Tires/tubes for Rigida 13-19
Fairly new to terminology and sizing, apologies. Can't seem to find much information on these rims.
An old thread here mentioned Panaracer Paselas 1-1/8 and Paselas 1-1/4. I'm assuming any tire up to 27 1/4" will fit for this rim? For example, Gatorskin hardshell 1 1/4 (I'm riding in NYC so need something relatively durable). What about tubes? Will any 700c tube fit? What math do I need to do here for the different tire sizes?

No math needed but being able to make a direct measurement after the tire is mounted might prove to be enlightening (about labels VS actual numbers). Rims can fit a wide range of tire widths. I like a tire that's slightly wider then the rim is, in the best of worlds. Tubes will stretch a bit to fill the space they are in. The 8mm of diameter difference (630 VS 622) is well within a tube's ability to handle. I do like to match the tire's width with that of the tube's.
Take care in taking too much faith in the labeled sizes of tires. There's no tire size police so a brand can label their tire whatever they wish. If their marketing plan needs to be able to claim the lightest tire for a size then the brand might use the labeled size for their ads needs more then the rider's. This was quite common in the 1980s and 1990s, these days the differences tend to be less but still are there.
Better shops should let you test mount a tire to check for frame and brake clearances before you commit to buying it. Andy

I had thought that the 13-19s were a hook edged rim, memory fails me. My 1320s were. They were also rather a "soft" rim that suffered from rim dents easily so air pressure and tire profile are factors to pay attention to. For non hooked rims the only real max tire pressure test is just that, test before riding. The fit of tires on rims ranges so widely, the amount of tire bead and rim side wall overlap, that most any formula will fail at some point with another combo. Have a few spare tube on hand doing this test and maybe do it when the wife is out (as well as your cats
). maybe tell your neighbors that the sounds of exploding tires is not gun fire. Seriously the only way is to find out.
To reduce the pressure needs the wider tires are the way. Andy
If my memory is working better now the 13-19s were Rigida's match to Super Champion's Mod 58, which did have hook edges, but the 13-19s didn't. A nice lower cost rim but as I began to learn this stuff (in the 1970s) I moved onto hooked rims for their obvious advantages in tire retention. Most all modern tire pressure levels are labeled with a hooked rim as the "industry standard" mounting. I would reduce the air pressure by 10 to 20% from the max as a start. Slowly pump up to this in steps with checking the bead seat rib and rim top edge to track the seating. Leave the tires for a day or two, and not in a cool basement, to insure initial casing stretch isn't an issue.
