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.Read All Reviews

These tires are amazing. I originally had them on a 2015 Ace 570 and now have them on my 2015 Scrambler XP1000 and these tires chew through everything. I tossed the Scrambler full-bore into a mud hole on a logging road up to the bottom of the seat and the tires had no problem pulling me out coupled with the Scrambler's power and drivetrain. If you're looking for a tire that doesn't rumble due to super-aggressive tread but is just as good as other mud-bogging tires, these are the best compromise.Read All Reviews

What I received was a tire labeled, AT 22x11x9 6 Ply. upon speaking with several call takers and sending their tech guys photos. I was told that Douglas just miss labeled the tires. HUH! These tires have been out since 2012. I ride the High Sierras, Bishop to Death valley( Highest and Lowest points in the lower 48) I state that do to the different terrain that I ride usually at high speed and I thought I had found the tire of my dreams. a RUN FLAT! Makes me wonder if these are seconds which they should be if miss labeled. Rocky Mtn. told there should be a white stamp on the side of the tire stating 12ply rated, No such stamp was located on either tire?? It should be noted that I went thru the tire builder program and had these tires mounted on Douglas 190 wheels, Several calls to Douglas have gone unanswered ? Althuogh Rocky stated they called Douglas and were told the tires were just miss labeled I m not so sure, but you can bet when I m done with these tires I will be cutting them in half to find out myself. Let me state clearly the only mistake Rocky made was (NOT) noticing the 6 ply AT, all terrain rating and calling me when the tire was mounted. It should be noted that nobody has rated these tires yet???, As stated in there product listing info the tire has been out since 2012 .Rocky Mtn is still the best place to shop for just about anything a rider might need and I will continue in the future, just disappointed in Douglas for not sending the right labeled tire to Rocky Mtn ps; Still trying to call Douglas.I have not sent these mounted tires back do to the hassle and time it would take to replace them as I plan on riding this weekend and if they are 6ply then that's what I would be getting anyway.Read All Reviews
