Review on 27.5x2.25 Trail Boss Comp Tire in Black by Jeremy Gulledge

I fixed a 2008 Novara Aspen that had the same tires. The tires eventually switched to City Slickers but I wanted to bring the bike back to its original MTB look. It originally came with a 2.24"26" MTB Raptor which is no longer available. These tires are perfect. I can't use wider tires as they fit between the seatstays and next to the derailleur. These tires are recommended for rims with a minimum inner diameter of 19mm, but the rims on my WTB bike are 17mm. I contacted WTB and they said these tires would work fine. what they did When the tires each arrived in a separate large box, I noticed that the sidewalls were soft and wrinkled. WTB said it would go away once the tires were in place and pumped up. This was also correct. I used tires with standard Bell MTB valves. Installation was very easy. The tires make some noise on the pavement, but that's not a big deal and there isn't a lot of vibration because the lugs are tightly spaced. My son loves these tires and how they decorate his bike. He rides it mostly on tarmac and rarely on grass or dry, loose dirt. A few months after installation we didn't have to pump up any more tires.
