These are pinch flats, also known as snake bites. For more info, you could have a look at What are pinch flats?, Best practice for patching snakebite pinch flats on skinny tubes
and Is there anything I can do to prevent snakebites (pinch flats)?

Three steps:
is it rubbing the entire rotation? If not true your wheel.
Is it rubbing all the way round but just on one side, fix the dish of your wheel.
If it is neither of the above, you need a smaller tyre.
All tyres will expand to a point as you increase the pressure. They will expand less and less as the pressure increases up until the point that they ...

There absolutely do exist tables of tire friction coefficients; see here for an example -- but friction coefficients may not be exactly what you're looking for.
I don't know of any specific tables that measure lean angle and here's why: we do know some of the factors that affect rolling resistance. They include tire construction materials, type (tubeless, ...

Sometimes it matters and sometimes it doesn't. Some tyres are designed to be mounted in either direction, some tyres are designed to be mounted one direction only and some tyres have opposite directional arrows depending on if the tyre is on the front or the rear wheel.

Very roughly, you take the ISO size (on the side of the tire, in a form like "38-584"), add the two times the first number to the second number (eg, 76 + 584), and that gives you the wheel diameter in mm.
(There is the problem that the tire width value is far from exact, but it's about the best you can go on.)
If the application you're dealing with wants ...

Some Presta valves can accept stem extensions and the upper valve body (containing the little nut you unwind to add air) can be unthread from the lower part to accept extension. Anyway, this sometimes comes unthreaded with the use of a presta to Schrader adapter and air is lost. Perhaps this is loose and air isn't getting into tire/tube but escaping here. ...
