Sorry to come off as a jerk by this next statement. To the people who are disagreeing with my post; where are you getting your information from, what training have you had, are you in the automotive field that deals with lifted/non lifted trucks/jeeps ect... ? Or are you going your info off your buddy,mom,dad,wiki,youtube,bathroom stall door....
Nice try. I work at the counter and do help back in the shop from time to time. Like I said, what do you do for a living? I do this for a living almost everyday and have for almost 25 years now. And the fact that you said a 10 ply tire makes me laugh being that the current ratings have NOTHING to do with the amount of layers(plies) in the construction of a tire. So if you're going to try and call me out like that better check YOUR facts first. FYI I'm currently running a F load range 35x12.50r20 on my 1500 @ 38 psiWhere are you? Off a pc screen at work? Go put 36psi in a 10ply tire on a 1500 truck and let me know how it wears 50k down the road and how bad they feel.
This isn’t uncommon knowledge.
If all else fails he can do the chalk test and confirm what us who have ran these tires have already said..

you never said what you do for a living. I've been having health issues that prevent me from doing it on a daily basis. If someone would not have tboned me last week I would take a video for you proving that not only me but the companies who've I had training through are right. So yet again keyboard warrior what do you do for a living?And I’m sure it feels floaty and will wear the edges out before 50k.
My last set toyos I had a little over 50k on them and I probably could have squeezed another 5k.
My current set I have around 30k on them.
And yes I’m aware there aren’t physically 10plys on modern tires but it’s a reference most people associate with.
But at least you help out in the shop from time to time.
Chalk test doesn’t lie

You're correct it's not rocket science but you are wrong on what you are saying about the pressure you should be running in these tires. I would believe you on mechanical stuff when it comes to helicopters if that's what you are doing. However when it comes to aftermarket tires that are not the same size/rating then the OEM ones that is MY field and what I do for a living. So why keep arguing with a professional in the field? I work with a lot of these tire manufactures on almost a daily basis. I'm not talking about the people who work in a call center who are given a blanket script, I'm talking about the people who develop these tires. I even on the occasion am part of the people who test different designs they are working on and give feed back on how to make them better. I posted up because I don't want people to spread miss information esp when it comes down to a safety thing. Which under/over inflating your tires can be. Basically in short please stop spreading information that is incorrect. Which in this case you are.

What suspension does your Rebel and your Laramie have? If they both have the coil spring suspension the suspensions are different and not the same. The manufacturer of the vehicles want certain pressures in the tires so the suspensions react and feel a certain way. Like I said in my org post here just because the amount (volume) of air increases to fill a larger void (tire) the pressure to create the patch and feed back does not change. (with in reason) IE going from a stock 28" tall tire to a 35" tall tire on the same size rim will not be a pleasant experience for the driver with out increasing the pressure of the tire to help reduce tire wobble. downside is it can and will make the tire more rigid "bouncy" and cause the center of the tire to wear prematurely. Now when you are not going a very large difference in size and staying with the same type of tire ie radial to radial or bias to bias then you want to be with in 5psi of the door sticker plus or minus to achieve a proper foot print and ride from the tire. As to why they want such a different psi on some of the Rebels. I do not know I did not design the truck or the suspension. Do me a favor since you keep talking about the chalk test. I want you to prove it. Video yourself doing the chalk test @ 10psi... 20psi... 36psi... 45psi... and 65psi. And show us the results in the video. I bet what you find will shock you.So explain to me why a normal ram 1500 and a rebel have two different psi ratings for two different types of tires on the same truck with the same capacity.
Are you saying if I put the Oem rebel tires on my normal 1500 I should run them at 36psi instead of the recommended 45 psi like the rebel even though they are the same truck?
Again, chalk test doesn’t lie.

Not exactly and that's kind of the problem. I'm saying do NOT go off what the sidewall of a tire says for the PSI it should be filled to. It's only showing the max it can handle not what it should be filled too. The door jam sticker on your vehicle has that information and does NOT change with tire size as I explained in a earlier post here. Now there is a grace of plus or minus 5 psi of that recommendation to get the desired ride for the end user. In certain situations you will def deviate from that IE when I go off-roading in my JEEP I run at 6-12psi depending on what I'm doing. When I'm driving it on the road the I air back up to 35 psi. (door sticker says 32) The og tire was a 215/75r15 "27-28" tall tire.Again, I maybe confused here, but aren't we almost all saying the same thing in some way or another?
In a nutshell Nick, what is it exactly you are saying about recommended tire pressures so we can be clear?
yea that's the only reason..............Because they are different rated tires. That’s why.
But I’m out.
Op has the info he needs from people who ran the tires he wants.
