According to the environment agency almost 50 million tyres are removed in Britain each year. Many of these go into landfill sites where they take decades to degrade. This problem is set to increase as dumping by landfill will be banned from 2003.

There is an alternative. If all drivers correctly maintained their tyres, the pressure on the tyre mountain would be relieved by 10 - 20%. That means that up to 10 million tyres per year would avoid the scrap heap.

Couple this with the fact that under-inflated tyres use more fuel thereby increasing fuel emissions and soft tyres become an environmental headache.

There is a quick and simple way to take firm action. Pressure Guard is a unique and clever gadget aimed at taking the hassle away from checking tyre pressures.

Simply inflate your tyres to the correct pressure, attach the Pressure Guard valve cap in place of your regular cap and hey presto! An effortless way to check your tyre pressure at a glance and prolong your tyre's life.

Once over 2psi of tyre pressure is lost, a red warning flag starts to appear, giving you a simple yet accurate indication of tyre pressure loss.

Simple to use and easy to read, Pressure Guard costs just £12.50 for a set of four tyre-valve caps. Proving that being firm on tyres needn't cost the earth.
