Quality tire with good grip and smooth riding
Replaced a worn out rear Kenda Small Block Eight 26x2.35 tire with this. It's slightly narrower (2.25) but it works and feels great while riding!

Great tire!
Good price. Arrived quick in a large box. I've done hundreds of tire changes so it went on easily, using just my hands ✋️ Smells, looks and rides like fresh rubber with gear grip for my front tire! Would recommend to a friend!

Quality product
Great product. Easy install. Couldn’t be happier. Good quality for the $$ and NOT folded in box.

Great tires.
Ordered two, one came USPS in a box the size of a large TV, the other UPS the next day. Curious why they didn’t ship together.

Good bang for the buck, don't over inflate.
Bought these tires to replace some cheap Schwinn mtb tires I had on my bike after losing traction on a blue-black downhill and falling. I think the tires are good bag for the buck. The tires are wider and have a taller profile compared to other tires, which should help soak up some bumps. The side walls are thinner compared to my previous tires so it'll be interesting to see how they hold up. They tires look good and I feel that they provide plenty of grip. One thing I found on wtb website is that the recommended psi min to max is 30-45 psi for the comp tires, and even lower for the tubeless tires. I have mine set to 35 front, 37 rear. The other thing to consider if using these with tubes, make sure your tubes can inflate to 2.35 since these are wide tires. I'll update this after I try them out on the trails.

The Best
I ride very rough trails and ive slashed many side walls but not these wtb tires there invincible i seem to be able to get 35 lbs of pressure in them with a hand pump but to be honest they love that pressure and stick to everything like glue I love these tires and to remind you im a hard core mountain bike rider with with a 1000 watt moter backing me up E bike thank you WTB your the best

Smooth installation and ride
Very good quality for the cost. Taller than most tires, better shock absorption. Rides smooth, no problem installation.

Great looking tires
I was rebuilding a 2008 Novara Aspen which came with similar tires. Tires were changed to city slickers over time but I wanted to restore the bike to its original MTB look. It originally came with 2.24” 26” MTB Raptor which can no longer be procured. These tires fit just right. I woul not be able to use tires that are any wider because of how they fit between the seat stays and next to the front derailleur. Thee tires are recommended for rims with min internal diameter of 19mm, but my bike’s WTB rims are 17mm. I contacted WTB and they said that these tires would work fine. Which they did. When tires arrived each in its separate large box I noticed that sidewalls were soft and creased. WTB said that that would go away once tires are mounted and inflated. This also was correct. I used Bell MTB standard valve tires. Installation was very easy. Tires do create some noise on the pavement but it is not terrible and there is not much vibration because nubs are closely spaced. My son loves these tires and the way they make his bike look. He rides it mostly on pavement and rarely goes on grass or dry loose dirt. In a few months since installation we didn’t have to inflate tires again.

29” tires in 30” box . No need to flatten or inflate for a couple days to get a round tire. Comes rim ready round!!! Not loud on pavement, good rolling and grip I find good all around, great in dirt. Will purchase again

Es una buena llanta para clima seco aunque no la usaría para XC pues es mas bien robusta, resistente a cortes y pinchaduras con un buen agarre es buena para descenso en climas secos, no tan buena cuando hay hierva y un poco pesada

Do not buy this. Its better to buy a RALSON tyre worth 600 rupees. This product is just hyped and nothing. The air pressure PSI is hardly 35
