I have them and I hate them. They shudder under light braking, but are smooth under heavy braking. They are a little loud depending on the surface of the road, but no big deal. They throw everything on your paint. Prepare yourself for scratches. They don't roll smoothly, you can feel the tread and at slow speeds the truck doesn't roll very well. It's like they are chocked, it's hard to describe. I can't wait for them to wear out, I want some MTZ's.
