This is an article that explains to the common man some of the basic details regarding an essential part of their motorcycle - the Tyre
Tubed and Tubeless Tyres
In simple terms, tyres which have tube in it are called tubed tyres and the ones which don’t are called tubeless tyres.
But there is more to this than what has been just said as each type of tyre is made for a particular kind of usage. For example, a tubed tyre might not be suitable for high speeds as it generates more heat than the tubeless tyre. In case there is a sudden puncture they are more dangerous as the tyre could free itself from the rim. The tubeless tyre is more suitable for high speeds and in case of a puncture there are less chances of an accident as the tyre fits more tightly on to the rim than a tubed one.
Tubed tyres along with their spoked rims can also handle tough off road conditions better than alloy wheels. One of the advantages with tubeless tyres is that the puncture can be repaired very easily without actually taking off the tyre except in the case of a puncture on the side wall.
To decide which one suits your vehicle you need to have a look at the wheel rim of your vehicle. The rims with wire spokes that go right through the middle of the rim need tubed tyres while the tubeless tyres go well with the alloy rims that are cast as a single unit. Rims with spokes that attach to its side rather than the middle, can be used with or without tubes.
Material of the tyre: Hard and soft rubber compound:
While choosing a tyre you have to make a decision if you want better gas mileage or better grip on the road. Tyres made of soft rubber compound provide a better grip but as a result, their life is also short than a firmer or hard compound rubber.
The hard compound rubber tyres on the other hand provide better mileage but their grip on road is less than a soft rubber compound tyre. The extent of grip which a tyre would provide depends upon the length of rubber molecules interacting with the surface. In case of a hard compound tyre the length of rubber molecules interacting with the road is less due to the more number of cross links between the rubber molecules whereas in case of soft rubber compounds the length of the rubber molecules interacting with the surface is more due to the less number of cross-links and this is what provides better grip on the road.
What is the Tread of the Tyre:
The tread is the patterened part of the tyre which makes the contact with the road. The tread must be capable of handling all kind of stresses as this is the part which comes in the direct contact with the road. It should grip all kinds of surfaces with least wear and tear and without heating up significantly.
A deep tread is needed for better control of your vehicle. A deep tread facilitates the passage for the water, mud or sand to go when the tyre travels on an uneven or imperfect surface. If the tread has worn out and is not deep enough then the water, mud or sand would come in between the road and the tyre causing your motorcycle to loose the contact with the road and thereby resulting in loss of control.
Factors which you should keep in mind before buying a tyre:
One major factor which comes into play while you purchase a tyre is its date of manufacture. As the time goes by the rubber of the tyre tends to harden and this causes the loss of grip. Due to this fact even if a tyre has not been used for a single time but is a few years old, it is better not to put it in use. A good estimation would be not to use a tyre which is more than 5 years old. It is better to buy fresher tyres after checking their date of manufacture.
Apart from checking the date of manufacture below are some of the points which one should keep in mind while going for a particular tyre:
- Will the tyre fit to the particular rim of your motorcycle?
- Is the width of the tyre within the limit to fit into the frame of your motorcycle?
- What is the maximum speed rating and load carrying capacity of the tyre?
- Recommended air pressure of the tyre
- Type of rubber compound the tyre is made of i.e. hard or soft rubber compound
There may be lots of different classification and aspects relating to tyres and what I have written above should be the minimum one needs to look for while buying them.

@2Wheeler Tyres- Thanks for adding these valuable points to the article. Ofcourse, tubless tyres have more advantages associated with them like the ones you have mentioned.
Hi nazboy!
Tubeless tyres are basically pnumetic tyres that do not need a separate rubber inner tube. These tyres are safer than tube tyres. The key benefits of tubeless tyres are that it allows cooler running and even if it gets punctured it can drive the car to a substantial distance without any jerks and inconvenience. Lighter weight of the tubeless tyre also adds worth to its usage because lighter the weight more is the fuel efficiency.
@Sujeet- You are absolutely right. A worn out tread would not facilitate the passage of water, mud or sand and this would cause the formation of layer of such particles in between the road surface and the tire. This would cause loss of traction and poor controlling of your vehicle or even cause your motorcycle to skid. When this loss of traction is caused by the formation of layer due to water particles it is called Hydroplaning or Aquaplaning.
@Dr Sumedh- Yes you are right, adding those points which you have mentioned would have added more technical details to the article. But i just wanted to keep it as simple as i could this time. I’ll take your feedback and will include it in the next one! thanks for your suggestion Sumedh, much appreciated.
I have another point to add –
if you don’t have treads, the chances of aquaplaning are high.
A short but well researched piece by Naz. You could have written about the sidewall thickness, aspect ratio, plies and other technical jargon to make it even more effective. But nonetheless, this is a good attempt.
@Greg- Thanks mate! I have tried to cover some basic information on tires which these days is very common among the bike enthusiasts. Most of the people talk about tubed and tubeless tires and also about the soft and hard compound material. So I thought to throw some light upon such aspects.
Nice post, very informative about different motorcycle tires and I will keep this in mind when I need new ones.
