Tony Posted January 27, 2017 Report Share Posted January 27, 2017 Quote Mercedes-Benz UK statement issued 24/1/17 and reproduced verbatim:We're sorry to hear that a small number of customers have experienced an issue with certain models, generally at cold ambient temperatures while manoeuvring at low speed with steering lock applied. The experience is of the front tyres apparently 'skipping'. This is a comfort issue, and does not affect the safety or performance of the vehicle.This characteristic comes from flexibility within the tyre sidewall, the grip between the front tyres and the type of road surface being driven over. It is something which can be felt only at very low speeds, and when a certain percentage of wheel lock is engaged for turning. This is demonstratively more evident in colder temperatures due to the changes in the tyre rubber elasticity.Winter tyres and all-season tyres on 18- or 19-inch wheels improve this characteristic and we would always recommend their use in temperatures which fall below approximately +7 degrees Celsius. The use of 18-inch wheels with summer tyres also improves the issue.We do, however, appreciate that is not always possible or practical for customers to fit alternative tyres or wheels, and our technical experts in the UK are investigating alternative ways to help minimise this characteristic. The bit missing is the ACKERMANN effect which is not adjustable and cannot be totally lost with cold tyres. Quote Link to comment Share on other sites More sharing options...

liner33 Posted January 27, 2017 Report Share Posted January 27, 2017 Thats this ackerman issue apparently , so the guy has been told Quote Link to comment Share on other sites More sharing options...
Tony Posted January 27, 2017 Author Report Share Posted January 27, 2017 Problem MB have is sacrificial meaning the low speed Ackerman effect is ok providing the very positive castor remains. Example how often do you drive at full lock -V- how often do you drive at speed. Quote Link to comment Share on other sites More sharing options...
liner33 Posted January 27, 2017 Report Share Posted January 27, 2017 Example how often do you drive at full lock -V- how often do you drive at speed. Yes and not unique to MB and that is kinda their point ie it doesnt matter as you rarely drive on full lock , but in truth if i had a car that bad i would have to punt it on Quote Link to comment Share on other sites More sharing options...
Tony Posted January 28, 2017 Author Report Share Posted January 28, 2017 My Lotus was absolutely dire on full lock to the extent it was scary. Quote Link to comment Share on other sites More sharing options...
DaveF82 Posted January 29, 2020 Report Share Posted January 29, 2020 Hi all just wondering if anyone could recommend a tyre that would stop this tyre skipping on my C43. I’ve done some research currently unable to find a All Season Tyre in my size only Winter Tyres any guidance would be appreciated. Quote Link to comment Share on other sites More sharing options...
Tony Posted January 29, 2020 Author Report Share Posted January 29, 2020 Hi Dave Michlen cross climate seem to reduce the effect but sadly the true problem is a design fault. Quote Link to comment Share on other sites More sharing options...
DaveF82 Posted January 29, 2020 Report Share Posted January 29, 2020 Hi Tony many thanks for that it’s such a shame you just don’t expect it especially when you pay lots of money for a car do you know if it’s the same on newer models? Mine is a 67 plate. Quote Link to comment Share on other sites More sharing options...
