Repairing a tubeless motorcycle tire in a workshopTires are important. They may only have two points of contact, each the size of a credit card, but they're the only two contact patches you get. When it comes to tire architecture, there's a clear classification – tubed and tubeless. There is no confusing the two, unlike all-season and all-weather tires for cars. It was the tubed tire that came first. Early pneumatic motorcycle tires were a two-piece affair due to rubber chemistry still being in its infancy. You had a tough, abrasion-resistant outer casing that could take a beating from the road. Inside, you had a softer, supple, airtight rubber balloon shaped in the form of a round tube that held the pressurized air. Using a single piece of rubber wasn't really an option, thanks not to the tire technology, but the rim. Before alloy wheels, wire-spoked wheels were the norm, and the wheel rim had a dozen holes in it to lace up the spokes. This meant that the rim was not airtight, and to hold air, a separate tube was needed.As metallurgy and manufacturing improved, manufacturers could make precise, single-piece cast alloy wheels. Without spoke holes leaking air like a sieve, engineers figured out that they could ditch the heavy inner rubber balloon. They created a tire with an integrated airtight bead that seals aggressively against the rim. Thus, the tubeless tire was born, changing motorcycling tires forever. In fact, America got its first tubeless tire in 1947, even though the manufacturer, Goodrich, didn't even make tires for the first 25 years of its existence. Bead sealing and thermal mass: why modern engineering prefers tubeless tiresA Kawasaki ZX-10R with tubeless tires on the highwayLet's dive into the pros and cons of tubeless tires first. The biggest advantage of a tubeless tire is its safety in the event of a puncture. If you are cruising down the highway at 75 mph, and a long screw pierces your tire, a tubeless tire won't immediately deflate. That's one reason why car tires switched from tubed to tubeless designs. The thick tread in a tubeless tire tends to hug the foreign object, creating a slow, manageable leak that gives you plenty of time to pull over safely.Another advantage is the ease with which you can repair a tubeless tire puncture. It's often simply a matter of plugging the hole with a sticky plug from the puncture repair kit, and you don't even have to remove the tire from the rim. If you travel to remote places on your motorcycle, a tubeless tire puncture repair is one of the easier DIY jobs you can do on the go. You simply have to invest in a pocket-sized puncture repair kit and some CO2 cartridges, and you're good to go.What's more, tubeless tires also run cooler and weigh less because there is no friction or mass of an inner tube rubbing against the outer tire casing. Less unsprung mass means your suspension can react faster to road imperfections, improving handling. However, if you bend or crack your tubeless alloy rim, you will lose your tubeless tire's airtight seal. Once the tire bead is broken or the rim is deformed, your tire goes flat, and no amount of sticky plugs can help. Because tubeless tires are dependent on on a perfect seal between the rubber beads and the metal wheel lip, even a minor dent can cause mysterious pressure drops over time. Tensile flex and pneumatic isolation: the structural reason tubed tires still rule the dirtRiding an enduro motorcycle fitted with tubed tires on the dirt trackThe tubed tire is the unsung hero of dirt riding. Why would you ride off-road with tubed tires? Because off-road riding demands wheels that can take a brutal beating without shattering. In this scenario, spoked wheels excel over alloy wheels. They flex, bend, and absorb violent impacts that would snap a rigid cast alloy wheel in half. Since spoked wheel rims require an inner tube, tubed tires are preferred for hardcore enduro riding. You could argue the merits of cross-spoked wheels that can accommodate tubeless tires. However, if you smash your wheel against a rock and bend it out of shape, it compromises the rim seal and deflates the tubeless tire. That isn't the case with a tubed tire; it will still hold air. Even if you deflate your tire for deep sand riding, a tubed tire will not leave you stranded if the bead slips off the rim.If you sustain a puncture at high speed, however, a tubed tire deflates instantly, causing a sudden blowout that can cause you to lose control of the motorcycle. Also, fixing a tubed tire puncture in the middle of nowhere is physically taxing. You need to remove the tire, then separate the inner tube from the outer tire, patch it up or swap it for a new tube, and stuff all of it inside the outer tire without pinching the tube. It is a gruelling, time-consuming exercise that needs a whole toolkit and tire irons.Ultimately, choosing the right type of tire depends on your riding profile. If you are riding on track or on the street, stick to tubeless tires. If you are riding through tough trails and jumping logs, you are better off with tubed tires. Want more like this?
