I have a 30yo 2-ton Sears floor jack at home. It's a good one that they
would probably rate higher today. The problem is that the wheels are SO
noisy while moving it. I was thinking of painting the wheels with
"Rhino Liner" type urethane material.

How many PSI do those wheels see under load? The contact patch is very
small on floor jack wheels so you're probably looking at ~1,000 PSI. Can
the proposed material stand up to those loads?
