Personal psi / tyre pressure choices

I just read that the old vintage rims (not clincher I think) like weinmann used to make only pump up to max 80-90psi. Is it true? What are the disadvantages with that? Anyone help!!!! I've got to make the choice of either lacing up a vintage 27 1 1/4 rim on some track hubs or buying modern wheels with double walls.

they are clinchers in a sense but are what might be referred to as non-hooked, i.e. they are straight sided rims.

as was said, the rim has no psi spec associated with it, this is determined by the tyre. With the old non-hooked 27 x 1 1/4 wienmanns, when I got up to 90psi (which was the maximum specified on my 32-630 schwalbe marathons) I noticed in a couple of minutes that I could see a bulge appearing somewhere around the sidewall, and the tyre climbing off one side of the rim, and the inner tube starting to bulge out. If it happens when you're riding then you are in trouble obviously....

I run them at 60psi and have had no problem (although I've only been on them a week!) could probably go a little higher but don't want to risk a blowout mid-ride.

Don't know where you're based, but I had Arup Sen build the fixed hub onto my old Weinmann rims out Ealing way, great job and great service.

I did it as part of trying to restore my conversion back to something like it's original state now that I have an OTP fixed getaround. Nice to have the old one set up as a relaxed slow comfy bike to potter about town on, particular now the weather is good, 27" rims (make me feel much higher up despite it only being mm difference), north road bars for upright position, brooks b17 narrow (really uncomfortable at the moment, still breaking it in, wish I'd gone for the wider one or something with springs).
