I'm about to purchase new 18" bullit wheels and KDW2 tires in 255/45 and 285/40. It just occurred to me that I won't be able to rotate these tires at all, since front/backs are different sizes and they are uni-directional so I can't even swap left/right.

So I'm SOL.... huh?

 

Yep.

 

Bummer

 

Is there anything I should do when mounting/balancing to ensure my new wheels/tires wear properly and evenly?

 

as long as you keep the car in alignment and proper tire pressure there is no need to rotate tires.

 

Don't feel bad, Porsche 911's been that way for years. (Along with a few other high-end makes)Corvette has been that way too with larger in the back,smaller up front.

 

Welcome to the world of nice cars ... Just think of it this way,You won't have to rotate your wheels...
