What tires are you running?

My son picked them out, but the guy who sold them is a good friend of mine. They are not a major name brand, I'll have to look at home tonight.
35 ?? 18"

I can tell you with 100% confidence that tires can and will cause or help contribute to death wobble. With the advice of Sage Carli, I changed from a 35’’ BFG A/T to a 35” Toyo MT and with no other changes, the death wobble went away. I was actually trying to buy parts from Carli to fix it and he recommended I change tires to cure it. Better tire, more steel in the sidewall. I’ve run them over the last 10 years with no death wobble. Other tires may work as well but this is my experience.

That was my next step. I was going to borrow a set off a friends truck. We still may change the tires.

If you hit a few bumps in a row now, it does 3 very quick very light bounces and back to normal. No preying to Jesus death wobble LOL

Makes sense it would do that since you upped the air pressure. What happens is many tires sidewalls aren’t manufactured to carry the extra weight of the Cummins up front. That weight breaks down the sidewalls in short order. My truck has 235,000 miles on it on the Toyo tires. I run 45 in the front and 35 in the rear. I get at least 45,000 miles per set.

I had a set of toyo on something, nice tire, I have 2 3500 Dodge, the 99 I had Michelin then Firestone HT so I put the Firestone on the 01 also, them are working out good.

I priced 2 tires today, Toyo makes a 35x18 load range F, I figured I'd put 2 on the steer axle first to see what happens, that's a $700 gamble.

the tires on it are Mastercraft Courser load range E

he pulled a trailer to the dunes yesterday and made it, it just has the fast 3 bumps after you hit 3 or 4 bump in a row.

tire pressure to 75 and 2 turns on the lower control arms made the best headway so far.

I'm wondering if one more turn on the lower control arms would be wiser to do first? save him $700

45 PSI in the front tires and 35PSI in the rear tires is really low. It must work for you but I wouldn't recommend that for even an empty Dodge Cummins.

At those low tire pressures, the truck likely rides super soft and comfy, but like mush around corners.

That type of air pressure is also extremely dangerous also. The constant flexing of the sidewalls cause many problems including potential blowouts when least expecting them. Just looking back to the early 1990's when Ford and Firestone got into a spitting and pissing contest on the Explorer low recommended tire pressures. A few folks dead and then to be blown up in both companies.

Firestone recommended that to Ford, to the customers, to lower the pressure, the tire was proven junk later on.
