Topic: Can I run a 4.0x18" rear tire on a '73 CB500Four without issues?

Stock is 3.50," judging by looks a quarter inch on each side won't affect anything but I wanted to make sure.

Thanks.

Should be fine. The 550 originally came with a 3.75x18 which is generally not available so the 4.00x18 is considered the best substitute and appears not to affect handling negatively.
