I was just told by my LBS that both my front tire AND wheel we're on backwards. My tire (Vredestein Triforzza) has a slight diagonal sipe (but no arrow on the sidewall). My wheel's decal was upside down. I said "OK, but the wheel is symmetrical so what difference does it make?". The mechanic said the cones in the hub are designed to rotate in one ...

With some bikes the wheel is not self-centering. This is especially true on less expensive bikes with a separate derailer hanger vs one that is integrated into the frame. If you look you can see that the left and right dropouts are not symmetrical.
In such cases you must manually center the wheel when you remount it. The best way to do this is to install ...

3M duct tape, 3 layers at least (cut to fit). Alternative: 3M super 88 electrical tape. Again layers of it. These are just poor mans solution in an isolated place but with a hardware store around. If you have good LBS stores nearby, get the best recommended.

I don't think the heat will damage your tires much but there is another problem that I experienced a few times. On hot patches of asphalt (either newly placed, or just on a hot day in full sunlight) your wheels can pick up a bit of sticky asphalt. This asphalt patch in turn picks up small pieces of debris from the road and that is where the trouble starts.

If flat takes you out of the race, then there is no big reason not to do this. As noted, the biggest reason not to is having to carry more flat protection.
You might even decide to purposefully choose different tires - a bit heavier in the rear for a bit of puncture protection, something that adapts to wet a bit better in the front for steering when it ...

I don't run mixed because it doubles the gear you need to carry, spare tubes for the clincher and a spare tire for the tubular, maybe some extra sealant and hope it sticks depending on the leak.
There is not a need to get the same brand/make/tread tire as the clincher tire won't work on the tubular rim and the tubular tire wont work on the clincher rim, no ...

I would be much more worried about something like the famous Beloki crash in the TdF ten years ago.

I'm guessing from the way you worded this "pressure on a group of spokes" that there is in fact pressure on spokes when you put your CX bike in this rack. Assuming that, then yes, this rack can cause damage to the wheel. The most likely issue you would have is that the wheel would go out of true and you'd have to true it up. My bigger concern would be your ...

I'd be concerned if you you were hooking your trusty XC bike up to a public rack that looked like that, not only would it be nearly impossible to secure your frame to it but I'd fear someone would come along and indeed damage something, even unintentionally while wrestling their bike free from the same rack.
But at home? It depends on how long you plan to ...

I don't think so - I've ridden over 1/4 mile stretches of freshly poured asphalt with no apparent damage to my tires.
The asphalt is around 300 degrees F when it leaves the plant, but it will have cooled to 200 degrees or less by the time it's open to traffic (water will stand on the surface without boiling, so it's definitely below 212F)
Further, unless ...

Racing slicks are delicate depending on your brand/quality, but I wouldn't throw them up against any type of weird surface or material. When in doubt, walk it out.

Hot asphalt can be in the neighborhood of 200F, and contains some fairly volatile oils. It's probably safe to ride a few hundred feet on the stuff, but I'd avoid anything longer, especially with lightweight tires.

Could be one of a number of things.
Hub
If you grab the wheel and shake it from left to right is there noticeable play? If you hold it by the axle and spin it does it feel gravely or gritty? Does it make any noise when you do that?
Brakes
Are the brakes dragging on the rims? Is the rim buckled enough for the brakes to drag for only part of it? Is it ...
