    Lacks control in hard turning.

    Doesn't hold up around cactus, even with Ride-On or Slime. Good traction in all conditions, but the softness of the tire is the weakness when turning.

  • STI Outback XT ATV Tire

    STI Outback XT ATV Tire

    David in New Hampshire

    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.
