What is the benefit of tubeless tyres over the same with tubes?
Less heat buildup and goes flat slower if you get a puncture
the correct spelling is TIRES, it is easier to repair a flat tire that is tubeless, you can plug a leak from a puncture from the outside in some cases. with tubes you have to remove the tire from the wheel and patch the tube, then you have to feel around the inside of the tire to see if there is anything that would cause the tube to puncture again, this needs to be removed and the hole left behind in the tire needs to be patched from the inside before you can re-mount the tire and put the tube back in. that as you can see is that tubeless is much better than tubes.
Tires might be correct in the United States. Although it was Charles Goodyear who invented vulcanised rubber in 1844, it was John Dunlop, a Scottish vet, who invented the first pneumatic tyre in 1888. Since then, we in Britain spell it Tyre. Whichever way you spell it, it sounds the same so who cares? :-) Tubeless tyres offer several advantages, many of them to do with safety, the rest performance. If you took a heavy rubber basket ball and jammed a nail in it, it would deflate, but relatively slowly. If you jammed a nail in an inflated balloon, however, the balloon would explode. If you think about it, the integrity of your tyre/tire with a tube depended on a millimetre or so (fraction of an inch for our esteemed transatlantic allies) of easily penetrable rubber. Tubeless tyres/tires (can I just spell it the way I was taught in school?), as a previous poster has pointed out, will not explosively deflate instead deflating relatively slowly, allowing the driver to bring his vehicle to a halt before the tyre shreds or leaves the rim at which point, if you were still going at a fair lick, disaster would normally ensue. The other problem with tubed tyres is friction between the tube and the tyre. This generates heat. While most cars pootled about at 50 or so and were rarely driven at sustained high speeds, this wasn't so much of a problem as what heat was generated, could be dissipated. As speeds increased, however, heat generated became quite significant causing an increase in pressure as the air contained within expanded and local, and dramatic failures as hot spots developed. A tubeless tyre does not generate that kind of friction so can run faster. In addition, the lack of friction reduced rolling resistence and the absence of a tube reduced unsprung weight all of which improved performance and economy. Tubed tyres still have their applications, but not for modern, fast road use.
