Your logic pnichols would apply to solid wheels, while pneumatic tires do flex and flex quite a bit.
Not the best pictures, but this is what I could find on the net.
Side flex can be huge. Obviously stiff truck tires, especially low profile will have it less, but still.
Bottom line, European heavy trucks drive on 4 or 5 axles just fine and tandem seems to be well more common than side duallies.
Tires can also flex a bit radius-wise, but that comes with big forces.
Don't expect such flex from truck tires.

Time to step up to the new Ford F450 Super Duty, a mere $94,000 comfortably equipped.
Should call it 'Super Stupidity' instead.
You must be talking sunroof, leather seats, upgraded radio and carpets?
My special order F350 come to $62k what include over $2 extreme towing package with 360 cameras and 2-tone tri-coat paint.
Yeah, but Sprinter is not 2.5m wide and how many 350 Sprinters sell in Europe?
Working on both continents, I observe that it is using different approach to start with.
Europeans on the average have less money to spend, so they do their homework and go with
"spend more up front and save a lot later"
US citizens go more "buy on impulse, buy cheap and worry later"
Vide all those gasers v/s diesel truck disputes.
Obviously you will find exceptions on both sides. ๐

I was thinking about the difference in dual tires between US and Europe.
In Europe tandem inline is partially forced by narrower roads and you often see double steering axles, what is unthinkable in US, but thinking about it, inline wheels on sharp turn will bend and tires can bend a lot, while US dually have 2 tires turning at different speeds against each other.
I had 3 axle equipment trailer and did not have excessive tire skidding unless I come to jack-knifing it.
Bottom line, I love to watch the movies where 4-axle trucks take 120% grades.
We use inline as well but as far as a Motorhome or Off Road no problems. Remember Sprinters and other makers Vans are side by side duallies. Inline tend to be used for extended chassis and off road applications

Big power for the era, but cheap tires and lack of electronics with rear engine did not let the power to be used very often.
They really suck in the snow.
They were at one stage taken over by PACCAR have since. sold them to an investment group. Tatra used to make their own V8 diesels for the trucks

U.S. owners might not be willing to keep replacing rear tires, often, due to tread scrubbing on hard road surfaces ... from a "bother" viewpoint ... not a "budget" viewpoint.
Tandem's tire wear is OK on soft surfaces, but not as good as side-by-side duals on hard surfaces.
No not correct.Tandem Inline are very useful Off Road, all on road Motorhomes in Europe use a Tandem inline set up
