The Daily Telegraph’s campaign to get rid of speed bumps is proving popular with readers who agree they cause massive damage to car tyres.
The campaign is being spearheaded motoring agony aunt, Honest John, who has been tirelessly (no pun intended) warning about tyres-lacerating speed cushions.
A reader who emailed his support wrote: “If you consider a pair of tyres travelling over the sides of a speed cushion, there are two reasons why wear will occur.
“Firstly, the weight of the car is transferred to the inside part of the tyre and the shoulder.
Secondly, the sloping shoulder means that the edge is travelling more slowly than the bottom of the tyre, because it is a smaller diameter.
“This means the edge/shoulder is literally scraped along the speed cushion, rather than rolling over it. I have a gut feeling that the second effect is the most important.
“If I am right then there is a very serious consequence, because the rate of deterioration increases once abnormal wear has started. A.B.”
Honest John replied: “I have been making those two points ceaselessly – and will continue hammering away until we get rid of all tyre-lacerating speed cushions.”
