- Casing - This is the flexible body of the tyre that comes in various threads per inch (TPI). This is the main body of the tyre which is then covered in rubber. This is normally made from nylon.
- Protection layer - To provide puncture protection, different manufacturers will use various types of material as a lining underneath the tread.
- Tread - The rubber compound that comes in contact with the road surface.
- Bead - The ridged stem around the edge of the tyre that locks the it to the wheel rim. This is made from either wire or foldable Kevlar.
- Anti-chafing strip - Supporting strip that protects the bead.
Why Change Your Tyre's At This Time Of Year?
At this time of year, the winter has normally taken its toll on your tyres and inspection of your tyres health should be carried out. This is a very simple task to do, however can be a vital one to keep you safe on the bike.
Checking For Wear- What To Look Out For?
Checking your tyres on a regular basis is important to reduce the chance of repeated flats whilst out on the road and increase your safety.
For the most effective inspection of your tyres wear, it is advised that you take the tyre completely off the rim itself. This means you can fully check the tyres tread, sidewalls, bead and on the inside surface of the tyre for wear and debris that could potentially cause a puncture or further wear to the tyre.
Checking The Tread
GLASS / FLINT
Glass, flint or other debris can become lodged in your tyre and cause punctures and speed up the rate at which your tyre deteriorates. If you find any debris in your tyre remove them and assess the size of hole it has left, if the wear to the tyre is significant then it is recommenced that you change your tyre. Checking for debris early can reduce the risk of punctures and improve your safety on the road.
Checking The Bead For Damage
As the bead of the tyre is made out of either wire or foldable Kevlar, it is normally quite resistant to damage or wear. However, hitting a pot-hole or a pavement curb can cause damage, and normally when the bead gets damaged, it’s time for a new tyre. This is because the bead is used to hook the tyre onto the rim, so if there is any damage, then the tyre will not attach correctly.
