Classic & Vintage - Tire/wheel questions

Ok, most everything I've read here and elsewhere seems to indicate that this will be ok to do but I just need a little more confirmation that I'll be safe. The old Miyata I'm fixing up has straight wall rims instead of the modern hook bead rims. Will I be safe with a decent non-folding wire bead tire if it's only inflated to 70-80 psi?

And now my second question. These are 27" wheels we're talking about. I know that a lot of people riding on 27" really like the Panaracer Paselas. These certainly seem like good quality tires for the price. Any other favorites out there I should consider?

P.S. I'll be posting some pictures of my restoration of this bike over the coming months in my original thread titled "Miyata California Road." For those interested, keep your eyes peeled in this forum!

I used to run 27" straight-walled wheels with Weinmann tires at 100psi no problem - if it's a well-built wheel. But this goes without saying. If it's supporting you, it can easily take 80psi.

I have the Panaracer Pasela TourGuard tires, in 700C on my Trek hybrid (28C). They are nimble and grip at the same time. I like 'em. The only problem many people encounter, at least that I've heard of, with Panaracer in general is the sidewalls. They tend to be spotty and subject to easily ripping-out/blowing out. But I've never had this problem. But I don't ride like a maniac either - no offense.

Love my 27" Panaracwe Pasella Tourguards. They ride beautifully (very comfortable), grip well, look good and don't seem to have worn yet. A little car shampoo (not wash n'wax) in a bucket of warm water and a sponge brings them up like new. No punctures yet, not sure if I've been lucky or if the puncture resistance often talked about is for real.

I had 700C x 28 Panaracer Pasela Tourguards on my commuter until I put on the winter studs recently. I'm very happy with them. I can't wait to put them back on in the spring...

Awsome. I do plan on eventually replacing the rims since they're 3 decade old steel rims but I'll have to save up for them. Still gonna stick with 27" though.

I guess the general rule of thumb with running modern tires on straight wall rims is to keep an eye on the tire/bead as you inflate, right? You want them at high enough of a pressure that the bead is pressed firmly against the wall but not so high that the bead blows off the rim.

I have some older Specialized 1 1/8 on my Miyata 610 that I run at 95 psi. I always wonder about it when I change a tube, but never a problem
