Meh, they're both straightwalls. I assumed they were hook/clincher beads. This explains why I was getting a bulge around my valve-stem.
The blowout on the rear is about 5" long.
I think my old bike (GTX 1000 dept. store bike from the mid-80's) had clincher steel wheels. Not chrome though.
How about 27" tires that (with an appropriate wheel) can handle over 100psi?
