super swamper tsl vs??

[tjcustomranger]

i have 35x15.5x15 swampers 90% tread. they weigh 84 pounds a piece.

i kind of want to go bigger. the 36x12.5x15 tires are 12 pounds lighter per tire.. does that make much of a difference in performance?

are the radial tsl any better than tsl sx? they only weigh 63 per tire for 36 inch
