This is our upcoming 4th season traveling to Texas for the winter.
Our 5th wheel is parked for the summer in our drive way and used for visiting guests as they typically come in 4-8 family members at a time.
In late Sept I sanitized the fresh water tank, drain all the low points, use 45 PSI to blow the lines out, and add pink stuff in the traps and black water tank in order to make it through 2 cold states whilst traveling to Mustang Island, Port Aransas Texas for the winter.
Just finished up greasing the Morryde wet bolts, removing tires and inspecting bearings, greasing bearings, and checking tire inflation. The day before we leave I put about 30 gallons of water into the fresh water tank since we wont have water in Wyoming the first night, and possibly Colorado springs the second night.
Every year during April through Oct, all (4) Westlake 16" 110 PSI tires go from 105 psi(what I run them at) to 90 psi, consistently. Is it normal for tires to lose tire pressure over a 7 month span?
Great picture!
No, it’s not normal to have all the tires drop pressure like that over that time span in my experience, my Sailuns that I run at 100 PSI haven’t needed air in over a year, they do fluctuate a bit with varying cold temps but no bleed down like you are seeing.
It hasn’t been cold enough here SE PA yet to need winterizing, close but not yet and we too are heading South to TX shortly, our trip is only unit mid December so I will be draining, blowing out and adding the pink stuff on the way home.
I winterized last week but will dewinterize in Dec for a two week vacation to somewhere Alabama this year.
We typically dont worry about travel accross frozen states as there is enough heat inside during the transport and the hot water heater is hot from the whole nights use.
We travel with 100 gal fresh water tank and will usually fill it pretty full.
the next planned trip probably full so we have water on the return leg from home,
I disagree. It would be perfectly normal for the tires to lose 10% or so air pressure over a 7 month period. Especially when going from summer to cooler weather. Every fall I need to add anywhere from 4-7 pounds in each tire on the wife’s Expedition and my Denali PU.
Question is, what are the tire temps when filled, and what are they when the PSI is down? The tires on my F-450 can gain and lose almost 10 PSI from sitting in a cold garage to the end of a 60 mile trip. They all lost over 5 PSI from when they were topped off on a 70* day to when temps dropped to 30-40*. My TST is always alarming in the morning.
Adding: The higher the tire pressures, the more they do tend to fluctuate. You normally wont see such a great variance in tires that rate 50 PSI or lower, but you will with tires rated over 100 PSI.
^^ That's a good point.
Temp when last inflated to 105 psi was 78 deg in Texas in April. Then we came home, took another short trip to WA state and then the RV sat until I checked the tires, temp then was 50 deg. We had temps between 25 and 105 here in MT from April to Sep.
