock as you can get them. If you want the 245's, use a 245/45-17. That would be identical to the diameter of the 275/40. But BFG recommends a 7.5" min to 9.0" max wheel width in the KDW 2 line.

A 255/40-17 would be 3/4" smaller than the 275/40. A 255/45-17 would be about 1/2" larger than the 275/40, and is OK on a 9.5" wide wheel, but I don't see that size in the KDW 2.

 

Stop. Do what the man says and put 4 275/40/17's on the car. It will look correct, and make tire rotation easy.

 

My thoughts as well. If I was looking at buying a used fbody and saw 245's or 255's on 17" wheels I'd walk away.
