In preperation for another undoubted miserable, cold, snowy winter I've been searching for some winter tyres to cope with the chaos it generally causes. My front kumho's are just about on the way out and with the rears not great either I thought it would be a perfect time to replace all four. I've found what looks like a good winter tyre at a reasonable cost in the Yokohama w.drive v903, seems to have good ratings to deal with the rain, ice, snow etc. I've got these priced at around £300 fully fitted. My question is really whether there is a good enough summer tyre that would cope well enough if we do get the predicted awful weather, it would save me having to buy summer ones next year if there was a premium tyre that can cope with all seasons. Suggestions on specific tyres would be grateful, I don't really have a set budget so open to all ideas. Just to add, my car is a 172 currently running on 195/45/16's. Thanks.
