I have a new front turf tire on a new mower that goes from 18 psi to 10 psi in 48 hours. Have put ten hours on the machine hoping it would seat and seal, suspecting the leak is between the tire and rim. No dice. My dealer is over 300 miles away. Re seat it with tire lube? Take it to the tire shop? Slime it? Tube it? The leak is so slow, not sure I would find it in a dunk tank. Any suggestions? Not a big deal, just a little annoying.
