Size: 33x12.5x15 I have some off-brand mud terrains right now, but my Blazer is a DD for me. I often drive from Dallas to Houston in it, so I do a lot of freeway miles too. My current tires are LOUD and it's killing me. I can't even hear my radio at full blast. I'm looking for a tire that is quieter, but also can go on the occasional mud pit without getting stuck everytime. I'm guessing I'll have to go to a All-Terrain tire, but I'm asking for your recommendations for anything that gets good off-road traction but won't damage my hearing. BTW, I won't buy any of the *.stone, BFGoodrich, or Michelin tires. I was thinking about the Dunlop Radial Rover RV, but I'm afraid it won't grip in off-road. Any recommendations?
