I have 35"x15.5" wide swampers and they grab everything on the road. They do get a little wild sometimes, you just have to pay attention at all times. Otherwise you will be all over the road. They wear out steering components quick! My steering's pretty loose now, but it is an 84' so it's kind of old. They are awesome tires though, they do well off-road and they look great. I will definately buy them again.
