Went to Tires Unlimited here in Victoria. As I say they would have done it if I insisted but started talking warranty, safety, etc. The rims are stock 49 at 4.5 inches. They insisted on me having a 6 inch rim for best results. Funny thing is they installed a set of house brand same size tires (with tubes) on my friend's bone stock 51, about 3 years ago.
