while driving a
Mercedes Benz SLK 200
(245/35 R18 W) on
a combination of roads
for 25,000
spirited miles
These tires were on the car when I bought it, at 14000 milies. The fronts (225/40x18) are still the original tires I believe, so have covered 26000 miles; the rears (245/35x18) were new when I got the car, so have covered 12000 milies.
Tread depth is about 1mm above the tread bar indicator on all four wheels - so the rears have worn twice as quick as the fronts, which sounds right. The wear rate sounds about right too (though I should try to keep a lighter right foot).
Grip - in the dry, great; in the wet, good. No complaints at all, as long as it's summer (in the UK). Once September arrives and the temperature starts dropping below 10 deg C, they become a liability. Even in the dry, if the temperature gets much below 9 or 10 deg C, then be very careful. I only have the 'baby' SLK; what it would be like in a 350 I hate to think.
Fortunately for me, the tires are low on tread and it's August - so I'll be wearing some different rubber before the colder weather comes.
