Traction Control Needed...

IT really doesn't matter. If it's narrower it will cup the tread depending on the tire pressure. If it's wider it will flatten it out.

Ever see a dually? They run 265's on a 6.5" tire and guys put 12.50's on those wheels.

I run 11.25" wheels on a recommended 10" wheel tire.

Maybe it would work, but wouldn't it be a bad idea? Make it handle weird, maybe defeat the purpose of the width? I don't want it to look like I'm running sport bike rear tires on the back, because the wheels are so narrow they pinch the tires into a round shape! :D
