Fellow 3500 owner, some experience on this topic. First thing, factory RAM 3500s come with Load E tires. The 40x13x5x17 Cooper STT Pro is a load C, which is technically “light truck, 10k GVWR”. Since I have a constant payload of 1500-1800 lbs full time, my death wobble came early at 2,500 miles. Well before even an early rotation at 5K as some might suggest to do. The Coopers did eventually wear out the track bar, and other components so even if you re-torque or replace those components the root cause might still be there and simply effect the new track bar, etc the same way and death wobble will return. I also had a customer with a violent blowout on the HWY with 10k miles on Coopers. There's enough of these Cooper tire experiences to not be anecdotal now (e.g. check AEV forums + cooper tires). I’ve rotated, road force balanced, etc and temporarily reduced but always came back. The Toyo's seem to handle this better, maybe because they seem to be a load D material wise (which was later confirmed by a Toyo rep). Ultimately from my experience and several customers with Coopers, they just don't hold up well. The Toyos are better, but maybe checkout the new 40" BFG HD Terrains, they are load F and are much better if you ever use the payload. I have a 3,400# payload on my Prospector and the intent was to use the payload and have this truck do it all (camp, haul, 5th wheel, trails, daily, etc). Just thought I would share and perhaps save you some time
@@4x4ready thank you! That’s was a treasure trove of knowledge right there. I think what you’re describing will be my story as well. Far as all the trackbar issues etc. I’ll look into the bfg. They make a good tire in the lower sizes. So if they put the same love into their 40’s that’s a win. I got mine for the same. I have a HQ19 camper. It’s heavy!! And a trailer etc. I wanted the end all of trucks. This seems to be it at the moment. Just need to address this issue.
@@iAmMarchal Yes, the HD Terrain 40" is very pricey but it handles the HWY speeds and everything else I use my truck for very comfortably and quietly. The Toyos have been outstanding as a few guys with a few years on there 3500 Prospectors have shown. They just rotate often (3-4k miles) and I've seen a few owners with 15k or 20k miles on the Toyos. Toyo's are almost half the cost of the new 40" BFGs as well. The Coopers are normally on smaller rigs a great tire, just tricky when you get into our 3500 12k GVWR territory is all. Nice truck man, you'll enjoy the BFG or Toyo I think and it will ride like new again and for longer.
You have to run Toyo M/Ts…I’ve run 4 sets on my PXL and now have over 135,000 miles. The AEV PXL was designed around the 40” Toyo M/T and it is heavier and has more rubber than other tires, which resist death wobble vs other tires. Speaking from real world testing and thousands of miles of towing, off-roading and 80 mph long hauls to Overland Expo’s in Arizona from Washington State. Rotate tires every 4000 miles. They ran Cooper’s because Toyo’s were back ordered. The new 40” BFG HD-Terrain looks promising but $5000 to try that setup due to initial cost of 18” Salta HD wheels vs $2300 for Toyo’s Also sell tires at 40-30% tread for $800 and keep new tires on the truck…roll $800 into new Toyo set ✅
I recommend putting a torque wrench on that front track bar to see if it has worked itself loose over time. It might not be a bad idea to check the ball joints to eliminate one other common death wobble culprit. - fellow PXL owner.
@@timhaight8021 thanks! I’ll check that as again tomorrow. I’d looked at the factory paint markings and they hadn’t moved a couple of months ago when I got my first wobble. Worth another look or maybe just torque again.
I rotate any AT/MT tire especially 33s or bigger every 3k miles. It’s worked for me over 100k total miles and even wear . Look at your tire pressure (chalk test is best) feathering on the edge like that looks to possibly be your toe adjustment. 35psi is a lot for a 40 inch tire, unless your towing to its full capacity you really want a chalk test and look for a even pattern that’ll give you your best results
I have Toyo and no wobble. Just rotated at 8k miles. Seem to be wearing ok. I’m going to remove the factory spare as it’s just taking up space. Not sure if I’m going to put a fuel tank, water tank, or just leave it empty. Have you thought about that? Sorry, kind of off track.
@@ShawnMinard-et5up I think the Toyo are a clear favorite. That’s my next time for sure. I’ve looked at that spare and thought the same. Just haven’t gotten around to removing. I wouldn’t mind an additional tank. The range isn’t the best from factory. I wish it was big enough to mount my 40” spare. I hate it in my bed.
I’ve heard of this being a major thing on these trucks especially the ones that have cooper tires. Even the guy I was going to buy the 22 3500 pxl said he got it a couple times and he had cooper tires. The trucks were originally with Toyo tires but for a while the company wasn’t able to get toyos so they switched to the coopers and it seems like that’s where the problem happens. Also supposed to rotate these every 5k miles. Not sure if it’s really the tires or something else that’s deeper with these trucks….
At minimum need you need to rotate your tires every 5000 miles. I change my oil in my power wagon every 5000 miles when I do that I rotate my tires I have the original tires on it with 52,000 miles they’re a 50,000 mile warranty I will definitely get 60,000 miles out of them

It's the "Death Wobble" effect....there's an active Forum on the topic.....Cooper Tires

@@JoseOrtiz_1416 I heard that about the 35 psi. I’m not towing all the time. What do you recommend for daily?
@@iAmMarchal on 40s I’ve done 25psi cold I find good, chalk testing would be your best bet to find the perfect tire pressure for your exact setup

Hey all, fun fact. You don't need 100K rigs to go off-roading and camping. Quit buying this stupid s**t.
This is true, however we can buy whatever the f(*& we want. =)
