AvantSE Posted January 19, 2007 Report Share Posted January 19, 2007 High-pressure washers, as used at hand car washes, can damage tyres, warns industry organization TyreSafe. The high-pressure water jets can cause damage to a tyre's sidewalls, especially if the water is hot and if strong soaps or detergents are used; these can remove protective chemicals embedded in the sidewall. Research by German safety group DEKRA has found that serious damage can occur in just five seconds; TyreSafe says that "even tyres that appear normal after being subjected to a pressure washer may have microscopic perforations, which can weaken the sidewall and cause a possible blow-out." It suggests that only water pressures of up to 110 bar or less should be used, with the washer jet nozzle held at least 20cm from the tyre surface, and that a fan nozzle (which disperses the jet) should be used to clean tyres rather than a circular one. The water jet should not be held on any one area for a prolonged time, and should not be aimed directly at the join between the tyre and the wheel rim...

bpsmith Posted January 19, 2007 Report Share Posted January 19, 2007 So the jealous ex-missus will need a portable generator and drum of shampoo/water mix along with her pressure washer to slash your tyres from now on then!?! ;-) Link to comment Share on other sites More sharing options...
