Tire pressure confusion - Legacy Elite 2 POLL

[John E Davies]

EDIT 10/02/22 This thread is for LE2 tandem axle only! Here is a related poll and thread for the smaller single axle trailer …. https://olivertraveltrailers.com/forums/topic/7376-elite-1-tire-pressures-poll-for-current-model-elite-1-only-with-lt-tires/
 

Everybody seems to be VERY confused about proper tire pressures. This has been an ongoing issue for as long as I have been on the forum, 7 YEARS. and with the proliferation of new hulls, it appears to be getting even worse. I actually started a service ticket long ago asking Oliver to include a Tire Pressure Load Chart, so we can accurately determine what is the right amount of air to carry the load. The sidewall pressure is the maximum the tire can take, not the correct pressure for the Oliver load!

This has not yet happened, here is the one I made for the older tires (I run mine at 42 psi, with an approximate 6000 pound trailer weight.):

From the 2022 Owners Manual

 

 

 

Here is the Tire Placard from Hull 218

IF YOUR PLACARD IS DIFFERENT FROM THIS PLEASE POST A PICTURE.

Please consider contacting Oliver with a new service ticket complaining about the continued lack of guidance. VERBAL recommendations given at DELIVERY vary wildly, are unreliable and should be received with a heavy dose of skepticism. 😳

Thanks.

It really is confusing because everyone seems to have a different answer! When we asked the service dept at Oliver we were told recommended psi is 55. 
 

[ScubaRx]

I keep the tires on the Outlaw Oliver, Hull #050 set between 60-65 psi. I formerly ran them all at 80 psi. I think that is too high.

As for running them at 55 psi, I think that is fine for most owners. The reason I run more is our trailer is heavier than most all the others (raised bed option, twin 5200 pound axles, 10 ply all steel tires, disc brakes).

As has been said MANY times in the past, everyone should buy and install a tire pressure monitoring system (TPMS). There are many brands available, Do your own research and select one based on your personal needs and wants.

Reminder that replying to the OP is useful, however it is not responding to the poll.   Please participate in the poll by checking the box and submitting  your vote.   It will be useful to all if we can see where we are, and the results might be beneficial to Oliver, if we can get enough data points.

The placard decal on 2021 Hull 797 is exactly the same as JD’s 2017.  I’ve already voted above, but  I run 45psi, check frequently with digital temp gun.  I have a TPMS.  I have tested the tire pressure several times by running them up to 60 psi for awhile on the highway, measuring temps, then airing down to 45, and checking temps again at next rest stop.   No noticeable temp increases.   If you are reluctant to reduce psi  this low, you could try this test yourself.    If your tires do not increase in temperature, your data confirms  you have made the right choice.   And more importantly (as JD pointed out), it is in accordance with the tire OEM.    Based on JD’s reported good performance, I’m going to try lowering  to 42 psi.  Running this low may not be for everyone, as we all run at different weights,  speeds, and road conditions.

John & Dave, appreciate the inflation charts.

Sent a request to Cooper for a inflation chart for the Cooper Discoverer HT3 Commercial Light Truck 225/75R/16 tires we installed last year, but no reply yet. Believe this is the current tire Oliver installs, too.

We keep our LE2 Ollie's ready to camp weigh around 4950 pounds with empty tanks except for full 6 gallon hot water heater that is full except for winter camping when Ollie's ready to camp weight is around 4900 pounds.

Like ScubaRX, we also have 5200 pound axles that were installed when Ollie was built, Oliver ran short on Dexter 3500 pound axles, so Legacy Elite Dexter  5200 pound axles were installed that have larger bearings and brakes.

We ran Ollie's trailer tire pressure at 50PSI cold for the last six years. The BF Goodrich Commercial LT tires that were original equipment & Cooper Discovery HT3 LT tires we  mounted have maximum capacity of 2680 pounds each @ 80PSI. The maximum weight we have on each tire (in our situation) is only 1238 pounds each without subtracting tongue weight on TV while towing.

Also thinking about reducing pressure on the next camping trip, probably 45PSI cold after discussion in another thread. I also keep a digital thermometer for checking various temps from bearings, tires, battery compartment, and anything that looks like it needs to be checked 🙂 on camping trips.

I also contacted Eric @ Cooper Tires with a request to provide load rating table.    He sent me the attached.  Note at 45 psi cold the LT rating equivalent to my Cooper Discoverer HT3 LT 225/75R/16 shows a max load rating of 1630 lbs per tire.  In my case, this is more weight than I typically travel with.

Mike,

Great, going to keep a copy in my operators manual and inflate accordingly, with first pressure reduction test to 45PSI. I still have not received a reply to my email request, but I did not contact Eric either.

Thanks,

Bill

Did they not get back to you?  I sent a request from the Cooper website a few days ago.    Note the table Eric sent me is from The Tire and Rim Association, Inc. 2017.   The Toyo table that @DavePhelps sent above is from The European Tyre and Rim Technical Organisation v2007.3.30.  I read the same value @ 45psi on both tables.

Not yet. I sent my request to cooperinfo@coopertire.com on 8/18/22. 

