What to Compare Before Buying

  • Equipment and tire type: Check that the off-road formula suits the specific equipment and whether its tires are tubed or tubeless.
  • Tire width: The stated application for fat-tire bikes and e-bikes is for tires wider than 3.5 inches.
  • Amount per tire: Consult the product instructions to determine how much is needed and whether one 32 fl oz bag is sufficient for your tires.
  • Puncture location and size: The stated limit applies to tread-area punctures up to 1/2 inch. Do not assume it covers other locations or types of damage.

Compatibility, Size and Fit

Listed applications include ATVs, UTVs, golf carts, dirt bikes, fat-tire bikes and e-bikes with tires wider than 3.5 inches, lawnmowers, zero-turn mowers, and other outdoor equipment. Confirm suitability for the exact tire and equipment rather than relying on a broad vehicle or equipment category.

Important Limitations

The product is not recommended for passenger vehicles. The stated puncture size is specific to the tread area, and does not establish that the sealant can address every puncture or tire condition. Follow the product instructions for installation and use.

Before You Decide

Check the equipment and tire setup, the amount required per tire, and whether the puncture is in the tread area and within the stated size limit. This off-road formula is not recommended for passenger vehicles.
