Good tires!!
I put them threw snow,mud,sand, and rock crawling and perfomed very well. Hi speed on my xp 900 is excellent! Cant give 5 stars because they are not true to size. mine measure 26in on my 27x11x12.

Black Diamond XTR is awesome
I've got 900 miles on these tires now and they still look new. I've ridden plenty of rocky terrain, some shallow mud holes, snow covered trails and loose gravel trails, these tires perform awesome! They also have excellent cornering bite too.

I ordered on line 4 ST1 Black Dimaond ATV tires. Tires were shipped exactly as stated by Pure Offroad. I have riden a couple of really rocky trails. The new tires replaced the factory installed tires. The tires performance EXCEEDED any expectation I had. I am extremely happy with the decisio to buy from Pure Offroad and the ST1 Black Diamond ATV tires.

Great Buy
Tires ride great on hard-pack and do well in the mud as well. The lugs are significantly bigger than they appear in the photos. Slightly heavy though

The product was delivered in one week and the price was very reasonable.

My first set is on my Rubicon with over 1500 miles on them and my second set went on my 2012 Polaris 550 Touring. The steering response is quick and precise with exceptioanl lateral control; something I find most tires lack. The tires are aggressive in mud, snow and they love rock crawling. So far the best overall tires I have had and these are my 9th set of tires. These are great high performance tires and take a beating.

great tires
I put a set of 26x10x12s and 26x12x12 on a 800 Outlander on sti hd2 rims. Tires run true to size, look great, fairly aggressive tread. Tires stick well to rocks, no problems with 8 10 inches of mud, seem to do well on hard pack. Blow sand is a little different story. In my opinion better than the set of interco reptiles I have on my rzr s. Ill write another review when I get 500-1000 miles on them but so far great tires!
