I think people spend far too much on tyres. I have found my Falkens every bit as good as the Dunlops, and quieter. My wife's Golf was running Nexens and, coincidentally, the E-Class estate she now drives arrived shod with Nexens as well. But the Falkens and the Nexens are about half the price of the most expensive brands, who have to pay for their costly advertising campaigns.
Incidentally, the E-class has a 3-litre V6 diesel engine and is every bit as rapid as my 1996 LS. It also uses noticeably less fuel than her 2.3-litre Golf. I have hated diseasels for years, but now I am not so sure...
