Good looking tire

Comments On Jul 30, 2014:Have not had a chance to test them out yet, just got them put on. I read a lot of mix reviews about the actual size. I ordered the 26x9x12 fronts and 26x11x12 rears. They are for sure a good looking tire, but, it is true they are not actual size. I put 10 psi in all four and they are smaller than stated, the tires say 18 psi max, so I'm sure they get the factory measurement from having them at max psi. On the bike the front measure 25x8 and rears measure 25x10, which is the only reason for the 4 star rating. So, if you are looking for a taller tire than stock go more than 1 inch bigger.

Awesome Tyres Will buy again

Comments On Jul 15, 2014:This is my second set. The first are on my 2013 Rincon. Cant fault them. Tough, reliable, and a good ride to boot. i ride mostly hard pack, but when it rains in the Northern Territory, Australia, the mud is thick and deep. These tyres have not let me down yet. Of course I have been bogged a couple of times, but with a bit of weight shifting they find traction and drag me out of every bog hole I can find. Need to run lower pressures than normal. I'm runing about 2.5 - 3 psi. the side walls are very stiff and I reckon I could run them flat ( lower speed of course) to get me out of trouble. Will definately buy these again. 650kms on the last set and they hardly look worn considering the amount of circle work I do... lol. Cheers Mark

Best Tyres Ever

Comments On Oct 25, 2013:Gidday from the Northern Territory Australia. I have to say these are the best tyres I've ridden on. I mainly do trail riding whilst I'm hunting and they have performed flawlessly over all terrain I've put them through. Not a big mudder, but they have seen plenty of it on the trails. thee tyres bite in very well. Shipping from RMATV was super fast to Australia.

Best so far

Comments On May 09, 2014:I fell in love with these tires right from the first ride. They just grip well no matter what terrain you are in. I have had numerous other tire models and non of them have performed as well in such varied terrain as the black diamonds. I must also say that pictures do not do these things justice. They look great on my machine. These are by far my favorite tire so far. So much so that I will probably order another set when I wear these ones out.

Awesome performance on a snow ride

Comments On Feb 08, 2014:I just put the Black Diamond XTR through its ultimate test, it passed with flying colors. I was on a local mountain trail riding in 12-15" of snow with some 2 foot snowdrift's thrown in. The XTR's just clawed and chewed their way to the top of every hill....I was very impressed! Lateral traction on off-camber sections was very good as well.
My dad was riding Bighorn 2.0's on a Grizzly 700 and those tires certainly did not outperform the XTR's, they did good, but not better than the XTR's.
