For me, the 27" tire that characterizes the '70s was the Michelin Fifty. 27x1 1/4. Gumwall, fine chevron tread, consistent quality, 70 psi.. In the later '70s you started to see 27x1 1/8 tires and Avocet appeared with their slicks. My go-to for '70s bikes with 27" wheels is the beige sidewall Panaracer Pasela though we also have two bikes with beige sidewall Schwalbes (not sure which model, but they were cheap, like $19 on sale). The Schwalbes have a heavier, more robust look to them on both tread and sidewall. We use those on the bikes that are off-pavement more.
For a more slick tread, there are the Continentals but most what is offered now all seems to have a dark or black sidewall. I also get the impression that they are trying to cut back to one set of molds and make a single 27" tire that is in between 1 1/8 and 1 1/4. Some people grouse about Continentals but I've used a lot of them and don't really have any complaints.

I bought Kenda Street K40 tires in 27" x 1 3/8" the other day. There are not many offerings in this size. They're cheap and seem fine.

We use a lot of Kendas at the Bike Exchange where I volunteer. Personally, I think they are kind of slow compared to a Pasela or a Continental.

Sadly, I have read more bad things than good about Schwalbe's "Green" compounded tires, parts made from recycled materials.

Well, it's been eight months since anyone (me) posted to this former "sticky" thread.

I had been looking for fatter, treaded rubber for my New-Years Day Bridgestone submariner that has been seeing mixed and off-road duty, so yeah, it's being used as a "hybrid" and I finally pulled the trigger on some tires which have been impossible to source stateside.

I finally found a Hybrid "37mm" (or more realistically, their labeled and actual 1-3/8" width) tire with deeper tread than anything 27" that is actually this wide.
Previous Kenda 1-3/8" tires measured an actual 29mm on touring rims, but these Cheng Shin C-979D tires will measure an actual 35mm wide on 27" touring rims.

The tread is what I remember as the Specialized Nimbus tires that came on my 1991 Specialized Crossroads, except those were "41mm" wide (also made by CST though).

These are good tires for riding at lower pressure, though still rated for 85psi.
The tread is "open" along the center, so will wear fast in the middle if ridden at relatively high pressure (that's not what these tires are about imo).

The source is Alibaba, and the shipped price is just $17 each (I bought six). Two weeks delivery approximately, wrapped three to a package and unfurled into straight-looking tires none the worse for their travels.
Alibaba's search engine wastes your time, a 27" tire query brings up hundreds of bicycles.

Pictured mounted on a medium-narrow rim that's 15mm inside width, so only showing 34mm outside width at rated pressure, after 24 hours.

In all fairness, there aren't a lot of new developments in the 27in tire space.

Thanks for the report on the new tires.

Can you give us a link? When I search for "Cheng Shin C-979D", at AliExpress, I get a page of sex toys.

Most of my go to roadbikes are vintage 27", so another shout out for Swift Tire Sand Canyons in 27x1 3/8. They are only available via the Swift Tire web page I think... Not Schwalbe thick and uber strong, but for me, lighter and more supple for a better ride on my local bike path and fine gravel rail trail. Those or the Panaracer offerings in 2 smaller 27" sizes. For my bikes, $36 for Sand Canyons isn't terrible in today's market for what you get. And yes, I also hapilly run Kenda K40 gum walls on a motobecane mirage (beater bike) because they are always available when I need tires.

I posted the link to the particular Aliexpress vendor. You'll have to scroll through a lot of their listed products from there, but their pictures help a lot (and are more indicative of what you are looking for than their text ACTUAL SIZE is).

I entered the search term "CST 979D" in the Phoeny bike shop Store 's search box (upper RH corner).
One of the item descriptions in the search results will list 24" and 26" versions of visually the same tire, but clicking on that listing shows seven different versions, including 27x1-3/8"
There is no hard link to the particular item selection, you have to go through the search box to get to it.

Again, the store link, below:

what name brand tires came on a 80 Royael???

dddd

I worked at a Fuji dealer around that time, I'm remembering Mitsuboshi Silver Star on some of the sport-touring models.

But the Royale being fairly heavy and still having 27" rims, possibly Panaracer or IRC.

What tires did yours come with?

64TBOLT

Kenda's

dddd

The Kendas wouldn't be original, so it matters not what the original tires were, since you can't buy them.

The Canadian-Market 1976 Bridgestone Submariner I bought at Goodwill on January 1 still had it's original front gumwall, "The Original High Pressure Tyre" or some such.

I rode the bike with it's badly decaying "tyres" for some weeks before replacing them one night after riding it home on a pinch-flatted rear tire. I was running 55psi on- and off-road for my 145lbs and neither tire blew (sigh).

Panaracer is still around

I bought a Fuji Royale in 1980. While you could find a gumwall tire that resembles the original, you can get much better tires for only a few dollars more. I would go with a Panaracer Pasela. They are readily available in 27 inch sizes and not expensive. There are cheaper tires, but they are heavy and do not hold up as well.
