I'm running Mud Track radials 10.50x31 which have given excellent service, but are worn out. I'm not sure who makes them, although a local dealer (Shelby's) still sells them. I've been offered a good price on Cooper SST's and would like input. Judging by a truck on his lot which sported SST's, looks like they pick up gravel bad. I had some General Grabbers that picked up little stones so bad it cracked the paint on my front fenders; looked like a spider web. Do'nt want that.
