    33" Chicane RX tires

    Nice fit looks great, handles great in the desert . I was thinking the 33" was going to be to large a tire but once installed it was fine. Rocky mountain was great shipped same day it was ordered.

    Great tires for Atv

    Good tires I got 3600 miles on the rear tires before I bought another set for the rear the fronts are still going and have 3/4 tread or more. I ride a can am 1000 xtp with alot of drifting around corners and show it no mercy. Good all terrain tire works well in all conditions if they accel at one thing I would say in the snow they have the perfect flotation without digging so much. The best thing about them is they flex awesome and make for a smoother ride I run about 4-5 psi in them. I ride on the grand mesa in Colorado alot with the trails being very rocky they help smooth out the ride a little bit. Good tire instead of all the new awesome 8 ply tires out there for side by side that are way to stiff for an ATV. No side wall damage yet and I put one plug in the tread section so far. If I had one complaint it would be they kinda oversteer compared to some tires I've had in the past could also be machine related to. 27-11-12 and 27-9-12. No rubbing issues and I would say they pretty much run true to size.

    STI Sand Drifter Rear Sand Tire

    Spencer in CA


    I was just extremely skeptical about buying these paddles because I had previously bout some sti San wedges and I hated them so much but I didn’t have money for skats or stu’s. I bout these hoping they would be okay but they were better than okay they worked amazing out in glamis. I absolutely recommend these. I have them on a 2016 Polaris rzr xp4 1000 turbo
