What to Compare Before Buying

  • Wheel and rim size: Match the size markings on your current tire and wheel. The listing also names 700x36C and 700x40C as compatible sizes, but those claims do not establish fit for every rim.
  • Riding surface: The tires are described for gravel, asphalt, unpaved roads, and regular mountain biking. The listing does not quantify performance on particular surfaces or conditions.
  • Inflation: Compare the listed 350 kPa (50 PSI) figure with the limits for your tire and rim rather than treating it as a universal setting.
  • Package contents: Two tires are listed. Inner tubes and other installation items are not listed as included.

Compatibility, Size and Fit

The main size is given as 700x38C and 40-622, with 28×1.50 also listed. The product listing names 700x36C and 700x40C as additional compatible sizes. Confirm the exact size requirements for your wheel and rim before relying on those cross-size claims.

What Is Included

The listed package contains two 700x38C (28×1.50) tires. Inner tubes are not listed as part of the package.

Safe Use and Important Precautions

Before installation, check for a severely bent bead that will not recover, exposed bead wire, or other tire damage, and check the rim for burrs. If an inner tube bursts after installation, inspect the tire for damage, including broken bead wire, exposed metal, or broken casing cords, before replacing the tube.

Before You Decide

Confirm the wheel and rim size, check the inflation figure against your setup’s limits, and make sure the two-tire package matches your needs. If considering one of the additional sizes named in the listing, verify fit for the exact wheel and rim.
