Road 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.

If for any reason you're not satisfied with a Bontrager or Trek aftermarket purchase, return the item, along with the original sales receipt to the original place of purchase within 30 days for an exchange or refund. Think of it as a 30-day test ride.
