Spare tire pressure

[Skipg]

The four tires on my travel trailer specify 80 pounds each tire the spare tire only is rated for 65 pounds is this correct?

I'd make the dealer solve the problem and let them deal with getting reimbursed from the manufacturer.

SOP with me.

After every trip I crawl underneath with a mechanics mirror and flashlight, looking for anything amiss (stick or branch wedged up somewhere, chunk of mud, loose nuts, wear spot on wiring or piping, etc. Check pressure while under there. A cheap Walmart yoga mat saves your clothes and back from the inevitable thorns and sharp rocks on the ground.

I also do not wait until the day of departure from a campsite to check underneath. I check it the first morning there. Then I have several days to fix any problem rather than have my itinerary delayed from a problem discovered on day of departure.

As mentioned it is easy to overlook the spare tire. This way I will be warned if either spare is low on pressure.

Ok??
Relevance to rating on spare tire vs other tires on the vehicle?

My trailer and TV have TPMS. I added a TPMS sensor on the trailer spare and the TV spare.

Is there a reason you don’t answer questions that providing the information for would help you better understand what your actual needs are? Especially considering your first post was asking for help understanding what your actual needs are?

There are vehicles that don’t come with the same spare tire as the ones on the ground. For various reasons of course. Not saying this is the case for sure in your case. But since you don’t provide any specific info asked (asked to help you answer your initial question of course), I can reasonably surmise based on what little info you provided that it’s a TT. And it’s a 15” wheel. And the gvw of your TT is probably 10-11klbs or less and that a D rated 15” ST tire would likely be of sufficient capacity based on the numbers. (Numbers which would not require supposition but if not for ^)

Sounds like an Amish craftsman goofed up.......

I had a Class C with dual rear tires, so I had 6 TST senders. When I sold my Class C and got a dual axle TT, I had 2 senders left over, so I put one on the TT spare and one on the TV spare. I always know if either spare needs air.

Good Point ! I do this once a month during tow season..... I learned the HARD way.. had a flat and put a spare on that was under inflated...

RV dealers and even car/truck dealers have cannibalized one units tires/wheels or just a spare to get a current owner on the road or a make the sale.
Noting was said about the trailer axle ratings or its gvwr so no telling what the actual OEM tire story was for the OP unit.

How heavy is the trailer?

[bgum]

Clearly it wasn't their first report. I wonder how many they will get away with.

[ford_truck_guy]

Have them put that in writing... Never take the word from a phone call...... Just sayin
