    STI Black Diamond XTR Radial ATV Tire

    confused about sizing

    The first thing is that my tires came in very fast. But when it came to selecting a tire, the more i read the more questions i had.I do not have any miles on these STI Black Diamond XTR tires ( 27x9x12 & 27x11x12) yet but they look good and i wanted to give everyone a idea on the sizing/weights.I had Bighorn 2.0 ( 26x9x12 & 26x11x12) with 500 miles on them and plugs in the sidewall. The tread depth on all 4 bighorns were 5/8".The tread depth on the STI are 1" not the 1 1/8" as stated. All 8 tires had 10 PSI in them for these measurements. The rear tires are the excat same diameter even with the tread depth difference. The front STI is 1/4" taller on total diameter. Also both of rear wheels weighed 39 lbs.The front STI was 36lbs and the 2.0 30lbs. The 2.0's with a steel wheels and the STI with a aftermarket aluminum. I guess this means these 27" STI's are actaually smaller than the 26" 2.0's not counting tread depth? Glad i went with 27's. Hope this helps someone.

    Great all around tire

    First ride 30x10x14 Roctane did very well at Royal Blue TN . We had a lot of muddy conditions, and plenty of rocks and tree roots. Was in 2 wheel drive most of the time, very impressed with the tires, was running 8 psi in the rear and 6 psi in the front.

    Worst Tires We've Ever Used

    We have an off-road tour company with a fleet of 14 UTVs. We have used just about every tire out there and these tires are the worst we have ever used. We put them on the front of a few of our UTVs and we wore through the tread in less than 2 months. Very disappointing and we do not recommend buying this tire unless you are always running in soft ground.

    2005 Honda TRX450r mx quad

    These tires seem to hook up very well on semi hard pack terrain, however they loose a lot of traction in deep/ soft sand. They are very light and have a good resistance to punctures due to the 4 ply design. The tread seems to last very well and clean out mud. The cornering is very smooth and they give you a controlled slide around corners on a mx track. They are a low cost tire but they work just as good as a more expensive mx tire
