I have read many threads of people putting a 140 width tire on the pre 91 K100's. I did the same and it seemed to work out just fine. But here is my question, has anyone put a 150 on sucessfully - on the older snowflake rims? I'm tempted to try it , worst I would be out is $30 installation. I know the smartest option is to get a newer 3 spoke wheel with a 160 on it but i like my powder coated black snowflakes too much.
