Weinmann 700C Concave Rims
I have a pair of these that are in excellent shape and am considering building a pair of wheels with them. The inner side walls have no "hooks" so I'm wondering if there is a tire that would work with them. Any suggestions?

We used various tires on the narrow 124 and the wider 129 with no trouble. Try what you got.

You need tires with a wire bead (rather than a Kevlar bead) and to limit pressure to about 85 psi.

I had a Super Mirage with concave rims BITD. The tires said to pump to 90 psi, and that's what i did. Tires were Hutchinson of some sort IIRC. 90 PSI was the default tire pressure 10 speeds were expected to use.
Conti sports sound like a good bet. I'm sure there are other good candidates. Pump carefully and watch it carefully the first time you pump to full pressure. I'm not sure I would exclude kevlar bead tires. We used to put Turbos - the original kevlar bead tire - on all sorts of rims.
Michelin Elans would blow off of anything, even quasi hooked Rigidas. I hated those tires.
Maybe Panaracer Gravel Kings? I noticed those are very tight fitting. Won't fit on my A23 rims at all. OK fit on H+ Archetypes.

I am running 700x25 Panaracers on my Winemann Concaves with no issues.

Thanks for all of the replies. It sounds like I shouldn't worry too much about the rims not having a "hook".
There were a couple of recommendations for "Conti Sport". I assuming this means "Continental" but there are several models which include the word "sport". Can you please be more specific?

Running 700 x 25 Michelin Dynamic Classics on my concaves. Use 90 psi rear, 80 psi front on my Stella with no problems. They look good, ride is OK, and they're inexpensive compared to many others. Don

I would second nlerner's advice about using wire-bead tires on non-beaded rims. Steel will stretch less than Kevlar. I think that's more important than the pressure.

I have them on my Batavus and I've been running them with 28mm Schwalbe delta cruisers and now 37mm Schwalbe Marathon GT Tour tires. All of them non-folders but absolutely no issues.

I’ve got Paselas on my concave shod Paramount. Been putting many miles on them this summmer. Pump to 90 with no problems.

If you want to spend a bit more, it'd be hard to go wrong with Paselas. It's clear from the other posters' actual experience that they play nice with concave rims.

I guess I was thinking of the entry level Ultra Sport. Comes in 700x32, and it's cheap. Next up is the Ultra Sport. Max size 700x28. I think the Grand Sport is in between. Also comes in 32c. There's also Gatorskins. Continental tire line is confusing, it's true. FWIW I haven't used these personally with concave rims, which I have not owned in decades.

Back in the day, those were sold to me as the rim that would hold my weight for touring. Several times on long downhills, the heat from braking caused blow outs.

Nice sturdy rims, and like several member mentioned before, very popular with touring riders for that reason.
You'll need to be extra careful when mounting whatever tires, though, as they seem to be more susceptible to small mistakes than other rims. I had a wire-beaded Pasela blow off a wheel of my tandem because of a rim strip that wasn't perfectly centered, and apparently frustrated the correct seating of the wire bead. I hadn't noticed when I checked - as I always do before applying full pressure. I re-centered the rim strip and since then I've had no problems.

I'll second the Paselas on those concave rims. I have them on my Motobecane Grand Touring, never a problem. I also have some ultra-cheap Kendas on a Super Mirage errand schlepper with those rims, that have been fine.
