Review on Panaracer Fat B Nimble MTB Tire: Amplify Your Off-Road Adventures by Kirk Womack

I have mounted these tubeless tires on 50mm rims these have been some of the toughest tubeless tires I have mounted if you don't have a heavy duty supercharger to beat the ball I to assemble would say not even try. The width is closer to 3 inches than the advertised 3.5 inches, but that's okay. It also took me a heck of a lot of time to get them to hold the air, the light sidewalls allow for a lot of slow leaks, I had to add glitter to the sealant to keep the 15psi for more than a few days. They have a good balance of meatiness/grippy tread and low rolling resistance, not a bad tire just difficult to set up. I would not recommend it for heavy/aggressive riders.
