Recommend a 27 x 1 1/4 tire for straight-sided rim?
I have an old Schwinn LeTour with hookless steel rims. I'd like to buy good 27 x 1 1/4 tires for it, but I understand some are better at staying put on hookless rims than others.
Criteria in order of importance for me:
1. 27 x 1 1/4. I'm 210 lbs, need the wider tire.
2. Stays put at 85-90 psi on a straight-sided rim. I'm 210 lbs, need the higher pressure.
3. Reasonable flat resistance. (Better than the stock tires I rode on in the 70s at any rate.)
And, Low rolling resistance, Good ride, etc., if possible.
Good life in indoor storage.
Not necessary for a long-wearing tread. I don't put many miles on this bike.
And with Niagara Cycle Works out of business, what mail order house is good for these, or for a variety of reasonable price parts for older bikes?
Thanks....

I think Panaracer Paselas are the best 27” tire.

I have some 27 1 3/8 tires in my basement in the States. They work well on a few of my bikes here in Cambodia and I weigh 240. I normally run them around 65psi front and rear. They have a nice cushy ride and last a good while.
Let me know if you want some. I think I shipped 4 in a big priority box for 18.55 and $5 a tire.

+1 to Panaracer. However I returned to bikes at 350 pounds, now below 300. On 27" straight wall rims I have never needed more than 70 psi to carry me and a forty pound bike on rock hard tires, 1 1/4" or less. As long as they have wire beads, I've never had a problem.

I'm using Kenda 27x1 1/4 skin wall tires on my Rigida hookless rims on my '84 Peugeot. 90 psi. I've had them 2 years and so far, no problems.

Yet another endorsement for the Paselas. I've got 27 x 1 1/4" skin walls on straight sided alloy Rigidas and so far no issues.

If you don't mind a blackwall, the Performance Strada is a good budget buy. They're a little stiffer than the Paselas, but still ride pretty well. Better on wet pavement and gravel paths than something with that little tread should be.
I have found that i have to keep them above 70psi, or they can slip on the rim during high efforts (climbs / sprint)

Death fork? Naaaah!!
And I've used them on straight-wall Schwinn/Weinmann rims at 80-85PSI. I'm 165lbs, but the weight of the '73 Super Sport makes up for that.

Yep, I may go with the cheapo Kenda gumwall look-alikes, 'HIGH PRESSURE'. That's what's been on there for the last 10 years, and they still look like new aside from the rear getting a little thin. The ride & rolling resistance are OK, especially considering the price. Longevity & flat resistance has been ok. These were hard to seat when new so that they would ride w/o a dip, but they stretched out after some time. Thank you all for the advice.

Since tubular rims have a different profile rim from clincher rims and tubular tires don't fit on clincher rims, and since 700C is 622 bead seat diameter vs 630mm for 27 x 1 1/4", how would you go about doing that?

Along the blackwall lines, I have a pair of Specialized Road Sport 27 x 1 ¼ on my Dunlop Special Lightweight rims. I haven't ridden them yet, but they fit the rims beautifully and look good at a sidewall-rated 90 psi. Worth a look!
Regarding fear of blowoffs: From the 1930s through the 1950s, Raleigh, Rudge, and Humber produced bikes with these rims and wired-on tires by Dunlop, John Bull, and others. Examples of these bikes are the 1952 Raleigh Super Lenton, the 1952 Rudge Aero Special, and an identical Humber to complete the identical triplet.
The bikes were ridden on nearly 1000 mile runs like Lands' End to John O'Groats in record attempts, by factory-sponsored professionals and by enterprising amateurs (I can do that, all I have to do is keep pedaling!). I can't believe they used pressures lower than the rated nominal 90 psi. If they had blowoffs with any frequency, the design would have been changed, since these runs and records were key to Raleigh's sales. It was race on Sunday, rake in the cash on Monday. Blowoffs could not be tolerated.
With Paselas or this Specialized, I don't think there is any risk of blowoffs with rims and beads in good condition.
I don't have any experience with the Kendas to make a comparison.

I agree with Palincsars on the tubular substitution matter - they are not designed for 27 x 1 ¼ rims. The bed of the rim is not suitable to glue the tubular and the act of stretching the tubular to slip over the rim edges, if more severe than normal stretching, is likely to weaken the threads in the carcass with the possibiity of premature blowouts and rather dangerous flatting.

