Changing oil, replacing spark plugs and preventing rust are all common ways to extend the lifespan of your vehicle. However, choosing the best tyres is another critical concern that is overlooked by many owners. To appreciate their importance, it is wise to take a quick look at how the very dimensions and materials used can have a drastic impact upon levels of safety and performance.TreadTyre tread is a major concern. Over time, these surfaces can become worn down. This condition is known as a “bald” tyre. There are two inherent problems when this occurs. First, slippage can present dangerous situations during emergency braking situations or when driving in poor weather. However, the tyre tread can actually decrease the efficiency of the vehicle and lead to higher petrol costs. If the tread is seen to be worn, it is best to replace the tyre or tyres in question.Driving ConditionsDifferent tyres are specifically intended to be used within certain conditions. It should first be obvious that city navigation will require an entirely different tyre than an off-road excursion. However, weather is another concern. For example, snow tyres retain their flexibility in cold conditions and their grooves are designed to provide extra grip when driving upon snow or ice. Without these tyres, the alignment of a car can be affected. In a worst-case scenario, skidding and accidents can be the end results.LongevityHow long a tyre will last can affect the safety and performance of your vehicle. As a general rule, all-season models will provide the highest levels of durability while specialty or racing variants can lose their tread and elasticity much quicker. It is therefore critical to know these factors in advance.These are three concerns which will all have a great impact upon the health of your vehicle. So, it is apparent that tyres represent the very foundation of safety and efficiency.
