Need some info/advice. I have decided to replace my original type rims and tires on my 54 3100 with the chrome smoothie type rims with tubelss radial tires. Want to improve the ride and handling. I want to know what width of 15" rims I should get. I don't want the tires to be too wide and possibly rub when turning. On the other hand, I think 5" wide is too narrow for ride and handling purposes, but I don't know. Finally, any recommendations on radial tire size to match the rims would be appreciated.
