What to do when a motorcycle tire goes flat
A flat tire on a motorcycle feels very different from a flat on a car. The reduced contact patch and inherent instability of a two-wheeled vehicle make a flat tire significantly more dangerous, especially at speed.\n\nIf you feel the bike pulling to one side, becoming difficult to steer, or if the rear end feels loose and wallowing, reduce speed immediately and smoothly. Do not brake hard — this can cause the flat tire to lose what little traction it has. Gradually reduce speed, signal to move toward the shoulder, and guide the bike off the road.\n\nOnce stopped safely, do not attempt to ride further on the flat tire. Motorcycle tires are not designed to operate flat even for short distances — rim damage, loss of control, and complete tire destruction are all likely outcomes of riding on a flat motorcycle tire.
Tire plug kits for motorcycles
Tubeless motorcycle tires — which most modern street motorcycles use — can sometimes be repaired roadside with a tire plug kit. These kits use a sticky rubber plug inserted into the puncture hole to temporarily seal the leak, combined with a small CO2 cartridge or hand pump to reinflate the tire.\n\nTire plug kits work well for small punctures (nails, screws) in the tread area of the tire. They do not work for sidewall damage, large tears, or punctures in the shoulder area near the edge of the tread.\n\nImportant caveat: a plugged motorcycle tire is a temporary fix, not a permanent repair. The industry standard is to treat a plugged tire as a limited use repair — enough to ride slowly to the nearest shop, not to continue a long journey. Replace the tire as soon as possible after plugging.
When towing is the right choice for a flat
Several flat tire situations call for towing rather than a roadside repair attempt.\n\nSidewall damage: A sidewall puncture or tear cannot be safely plugged. The sidewall flexes under load in ways that the plug cannot accommodate. A tire with sidewall damage must be replaced before the bike is ridden again.\n\nTube-type tires: Older motorcycles and some modern bikes with wire-spoke wheels use tube-type tires. A flat tube cannot be repaired roadside — the wheel must be removed and the tube replaced in a shop.\n\nAny uncertainty about the repair: If you are not confident the plug is holding or you are far from a shop, towing is the right call. A flat tire on a motorcycle at highway speed is a serious safety risk. The cost of a tow is far less than the cost of a crash from a failed tire repair.

Roadside assistance tire coverage for motorcycles
Most roadside assistance programs that cover motorcycles include tire change service — with the caveat that you must have a spare tire. Since most motorcycle riders do not carry a spare tire, this benefit is less useful than it sounds for tire situations.\n\nWhat is useful: programs that cover towing to the nearest qualified repair facility without a mileage penalty. Getting the bike to a shop that can replace the tire is the most practical resolution for most motorcycle flat situations.\n\nSome roadside programs have relationships with mobile tire service providers who carry common motorcycle tire sizes and can perform a roadside replacement. This service is not universally available but is worth asking your roadside provider about — particularly if you ride a popular model where common tire sizes are easy to stock.
