Are winter tyres worth it up in Coedpoeth, Brymbo and Minera?

They make more sense here than they do down in the town. The ground rises quickly out toward Minera, Brymbo, Bwlchgwyn and the Llandegla moors, and those roads hold ice and get gritted later than the main routes, so a standard summer tyre on a frosty morning is doing you no favours below about seven degrees. If you commute over the tops every day, winter tyres are the right call. If you mostly stay low and just want the cold months covered, all season rubber is usually the sensible middle ground. Compare winter tyres and all season tyres.
