Ken- No. I've never bothered to memorize that aspect of rims. But a good guide line might be the rim's width and age. generally the narrower the rim the narrower the intended tire would be. Some of the mid/late 70s Mavic rims were wider then current ones and IIRC had shallow tire seats, Mavic Montherly (sp?) comes to mind.
If your desire is for a wider tire only then just mount it on your existing rims. The wider tire will contact the rim along each side of the tire seat providing good support. It's when the tire is too narrow that it only contacts the rim along the center of the tire seat (a single line of contact) and allows squish down (the "noise") or tire migration on the rim. ----- Original Message ----- From: Ken Freeman To: Andrew R Stewart Cc: Ken ; classicrendezvous@bikelist.org Sent: Saturday, October 31, 2009 12:19 PM Subject: Re: [CR] Tubular tyre diameter
Andrew, can you identify a few vintage rims with seating beds that are suitable for wider tires?
