A fed-up Mercedes owner has raised a really interesting problem which affects his tyres with the Sunday Times motoring supplement.
WM, from Neasden, London, contacted the Car Clinic, and received advice that could save him having to buy a full set of tyres.
The reader explained: “I have owned a Mercedes S 320 CDI from new since 2006, covering 60,000 miles. Last September I replaced the front tyres, and now they are heavily worn at the outer edges and require replacement. Is this a symptom of faulty suspension? My Mercedes dealer said it could only diagnose the problem after fitment of four new tyres – a costly diagnosis.”
Tim Shallcross, a Car Clinic expert who has trained AA patrols and now advises the Institute of Advanced Motorists, replied: “Your Mercedes is fitted with the company’s Airmatic air suspension, a setup that gives a great combination of ride and handling. However, whereas most cars will need nothing more than the occasional alignment check (also known as tracking), yours needs the camber and caster angles tweaking to compensate for wear.
“The good news is that you do not need to have new tyres fitted before a full suspension-angle check nor is it necessary to use your Mercedes dealer.”
He adds that to check and adjust the whole suspension system should take about an hour.
