Hello Tim
The main source of wire wheels is MWS. When I fitted wires to my SP 10 years ago I purchased from SC Parts who still sell them. I suspect the wheels had the same source, but I found SC cheaper than MWS. The choice of finish is a matter of taste. Stainless steel is now popular however whilst it has obvious advantages it does seem to sparkle as much as chrome. The painted finish is the cheapest.
I fitted 5″ x 15″ tyres which are a good compromise although for the purest 4 1/2″ may be preferable.
My tyres are Fulda which I believe are only available now in low profile, but Vredstein sprint classics 185 x 15 are now popular as are Michelin XAS in 180 x 15 size. In most cases these should not cause problems with rubbing on the body. Avoid low profile and fit 80 aspect ratio.
Another option is Turrino wire wheels, the company is I believe run by a SP owner which is extensively modified.
Regards
Stewart
