Since late last year we have been road testing Toyo winter tyres on a Mercedes C230. The size is 215/45/17V
The recent cold snap started very shortly after the test started and at very low tempratures the tyres performed well. However as soon as things warmed up the benefit was immediately lost and rear end traction was seriously compromised. Even on dry roads the Toyos just don’t grip like the previous Bridgestones
As is often the case, the V speed rated winter tyres one are rating slower than the regular tyres for this car. We attribute the lack of grip in warm, dry conditions to the fact that the V rated compound of the winter tyres is slightly harder and consequently less sticky. The message is clear; if you have to fit winter tyres for use in a cold climate get them off again as soon as possible when the trip is over.
