We camp on the beach at times and I would like some opinions on airing down the tires on my TV and Trailer. I have been going to about 20Lbs and usually that's ok. Sometimes I begin to get stuck ...
I depends a lot on the type and size of the tire and wheel - the LT suffix floatation tires (not to be confused with LT prefix tires) - are more stable at lower pressures than other designs and sizes. At any rate, we always carry a high pressure portable air tank that has enough volume to pop a tire back on, and 12 v compressor to refill the tank if necessary. Never had to use it yet, but it gives us a few more options in pinch.