What makes you so certain that they don’t, have you tried it?
I have, I commuted on a bike set up like that a full summer.
They’re not meant to, I give you that. But it works.
Easily, for those rims I had access to.
Well, a tubular tire expects to sit in a shallow trough.
IME, it doesn’t appear to be particularly inconvenienced by being mounted in a deeper trough.
I wouldn’t like to try clincher tire on tubular rim though.
This is what makes it work. 700C rims have the brake track at the same diameter regardless of being tubulars or clinchers. The bottom of the trough has a bigger diameter for the tubulars.
630 mm clinchers have a greater brake track diameter than the 700C, so the bottom of the trough tends to end up pretty darn close to the diameter at the trough of a 700C tubular.
I did have two issues though. The 630 mm wheels I used most looked a bit like the
https://www.skywaywheels.com/ and these had a really deep trough. With the tubulars I had - 23 mm - the tire became very recessed into the rim. Pinch flatting became a risk.
I also tore the valve stem on one tire as the tire slid on the rim.
The sliding was easily dealt with by adding some double-sided sticky tape to the inside of the rim.
Not enough tire protrusion could have been solved by either a wider tire, filling up the trough(which probably would have fixed the sliding too) or simply by using a more traditional metal rim w/o that unusually deep trough.

I wouldn't recommend using a tubular tire on a clincher rim unless perhaps it was an emergency.
You'd be getting pretty much the worst features of both types at the same time, but still saddled with the heavy rim and impracticality of puncture repair.
I've used clincher rims to stretch tubular tires though so I know the tires fit, and there was an albeit very heavy "Mixte" rim produced which was made for both tire types to be fitted. Again though, it brought forth few of the advantages of either system and was obviously optimized for neither.

Why I'm shying away from the Panaracer Pacela Tourguards. Several Amazon reviews say the sidewalls are weak, that they deteriorate and fail in the weather or maybe even indoors. I bought a set some years ago for a bike for my niece. I recall seeing the bike some years later and being negatively impressed at the condition of the tires. And, they didn't appear to be very flat resistant, and I think some reviewers commented on that. Good ride, yes. But without reasonable flat resistance and longevity, no go.

I'd take the amazon reviews with a grain of salt. I read those too before I bought some, and they have over 5000 miles on them now, including inappropriate trail riding. The kevlar belt stuff helps with glass cuts, but if you run over a nail, you're going to flat. Mine held up pretty well. Paselas are relatively light tires, so if you're looking for a rugged commuter or something, they aren't the best choice. Schwalbe and Continental are options.
Any tire can potentially blow out if a brake pad is rubbing them, or they take a hit from a pothole edge or sharp rock, or they are run under pressure.

Both the Bontrager T1 and T2 tires are available in 27x1-1/4. When I bought my Viva Sport a few years ago, it had a pair of Bontrager T1 tires on it, but in 27x1-1/8 on unhooked rims. That wheelset and tires got moved on to my Fuji S-10S. I had commuted on those tires for the next three years. BTW, I weigh in at right around 200 pounds, and ran them at 85psi front, 90psi rear.
That said, the Viva Sport got 27x1-1/8 Paselas PTs when it got a new wheelset in the refurbishment. My Univega Gran Tourismo (touring bike) got Paselas PTs in 27x1-1/4.

If they will fit you might consider 27x13/8", more volume is a good thing. Personally I'm enjoying a nice ride with Continental Ultra Sport 27x11/4", measure 31mm on Wolber 19mm internal rims. Almost as wide as my touring bike's Nashbar Streetwise 700x35mm tires which measure only 32mm wide! This is quite typical, most of my 27x11/4" tires measure only 28 or 29mm.

Thanks for your recommendations. The Kenda on the rear has suffered a casing failure & so the issue is forced. The one bald spot reported earlier was joined by a 2nd bald spot that quickly became a lump & worn-through to the cords. I guess I won't be going with Kendas again. Aside from the two areas of casing failure, there was plenty of tread life left on the tire.
Update: It's all moot. Ordered new Schwalbes. Wish me luck.

One vote here for Michelin protek if you want a decent quality heavy duty tire. I run 27 x 1 and 1/4 pasela protites on an early 70s Moto Grand Record. No complaints as these are nice tires. I use the 27 x 1 and 1/4 Michelins on 70s era Sekine SHS 271. These are the original hookless rims. These are fine tires and measure 35c on my rims.

Good rule of thumb: Avoid folding Kevlar beads on straight-wall rims and don't go over 75PSI. Stick within those parameters and you should be able to mount most anything available.
