Ongoing abnormal treadwear issue?

[akostaac]

I made a post about this the other day but I'm also dealing with this issue. Took to the dealer and they saw no issue with the alignment. It's the very outer edge. I'd say about 1/2 of the outer tread pattern is measuring 8/32-9/32. All other tread is at 11/32. I'm on General Grabber ATX 275/65r20 tires at 25k miles. Rotated regularly at 5000-5500 miles.

My alignment shop looked my truck yesterday and realized the truck seemed to be within specs but since you got a range to play with they went opposite of what it was but within specs and you can actually see the difference in the front tires when looking how the tire is on flat ground

Yea I've noticed the positive camber when my truck is parked and the wheels are turned. I was thinking of getting them to introduce some slight negative camber just to offset the difference.

I don't doubt that. Just turning the wheel to max left or right on flat ground you can see the wheels seem to camber to the outside edge. But wearing a 1" strip twice as fast as the tire is rated seems excessive.

Do everyone's tires tilt that far on steering?

Don't know what to tell ya, I've had the same issue on every vehicle I've ever owned. The most common denominator is the driver.

Tire shops will tell you not to do this, but I have owned multiple rams and had the same success on each. If I run at door sticker tire pressure(36psi), I have cupping and bad wear on the outer rows of treads within 3k miles. I have ran Goodyear, Cooper and Bridgestone tires. All have the same outcome. I run 40psi cold and rotate and balance every 5-6k. Tread wear is even across the tires. The frequency of rotation keeps the cupping non existent. An alignment every 20k for good measure. All 4x4 crew can 1500s. The 3 Limiteds all have air ride and use aero mode on highway, 70% of my miles minimal towing.

My tire shop has even asked how I get the even wear with over the 200k miles between the trucks, but they cannot tell others as it is a liability.

Totally get what you are saying but this is not my issue. This is my 4th Ram 1500 since the 3rd Gen. Never had an issue before. My 4th gen was lifted w 35 NRG tires and no issue. My first 5th gen 2021 I had it for about 10k before I traded in for a new 2022 BTS edition. Anyhow the shop made some adjustments yesterday so we will see how it goes. For the record I’m running 275/60r20 xl NRG at 41psi since the day I picked up the truck new. I changed 2 tires at around 20k and tires get rotated every oil change

Eh, I run 38psi on stock size tires. I can't imagine an extra 2psi is going to make a tire edge go from toast at 30k miles to lasting a normal 60k

I noted this abnormal wear pattern on my stock Bridgestone Dueler H/L tires, posted about it here and the consensus was alignment issue. Wear pattern seemed to fit with a toe problem. So I had the OEM Duelers replaced at 34k miles with Conti TerrainContact H/T XL tires at that time in March 2022. I had the shop do an alignment then, not much was off, very slight right toe off, and the front right/passenger tire seemed to wear this spot fastest. Had them redo the alignment a year later at 44k miles (had a 1 year alignment plan) and toe went slightly off the opposite end of spec. I'm now sitting at almost 60k miles and the outer edge/toe wear seems to be developed on the new tires as well. I had to take the truck in to the dealership anyway for the ABS/ESC recall and asked them about the wear. They "didn't notice any abnormal wear" but rec'd doing an alignment again. Seems the caster was way out of spec and comparing the previous non-dealership alignments the specs they used were slightly off and a little high even post-alignment.

Interestingly, the initial alignment lists the truck as "DT... Lifted Rebel/Off-road" which it's not a lifted rebel/ORG and the second lists it as "DT... steel suspension" instead of air ride. The dealership here put it as a DS, so has no one ever used the correct truck for an alignment???

So here I am still noticing this outer edge wear with new tires and 2 alignments after about 26k miles. The horrible wear is the OEM tires for comparison but if you look at the treads on the new tires, you'll see the siping is nearly or completely toast on the outer edge in a similar area to the OEM tires. I have had the tires rotated and re-balanced with every oil change and am religious about keeping my tire pressures around 36-38psi cold. These are 70k warranty tires and i'm not even halfway through that rating and i'm concerned the outer edge is going to significantly impair the lifespan yet again. Any other suggestions?

I’d have the dealership check out your rack and pinion. I’m on my second RAM 1500 Limited—my 2023 has 29K miles, and the stock tires are already shot. On my previous 2019 Limited, I had to replace the tires at 26K miles due to excessive wear. Both trucks came with tires rated for 65K miles—Goodyears on the 2019 and Pirellis on the 2023—yet they’re wearing out in less than half that time. So, I agree there’s something going on with the truck.

I suspect it’s linked to the rack and pinion failing. My 2019 needed a rack and pinion replacement at 55K miles, and at this point, I’m just waiting for the same issue to happen on my 2023.

Not saying you're incorrect - I just wouldn't put much stock in your OEM factory tires. They're often not rated the same as the ones you'd have put on by say discount tire. You can find hundreds of accounts of people replacing their factory tires around 25-30k miles.
