You have recently advocated the use of winter tyres and I am exploring this possibility for next winter. I would prefer to buy a new set of wheels and tyres, and whilst there is a wide choice of tyres and alloy wheels, the Internet has revealed little information about where to buy new steel wheel rims. Would steel rims be a cheaper and acceptable option or must alloys be used. I drive a Nissan X-trail with 17-inch alloy rims using 215/60 Pirelli STR tyres, but would prefer to buy 16-inch rims, as these would give a wider choice of winter tyres. Your advice would be appreciated together with any details of steel wheel rim stockists.
