GKSK 700x38c measure 41.44 mm wide on American Classic 29" RACE wheels with 24 mm inside width rims.
I'd be interested in knowing the width of the 43's as well.

That's sweet, thanks guys!
If you have the time could you please measure the height? From the top of rim bead to the top of the knobs, you can eyeball it with a caliper.
I'm trying to squeeze in the absolute biggest tyres I can in my frame and fork, I would rather not buy tyres that don't fit... This way I can at least do some measurements first, that helps a lot.

Non omnino gravis
It's going to vary a fair amount depending on your rim width. I have a 700x43 for the front and a 700x38 for the rear on my CX, as I have only 43mm of clearance between the chainstays. On 16mm internal wheels, the front measures 40.25mm, and the rear measures 37.60mm. The front is about 1mm shorter vertically, roughly 38mm tall compared to ~39mm in the back. These tires are new, having been mounted about a week, but have not been ridden. I expect them to swell out a bit as they break in. For comparison, the 700x35 Hutchinson Overides on the bike right now measured exactly 33.5mm wide when mounted, and after a few hundred miles are now sitting spot on 35mm wide.

That should be spot on for my clearances, i'm pretty sure i'm gonna be able to fit 38s in the back and 43s in the front. It will be amazing, thank you all for your help!
Why do you think the 38s are taller than the 43s? I thought it was the other way around. If the 43s are less tall I could fit them in the back too because there the main limiting thing is the height of the seatstay and chainstay bridges.

The Stan's/Panaracer professional team gets most of their tires from Bicycle Exchange here in Wichita Kansas.
It's my understanding that the new 43mm is just rebrand of the 40mm tire to reflect the actual size of the tire.
I'm actually not sure about the new 38mm tire but, I think the new tire reflects the actual branded size of the tire.

If you check out the previous replies in the thread the 38s measure 37.60mm on 16mm ID rims, and 41.44 mm on 24m ID rims.
I think the avereage "all road/gravel etc" rim is around 19-20mm, so the 38s should measure around 39-40mm on a rim like that.
Based on reviews the 35s measure more like 37-38mm, and Panaracer didn't change the 35s.
So the 38s should be slightly bigger, and based on the specifications they're a tad heavier too.

FYI - I just heard from someone on the Panaracer Team.
The 43 mm is a rebrand of the 40 mm and should measure true to size.
The new 38 mm measures 40 mm wide on Stan's wheels.

thread derail- I found that my frame barely fits a 38mm G-One. add a little mud and it's a no-go. so I need a "true" 35mm tire, no more. the G-One measures 38mm on a 19mm rim. how likely is it that a 35mm Gravelking SK would be small enough on that rim?

I just installed some 43s on 23.5 internal rims. They measure 43mm wide and 40mm tall. Height is eyeball with caliper so not as accurate as width. These were measured with tubes and at the max 60psi. No, I don't plan to run them like that

The only way to measure tire height in any meaningful way is to measure the total diameter of the tire and rim combination.
Rims have different heights and measuring from the end of the rim sidewall isn't going to yield any kind of meaningful number for anyone who isn't using that exact model rim.

33 mm LAS vs. 32/35 GravelKing
I'm riding some 33 mm Clement LASs on a cross commuter with fenders. I'd like to run as wide of a tire as possible, without rub of course. The LASs just barely fit.
I'm thinking I should go for the 32mm GKs, as the 35 is going to be too big to fit. They'll be on 2009 Neuvation alloy road rims, not positive about the width, but at that age, I'm sure they are from well before the wider rim popularity.
Any help on this one?

Meanwhile I got my 38 and 43 GravelKings a while ago. Running them tubeless, at around 2-2.5 bar the 38s measure 39.5mm and the 43s measure 42.5mm on my 20mm ID rims. If I pump them up to 3.5-4 bar (which I never ever do, only for testing) they gain a little, about a mm.
Interestingly the bigger tubeless SKs were soooo much easier to put on compared to the tubed 32s on the same rim. The 32s took ages to put on, I had to use tyre levers (pinched one tube) but the bigger tubeless version went on super easily by hand.
They hold air perfectly fine with 2 layers of Stans tape and Stans sealant on my Hunt rims tho. I used a compressor with the valve cores removed, haven't tried a handpump.
First time tubeless, I don't know if it's the tyres, the slightly bigger size, running tubeless or all of them combined but they feel sooooo great compared to my tubed 37mm Vittoria Voyager Hypers. When I ran low pressures in my Vittorias they felt super squishy in a bad way. On harder surfaces it felt like when I turned the handlebars there was a delay when the bike actually responded. But with the GravelKings when I run the same low pressures even on asphhalt they feel great and roll so nicely, and of course they're really good on dirt roads.

Good info on the tube size! And yeah, probably a good theory on tube size actually not mattering. If so, I'm just going to go with 18/25s in 60 mm and forget about tracking down and/or paying the extra for the bigger tubes. So frustrating when you need tubes for deep rims and you realize all you have, for some dumb reason are 36s or even 32s. I measure some horrible Kenda tubes I had in my parts bin last night. The fkcuers were 30 mm long!
I've had a rough few days, which is how is seems to happen. Numerous punctures, ripped of valves, ripped a valve off with a "helpful" bike station the city put up on the MUP (hose is, NOT KIDDING, like 1.5' long, makes using it horrible).
I measured my Continental Speed Ride 700x42s at 37.8 this morning. I measured by Clement LAS 700x33 at 32.9. I've been using the Clements to commute 5-6 days a week to my office on a cross bike with fenders, rack, panniers. The rear punctured last week, one of those where the tube is flat before you can touch the brakes. Tire was paper thin. They ride wonderfully, but I think loaded commuting on asphalt is not what they're meant to do. Or, I know it. I don't want to have to worry about flats at 8:00 in the morning. I only got 6 months out of the tire, don't think I've even done that to my CX race tires that I race/train on.
As awesome as the GravelKings sound, and even with the claims of durability and anti-puncture, I think I just need to accept that I'm commuting and ride dedicated commuter tires that will be heavier, but last longer, offer better protection, and be a good deal less expensive. Leaning towards something like the Continental Travel Contact, folding, in 37 mm, as I've read they too are more around 34/33 in real life.
Great info in this thread! Gotta say I'm also impressed with the lack of bickering and the solid numbers of tire size

Older thread.
Have had some 700x38mm SKs in limited green/brown on a bike for a few years now. Just replaced with some 38 mm black/brown SKs...and I swear they're considerably narrower. I know, I know...without measurements, this is bs. I'll measure tonight with some Verniers, but wanted to ask.
This is my commuter, so I'm on it 5-6 days a week, so have a pretty good eye on what the tires look like. These 38s seem much more narrow. Anyone else experience this?

If you read through the thread, they rebranded their sizes because the tires were considerably bigger than advertised. So your new tires are probably smaller, and closer to actual size. Maybe they are the old 35mm?

Hmm, interesting. I did measure them, they're closer to 37 mm than 38. Not sure if I have older ones or what. Phew, covid supply issues are killing me. Used to stock up on these when I found them around $30 USD, now they're $50 or more. I miss the good ol' days
