Tubeless Road Tires(11 posts)

I was thinking, why not create tubeless road tires? Run a rubber strip over the spoke nipple entry holes (kinda like an airtight rim strip) and just let the pressure hold the tires in place like on a motorcycle. Imagine how fast flat fixing would be on a tubeless road bike! I doubt the design would save weight, if not add weight, but as one who gets pinch flats on the Atlanta iron plates they pave the roads with now, I'd like anything that minimizes pinch flats and quickens flat repair.

This setup is real popular over at mtbr.com. Don't see why it wouldn't work on the road.

I did it on my commuter road bike for about 6 months last year. I'd do it again but they need to make a rim strip to fit road rims like on the MTB ones, then it will work great. I run it on my MTB and it's been great.
Don't we already have tubeless road called tubulars? (nm)Breakfast

There were Clement tubeless tubulars in '80s. I had one. NMSpunout

Tufo's are technically tubeless. Tubeless clinchers on a roadbike like the ones used on ATB's would be too heavy. The big advantage on ATB's is that you can run them at lower pressures without pinch flats. Low pressure riding is not an issue on road bikes. Cyclo Cross---Hmmmmmm!
Hmm, so, when you get a bad flat, it costs $50 not $5. (nm)Spunout

They say tubeless, but they have an inner "liner". It's a damn tube; who are they fooling?

BTW, Ksyriums are the obvious choice for attempting a road tubeless tire -- no spoke holes.

Short description = a lot of frogging around and it didn't really work out. The challenge was in establishing & maintaining the tire/rim seal. Also, if you ever do flat on the road, re-establishing the rim/tire seal could be a serious challenge if you got any junk in the seal area. If you designed a new rim and tire, like was required for MTBs, then you have all the compatibility problems and likely a significant weight increase, again like MTB. If you're getting pinch flats you either need more pressure, wider tires, or more careful riding.
