Tire cupping

[brazzledazzle]

My 1500 has Falken Wildpeak at4w tires on it. Probably 40k miles on them. I notice on the fronts, mainly the driver side the outer edge is cupping. This happened on the original tires on the pickup as well. Both side but mainly the driver side. I know I need stabilizer bar end links done but this was happening before that. What might be the problem?

Just got one when I put the tires on initially. I wouldn't think it would get out of alignment already but could be.

Alignment, Tire PSI and Rotation

I do need to rotate them. I run anywhere from 36-40 psi. Seems to be the best right. When it warms up and it gets 40-42 I notice the vibration from the tires when going 60+

Yeah PSI and Rotation are a big thing. I know with BFGoodrich it's an issue

As everyone does, I want to wear the tire evenly instead of center wear like most seem to have. Any recs on psi that would be ideal? Really seems like the 36-40 is a good spot to be.

Best way, google chalk test, but I usually run around 38-40 on my Falken AT4W

Need to find a different shop to do the balance. Should not feel vibration at all speed after recent balance and rotate. how are the balancing, single plane or dual plane? Road force? These trucks ride better than most sedans. If you are driving at 45mph+ and your bottle of water is shaking in cup holder, something is not right.

I personally have mine balanced and rotated every 4-5k and run at 40 psi cold. Alignment checked every 2-3 rotates. Too many pot holes around here to trust alignment staying in check. Running 285/55r22 LT all terrains.

Agreed, this is my 6th Ram, with and without air suspension. They all have had issues with the cupping on the front. Have to rotate more often than recommended.

My '25 1500 Limited is my 5th Ram 4X4 and I rotate every 5K miles and have never had an issue with cupping.
