Thank You for Your comment.
Are You sure about the relationship tire weight and suspension? I think that You are wrong. Suspension doesn't matter on tire weight. Tires are on the ground/Earth. So, suspension suspense ATV - "weight in motion" is ATV itself (with me) and not tires. (sorry, I don't know have write it in English. I hope You understand what I mean.)
And I think it's exactly the opposite - taller (not heavier) tire mean more rubber/taller sidewall which help suspension.
Regarding ground clearance - I read that stock tires are smaller then 25" - about 24,5" and Carlisle declare that A.C.T 26" have about 26,5". So, I will get about 1" better ground clearance.
And regarding of 26x9 and 26x11 dimension - that tires are wider = heavier ;-) what I don't want.
OK, I will look at lightest radial 25x8 and 25x10 tires.
