Recommended cold PSI and Tire Linc settings for Goodyear Endurance on 22RBE

[alias100]

Just installed Tire Linc on our new 22RBE and have it connected to the Compass Connect app on my iPhone. We have Goodyear Endurance ST205/75R14 tires (spare is a different brand, but that is another story) and the sidewall says max pressure is 65 PSI. Anyone have any good recommendations for:
What cold PSI to pump them up to? Live in Utah where daily highs normally in mid 90s. Don't expect to be loading the trailer up to it's max weight very often if ever.
What to set as Max PSI and Max Temp in Compass Connect/Tire Linc? Want to be safe, but not get alarms all the time.
Thanks for any suggestions. Heading out on our shakedown trip in a couple of weeks and want to be as ready as possible.

Your trailer tires should be inflated to the pressure stated on the weight and inflation sticker on the trailer - then set the nominal pressures in the TPMS to the same.

Thanks for the answer, but I am looking for some estimate of how much the PSI and Temps will increase while being towed on a warm day. I don't want to set the Max PSI and Temps so low I get too many alerts, or so high I don't get an alert before a blowout caused by too much heat and/or PSI.
Probably worrying too much about this.
Thanks

Start about 20% over the specified pressure for max. Since the pressure will rarely drop, I set the alarm for 5 lbs low because I want to know quickly if I'm losing air. My tires are inflated to 80 psi so I alarm at 96 and 75. My tires usually run in the low 90s for pressure once I'm on the road.

158 degrees is the default temperature alert setting on mine and I just use that.

I don't get any false alarms with those settings.

I have GY Endurance LR E. I inflate to 80 PSI and they have been running in the high 80's PSI when on the road. And I am in hot weather of Florida. I believe my alarm settings are similar to [MENTION=10506]jkwilson[/MENTION] is running.

I set my pressures to 65 cold per the sticker. My TPMS shows the tires run 69-71 on the highway on a summer day.

Thanks for all the replies. I think I have a good starting point now.
On a side note, is there any way to close a thread or disable further replies once the questions have been answered so you don't take up any one else's time?

Update from today's travels in the Southeast:

GY Endurance Load Range E
Cold PSI 80
Traveling PSI 87 & 88
Traveling Tire Temp 109 to 111
Ambient temp 93
Real Feel 106

My Goodyear Endurance tires have big letters on side of tire with pressure, in my case it's 65 psi. Told my tire engineer that you should always inflate to recommended psi for tire. Pressure will get higher when your pulling camper and tires are designed to handle this added pressure. I always check tire pressure before each trip and inflate to 65 psi if needed. One thing that I've noticed with Goodyear Endurance tires is that you hardly ever have to add air to tires just like with your tow vehicle tires.

True. We have been on the road for two months and only had to add a couple of pounds once.

I agree with that. With my previous set of Westlakes I had to add air frequently.

You can't directly I don't think. Suppose you could ask a mod? Or post up some inflammatory political material. That will get it closed. lol (Not really recommending that though)

 

[Ynot4me2]

We don't normally close threads as they might be helpful to others down the road. We will however delete any post that are inflammatory political material but just that post. [emoji2960]

Without real weigt, I cant give an advice
Yout tires maxload i got from list of Goodyear is 2040 lbs= loadindex 105 AT 65 psi upto 65mph.
So if you now only give real weights in use, I can calculate.

Normally I substract for ST 6 loadindex steps, but smaller sises like this one ST has same maxload as LT for 99mph calculated.

And I found on European sites this sise in C tire 8PR 109 R , so even higher maxload for higher speed.

But if you give the weights and configuration ( number of axles) I will calc for both tires, to see if you realy need the 65 psi.

Haven't weighed our trailer or truck, but our 22RBE is supposed to have an UVW of 5125 and a GVWR of 6995. Even the upper number is below 50% of our truck's tow rating and rounding the 497 lb tongue weight up to 1000 lbs still leaves us over 2300 lbs of payload so I don't see the need for exact weights. We thought being over-trucked was a good idea for safety and ride comfort. Does hurt at the gas station though. We don't pack that heavy so we probably won't approach 6995 very often.
This trailer has dual axles. I drive fairly slowly, particularly now with the Ram truck still in the 500 mile break in where they recommend max of 50 mph. Once through the break in period will still keep it at 70 or below.
I am curious how you are doing the calculations so any info you can share would be appreciated.
Thanks

Even when I fill in GVWR, and use the 2040 maxload a tire outcome is 56 psi.
If I first substract 6 loadindex steps , 67 psi.
But again, to my conclusions not needed , because to laws of nature the 109 loadindex of European tyres calculated for 99mph indicate , the 6 li steps where not added for the small sises ST.

Using 109 Loadindex gives 49 psi advice.

Rule of tumb for that speed/maxload- relation is.
Every 10kmph/6,3mph different , 1 loadindex-step different.
Lower speed/ higher loadindex
Higher speed / lower loadindex.
Continental groop uses this on tyres used in Europe, dometimes gives aditional service descriptions on C-tires ( LT), is other loadindex for other speedcode on sidewall.
Trucktires in Europe almist always give additional service-descriptions, and rule of tum already not working, even 2 LI steps/ 10kmpu.

In my made spreadsheet I use a formula that comes to higher pressure then the European official , i once got hold of and went running with.
And substract for Amarican TT 10% towbarload, and make remaining 90% load on axles 90 % used of loadcapacity beonging to the calculated pressure.
This together with that its calculated for a deflection needed for 99mph, gives it maximum reserve with still no bumping ( screws tremling loose, or doors open after the ride).

So higher then 56 psi you certainly dont need.

The 6 LI steps reduction is needed for the larger ST tires like 235/85 R16.
See for yourselfes in this list of Goodyear also LT with 6 li steps lower
History made the tire system bit messy, but it is as it is, I figured it out .
So dont shoot the messenger.

I have noticed that about my Goodyear Endurance also. I did a little research, can't remember where I found the information, but it seems they are initially filled with Nitrogen. This helps them to hold air. Something about the molecular structure of the Nitrogen.

The air we breath (and compress) is 71% nitrogen, so all tires are mostly filled with nitrogen.

I have never given weight a second thought relative to tire pressure. I have gotten the best tire wear and longevity running them at max cold pressure. Less road contact, less heat generation. I do the same with my vehicles. Getting 80K from a set of Michelins is hard to beat.
I just never thought about turning tire pressure into rocket science.
