****Brand New Range For 2009**** According to the RAC more than 40 people die on our roads every year because of defective or improperly inflated tyres. Scores of others are injured. Tyres are the only point of contact a car has with the road. It is therefore vitally important for motorists to check their tyres regularly. Maintaining correct tyre pressure has benefits other than safety. Under or over inflated tyres suffer more damage than those with the correct pressure and need to be replaced more regularly. Under inflated tyres increase the rolling resistance that require more fuel to maintain the same speed. Correct tyre pressure also benefits the environment by maintaining optimum fuel efficiency, and reduces CO2 emissions. To help motorists maintain optimum tyre pressure, Ring Automotive has launched a new range of compressors. The range incorporates Ring's award winning compressor technology. Analogue and digital compressors are included to suit individual motorist's needs from DIY enthusiasts through to professionals. Neat tidy storage for fused 12v cigarette lighter plugs and the flexible air hoses means that all the compressors will store away easily in the car. To get the maximum performance and life from car tyres, motorists should check their tyre pressure regularly. The new Ring Automotive Compressors are an invaluable accessory to have the car.
