110 psi tire pressure??

[ken_burke]

All . . . . help. What tire pressure should I use on my ST235/85R16 tires by West Lake (forest river). My 5th wheel is heavy, i.e. 3000 pounds on each wheel and tongue. (15,000 pounds total). My tires are G rated and limit is 4080 pounds (actual weight is 3000). Max presser on is 110 psi. Do I have to run that high of pressure??
The problem is how to I get that pressure with a portable tire inflator? Also most tire inflators are DC hooked up with the trucks 12 volt. that won't work.

thanks . . . . ken

There should be a plate or sticker on it somewhere indicating the recommended pressure.

Also it should be spelled out in the owners manual.

All I can say is that I run 80 psi all around-5er and truck, when I am towing. My tires say max 80psi. As for the inflator, if there isn't a 12 volt one that will go to 110 psi then you might have to get a portable 110V compressor. Ok I googled a 12volt 100psi compressor and there are a few 250 psi 12 volt compressors on Amazon.com
