1997 OBS F-250 4x4. I am needing and wanting new tires for my truck. The current tires are street tires. Any time they sense mud or grass, they just want to spin and not grip. Wanting to get something that grips in the mud and when I am trying to pull my boat out of the water. I drive the truck only about once or twice a week. Don't put that many miles on it. I have the stock rims on it now. Any recommendations? While I am at it, anyone recommend any aftermarket black rims?
