Structure of tube tire
Tube tire has the similar structure with the tubeless tire, but tube of the former is independent and that of the latter is integrated with casting tire, which can be taken as “inner liner”. The casing tire can not tightly wrap with the hoop. Once inner liner is punctured, air will flow away from the combination part and the bead will be cut off even on slow riding, hence, the tire will be disabled totally. If riding at fast speed, heavy traffic accident like rolling-over and sidelong will occur.
Structure of tubeless tire
Tubeless tire, also called vacuum tire and hollow tire, means no tube in inner. Some drivers hardly know tubeless tire and feel unreliable. In fact, tubeless tire doesn’t mean no tube in liner but it integrates with casting tire by a more scientific and advanced material and production method.
There is a seal film (chlorinated butyl rubber mostly) with high sealing performance closely attached to inside wall of tire. If punctured by a nail, air will flow away. Inside film of tire will shrink with air flow to block the puncture hole. There is no any air leak because the film is wrapped with the hoop tightly. In addition, there is only one intake, so it can not leak, too. Therefore, when punctured by nail and the same, air can not flow away totally so drivers can have enough time to handle and accident will also not be caused ( when driving at high speed, if front wheel is broken suddenly, traffic accident will occur) while casting tire not damaged by air leak.
We can make a test: blowing a balloon and then puncturing, it will blow up; but if we stick an adhesive plaster on the same balloon and repeat the test, the balloon will not blow up but be plugged by the adhesive plaster accompanied with air flow away slowly.
So, from safety angle, vacuum tire is the most ideal for high-speed vehicles. In addition, it features lower heat generation, lighter weight, fuel saving (It’s been proved tubeless tire can save 1% to 2% of fuel than tube tire) and easy to fit.
Since invented in 1930, tubeless tire has developed for over 60 years. The initial reason of development is safety. But till now, some drivers still worry about its safety, which can prove taht we are still lack of better propaganda and promotion.
Tubeless tire requires hoop no any impact, no rust and passed air tight test, otherwise, tire will not be inflated due to the failure sealing with the hoop.
