I don't think you quite understand. The Char 2C you posted does have a functioning suspension, and the plates covering it up in your picture are hinged skirts. As the tank sinks into soft ground, they can lift out of the way. Further, they appear to have several inches of clearance above the track pads - you probably have half a foot of clearance before the skirts even hit anything, at which point they can move out of the way and the suspension can travel further. You can see the hinged removable skirt armor in this picture:
The Leman Russ side armor is a single rigid armor plate extending down to the very tops of the tracks. The tank would have a couple inches of travel, total, beyond which the rigid hull of the tank is literally digging into the ground and the road wheels can't/won't travel any further. It's closer to the Mk IV from WWI, where the armor extended down to the tops of the tracks and there was no suspension at all.
I know the model doesn't show it, but it's possible that the metal could deform in some way while still protecting the tracks. Rather than hinges there could be slats of armour on sliders that move up and down to protect the wheels and only expose the tracks, or even something more exotic like liquid metal. The tracks would need to overlap the edges of the armour just to ensure that only the tracks made contact with the ground though.
That's the way I think about a lot of 40K stuff anyway - when you have anti-grav, having a tank with armour that can deform to protect it's mechanical parts isn't so far fetched.

What kind of pressure would the foot put into the ground? Small surface area and all that.
Top-heavy is one thing, but sinking into soft ground would be just as bad.

Thats actually the only real problem with it is that its feet are too small. Make a little bigger and it wouldn't be too bad.

Some calcs I did a few years ago on the issue of titan footprint size requirements
Typical bearing pressures for Earth terrain range from about 100kn/sq.m for soft silt up to about 600kN/sq.m for solid bedrock.
So for a 400 metric ton titan required foot sizes range from about 7x7m to 3x3m. This is about the mass of a fully laden heavy lift 747, so probably a reasonable guess for a knight or maybe a warhound at about 50m high.
For a 160 thousand metric tonne titan you would need 125x125m down to about 55x55m sized feet if it only ever tiptoed on granite. However, this is equivalent to the weight of a 240m tall, or 60 storey building with 50m to a side, so probably a bit unwieldy, even for a giant stompy robot. It would also need each foot to have a larger surface area than itself, but I'm sure it could be finessed.
So smaller titans would be easy while the larger titans would likely need some technosorcery assistance, which also has precedence in the fluff anyway.

Of course we don't know the weight of ceramite. As its a ceramic compound it could easily be much lighter than similar materials today, providing more protection while being much lighter.

Why do you think it comes with a large oval platform? It doesn't walk into battle, it surfs in on it's "base".

Greebo had spent an irritating two minutes in that box. Technically, a cat locked in a box may be alive or it may be dead. You never know until you look. In fact, the mere act of opening the box will determine the state of the cat, although in this case there were three determinate states the cat could be in: these being Alive, Dead, and Bloody Furious.

The Exorcist has always been a bit of a head-scratcher to me, that pipe organ design is ridiculous as it is impractical.... Rule wise - How do you draw Line of Sight to your target down any of those barrels, as it lacks an ignore Line of Sight rule to my knowledge? Fluff wise - Does it mention anything about these missiles being guided, to account for why they are being shot into the air like that? Or do they just pray to the Emperor that the missiles they fire straight up will not rain down right on their own heads? Then again... it is described to be more of a rolling shrine than a weapon system, so maybe I am over thinking it.

The missiles fire in ballistic arcs, and yes, they are guided.

At least there is that! Had to ask as it was noted somewhere that the technology behind these weapon systems has been lost. Coupled with a strong dedication to faith, something common in every culture within this universe, the idea of simply praying to hit your enemy could not be removed as a possibility. The idea that the crew, more so being sisters who seem even more fanatical, leaving the weapons to 'the Emperor's Guidance' I find to be a humorous thought. However, with the shear number of missiles fired and the description of the weapon systems I stumbled over, it really did sound like an 'area saturation' type weapon instead of a guided strike. Now if the Rules gave it some sort of Line of Sight ignoring ability to represent the ballistic arc and to solve the 'aim down the barrel' problem with the pipe organ design.

You don't aim down the barrel, but... yes. I actually hate the organ version and only use the FW type, personally.

A 747-400 has its weight distributed over only about 40 square meters; and it really doesn't need that much to disperse its weight(it is more about braking power). The 747-400 has 18 tyres about a half meter by a third meter in contact with the ground at any given point and a take-off weight nearing 400 metric tonnes. The ground contact on the plane has far less to do with weight disbursement as it does breaking power(you need greater contact to stop a heavy object moving at near-lift speeds than you do a stationary or walking object).
Your math is for a single-contact object, but as you increase the points of contact and spread the distribution you lower the necessary contact.
Doubling the points of contact(as with a walker) about quarters the needed contact. Walking is a controlled fall, unless the walker in question is trying to stand on 1 foot the time between strides should be fine at a minimum coverage on all terrains other than really wet mud. Then when you get to the scale of titans the really wet mud would have to be 3 meters or so deep to even slow the walker considerably.
If we put an intelligence behind the balance and motives of a titan with any sort of neural feedback system(the princeps) then all titans are pretty well fine(their foot-falls will crack and shatter most surfaces but they will not sink in even when standing still.

The angle which gives maximum range on a ballistic arc, however, is 45 degrees, not ~90 So really all it needs to be able to do is move from 1 to 45 degrees, not up to 90 (since 46 to 90 gives the same outcomes as 0 to 45 does, yay symmetry  )
