My apologies, since the o.p. was talking about using tw wheels I thought he might like to see the ridiculous wheel on my buddies.

Sorry for the delay but we are digging out. No power or Water but we got at least a cell tower last night.
Below is my TWW, which is a Yamaha TW200 that I converted the front end on. It now has a wide wheel at both ends compliments of a triple crown from the front of a Yamaha 3 wheeler:
This is much different than the BW200 or BW350 that the knobby wheel in the mockup picture came from. I have all 3 of those Yamaha models and love them because they feel like big mini trails, or mini trails when I was something of a mini. Putting one of those wheels would not be feasible if you wanted to ride it. Especially the BE wheels, they would look huge on a 500cv MXer.
For the discussion, this is what I would like to achieve, size wise, but with added suspension:
But truly the closest thing to reality, as a starting point for overkill, on a Ct restomod, that you could actually ride, enjoy and rely on, is the Black French Dax with knobbies in post #4. It was discussed on planet minis several years ago. Faatcat was involved in that post, maybe he can shed some input?

Can't recall the exact details but, yes, tapatalk runs with scissors and is incompatible with current technology. Translation...it doesn't work here.
As for fitting steamroller tires on a CT/Dax, far easier up front. Fork length & width can be altered easily enough, for a price. It's the rear that presents the biggest hurdles...shock mount width & chain clearance. If one is willing & able to re-engineer the upper shock mounts, plus a jackshaft to offset the chain drive, then it'd be a matter of choosing swingarm & wheel assembly width & height.
Haven't gone through the G`Craft catalog in a few months now however, they did list swingarm kits up to 5.5" wide. Dunno if they still offer the requisite jackshaft kits as well. There's still the significant issue of upper shock mount width to be addressed. Angling the shocks inward, at the top, is a very bad idea imho, virtually guaranteed to result in bending the upper mount.
IMHO, that suspensionless bike, shown in #23 above, had better have very soft, compliant, tires...which would really hurt tracking. Otherwise, the shock loads generated would result in frame damage.

Okay, I'm gonna bring this one back form the dead again. Quarantine had me doing all kinds of undesirable stuff, like cleaning the garage and attic.
I found enough reasonable parts to assemble most of a CT.
Meanwhile, a buddy was getting ready to spray his project with Candy Emerald Green.
Being that Candy Emerald Green is one of the greatest vehicle colors from Hot Wheels to Aston Martin, I sent my frame and parts along to his paint booth.
My problem now still exist that I need to determine the size, type, nomenclature or identity of the wheels on this awesome French DAX:
Any help is appreciated. Don't know who's it was.
Saw it on planet minis years ago and saved the picture.
I know Faaat Caaat had some knowledge of this bike (way back in the day).
I sent the question to Trail buddy twice, but never found an answer.
Help me ID these rims, wheels, tires; I'll find a way to make them work.

G`Craft Dax rims are (were?) available in different widths, ranging from the stock 2.50/2.75" (depending on the source consulted) up to 4.0", at one time. Be forewarned, I've not checked in a long time now. Other outfits offer different widths...Kitaco, Takegawa, Daytona, et al; the list of players and options varies over time. There's also not a whole lotta cubic real estate to work with on these bikes. 120 section width tires are the limit beyond which keeping the wheel centered becomes an issue. 130 section width out back requires offset sprockets and will not fit up front with a disc brake. Then, there's tire diameter to consider. Beyond 19" diameter, you start losing chain adjustment range, 21" takes nearly all of it, then there's tire-to-fender clearance to consider. Tire-to-fender (or frame) contact out back would result in tire damage; up-front, it'd put the rider over the handlebars...and I've seen the results of both, it ain't pretty. This is why we rarely see tires bigger than 120/90-10 on these bikes...this includes 12-inchers - same amount of clearance so they have shorter sidewalls to make up the difference. It is possible to go with longer, aftermarket, fork legs; extended swingarms and longer shocks can be sourced. Up front, you can get close to 2" taller than stock; out back, you're limited to more like 1" taller than stock. Shocks much longer than 350mm will result in chain clearance/angulation problems. It is possible to fab wider fork trees, custom axles & spacers. That's also possible with swingarms. There are even some wide rear wheel kits available. This can get quite involved but, with time, talent, motivation...and enough bucks...it's all possible.
The black bike, pictured above, looks like it's wearing 140 section-width tires...intended for industrial equipment, like a tiller or snow thrower. They may be terrific in dirt and snow, on pavement not so much. The CTO "bobber" might be rideable...with reasonable length shocks swapped-in, and road equipment, like lighting. I see what appears to be maybe 2" of rear tire clearance. The point of these ramblings is best described as "fitness for purpose". IOW what looks good in photos may not be any fun to ride...or safe...or even viable. Some of the wildest custom builds I've seen have clearly been built for show only...and those are very cool, too. The workmanship & creativity has been state-of-the-art. "Fitness for purpose" includes visually stunning, show-only, machinery too. Touring Route 66 and touring a show circuit are two examples of very different purposes...with vastly different requirements.

I think maybe they ARE 10"
When you look at the proportions of the rim, and consider the stock hub...I'm thinking 10"
That helps to make the huge tire, look huge.

Totally Agree 10 inch, but maybe wider than stock?
(I've used up all the 10 inch stock rims on our 50s)
They were sold in the UK, as well, and in recent years. Might be able to find some info from there, and it'd be in English, no translation required.

ZODC,
The VanVan is what I used as a wheel donor on my TW-200 conversion in post # 23 above.
I saw them when I lived in Japan in the early 90s, but I've never been a Suzuki guy.
I ended up getting a VanVan rim from a Suzuki dealer in Hamburg Germany on a layover, and laced that up to a stock Yamaha TW hub.
FWIW,
I've just ordered powder to powder-coat my CT-70 frame and parts.
Not sure which direction I'm going yet; I'm leaning towards trying 130/90ish tires on stock 10s.
I'm trying reduce the parts pile and at least make something useful.
I don't have the parts to make this a show quality restoration and I don't want something else in the garage that doesn't get used or ridden.
My goal is not "Frankenstein" but more like something the Honda design guys would dream up for a motorcycle trade show.

I will tell you definitively that 130/90 tires will not work...they will clear your swingarm but will not clear your chain...it will rub the tire.

so it's not going to be a quick build,
and it's definitely not going to be the overkill I was dreaming about,
But we have a starting point:
Went with Prismatic Powder's illusion Apple Sugar 2 part powder coat.
Decals are on the way.
As soon as I can find a set of 10 inch wheels and hubs we'll have a roller.
