35\'s to 37\'s...too much for my axles? I have a 12 bolt rear and a 10 bolt front, 4.11 gears, detroit locker in the rear diff. Right now i have 35x15.5x15 Super Swamper SX's. I'm thinking of going with the SSR's and am trying to decide between 35 14.5's or 37 12.5's. How much difference in centrifugal force would there be?
