Long ago my customers and I found a way we thought that was pretty accurate to verify the then current 9r and 10r22.5 tires in the OREDS and the Michelin pilots on the unihomes tire pressure, would be interesting to see if the newer tires design would still show what the old tires did.
You all might laugh and the new tires more modern design might not show this but who knows.
I used to run coaches through a water puddle then immediately on to dry fresh concrete.
As we rolled forward the tire water marks would slowly dry out..
If you were seemingly overinflated the edges of the tire tracks would lighten earlier than the center. Opposite if under.
A slight arc in the path would prevent the rears covering the fronts.
As tire pressures were a constant discussion because of over inflation issues I did this test many, many times sometimes more than once a day.
Everyone was amazed as changing the tire pressure five pounds or less altered the water pattern.
No idea if this will show on these much better tire tech but it seemed to work long ago and gave a real test to back up the percentage of load/percentage of sidewall max load we used then to figure the correct pressures.
The current Michelin charts have a sliding scale in the load versus pressure chart. Not a straight line.
Be interesting to see if anyone can see if this still works.
Or laugh at this. Seemed to work well long ago.
