Mountain Bike Tyres - Which are the Best Kind?

By Tabetha Luquin

The sort of tyres you choose for your bike depends on what you use it for. Mountain bikes are used for many different things over different ground, and each discipline requires different tyres. If you have the right tyres for the job they will make it safer and improve your riding as well.

Tyres either come with a standard inner tube to keep them inflated or they are tubeless, so the question to answer is which one do you go for?

The majority of tubeless tyres have a thick sidewall that fits into a specific sealed-bed rim. These tyres can handle rough ground so they are perfect for downhill, but the flip side is the cost.

The advantage of an airtight seal and a low=pressure, stable performance i has to be weighed up against the high cost. Also you need a clean tyre and rim to fit them, and a large pump to inflate them.

Clean conditions are not often available if the tyre needs to be changed out on a trail. And even with a CO2 cartridge pump you will most likely have to use an inner tube until you can get home and fix it. Even though small holes might be repairable a big hole can mean the tyre is even written off as well.

Tubeless tyres are heavier as well, so if you need to get quick start times and riding speeds go for a lighter tyre. Tyres with inner tubes are lighter and offer more flexibility. They are also available in more treads and design styles, so getting the right tyre might be easier.

You can now get kits to convert a conventional tyre with an inner tube to a tubeless tyre. These combine a latex-based filling liquid and a rubber rim strip to seal the inside of the tyre and rim. You will probably have to top off the filler now and then, but the cost is still much less than a standard thick wall tubeless tyre.

You will still get most of the benefits of a tubeless tyre but with a much wider choice of treads and rims, and with only the cost of the kit and latex-based filler to pay for. They are lighter as well, but you might still get the same repair issues while on a trail.

Whatever tyre you go for it is vital to replace them regularly. A blow out can cause injury and cost competitions. With the right selection and maintenance your tyres will make a huge difference to your riding. - 16887
