For the record, according to Schwalbe's FAQ, E|RTRO says you can fit
tyres up to 62mm on 21mm rims. And you can even fit them on 17 to 19mm
rims, if you do not inflate above certain limits )eg 45psi for a 60mm
tyre).

Agreed. For a noticeable suspension you need to go very low on pressure.
The front handling is very poor then.

Compared to what? A 25 mm tire at 8 bar? Perhaps.

Yep. I've used 60-559, 60-622, and 50-622 sizes extensively, and I
have some experience with the 60-406 size. For the purposes of this
discussion I'm going to limit myself to commenting on the 60-559 and
60-622 sizes, since they are the ones that really stand apart from the
usual selections in those rim diameters. I'd only use the 50mm
versions if my bike was unable to fit the 60mm ones.

Yes, in that they can attenuate shocks to a similar degree (similar to
a telescopic seatpost, anyway). But you have to run very low
pressures to get that sort of benefit from them, and how low you can
safely go depends on how wide your rims are.
I weigh about 350 lbs., and I can run these tires on relatively crappy
city streets at 2 bar, or about 29 psi. I have had no pinch flats to
date at such pressure. Rolling resistance at 29 psi is surprisingly
OK; while I'm sure it is slower than at the tires' max 65 psi rating,
I don't notice a speed difference. I only notice a difference in
cushiness and in handling/traction.
> 2. What size tyre? What size rim? What make rim?
My favorite size of the Big Apple is 60-622 or 29 x 2.35". Between
the width of the tire, the flexibility of the tire, and the diameter
of the wheel, I've found no better ride quality in the cycling world.
It bridges gaps, absorbs bumps, steps up gently onto raised edges, and
finds a secure footing on irregular surfaces like no other street
tire.
I've run the 60-622 Big Apple on three kinds of rims: Mavic T519 (an
ordinary touring bike rim), Sun Rhyno Lite 700c (a 27.5mm wide MTB
rim) and Kris Holm 29er mountain unicycle rim (a 38mm wide downhill-
style rim). Not surprisingly, it works best on the widest rim. It is
on the 38mm wide rim that I can use sub-30 psi pressures without
noticing any lateral casing deflection in hard corners. The Sun Rhyno
Lite is almost as good in that regard, but mounted on the Mavic rim
the tire is significantly less stable at high lean angles. However,
the tire's shock absorbtion seems slightly better at any given
pressure when the tire is mounted on the narrower rim.

Width? Something wide; I'm not sure it matters all that much. I
understand that there are a lot more wide stadtfiets-type rims
available in Europe than there are here in the States. Anything from
622-20 on up should be appropriate. In the USA, that pretty much
limits the choices to just the Sun Rhyno Lite 700c and the Kris Holm
29er.
For 26" rims, the choices get a lot more accommodating. Sun Metal
alone offers the Rhyno Lite, Rhyno Lite XL, Mammoth, King Pin, Double
Wide, Single Wide, Double Track, and probably others that are all
559-21 or wider. There is a bewildering proliferation of wide rims
intended for downhill and jumping MTBs, but many of these have no
brake tracks and must be used with hub brakes. For best ride quality,
I would not bother with any rim wider than about 559-35.

For good handling, ride quality, and traction at low tire pressures,
the rim width must be a good match to the tire width. When the inside
width of the rim is about half of the tire's inflated width, the tire
should be quite stable at any ridable pressure while still allowing
decent compliance over bumps. At the same time, the soft tire's
ability to conform to the contours of the ground surface provides
additional traction.
I have a mountain bike fitted with 26 x 3.0 siped slicks mounted on
45mm wide rims. Despite my approximately 350 pound weight, I can run
these tires at 16-18 psi for a very soft ride. At the same pressures,
the traction this bike offers in corners is superior to that of any
other bike I have ridden. Sometimes I use higher pressures up to 40
psi to diminish rolling resistance, but there are no discernible
handling benefits from doing so.

My every day/commute bike has 2-inch (50-559) Schwalbe Marathon tires,
which are similar to the Big Apple. Although fine on unpaved roads,
there is still much more vibration/shaking compared to my mountain bike
with front suspension fork. But compared to my old commute bike with
700x28C, the wider tires are far more comfortable (and also safer, I
think), and in the city I don't worry about potholes or a tire getting
caught in tram tracks. Any difference in speed or rolling resistance is
so minor that I don't notice it.
So 25 years later I have overcome my indoctrination by Eugene Sloan's
"Complete Book of Bicycling".

Where are you riding? On trails? In fields?
On paved roads (mostly) on a bicycle that looks a lot like this:

LOL
There are many Schwalbe tires called "Marathon", but the most popular
of them are stiffer tires than the Big Apple that have more rolling
resistance when run at very low pressure. And low pressure is key to
a tire's suspension effects.

A suspension fork usually has constant-spring-rate travel of between 2
and 7 inches. Stiction (the fork's initial resistance to movement)
can be insignificant or bothersome depending on the specifics
characteristics of the fork. Bottoming a suspension fork is
uncomfortable but not usually damaging.
A tire has, in effect, sharply rising spring rate and travel that
maxes out at the height of the sidewall (in the case of the Big Apple,
about 2 inches). In fork terms, the suspension travel even less than
that-- it is the difference between the tire's sidewall height and the
height of the tire that would otherwise be used. Tires do not have
stiction, but tires with very stiff sidewalls can display a sort of
resistance to being squashed that is comparable to a small amount of
stiction. Bottoming a tire usually flats the tire and sometimes
damages the wheel.
For these reasons, the suspension action of a fat tire is more
comparable to that of a very short-travel suspension such as the
Cannondale Silk Road fork or the Moots YBB rear wishbone. And a fat
tire offers this much suspension along with the benefits of low added
weight, high reliability, increased traction, increased tire wear
life, and longer intervals between tire top-up.
