  • STI Mud Trax ATV Tire

    Not bad tires

    Used these for one year and sold them, they are great for mud, but on hard pack they ride hard, not as bad as Mega Mayhems but still. Rocks forget about they make technical riding more difficult. Sold them and switched to STI Black Diamonds XTR and got out of just as many or more mud holes and ride much better.

    Best tires I have ever owned

    I had these on. Kingquad on 26x12 and they run small measure 25.5 without a pouch. On my RZR 27x14's they measure true it size and are nearly as tall as mega mayhem 28's. Love these tires ride amazing and get you out of anything. True all around. Rock, snow, mud hardback tire.

    Great tire

    I bought these to replace some bald tires. They hooked up great in the sand. Only one trip on them so far, but they seem to be well reviewed. I just ordered a matching set for the front of the bike. If I continue to like them, I will be getting a set for my other quad (350 Warrior) ---- Cheap price, 6ply rating = right tire for recreational ATV use

    A great, cheap tire

    Bought a set of fronts for my banshee. Improved the handling, and ride. Only time will tell on durability, but overall I'm pleased for the price. They're are better tires out there, but these are a fraction of the price.

    excellent tires

    Love these tires for the price you can't beat them..pushing snow over my head lights of my 4wheeler to break trail to my deer blind and kept it in 4 wheel drive and full throttle they just kept digging like no other and when I thought I'd get stuck I didn't they kept digging and moving. Very happy with these tires my dad will be getting a set for his 4 wheeler and ranger.
