Air in the Spare

Just a reminder for folks to check the air pressure in the trailer spare tire more often than "once in a while"

I had GS come today to change a tire for me,the air pressure required is 110 psi.My spare was only at 62 psi.Not good!
GS did not have a compressor with him.Fortunately I had mine.
My spare is tucked up under the traler (difficult to get to)
I plan on getting an extention line of some sort and run it out to a built in guage and valve stem,so I won't be caught like that again.
Any thoughts or ideas where to get the needed items?

  • Yup,
    I always check all the tires on truck and trailer regularly.

    Being you have a Dodge in sig line... Geno's Garage has or maybe used to have what they called something like "extend a spare" air line or words to that effect. I've had mine 5 or more years. It threads onto your spare tire valve and has about a 3 or 3 foot hose that you can zip tie up or mount how you want and check air pressure at end of hose line and not underneath laying on your back. I never mounted it because I use it on different vehicles. If I recall price was around $10 bucks. Works great for my use. It looked just like this http://www.sportys.com/ToolShop/product/12409 I don't know if this one is good quality or not.

    Thanks,I'll check that out.pretty much what I had in mind.
  • I rarely check mine since I always have my 12 volt with me. I can fill it up once when I need to use it or fill it multiple times when I don't need it. Not lazy but that's my story and I'm sticking to it lol.
  • Yep, that's why I carry a cheap 12v compressor in my truck. I don't need 110 psi, but I do need around 50 psi when towing, so if I am caught short on PSI, it only costs me a little bit of time... ;)

    I do check my spares on the truck and the trailer at the start of the season, and top off, but have only found them to be about 5 psi off of max, so not really a big deal for me...

    Still, very good advice, as you should always know what condition your spare is! :)
