Different tyres have different sizes and specifications. These depend on the type of vehicle that you are using them on. So before you buy a tyre, you must know the type of tyre that suits your vehicle so that it matches your driving needs. Always remember that it is dangerous to mix different tyres on the same axle, with the exception of the spare wheel that comes with the vehicle. Buying tyres is a big decision but it does not have to be a confusing one, especially when you know how to decide which tyre to buy. You need to consider few factors such as the tyre size, type and usage conditions.
Specifications
First and foremost, you need to know the size and specifications of the tyres suitable for your vehicle. You can find this information in the owner’s manual that came with your vehicle. Also, the owner’s manual will give you information about the minimum speed of the tyre and the load ratings you should look for in a tyre. In case you do not have the manual, you could get the tyre specifications from the sidewall of your existing tyre. Usually the readings are printed in a certain format such as 220/70 S15 Z. This information is more useful when you are buying tyres online. However, if you are visiting a dealership or a tyre specialist, you need not have to know the specifications.
Summer and winter tyres
Vehicles in the UK use summer tyres as the standard. However, in the cold season, you may want to replace the summer tyres with winter tyres. These tyres have the same size and specifications but differ in tread pattern and construction. Another ever more popular option is the run-flat tyre. These tyres help support your vehicle’s weight, giving you a travel limit of about 50 miles. These tyres are essential to overcome tyre puncture situations during long journeys.
Climatic conditions
Secondly, the climatic conditions of your area should be taken into consideration before buying a tyre. Dry and wet roads interfere with your vehicle in different ways. Usually, driving on a dry road is much safer in comparison to a wet road. The more rigid the tread patterns of your tyre, the more precise driving you can experience on a dry road. The braking distance on a wet road is almost three times longer than on a dry road. On a wet road, a tyre with deeper grooves on the tread pattern helps to keep water out of the tyres. Also, the risk of aquaplaning is high in vehicles with more worn tyres, on wet roads.
Usage
Lastly, before buying a tyre, you must consider your usage conditions. Tyres are the only link between the road and the vehicle. Hence they play a vital role in vehicle ride comfort, on road handling, braking etc. City driving, highways, off–road situations or racing – each requires tyres that have characteristics specific to the road conditions in that particular environment. So be clear on your driving needs before you set out to buy tyres for your vehicle.
