Tyres are a very important part of a vehicle. They aren't only round and black; they provide both the driver and the vehicle utmost safety. Importantly, they are the only contact between the vehicle and the road. The engine and brakes work directly through the tyres. Although you may have the most advanced traction and stability control systems, they are limited by the tyres's ability to hold the road. So, as a driver, you should regularly check and use proper tyres suited to the environment. Otherwise you put your vehicle, yourself, and other at risk.

Tyres play four major important functions:

• As a support to the weight of your vehicle - an average car weighs between 1.4 to 1.8 tons which is equivalent to the weight of about 30 people. The air and the build up pressure in your tyres play the important role of supporting the weight of the car plus the driver and passengers on board.
• Absorbing road shocks - the tyres, together with the car's suspension system act as shock absorbents to reduce the effect of bumpy roads felt by the driver and the passengers in the car.
• Transmit traction and braking forces - being the only contact between your car and the road, the rough surface of your tyres provide traction when your car is moving off and also, provide the necessary braking when your car is coming to a stop.
• Change and maintain the direction of travel - the tyres turn according to the turning of the steering wheels, thus changing the direction of travel.

In maintaining the tyres on your truck you should take notice in replacing them. Buying new tyres can help your truck perform better and give more ways to utilize your truck. You must select a tyres that will work for the whole year and in every conceivable driving situation. Figuring out which tyres to buy for your truck is simple and easy.

However, new tyres can be expensive. A set of four brand new tyres can amount to a several thousand of dollars. If you want to find cheaper tyres, an option is the discount tyres retailer. They sell tyres at favorable discounts. The only disadvantage is that you will have to find a local shop to mount the tyres because the tyres are shipped directly to your door. In some cases these tyres retailers offer discount in mounting and installation at a local tyres store.

Another alternative in purchasing cheap tyres is purchasing retreaded tyres. This is a fairly inexpensive way to replace tyres without having to buy a whole new set of tyres for your vehicle. Retreaded tyres are previously-worn tyres which have undergone a remanufacturing process designed to extend its useful service life. Let's simply put that they have been rehabilitated just after becoming thrown away. On the other hand, retreaded tyres are not better than car tyres, but they are found reliable as brand new tyres. If you want a set of tyres, but don't want to shell out big money, retreaded tyres are what you're looking for.
