There is one in Featherstone, £40 a wheel and he can remove and refit tyres and re-balance too. Its at the side of a little Mot and Car sales place just on the way up to the lights toward North Featherstone. Turn around is a day or two.
There is a place in castleford just a street up from the rugby ground but they are little more expensive however they do pearls and metallics. LSN they are called.
I've used both and havent found anyone better.
