    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

    Awesome Tyres Will buy again

    This is my second set. The first are on my 2013 Rincon. Cant fault them. Tough, reliable, and a good ride to boot. i ride mostly hard pack, but when it rains in the Northern Territory, Australia, the mud is thick and deep. These tyres have not let me down yet. Of course I have been bogged a couple of times, but with a bit of weight shifting they find traction and drag me out of every bog hole I can find. Need to run lower pressures than normal. I'm runing about 2.5 - 3 psi. the side walls are very stiff and I reckon I could run them flat ( lower speed of course) to get me out of trouble. Will definately buy these again. 650kms on the last set and they hardly look worn considering the amount of circle work I do... lol. Cheers Mark

    Save your money

    Did some reading on different paddle tires and decided to give them a try. Really disappointing! My friend has the 900 as well and went with the sand stars and he out climbs me constantly and gets a better jump out of the hole. Even on the stock big horns he passed me on a hill climb. Probably be a better tire if you have a turbo or more power but you can do better for less.
