The Trail Boss Goodyear Duratrac AT tires weight 53lbs. I know when you go to a larger heavier tire it can affect ride and mileage.
The Mickey Thompson Deegan 38 has a true diameter 33" and 34" tires that are slightly heavier by only a few pounds.
Plus Deegan is a local MX rider here in SoCal...support local!!
