Just met an RV owner who was told by a Discount Tire salesperson that it was too dangerous for anyone to add air to a tire that was on the coach, as the risk was too great. Apparently, from the rim or the tire exploding. Even they weren't allowed to add air unless the tire was in a cage.
Having to take the vehicle to a service center every time one needs air sure won't promote maintaining proper inflation. Is it ok for the owner to check and maintain proper pressure, regardless of the tire size?
Yes, Leigh, you can add air to your, passenger car, boat trailer, light truck, Class A, B or C Motorhome or RV trailer or dolly. It is even OK for you to add air to your wheelbarrow tire or lawnmower tires. :-)Now having said that, there are a few times when the use of a cage is advised
1. I would consider the use of a safety cage as MANDATORY for initial inflation if covered by OSHA Regulations i.e tires larger than "LT" or tires on multi piece rims
2. You should also use a cage when re-inflating any tire that had been run flat or suffered a puncture and lost more than 20% of its air.
+++++++++++++++++++I do mention the use of a cage in this post.
I have contacted Discount tire but have not heard back yet. I believe the salesperson has some of their training information mixed up as I know of no regulation or even suggestion that simply adding a few psi to a tire that is already mounted and almost fully inflated needs to be done in a safety cage.
For those not sure what an Inflation Cage looks like or what it does here is a short video from Ken-Tool doing an OSHA test.
One final comment. I did once receive a passenger tire for inspection that had exploded after being repaired. In this case the tech had damaged the tire when dismounting it. This is why I suggest that a safety cage or at least some type of restraint be used when re-inflating from 0 psi after a repair.
