Tubeless ready
A properly set up tubeless system lets you run lower tire pressure for better traction, added confidence, and a smoother, faster ride.
MTB tire pressure recommendation
Find rider weight and match it with your tire width to find a recommended tire pressure. It can be helpful to set the front tire up at a slightly lower pressure. If your tires feel too soft or too firm, add or remove pressure to dial in your tire pressure for your surface. The recommended pressures are guidelines. Do not exceed the maximum rated pressure indicated on the sidewall or rim. Follow the rim manufacturer's recommended pressure ranges for your rim width/tire combination.
Sealant recommendation by tire size
Follow the sealant recommendation for your tire size to get your tires set up tubeless and ready to ride.
