Gravel King SK mounted width?
I'm looking at another set of gravel tires for gravel races on some of the smoother roads around here in MI. For those not familiar with our gravel, the roads I'm thinking of for these tires are hard packed with occasional sand and not much actual gravel, haha. TBH, 23mm road tires would work on many roads but I know that somewhere in the mid 30 mm size lets one ride over the inevitable spots of washboard and such far better.
So, I'm looking at a Gravel King SK tire, but unsure how they actually mount. I've currently got 21mm internal width rims on my Warbird and in the future may be looking at 23-24mm internal rims with a more aero rim profile for these tires. With those rim widths, how should I expect a 32mm or a 35mm GK to mount up? Does anyone have experience how these end up fitting? (search doesn't find much) Are the sizes listed already taking into account wider gravel rims, or more traditional road rims? I've already got 40mm tires and am concerned that the 35mm may plump up on my rims and end up being no different than what I've already got.

The recently in the last year changed the casing size to be more true to width on wider rims. This hasnt been officially confirmed for all sizes but at least for the wider widths that is the case. So assuming you get a new casing it should be true to width. Not sure how popular the 32mm width is so it may be older stock...but I'm not sure how wide that one mounted up in the first place since so few people run them.

I have the GK SK 700X32 mounted on Cannondale 25mm internal width rims, they measure slightly under 33mm max width at 35psi.

Current production 32 was 32.2mm wide on a 23mm wide Kinlin TL-23. It was only 27.5mm tall. Have you seen this update from Panaracer? They decreased the casing length again in 2019 so imagine the bars moving down the graph a tiny amount - my 38 GK slicks were 2% shorter.

I don't like such wide rims with narrower tires. Aero isn't that important but such a wide rim on narrow tire like that is going to shorten the acceptable pressure window as it decreases the height as well as make the tire more susceptible to pinch flats (even tubeless). IMO tire/rim ratio should be 1.8-2 or greater.

the only time I would err on skinny tire on wide wheel, is on paved road. However that has draw backs too. Like landing on your heel on a slippery surface.
As for MI sand I would presume that the new 700 Byways would be a good tire choice. not sure how the center slick would be for traction and what kind of hills you have. Ohio has short punchy hills, and I have never had an issue climbing them on snow on a 25c slick though. maybe it's the way I climb?

The news release seems to only apply to the 40mm version being relabeled as a 43 though? No mention of the narrower GK's. I do wish that chart was available for all tires!
I'm not necessarily concerned about the aero impact of the width, but the future rims I have been considering are actually some of the recently developed aero gravel versions. Race pace around here is about 20mph, so I do feel that at least the combo of aero rims and tires of the appropriate width for them is useful at those speeds.

Yes, our hills tend to be of the short/punchy type, no room for long sustained climbs with the topography we have. Traction is never an issue since they are hard packed. Well, at least for any hill I would be taking these tires on. There are one or two seasonal use roads that are loose and rutted but 99% of our gravel/dirt roads here are easily driven in any 2WD family sedan when it isn't winter. I'm weary of a center slick section in the rain though. Our roads are chlorided and stay packed, but they develop a thin layer of slime on top that it seems a low knob helps break through.
Thanks!

when walking in winter, landing flat footed gives traction, landing on the edge of your shoe sole sends you sliding.
I put a pair of 23's on a wide wheel instead of the tire being bulb shaped it became D shape. or more like [ shaped. IT was the fastest tire I have ever ridden on pavement. wasn't to bad on wet roads either, until the temps dropped. and then any leaning whatsoever made traction on wet an on/off thing.
anyways some tires work others don't, the biggest thing to consider is that skinny tires on wide wheels will change the transition in cornering.

I'll throw my two cents in for a 31 or 33 Terreno Dry. Great rolling tire with just enough grip for the slimy stuff.

I run 38 GKSK tubeless on 17mm internal width and they are almost 40mm after several months. I really like them.

My 38 slicks measure 37.4 on A23s 18mm internal width.
My 35 slicks measure 34.5 on the same rim. This is after a month of being inflated up to 50psi and ridden.
Kind of annoying after I read all these reviews that they’d be larger. I was hoping for a 40 and 38 respectively. Oh well!

I was going to suggest that to OP as well. My set of 31 measure true to size.
