Curious what true 43mm-46mm 650b tire options are currently available. I'm using Velocity Atlas rims, so 'true' meaning they'll measure that on those rims. I setup my Riv Redwood (glad I kept) as 650b for a while now and am running 48mm Pari Motos (slightly undersized). They're mighty close to the chainstays, so looking for something slightly smaller. Asking for 43mm as it seems many of the current 42mm are undersized. 
Thanks!

Not sure I've seen anything marked between 42-584 and 48-584.

sorry i never measured what mine come out to on a set of VO voyager rims. 

I use these on my 'commuter' (i'm freelance so i don't often commute) but have and ride around NYC with these.

If you are into knobby tires, I am currently riding some bruce gordon 43mm rock n roads on my bleriot. I love mine. They rip on trail paths and didnt feel slowed down on pavement. They do make that nice treaded hum on pavement if youre into that sort of thing.

Those T-Servs are great tires, more durable gravelkings, and I didn't know they came in 650b. Those might become my new commuter tire!

I ride 700c, but agree that Bruce Gordon R&R are excellent tires! Fantastic on the rough stuff, and good on pavement. The owners are great people, too, providing excellent customer support.
I am a big fan of Panaracer tires, having ridden various iterations for years. My current favorite for city riding is the Pasella Protite. Very comfy tires, with better puncture resistance than the original. They offer great grip on pavement - and they do surprisingly well on dirt. However, I wish they came in a 700cx40 or 42. The fattest is a 38mm.

I'll put in a plug for the Soma Cazaderos. The 48 version runs small and would be a great choice if you're looking for a semi knobbed tire below 48mm.

I like the 47mm Teravail Rampart tires.

There certainly isn't much out there. I ordered 650Bx43 Gravel King SK's from Germany and they measure quite true to size and are great all-rounder tires in my opinion. The shipping is costly, but the tires themselves were cheap; I ordered two pair and the total was cheaper than US MSRP for GK's. I ordered thru bike-components.de.  They also have the nice Schwalbe tubes

Easy answer; Simworks Homage 650/27.5 x 43 (or 55). Both fantastic and on sale now for just $54.00.

Challenge makes the Strada Bianca and the Gravel Grinder in a labeled 46mm. Unsure how they actually measure, though I'm hoping to give the Strada Biancas a go soon.

I think Pirelli has a couple gravel-focused options in this range as well.

Challenge makes some nice 46mm tires.  The Strada Biancas are pretty light and supple.

I've been running the Challenge Strada Bianca 46mm tires set up tubeless since January (about 2,000 miles) on road and gravel and they've been great. Really supple and surprisingly tough. Highly recommend.

Thanks for all the suggestions. I have Challenge Gravel Grinders on the way - will report back with an actual width. Side mini-knobs might be an issue, so fingers-crossed they're slightly undersized.

Mounted the Challenge Gravel Grinders and they're more than a little undersized. I'm measuring 42mm on Velocity Atlas rims. Clearance is much improved though, so going to give these a go.
