Hi, I've just purchased a new (second-hand) E320 CDi Sport '08 plate. As the weather is shockingly bad at the moment, I've not had a chance to run it since it was delivered this week. I'm looking to invest in a set of new alloys and winter tyres. However, I've been unable to get a straight answer out of the dealer as to what Mercedes recommend. So, I intend to replace the standard 18" alloys and summer tyres with 16" alloys fitted with Conti WinterContact TS 830 tyres (215/55 R16 93H). Can anyone offer any advice if this is a good option, or if I should be looking at another option? Also, if you can make a suggestion as to what I should be looking for in winter tyres, what should I go for, why, and what tyre pressures should I be running? Any help is most welcome. Kind regards, Mike.
