In many, many years of owning and traveling in our Mandalay, I have never “…topped off…” my air when on the road. In fact, I haven’t put any air in my tires for years. I use a TPMS and I know what my tire pressures are at all times. The tires don’t leak and the pressures are stable.
Some people are lucky that way. Some not so much
When I first installed a 10 wheel TPMS system on my motor home and towed I headed North for an event.. about 2/3 the way there BEEP BEEP BEEP BEEP low tire. Left front on the towed.
Aired it up and completed the trip
Aired it up every day during the event
Aired it up on the way home Sunday
Aired it up Monday Morning
Went to Belle Tire (Where I got the tire) and found I'd been Screwed
They removed the screw and put in a proper patch
No charge (Road hazard warranty)
Another customer of Pressure Pro did not install his right away
Same tire (left front on towed) Shredded, Rim totaled, Fender over 2000 in body damage.
Some folks are not that lucky
Parked for a while in georgia due to a bit of bad luck (Blown engine) A motor home worth about half a million pulled in (NICE rig) he was late because he did not have a 10 wheel TPMS and the tire on his towed popped.. He did not appear to have secondary damage but the tire and rim were toast (He had to put the spare on which is what delayed him) I told him about the pressure pro system.
And bought one of his CD's.
