I know my 69 T where likely issued with standard 15" wheels. However like so many other earlies seen at various events you see both 15" and 16" used. Arguments for the 16" might include a less mushy ride, shorter skid stop distance, more tread options, and better road handling. Personally my own set is beautiful. I am wondering with how some of you guys that have both if 15" merits the worthy, effort and cost in obtaining 15 x 7?
