I had a two set on my TJ (load range E 31"), no issues, longest lasting tire I ever had on it. The shits in the mud, but awesome for everything else. before that I had 30" load range C's on it, no issues, just wore a bit faster and were earlier generation. The load range E's on that jeep went nearly 50k, sold the jeep with them still on there and plenty of tread left. That was after 5-10k on my brothers bronco!


That said the Toyo r/t does seem alot better for mud. Still has small gaps so not comparable to a mt but it's quiet.

I posted a while back about why TPMS has been required in every vehicle since 2007 and that is about the same time that manufacturer tire pressure recommendations became a big deal. And the manufacturer tire pressure recommendations are going to be for GVW operation. So, if these tires came on your truck from the factory your door placard would say 40PSI front 50PSI rear with up to a 1.101 adjustment factor applied thereafter.

The more payload your vehicle has the more you are going to need to vary your tire pressures. Your Ram can weigh between 7,952LB and 12,300LB which is a huge difference. It can vary from 2,982LB to 7,000LB on the rear axle which is a huge difference. Anyone who tells you to run the same tire pressure on an axle with 2,982LB and 7,000LB doesn't know much.

I said that you are going to be in the range of 31-40PSI in the front tires and 18-50PSI in the rear tires. Obviously, don't be an idiot and hitch up to a trailer and double your rear axle weight without adjusting your tire pressures accordingly.
So tires have been great after they were balanced properly. I really did call AEV about tire pressures, and they said 60psi... I really don't get it.
I'm running them 40 front 40 back, mainly because of the weight in my toolbox, and there is always some sort of weight in the back of my truck... It's been working well so far. Thanks for all the feedback!

I've been wanting to add some kind of hydraulic steering ram to my truck ever since i've had it. Researched a bunch, but every conversion required some kind of bracket wedding wizardry that I wasn't comfortable with (or did't know how to do) Whatever....
So I crawled under the 40" Prospector XL (I think thats what they are calling it) today and saw that they had a PSC hydraulic ram where you would normally have the steering damper, there were hydraulic lines tied into the steering box that powered it. I tried to talk to the AEV rep but he didn't seam to know much about it. he said "Engineering doesn't really talk to there sales guys about the details."
Err... Ok... Seems like if you're at a trade show, showing off your product, you should know what it is you are trying to sell. Same with the whole tire pressure hoopla... "just run em' at 60 psi... you'll be fine!"
Any who....
So I dropped by the PSC booth and saw this... aww yeah! This kit is going to be available in the "near future" from PSC. It's all bolt on, with an upgraded steering box... Looks super dope. I plan to install this kit as soon as it comes out.
Attached is a picture of the PSC kit and two of what the AEV truck was running. Notice the hydraulic lines running into the steering box.

Do you know the AEV Rep's name by any chance? Where you at an event? Which day? We'll get to the bottom of that!

As for the PSC Ram, it works great on the 40" package and we do make some of our own bracketry but it will all soon be available.

So went to pick up 2000 bricks, 4 tons of sand, 30 bags of 80lbs mortar and some chimney parts. Total weight including trailer was 14,200 lbs.
One trailer tire was really low, but only noticed when the trailer was loaded.Made it to a gas station, but the couldn't pump more that 40 psi on the trailer. Useless.
Thought I would risk it, didn't really have much choice. Jumped on the highway, was cruising at 60 when the tire blew. Damn!
Luckily I had spare, switched it out on the side of road. (I'm terrified of being parked on the side of a highway. I was able to switch it out in about 15 min. Adrenalin.) That tire was also low. Limped it to the nearest garage and was able to pump the spare up to the proper pressure. Made it to the jobsite.
So this is what I learned:
-Suspension worked great, wasn't bottomed out at all. Front was a little higher,
I'm guessing tongue weight to be at about 800. More than I'd like, the forklift driver didn't feel like re-adjusting my load so I just left it. But it didn't post any issues.
-I need to re-gear, the truck wasn't really happy going 60. I kept it in 5th and it did fine. Unloaded, 3:73s are great. You can cruise all day going 80-85 at 1500 rpm. I'm thinking of re-gearing to 4:30s.
-I need an on-board air compressor! Hmmmm... Compressor, re-gear, lockers!
Makes sense to me!
That said, will a ARB compressor pump tires up to 70-80 psi?
A couple a pics...

I bet you have more tonque than 800lbs (awesome pics for comparison thanks!).

Mine (2500) doesn't squat that much with 1,100 or so. I bet you were up around 1,500 or more (10% tonque weight, but but you were higher?).

no experience yet with ARB pumping 37" tires yet (I have the small one).

I can see how 3.73 would not be good for something that heavy for sure w/ auto trans. If you go 4.30 keep us posted, you'd be the first I've seen. I'd like to go there for 40" tires.

If I had 40's I'd really consider 5:13's especially if off road a lot.

Is anyone running 37's with 4:56 or is 4:10 the go to?

When I had my 2-door Tahoe with 38's I switched to 4:10's and still blew through them about every other year. Granted I had a 12 bolt rear and really needed to upgrade to a 14 bolt or DANA 70.

If you squat that bad when towing have you ever considered Timbrens? They take about 5 min to install and seem to work really well for our trucks.

You really need to keep in mind which powertrain your talking about. I have now had the opportunity to try several ratios in different trucks.

We have a 37" 6-45/CRD that has 4.10s which seems perfect. Its lower geared than the stock 3.42/33.5 set up and I towed an 18,500 boat around last week and it felt great. 4.30 would be ok on the street I feel, but definitely on the low end when not towing.

In my 3500 camper with a Aisin/CRD and 41"s I went with the 4.30 and feels pretty good, that's about the same as stock. I couldn't get the real 4.56's which is what I wanted initially. AAM is on permanent backorder status it seems.

In my CRD/G56 with 41"s it seems geared well with 4.10. 4.30 might be slightly better...

Doing a Gas/40" truck would definitely need 4.88 or numerically higher. I'm not sure these gears exist yet with the large pinion in the newer Rams. Yes, I know some places will use an adapter bearing and run the older gears in the newer axles, but that seems odd to be going to larger tires and running a smaller pinion...we tried a few sets of the 4.56 like this and they all made trailing throttle noise, even though they were set up correctly.

Edit: I think these are the large pinion...http://www.justdifferentials.com/GPR...500-select.htm

Dave - is that a 3500 w/ air bags?
