Tony, you are correct, the crabbing is awful, I have 19 inch wheels on mine and it is unbearable. I would have another 43 but not with the issue, that's why I have ordered a GLE. I will have a set of MB multispoke bi-colour 20 inch alloys with winter tyres (less than 2000 miles) for sale in a couple of weeks, they completely solve the issue.
