I don't have 18s but have run the BFG AT KOs and currently the Toyo M/T. They both handle great at around 45 psi. My M/Ts are noisier, but I think it is because I had them sipped. Both are very tough tires, that can take a beating. BFGs are less $.TecheTitan said:
If you care about gas mileage, (some here don't), the BFG 33" AT are around 60 lbs. (285/65R18), and the 34" AT are 65 lbs. (305/65R18).
The Toyo M/T 33" are 75 lbs.
My BFG AT KOs were 58 lbs. and I lost 1 mpg over stock BFG Rugged Trails, (44 lbs.). My Toyo M/T's are 73 lbs. and I lost another 1 mpg, for 2 mpg less than stock.
The M/T's extra weight plus extra size on mine, 33.5" diameter makes my Titan seem sluggish compared to the KO, and I have the lower gears, (BT & OR pkg.).
