Yup. The initial cost of buying the rims would be a little steep but then you could run real trailer tires that will last 4 times as long as the junk st tires.

I have learned about tires on the travel trailer from this thread. We just got back from a three week trip and 4200 miles. The tire pressure were consistent at about 47 lbs. I checked the pressure before we towed the trailer out of the camp site, Walmart or Pilot. I will inflate them to 50lbs. like it says on the sidewall. We did not have any trouble, but maybe we were just lucky. They are the tires that Jayco put on from the factory for the 2016 model year.

Airstream now provides E-rated 16" Michelin LT Light Truck tires on all its new 30 footers. Read in latest trailer Life I think page 6.Noticing more and more truck tires on campers in Arizona. Thanks

The factory tires seems to stand up better more North because of the outside temperature. With proper inflation and proper alignment of the axles the China tires are mostly OK (not the best). Speed and outside heat is a killer for tires. I run on Westlake tires and they do OK for me.

This spring I replaced my 2012 tires with some Carlisle HDs and upped the load rating from C to D. C-rated max inflation is 50 psi and D-rated max is 65 psi. The tire store who installed the tires was quite reluctant to inflate to 65 psi, and when I was on the phone with TST (I also bought a TPMS this summer) they also suggested that I don't inflate to max PSI. Their suggestion was to keep it in the 60 PSI range. I am not really that worried about their load carrying because we are well under that, but it sounds like a higher PSI would mean cooler tires. Who/what do I listen to?!?!

When I was looking for new tires, I called both Jayco and Dexter (axle company). Jayco said our 13" rims were rated for 65psi. Dexter rep said run max tire pressure on the tire. Discount tire said run max tire pressure. I run max tire pressure, and have not seen any tire wear issues.

I am running the same tire.

I've always ran my TT tires at Max psi. And like Jagiven, never have had an issue. Goodyear, Sailun and Carlisle recommend max psi.

When I had to replace mine because of age (one blew out) I also went up from 13 to 14" and up to load range c (1760#). A single will support the trailer and with having double axles I know I'm in decent shape. I always run just a few pounds low of max pressure just because I can - no real reason.

Check the pressure at least once a week. Monitor the pressure and temperature somehow, TPMS, good pressure gauge and a laser temperature gauge to check tire and hub temps when you stop while traveling.

A good physical inspection is also a habit that may pay off someday in a big way. A tread separation is very obvious if you know what to look for.

Any time your vehicle is worked on, check the tire pressure before leaving the dealership. They are famous for rotating tires and not adjusting the pressure.
I see folks on here mentioning using laser temperature gauge to check tire and hub temps. How do I find out what the temps should be to know if they are running hot? I don't think I have ever seen this information published in the trailer manuals.

I used to use and still carry a laser temp gauge. The temps that you read with it are subjective in that they can vary depending on many factors. I used to check all of them on the same general area and did not get concerned unless there was a 10-15 degree difference.

Now that I use a TSP TPMS, it gives me a real time readout of each tires PSI and Temp. The info from Michelin that they use as a self destruct temp is 153 degrees. That what the alarm is set for.

Many things can affect the displayed temp but the main ones are speed and low tire pressure.
On my TSPS, I monitor the individual temps and they usually track within 10-15 degrees. If I see them drift higher, I slow down and closely monitor the psi. A dragging brake shoe can also cause the temp of the tire to go up.

IMO, I would not feel safe w/o it.
