Weight of the OEM 18x8/18x9 wheels?

I was getting at the actual diameter of the tire needs to stay the same for ABS and whatnot to function as designed. And of course, to keep your speedometer

I was getting at the actual diameter of the tire needs to stay the same for ABS and whatnot to function as designed. And of course, to keep your speedometer right.

This will answer everything...
Tire Size Calculator - tire & wheel plus sizing

If you plug in any of the 3 factory wheel options, you'll see they're all just over 26.5". If you want to run another size like 275/40R18, you can plug different sizes into that calculator until you come up with a near 26.5" diameter.

A few points worth mentioning:

1) Tires do not all weigh the same
2) Tires will affect handling just as much or more than wheels
3) I use a smaller diameter wheel/tire combo and have never had problems with the traction systems (on track or street).
