Is there anything that would present a problem using a wheel from one side of the vehicle to the other with the 18s? Aside from the tire tread that is. I was told there were inner markings suggesting a left and right position.

Thanks for the clarification guys.

 

I think that you can switch wheels L to R. After all, they're round.

The markings are on the outside of the tires, and they are directional, therefore not rotatable unless both are dismounted from the rims and swapped to keep the direction the same.

Well said GSedanMan... Just learned that tidbit of information myself the other week. It's a small price to pay to try and even out tread way and prolong the life of your tires.