Oliver should include this information in their Ollie operators manual.

Great information, Thanks!

I just happened to find this video today and thought it could be helpful in regards to this thread. It does a great job of breakdown tires and tire pressure. Not saying it is perfect but helps level set on what all this is about.

Thanks, that is a terrific overview. One thing to mention … he talks about the tire placard, in his case it is for a ST 8 ply tire that originally came on his Airstream, so it shows a pressure of 65 psi. Which is also the max for any Load D 8 ply standard size tire….

 

. Only by referring to the manufacturer’s load chart was he able to determine the ideal pressure for his new set of LT 10 ply tires. He decided on 67 psi for his 9000 pound AS.

The Ollie Placard is for 10 ply Load E and 80 psi. I think Oliver should have a video just like this one, and ALSO tell us the correct pressure for the two trailers at their 5000 and 7000 lb max GVWs. And at lower weights! Just give us the proper chart(s).

  "No noticeable temp increases."

When I used my TST tpms this summer on my pop up trailer, I saw an increase in the temperature that stabilized.  I ran the tires at 50 and they increased to 59.  Temperature was not worrisome.   I will be towing our Oliver in November with a low weight as it will be new.  Any idea what we should air it up to?

John:

If you scrowl up in this post, you will see what varies people are using for pressure in their Oliver tires. Also in this post, it looks like Oliver is recommending 55 psi, but it is not noted if that is for the Elite or the Elite II.

Lots of varies answers however Oliver recommends 55psi. 

[Mike and Carol]

When you pick up your trailer the tires should be at the new recommended pressure (probably 55psi, not the old 80psi).  We’ve used 55 for thousands of miles and 50 for thousands of miles.  Both seem to be much better than the old 80psi which we used our first year.  We watch pressure and temperature on our TPMS and both increase in the heat and decrease in extreme cold.  No issues at either 50 or 55.  Mike

We use 55 to 60 on our older 2008, with st tires. Irrelevant for all the new trailers.

Let’s make very sure that everyone is aware that yours has a single axle, with 5000 pound GVWR, and those all need much more air (at their maximum towing weight) than the tandem axle model does. I would be running 60 to 65 with LT tires….

This thread is for LE2 tires. 😁

I was probably not clear on this point.   I was referring to the tire “stabilized” temps meaning the normal “warm” air pressure increases due to driving vs cold tire inflation.   My point was, when I increased & decreased  pressures ~15 psi, the tire temps did not increase or decrease significantly.  This leads me to conclude the tires are not under-inflated, which will cause temps to increase.    

[mossemi]

I have been running my stock Michelin LT tires at about 50 lbs.  I will add that at 60-65 mph my pressure does increase 3-5 lbs. after 10 minutes of drive time.  The thing I would like to mention, especially for new TPMS users is the effect of sunshine on tire temperatures.  For example, yesterday while driving north out of Florida, the curbside tires were running about 4 degrees warmer than the street side.  And of course that changes in the afternoon when the sun shines on the street side.

Still confusing because some are answering that have an elite 1 and some an elite 2.
This is an Elite 2 thread. 
Oliver recommended psi of 55 for the Elite II. Answers are all over the place for both models which brings the confusion. 
Maybe set up a poll for each model. Not sure how accurate the current one is if both elite 1 and elite 2 owners answered the current poll.🤷🏻‍♀️

[SeaDawg]

To alleviate confusion,  I split the three responses from Elite 1 owners to a new thread, even though each clearly identified themselves as Elite I  owners. Obviously, with a different trailer, single axle and two tires, our requirements will be different. 

I looked through the responses to the poll, and clearly, mostly Elite II owners responded to the poll, with the vast majority running 50 to 60 pounds. I'd say the poll pretty clearly shows most Elite Ii  owners are now running at the current Oliver recommended pressure,  somewhere plus or minus 55. Only 2 Elite owners that I saw actually responded to the poll, so it's pretty irrelevant to the numbers.

I came here just to say this.  Colorado sun is intense, and tire temperature fluctuates up  5-8 degrees!

Maybe the answer is the difference in the distance from the sun (Florida versus Colorado altitude) and/or the difference in atmospheric pressure? 😄

I think you may be on to something here. Because Mars is half again further from the sun than Earth, may explain why our tires run cooler there. 
 

Seems reasonable…

I just submitted a Service Ticket requesting a newer decal with 55 psi tire pressure recommendation.   I also recommended all previous owners be sent a decal, and a tech services bulletin to explain why.   Others might wish to do the same, perhaps OTT will respond to our request.

For an informal test, I watched my tire pressures and temps carefully on a recent 10 hour trip, measuring with TPMS, IR gun, and pressure gauge.  Mostly 65-70 mph Interstate,  fully loaded, but no water in fresh or gray tank.   Stopped a few times for gas, lunch & rest stop.   Cold tire pressure at start was 45 psi, 65F ambient and tire temp.  Sunny day in Georgia and Florida, ambient temps increased to 92F.  Tire temps reached 98F max, and tire pressures increased to 51psi max.   I’m confident in my family safety running my tires at 45 psi, use your own judgement.
