How can I tell when my tyres need changing? 
            One sign that your tyres need changing is noticing a deterioration 
            in performance. For example, your car does not handle or grip the 
            road as well in poor weather conditions as it normally does, or it 
            takes longer to stop when you apply the brakes.  
          The fact that tyres wear gradually can make it difficult to identify 
            the reduction in performance, so it's best to have them checked regularly 
            and preferably by an expert. It is the driver's responsibility to 
            ensure that the tread on your tyres is not worn beyond the  
            legal minimum limit of 1.6 millimetres. UK law requires that your 
            vehicle is fitted with the correct type and size of tyre for the vehicle 
            type you are driving and for the purpose it is being used. This means 
            fitting the right tyres and for safety ensuring that they are inflated 
            to the manufacturer's recommended pressure. The legal limit for minimum 
            depth of the tread on your tyres is 1.6 millimetres, across the central 
            ¾ of the tread around the complete circumference of the tyre. 
            For safety reasons it is recommended that you replace your tyres before 
            the legal limit is reached. Many vehicle manufacturers recommend replacing 
            at 3 millimetres.  
          To make this easier to identify, tyre manufacturers mould tread wear 
            indicators (T.W.I) into the design of the tyres tread pattern usually 
            at a tread level of 1.6mm. As soon as the tread is worn to the height 
            of the tread wear indicator, the tyre has reached the legal minimum 
            tread depth and you should replace the tyre as soon as possible. 
          You should also be aware that there are many different reasons for 
            tyre wear. Your tyres don't just get worn through age and use, but 
            through emergency braking, under-inflation or over-inflation. And 
            if your wheels are misaligned, one edge of the tyre can wear more 
            rapidly than the other edge. 
          We recommend a weekly walk around the car to check the tread, look 
            for bulges or wear and to check tyre pressures every time you fill 
            the tank. 
           Looking After Tyres 
            1. Maintaining correct Tyre Pressures 
            There are three main reasons why maintaining the right tyre pressure 
            is important. The first is safety. Tyres that are under inflated can 
            overheat; and over inflated tyres can lead to poor vehicle handling 
            on the road. 
          The second reason is economy. Over or under inflated tyres suffer 
            more damage than those with the correct pressure and need to be replaced 
            more regularly. Vehicles with under-inflated tyres have increased 
            rolling resistance that require more fuel to maintain the same speed. 
          The third reason for maintaining the correct tyre pressure is the 
            environment. Correct tyre pressures help to maintain optimum fuel 
            efficiency. This can equate to lower Co2 emissions coming from your 
            vehicle than those with incorrect tyre pressures and that has to be 
            good for the environment. 
          2. Check for External Damage 
            Cuts, lumps and bumps are often caused by an impact between the tyre 
            and a kerb, pothole or object in the road. If your tyre has any of 
            these symptoms then you must have the tyre checked as quickly as possible 
            by a tyre specialist, as this sort of damage can result in sudden 
            tyre failure. 
          Wheel alignment too is a very important step in maintaining and prolonging 
            the life of your tyres. Kerbing or potholes affect your vehicle’s 
            wheel alignment settings which can lead to rapid or un-even tyre wear. 
            The car manufacturer will set your vehicle’s wheel alignment 
            at the factory, so after driving it’s worth a regular check 
            to help prevent premature tyre wear, generally caused by incorrect 
            wheel alignment setting. 
          Also, emergency braking can sometime leave your tyres with a ‘flat 
            spot’. This can be another reason for premature tyre removal. 
            It is always recommended to have your tyres checked if the vehicle 
            has been involved in an emergency manoeuvre like sudden and heavy 
            braking. If you have any concern or doubt about the condition of your 
            tyres, please ask a specialist for advice as soon as possible. 
          3. It’s a Driver's responsibility 
            UK law requires that your vehicle is fitted with the correct type 
            and size of tyres for the vehicle type you are driving and for the 
            purpose it is being used. This means fitting the right tyres, and 
            for safety ensuring that they are inflated to the manufacturer's recommended 
            pressure. 
          New regulations like Corporate and Social Responsibility and the 
            Duty of Care regulation place even greater focus on the need to carry 
            out regular tyre checks as part of a routine maintenance plan.  |
