Mountain Bike Tyres - How To Choose The Right Tyres

By Tabetha Luquin

The kind of tyres you use on your bike is determined by what you are using your bike for. Mountain bikes can be used for a number of different terrains and disciplines that require different skill sets as much as different tyres. Get the right mountain bike tyres and they will improve your riding and increase your safety.

Tyres come with either an inner tube to keep them inflated or they are tubeless,but the question is which kind should you use?

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 advantages of an airtight seal and a stable, puncture-resistant, low-pressure performance are balanced out by the high price. You also need a clean rim and tyre to fit them, along with a big pump to inflate them.

Clean conditions are usually unavailable if the tyre has to be replaced on the trail. And even with a C02 cartridge pump you'll usually have to use an inner tube to get you home and then repair the tyre later. Also while small holes might be repairable, a big hole can mean the tyre is completely 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 get kits now to convert a standard tyre with an inner tube into a tubeless tyre. They mix a latex-based filling liquid with a rubber rim strip to seal the tyre and rim. You may have to top up the filler sometimes but the cost is less than buying a standard tubeless tyre.

You still get most of the low pressure advantages of a tubeless tyre but with a much bigger choice of rims and treads, and with only the initial kit cost and latex top-ups to pay for. They are also lighter although the same repair problems on the trail apply unfortunately.

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.
