Re: want some quiet tires
I have been exceptionally pleased with my Swamper SSR tires, 33x14.50. Not only are they very quiet on the highway, but they're extremely good off-road. They've held up to 2 years of trail abuse and over 12,000 miles on the highway, and only upon close inspection can I see any sign of treadwear. There are some cuts in the tread from rocks due to how soft the rubber is, but they haven't hurt the tires' traction or durability in any way. The soft rubber compound is what gives them exceptional grip, and since they're so comfortable on the street, I have a hard time recommending any other tire to anyone, except maybe a Bogger to a dedicated mudder. Otherwise, you can't go wrong with the SSR (despite what the guys at Pirate4x4 think).
