If you look at the gear for many of the WWII and
later large aircraft, there are red marks on the tires that line up
with red marks on the wheels so the crew can see if the tire has slide
on the wheel.

We have that on all our planes here in the UK.

It's one of the things to check on the pre-flight, that the tyre hasn't
rotated on the rim, possibly damaging the valve.
