how effective and in what terain is being lighter helpful? my sub weighs in at 6900 pounds loaded with the standard stuff. But i'am sure if i was going on a trip up to the paper country of maine , i'd be loaded to like 7250 or something. In snow and mud which is where i'll mostly be, i think light weight would be very heplful. So lets say i'am running a 14.5 wide tire with a contact patch of (rough guess) 1160 square inchs for all 4 tires. that puts 6.25 pounds per sq". if i run 16" tires that drops to 5.7 pounds which is the same as if i went from 7250 to 6612 /forums/images/graemlins/eek.gif This is all guess work math but it does show that there is a differance of over 600 pounds /forums/images/graemlins/shocked.gif So than in the real world which is better tryng to lose 600 pounds or running a wider tire? anyone got any other thoughts on this?
