    Great Tube

    I use this tube on all my bikes and all my buddies bikes. They hold up great in our Nevada desert terrain. Never had a flat yet on these tubes. I do replace the tubes every time i replace a tire.

  • STI Roctane XD Radial ATV Tire

    STI Roctane XD Radial ATV Tire

    Unsure of STI's Quality Standards

    This is my second set of Roctanes. The first was for a Cam Am Outlander, the second for a Maverick. The Good- great looking tire with aggressive tread design. They perform great on rocky and muddy trails like those found on the Hatfield and McCoy trails. I never lose grip in any situation, which wasn't true with stock Can Am tires. The Not So Good- Roctanes don't consistently hold tire pressure. Two of the four tires on my Outlander lost air at the bead. After 1-2 days in the garage, they'd be flat. On the trails, they'd loose half their air after a day of riding. The new set I just bought in September is doing the same. This most recent set visibly doesn't look plum to the rim of the STI rim they are mounted on. Both of the 8 inch wide tires on the front lose their air. After two sets of these things have leaked on me, coupled with a friend who has had the same experience, I wonder if they aren't manufactured to a tight size tolerance. If you put a bottle of Slime into each tire, the bead leaks stop. But it is annoying to have to put a $12 can of stop leak into a new tire that cost over $100. Bottom line is that if you are going to ride Roctanes, bring a portable air compressor.

  • STI Black Diamond XTR Radial ATV Tire

    STI Black Diamond XTR Radial ATV Tire

    TIM in NJ


    purchased these to go on my scrambler 850. ordered them on a set of sti hd3 wheels. i went with 26x11x14 in the rear and 26x9x14 in the front. even with the same size tires the quad sits a little higher up and is a huge improvement from the terrible stock tires. tires looked awesome and came quick but on the first ride they made it about 10 min before the side wall sliced in two places. I've never had a 6 ply tire rip so easily

    awesome wheels

    ordered these wheels for my scrambler 850. They fit perfect, just make sure to order the lugs with it. The description doesn't say that they're required over the stock ones but they are. for mine it was 10mm x 1.25 with the 14mm head. Threw a set of STI black diamond tires on and it makes the quad look and ride way better.
