The Daily Telegraph’s motoring agony aunt recommends motorists follow his three-point plan to protect their car from ripping out the inner walls of its tyres after driving over speed bumps.
Honest John is also urging vehicle owners to back his campaign to have “vicious, car-destroying obstructions” removed before they cause more deaths due to tyres blowouts.
This is what he told his newspaper column readers yesterday:
“Metre-wide, chamfered-edge speed cushions are a relatively new phenomenon devised not to impede the progress of fire engines and large goods vehicles. They were very briefly and inadequately tested by the TRRL in 2004, but never tested for their long-term effect on car tyres.
It’s clear that if a car straddles a speed cushion with both inner sidewalls on the chamfered edges of those speed cushions, the combined forces are bound to damage the inner shoulders of the tyres. Since this is hidden damage, cars could be driven with tyres about to blow out.
My life-saving three-point plan of action is:
1. Every motorist should regularly inspect the inner shoulders of their tyres.
2. Never straddle a speed cushion – drive one wheel over the obstacle and one wheel on the road, alternating from hump to hump where possible.
3. In 2007, 46 deaths were directly attributable to blowouts and many more may have been.
Since the numbers of speed cushions have risen since 2007, the number of deaths caused by tyre damage by them must also have increased.
Campaign to have these vicious, car-destroying obstructions removed before they cause more deaths due to tyre blow-outs.”
