First off lemme say hello to all. I just joined. Nice asylum you have here. Love what you've done with the place. Since I just picked-up an F800GS I now find myself an asylum seeker. So first thing I did was go out and order up some TKC-80s. But having never owned a dirtly bike that could also run tubeless tires I've been reading-up on TL vs TT versions of tires. I've read several rubber discussions on here and elsewhere to the point my head is now spinning like a whirling Dunlop. I've come to understand that you can run tubes in a tubeless (TL) constructed tire and of course you would run tubes in a tube type TT tire--which is apparently designed for spoked rims. It's also my understanding that the main difference in TL and TT tires is the casing on a tubeless tire is slightly thicker than on the TT. Maybe there are other differences, I don't really know. So here's my question to anyone who enjoys this sort of head spinning... Assuming a TL tire fits a spoked rim, is there any real reason to ever run a tire designed for tubes when a tubeless tire would work just as effectively and perhaps offer even more puncture resistance as they are slightly beefier? Why do tire manufacturers even offer two versions? Are TT more supple or something or is it a speed rating deal maybe? Thanks for reading.
