TT Tire Pressure

Things were much easier before the TST monitor ๐Ÿ™‚ Tires were up to pressure, and then they weren't!

Tire have max pressure of 60 PSI. They were at 57 when I left MI, while driving to FL got up to a max of 69. Is this acceptable while driving? Temps were just a few degrees above ambient.

One interesting point, right side tires run a touch hotter 2F over left side.

Simply not interested in an add on monitoring system. If I have a road hazard claim it will cost me $100 insurance deductible. If I have a non road hazard GY will pay for all the damages.

So I guess I will be saving money.


How much is your vacation time worth. And have you ever had to change what was left of a tire on the side of the road?


Guess you didn't read my earlier post.

I had a wheel bearing issue along CA 101 that I was fully prepared to deal with. What the HE!! did people do before all this high tech **** came along?

My thing is. I want to know when a trailer tire is flat. TMPS will tell you that. I had a flat a couple years ago. Pulled it for miles before someone told me it was flat. Yes it separated, and there was nothing left of the tire when I stopped. TMPS would have told me instantly.

1. READ YOUR VIN STICKER. IT STATES WHAT THE OEM SAYS TO INFLATE THE TIRES TO BASED ON THE WEIGHT AT MANUFACTURE.
2. Tires for a lot of people are out of sight and mind. Running 10lbs low for hundreds or thousands of miles will ruin a tire. It just won't be visible, until "IT JUST BLEW". GD Tire maker:B I get Motorhome tires and trailer tires way under the correct PSI all the time. Especially Motorhomes, up to 30 lbs low. Usually Trailers are around 15 to 20 lbs low.
3. I guess this is so, because it can be a pain to find and fill your RV tires when on the road. Doug

You can increase the pressure beyond what is on the sidewall but it does not increase load capacity beyond the rating.

When I had 50psi LRC (ST) tires, I regularly used a cold inflation of 55psi.


Maybe provide a tire manufacturers link to this please.


Read the side of your tire. It probably says something such as "max load xxxx at xx psi". Maximum load, not maximum psi.

Roger Marble of http://www.rvtiresafety.net/ has addressed this a number of times.

Here is one article he wrote that may or may not help in understanding;
http://www.rvtiresafety.net/2015/07/when-is-minimum-inflation-maximum.html

Edit;
Here is a pdf from Goodyear about the 65 mph rating of Marathon tires. It speaks of increasing the pressure 10 psi in order to operate at 66 to 75 mph. The limiting factor on increasing the psi according to Goodyear is the wheel and the stem, not the tire.

Great article, thank you!

WRT not having a monitor, I can't count the number of times I've heard "the tire suddenly blew". Well, maybe it can happen, but I'd bet a dozen doughnuts there was a problem that developed just before it suddenly blew.

Sensors are for low pressure. Inflating cold (no sun, no driving) the hand held pressure gauge is correct.

Definitely agree with quality tires, but even the best tires are not immune to a slow leak caused by a wayward nail. The TPMS can save you from a destroyed tire, or even some trailer damage caused by a destroyed tire.

Heck, repairing one of those Goodyear tires instead of replacing it would just about pay for a TPMS. ๐Ÿ™‚

Inflate cold to pressure based on your actual load. Don't worry about what the sensor tells you.

Better yet forget the sensors completely and simply buy quality tires!
