WEATHER MASTER SNOW

I'm not a tyre expert and I don't push a car to its limits so I don't feel qualified to score these tyres but I will say this... I acquired these tyres second hand last year on the advice of my garage; they had very little wear. I drove from London to Les Arcs, Val d'Isere and Celerina and back and there was a lot of snow on the roads and I felt the Cooper Weathermaster Snows handled admirably. This year, I drove to Lech with them. 6 feet of snow but the roads had been cleared. All good until the final 400 metres of unusually steep road... I couldn't get my car up there! All manner of other cars (without chains) made it up and down daily, My local hotelier (who'd lived on that road all his life) couldn't, either. We even tried reversing up (to have more weight on the driving tyres). In the end, I had to put chains on. “Not good tyres,” was his verdict. Mine is: they're fine if driven in towns and motorways and not aggressively on ordinary (ie not very steep) mountain roads.

The tyres feel good, grip well and so on. Drive good on snow as well.
I was shocked to find at the end of the season(single) that wheels started to vibrate. I drove to a garage to balance the wheels and there another surprise - all four tyres had an uneven wear, every second knot on the outside edge of the Tyre was shorter by at least 3mm. I have never seen this before in my life. Surely it is not due to the alignment of the wheels as tyres before wear well (summer) and already did another 20k km on other tyres that wear well.
I drive most of my distance on a wet and dry highway at 140km/h (around 85mph) in Switzerland, with temperatures mostly between 0-10 Celsius. I never drove in warm days, nor over aggressive style. Had plenty of occasions to try the tyrÄ—s in the mountain roads (lots of snow and ice, Inc driving with chains).
