Hi Ian,
I have fitted Yokohama BluEarth ES32 195/65/R15 to my Plus 4 also with stainless wire wheels. I got them from Blackcircles and had them fitted locally. I went for a higher 65 profile tyre to improve ride quality and ride height. They are fine for my style of driving which is not very fast these days.
Finding a fitting shop that could balance wire wheels took a little research and New Elms in Shaftesbury did this for me. Excellent service from both Blackcircles and New Elms.
Bob.
