    Good looking tire

    Have not had a chance to test them out yet, just got them put on. I read a lot of mix reviews about the actual size. I ordered the 26x9x12 fronts and 26x11x12 rears. They are for sure a good looking tire, but, it is true they are not actual size. I put 10 psi in all four and they are smaller than stated, the tires say 18 psi max, so I'm sure they get the factory measurement from having them at max psi. On the bike the front measure 25x8 and rears measure 25x10, which is the only reason for the 4 star rating. So, if you are looking for a taller tire than stock go more than 1 inch bigger.

    Perfect tire for my riding

    I had read some reviews and talked with salesperson on these tires and was told they should fit the bill. We run in northern NH and deal with a lot of loose rock and sharp rocks. I tend to stay away from big mud. So far these tires have performed perfect for us. My wife loves how the machine climbs now. With stock tires would spin and slip around some and with these the machine just trudges up and over without any fanfare. Work ok in mud but work perfect on rocky sections. Love these tires.

  • STI Outback AT ATV Tire

    STI Outback AT ATV Tire

    Phillip in VA

    Traction is fine, fit is sub par

    The tire is very narrow, coming in at 6.75" mounted, the rim guard doesnt touch the rims there is an 1/8" gap between the edge of the tire and my rim all the way around and on both sides. The tire rides smooth and absorbs shock well but it just to narrow for a 7" rim, 5-6" rim width would be okay, but not 7" like mine. This is mounted as the front tire of a customized atc250es, Using a douglas .190 12x7 4/110 5+2

    Front good rear bad

    I bought these a while ago after one year of recreational mx track riding. NOT racing. They started cracking around the tread lugs. After not riding for a year I spend money to go ride at a track and now my rear is leaking through a big crack in the lug I could probably rip the lug off by hand. All I ride is track and in sand no rocks or any spinning on anything that would wreck a tire like this. Front tires seem good. For sand and soft dirt I find they dig a lot and bite really hard. They have a lot of traction both front and rear but I'm not even half way worn between the wear indicator and where they were brand new and now I have to replace my rear tires
