When the Pit Bulls were new, they rode so smoothly that we honestly couldn't believe that we were driving down the freeway on 47-inch tires. They've been on our truck for one year now, and we've learned a few things about them. The most important thing we learned is that they work absolutely great in all off-road conditions. The massive size and large tread lugs makes this tire almost unstoppable. But they are not rolling as smoothly down the road as they used to. As they aged, our tires started to flat spot, just like all big bias-ply tires we've ever tried. And with a 47-inch-tall tire, you have to drive a considerable distance to heat them up enough to round them back out. We decided our best course of action is to move the truck around a few times per week to not keep one section of the tire slammed against the pavement.
