A cut sidewall or a tread puncture does not have to mean a new tire. GlueTread kits repair tubeless tires from the outside, bonding rubber to rubber so the damage is sealed where it sits, without breaking the bead or pulling the wheel off the vehicle.
These kits are sized for full size tires: the pickups, 4x4s, SUVs and overland rigs people drive to work during the week and take off the pavement at the weekend. The repair itself is rated for off-road use only, so treat it as the way to get a damaged tire working again on the trail, the farm or the job site, rather than as a substitute for a professional repair on a highway tire.
Not sure which kit? The External Patch Kit covers most cuts and punctures. The Sidewall Seal Kit is built for long slices and wide damage. The Complete Kit carries all three repair types in one case.
