66Horse, I have Pro-Comp MT's and I can tell you that they ARE NOT quieter than BFG's. Pro-Comps are dead-silent when you first get them (siping on the tread that doesn't go down all the way!) then when the siping wears off (first 20% of tread life) they get the characteristic Mud Terrain scream on the freeway. Mine were the first batch out so they are a good tire; however, the later tires have an extremely soft rubber compound that makes them wear at an unbelievable rate. On a 2800 lb Cherokee (about 1200 lbs lighter than my Bronco) with open differentials the tires are almost gone after about 12,000 miles. As for my 33 x 12.50's on 10 inch rims, they have gone 16,000 miles and have minimal tread wear and seem to perform quite well in the rain, the Mud and Offroad. I know, I'm sending mixed signals. My Brother and I bought Pro-Comps when they first came out, and we have had phenomenal results with them. Despite our success with them, I've seen at least 30 trucks that wear them so incredibly quickly that a TSL Bogger would have lasted far longer. Just my input. Oh yeah Detroits will eat these tires for lunch if you're not careful.
