We need new front tyres, original Continentals are now only just legal at 19000 miles. Would appreciate any advice on a decent reasonably priced brand as I know nothing about tyres! Most driving is on-road, but we do pull a large caravan so need to be able to get decent grip in the occasional muddy field. I have read the threads here on tyres, the Nokian WRs sound good, but I have not found a stockist. Does anyone know where to get them (Glasgow area), or which brands would be good alternatives? Tyre size is 235/60 R18 , there seems to be less choice in this size.
