    STI has built the Roctane XD Radial to be a high performance, durable juggernaut. The 8-ply rating and heavy denier nylon cord make the Roctane a design meant specifically for heavier, faster, more abusive applications . The tread design also promotes toughness with the Rocwall sidewall, wide tread belts, and extra-deep RocGuard rim guard, all giving the Roctane an extreme amount of protection and durability. Finalizing this tire’s stout design is the specialized tread compound meant to extend lifespan even further. With features that make the Roctane wear like iron, the best aspect is that you still get a tire that holds onto slick rock like glue. With the STI Roctane XD Radial you get some of the best wear and performance available for your machine.

  • Designed for harsh UTV applications
  • 8-ply rated with heavier than standard nylon cordage
  • Features STI’s exclusive RocGuard and RocWall to protect the sidewall and lip
  • Proprietary tread compound is formulated for extended wear
  • Excellent grip on slick surfaces
  • Wide profile footprint delivers quiet operation and precise control

Perfect !

Comments On Dec 09, 2015:These tires are exactly what my Ranger needed! Fast shipping, fits perfect, could not ask for better experience. Much to my surprise, the ride did not suffer near as much as I would have expected from going so much more aggressive than stock.

Great tire

Comments On Nov 04, 2015:8 ply radial that hopefully will hold up to the rocky trails we ride. Nice tread pattern and seems to be holding up pretty well.

Unsure of STI's Quality Standards

Comments On Oct 01, 2015: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.

Excellent Tires

Comments On Sep 15, 2015:We purchased these tires as we wanted a well rounded tire for some harder surfaces, some sand, some snow and maybe a little mud. Now here we are 13 months and 1000 miles later. They are wearing well and have never let me down. We are very satisfied and will purchase these again!
