Peugeot project
A friend gifted me a vintage Peugeot Competition. Its a PKN10 with a 531 frame. Seems like a decent bike. Needs new tires, rewrap the bars, and a new chain for starters. Should be a fun winter project, How do I determine the age?

What is the serial number? Peugeot serial numbers were notoriously unreliable as age indicators, but my 1980's did start with the proper B0... . Also, don't get fooled by the Swiss-threaded bottom bracket. If you fixed cup is gold-colored, it unscrews clockwise (left-hand thread), like an English or Japanese bike, rather than anticlockwise, like most French or Italian bikes. This was a very pleasant surprise with mine.
Great bikes -- sports-touring handling and comfort, ample clearance for full 28-30mm tires. If mine had been a size smaller, I would have kept it instead of giving it to my son, but at least he appreciates it.

Peugeot introduced a standardized serial number format starting circa 1977-1978, that included the month and year of frame manufacture. However, this was only for bicycles manufactured in France at one of the two Peugeot factories. Also, Peugeot often carry multiple stampings that look like serial numbers. The serial number that includes the date information will have a 'B' or 'Y' prefix. Given that the OP's bicycle carries a Competition model name, it should be from the era where it has a serial number with date information. I should also point out that Competitions were not always a PKN10. There were numerous variations with other model numbers, depending on the year and market.

I'm jealous but yeah, 28c is a good choice. Don't know your budget but I have Continental Gatorskin tires on my Peugeot and they make my ride much more enjoyable.

I'm partial to 28 mm Paselas now, but for years I rode Continental Sport 1000s that were nominally 28 but actually around 25-26 mm. Their only flaw was they were monsters to mount or dismount from Mavic rims.

A website which could be helpful, but...
I’ve dated two Peugeot bikes within a specific year range by headbadge...
The first, a UO-8 which I’ve since sold, was nailed down to an exact year based off of serial number tag riveted to the bottom of the bb shell.
The second, also a UO-8 remains vague since it’s tag is missing. It does have an aftermarket serial number on the left drop out, and a stamping under the shell...
...but apparently that’s meaningless. I’m satisfied enough knowing it’s no older than 1971, and no newer than 1974 as indicated by the headbadge...

I'm hoping someone can educate me on the difference between foldable and wire bead,

have a photo? Does it have a set of bottle cage bosses? Most likely late 70’s. Can be very difficult to tell exact year though because Peugeot, especially in the 70s, were very bad about the bikes they built not matching what their sales brochures listed. Check the pedals and the wheel hubs for date stamps. It wont be definitive, but should give you a good indication of year of manufacture. I owned a PKN10E, and still to this day have no idea wether it was a ‘79 or an ‘80. Decent bike when it comes to riding, but mine was an absolute nightmare because it was a literal mix of french and English standards, I $hit you not. Either way, those stronglight cranks are always a nightmare because of the proprietary crank puller size. It should (and I say that with a grain of salt) should, come with simplex SJ derailleurs, which were actually very good. Awesome (Peugeot branded) MAFAC Competition centerpull brakes as well. But the frame isn’t a full 531 frame. Only the main triangle is 531 and it’s straight gauge 531, not butted. No idea what the rest of the tubing is but I would geuss it would be Peugeot’s ‘carbolite 103’. Which is a high-tensile steel. Not a bad bike to ride, but in my opinion, lacks the ‘liveliness’ of a full butted 531 frame.

tires? Folding bead tires are literally tires that can fold. Pretty self explanatory. Usually the bead is made from Kevlar. Non folding tires typically have steel beads, and they are like car tires in that they are always the shape of a tire. Pretty much all lightweight road/racing tires are folding. Most heavy duty tires like cruiser tires or commuter tires are non folding steel bead. A quick google search can explain it pretty easy, if you need photos.

You hear different reports about which is easier to mount or more likely to blow off with overpressure or on a non-hooked-bead rim. I believe foldable is usually more expensive.
A tire jack makes mounting any tire way way easier without wearing out your thumbs. If your tires are hard to mount it is worth adding one to your regular on-the-road repair kit.

I'm a swearby Gatorskin user on most bikes. I ran some 28c Gators on a set of borrowed wheels on my '78 Peugeot. They worked OK, but putting on a set of 28c Paselas transformed the bike. It is still very lively, but the Paselas brought out a much smoother ride. One thing, the clearance is pretty tight, less than 1/4" from tire to chainstays with 28s. Lookswise, I like the looks of the blackwell Gators with my paint better than the skinwall Paselas on this particular bike. I know the Paselas also come in black wall. Model number is still a mystery. CL ad said PN10, French market model. Nothing in the French catalog looks like this, S/N verifies as 1978. The Stronglight TS crank had a stripped pedal thread, so I popped on a Sugino GT compact double, and it works fine. It's a rider, not a museum piece.
Blackwall Gator 28s.
Skinwall Pasela 28s.

Paselas are gumwalls, not skinwalls.
Also, a better shorthand for the 700c x 28mm tire size is your choice of either "28" or "28mm." Does 28c actually mean anything?

To be fair, the Gators just say 28mm, go figure.🤔

Most (all?) reproduction decals are sold with the headbadge having the "Made in France' script at the base, which is incorrect. Just another way of looking for originality.
Point being, even commonly-used reference material needs verifying.
