I'm going to follow your advice and use one of the firms you recommended for a set of rims and cold-weather tyres for next winter. But I am confused about sizes and speed ratings. Clearly I have to use an approved tyre size and wheel size (next size down gives better handling and more room for chains I believe?) But what about the speed and load ratings? The speed rating on the car at the moment is W and I can't find winter tyres with that sort of rating. Likewise, the load rating is higher than that which I can find on winter tyres. So presumably it isn't illegal, dangerous or against manufacturer recommendations to use lower rated tyres in the winter providing one doesn't exceed the specs of that cold weather tyre? And having received some contradictory advice already, what do you recommend as the best position to store tyres on rims during the opposite season?
