SCRUBBING MAD

Motor (Australia) - - FRONT END. LETTERS -

I own a Mercedes-AMG C43 coupe and am a bit puz­zled by the front tyre scrubbing when turn­ing at low speed. This is­sue seems to have been dis­cussed a lot on fo­rums, but mainly in the UK and re­gard­ing the GLC43.

Are you aware of the is­sue in the

C43 and do you know what Mercedes re­sponse to the is­sue is? I have a client who has the C63 and ex­pe­ri­enced it as well, so I am guess­ing it is not an is­sue with the 4MATIC.

With 20,000km driven to date, the front tyres are ready to be re­placed due to the scrubbing on the out­side of the tyres. In re­al­ity, I prob­a­bly should have re­placed them at 10,000 but it seems there is no fix to the prob­lem. Would ap­pre­ci­ate any in­for­ma­tion you might have on this is­sue.

via email Dar­ren, Mercedes-Benz says it’s nor­mal. It’s called ‘tyre skip’ and is caused by the forces placed on the tyre’s outer parts near or at full steer­ing lock at low speed. It’s got to do with sus­pen­sion ge­om­e­try and ap­par­ently is most com­mon in cold con­di­tions. There are other vari­ables. Mercedes told us the dif­fer­ence on tyre wear is neg­li­gi­ble.
