View Full Version : What Tire for a Smooth 27" Rim?

I just had two tubes blow in my face. I attributed the first one to the really trashed condition of the old tire that came on the bike. I was trying to confirm that the bike it was on would work OK permanently mounted on a trainer. I figured the fabric and rubber separated from the bead, allowed the tube to come out and blew out. I removed a tire and tube from another 27 x 1 1/4 rim that I knew have worked flawlessly for over a year. I'll be damned if it didn't blow up in my face as I mounted the bike onto the trainer, I could see the tire come out of the rim and the tube blewout. That's when I decided to investigate. I had previously checked that the rim liner was intact, no spokes were sticking out, and no debris was sticking in the rim. I had a dim memory of reading about smooth sided rims that have no means of seating the bead on a tire, and that is what this thing is. It is an old Campy rim and hub. It is otherwise unmarked as to size. The original tire was marked 630/ 27 x 1 1/4.

What type of tire is required to use with a beadless rim? I searched Sheldon's site and the BF archive, but they seem silent on the subject.

Thanks for your help, and speak loudly when you respond, I seem to be having difficulty hearing just now.

Regards,
Steve

Most wire-bead tires will work; Kevlar bead/folding tires will usually not. But even with wire-bead tires, you're likely best not to go above 85-ish PSI.

+1 Wire bead and modest PSI is what is required when you have a rim that lacks a hook.

+2 Wire bead, moderate pressure. I have been picking up low end wire bead tires from Niagara for less than $6.

The wire beaded tires from Performance bike seem to fit a bit tighter than the ones from Niagara, (I use both), but cost a couple bucks more.

Install tire & tube, manually pump just a little air at a time , stopping to check that tire is seated evenly around on BOTH sides. Continue til you get to about #75. Examine all around on both sides to make sure it is evenly seated.
