As the name says the tubeless tyres do not have tubes. There is still this myth among people that should there be a puncture it is difficult to get a tubeless tyre repaired or it is expensive to have that repaired. Let us see how the tubeless tyres work in the first place.
The tubeless ones seal off wheel spokes about the rim with either spokes or plastic strip. And the tyre valve is sealed with a ring and tyre itself is made air proof by adding rubber to tyre or by coating the casing with butyl rubber.
It is no wonder that the tubeless tyres are expensive nonetheless they are an investment for long term saving - saving cost of continuous events of flattening of the tyres. The tubeless tyres tend to maintain pressure better than the tubed ones (in the event of a puncture there is no sudden loss of pressure and one can safely drive through a puncture wala) and are a good safety even when you drive at high speeds. They also don't get heated up fast unlike the tubed, they work towards increasing fuel efficiency, even lessens the noise from tyres
The best part about going with tubeless tyres is that they can run the bike even when the tyres are under low pressure unlike tubed ones which inevitably flatten when the bike or car goes on a nail when the tyres go below the optimum pressure. Tubeless tyres offer better grip even when there is low pressure in the tyres and the ride will have added comfort with better grip. In fact a tubeless tyre could be the best option you can give to the bike as it will lessen the possibility of flat tyre.
All said it ain't a simple thing to repair a tubeless tyre (car or bike). Even though the chances of tubeless tyres to flat are low, if you go on harsh terrains flat tyre can be an event. So you should know how you can repair the flat tubeless tyre.
Simple tips to repair tubeless tyres
Take a marker and mark around the hole. Now rotate the tyre and see that valve is pointed up. Have the tyre like this for sometime to allow the sealant to flush off the valve.
Now rotate the tyre to make sure the valve is pointed downwards. Now take off the air from the tyre because sealant would not leak off the tyre.
Squeeze the tyre wall at the center of the rim to make the air lock system loose. With a tyre lever, pull tyre off the rim and pour the sealant of the tyre into one bowl.
Wipe and dry area of the hole (puncture) using a cloth or paper. Dry the puncture in sun. Take patchy glue and place around puncture area and allow it like that for sometime. Then press the patch upon the puncture, again allow it to remain for sometime.
Now pour back sealant into tyre and attach the tyre wall over the rim and inflate the tyre and check if the puncture has been properly fixed.
Done, your tubeless tyre is good to run again. See, it is not rocket science.
While it is your choice to go with tubed tyres or tubeless tyres, a great majority of people think that they are expensive and avoid. To tell the fact, such people ignore to calculate how much they would have spent on frequent tyre punctures that happen with the tube tyres. Calculate your maths and you will make up your mind that it is sense to go for tubeless tyres (bike or car).
