  • STI Tech 4 MX ATV Tire

    STI Tech 4 MX ATV Tire

    Bobby in Texas

    Puncture Prone

    I had read some of the reviews for these tires prior to making the purchase but once I got them on the ATV and took it out for a spin the front left tire started to loose air. Once I took it back home I took the tire off and noticed that a goat head sticker was stuck to it. Once I removed the goat head and put some water with soap over the place the goat head was at bubbles starting to appear. I was very disappointed with having one of the tires get punctured with a goat head sticker. I thought these had a good ply rating.

    good all around tire

    I LIVE IN SOUTHERN UTAH WHERE THERE IS A MIXED BAG OF COUNTRY. FROM SAND, ROCK, SNOW, AND MUD. THIS TIRE HAS PREFORMED WELL IN ALL. LOOKING TO BUY A SET FOR MY 2009 RHINO 700. ONLY COMPLAINT IS THAT TIRES HAVE SMALL AIR LEAKS, SO I JACKED UP GRIZZLY AND AIR UP ALL TIRES TO MAXXX PRESSURE AND LET SET FOR A WHILE. THIS HELPED A BUNCH. TIRES PERFORM GREAT EVEN AT HIGH SPEED, AND GREAT ON TRAILS. ALL AROUND GREAT TIRE FOR THE PRICE!!!!!!!!!!

  • STI Vortex V-Roll Rear ATV Sand Tire

    STI Vortex V-Roll Rear ATV Sand Tire

    casey in CA

    STI Pro-lites with STI Vortex V-roll tires

    These fit my 900 XP4 LE great with the STI Pro-lite wheels 14X7 wheels on front &14X9 wheels on the rear, with this set up I can get just about anywhere in the sand with an otherwise stock machine. I was able to get to the top of comp hill @ Sand Mountain NV with one passenger and to the superbowl with a full load of adults, and was also able to go straight up all but the steepest stuff at Coos Bay OR around the Horsfall camping area. Some other reviewers claimed to have rubbing issues with the V-Roll paddles but I have yet to have any problems. Rear wheels with paddles mounted weighed in @ 31pounds while the fronts with tires mounted weighed only 28 pounds.
