  • STI Outback XT ATV Tire

    very pleased so far

    i haven't had to much time on these tires, but got to test them in about a foot of wet snow with an icy base and they pulled and dug well. they do ride a little rough at slow speeds. that is expected with the lug height. my only compliant is that the tires run a little skinny compared to other tires in the same size. the traction i think will more than make up for the width. time will tell how they wear, but if they last id buy another set.

    Not bad tires

    Used these for one year and sold them, they are great for mud, but on hard pack they ride hard, not as bad as Mega Mayhems but still. Rocks forget about they make technical riding more difficult. Sold them and switched to STI Black Diamonds XTR and got out of just as many or more mud holes and ride much better.
