Ongoing abnormal treadwear issue?

[smashweights]

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 have some questions.
What’s your tire pressure?
How often are you rotating your tires?
How do you rotate them? Front to back, front to back with crossing… ect?
Are you positive there is nothing wore out or bent? (Bad wheel bearing, bad tie rod end, loose nut on a lower control arm, egg shape hole, bent upper control arm)
Any added weight on one side of the truck? (Ladder rack on that side ect)

It’s odd to me that two different places had to make changes to alignments… and you are still getting uneven tire wear. That almost tells me there is something worn out on the suspension. And depending on how they park it on the rack it will be slightly off.

Find a nice long straight parking lot when it’s dry outside. Take some sidewalk chalk and rub it on the tire. Do all four tires from the inside of the tread to the outside about 8 inches wide. Drive it in a straight line as far as you can and do not turn. Let me know what the chalk pattern looks like at all four corners.

I have been battling outside edge wear since new. Brand doesn't make a difference, it's the truck. As far as 'spec alignment' goes, they are very broad these days. So a truck can be in spec but the tires may still wear unevenly. I asked my shop to align closer to the inside edge of the spec. Seems to have helped. Rotation method will not help the issue. You could have the tires dismounted and remounted to change the direction of rotation. This would get you more miles out of your current set.

First two questions are answered in the OP. Rotate every 8k with oil changes. No idea what rotation pattern the shops use. I have no idea of anything is worn out but given how severe the asymmetric wear was in the original tires it would have to have been something that happened in the first 10k miles before I owned it. All three shops have made alignment changes in 30k miles, is it normal for the alignment to be off that frequently?

I asked about flipping the tires on the wheels to move the outer edge to the inner edge too extend the life as the inner edge doesn't wear.

I have 63k miles on my truck. I am on my third set of tires and had it aligned after the first set at 13k miles. Haven’t touched the alignment since.

What I am getting at is, yes its an ifs truck, yes they will wear little worse than most but not enough to having to flip tires on wheels.
It has to be alignment problem. If you are around my neck of the woods I have 2 places that I use. They are the only shops allowed to touch my truck or wife’s car.

Can anyone comment if the 2019 DS and DT with air ride have the same alignment specs? Should I have the dealer redo the alignment since the most recent seems to use the DS?

No idea on the DS.
Here are the specs. on DT.

My truck has the same wear. I actually think it could be aero mode. I spend so much time on the highway compared to city driving, that it's really the only thing that makes sense.

Although, I guess it wouldn't hurt to get it on an alignment rack to check things out.

I have a 2022 Limited crew cab, 6’4” bed. The OE Bridgestone tires wore out around 15,000 miles. Shoulder wear also. Put Michelin Defender and had Firestone align the front end with the Lifetime alignment. Had them redo it 3 times in the first 8 months and just took it back last month for the check and it was still within spec. They tweaked it a bit to put it in the middle of the range. Tires have 10,000 and look brand new.

That does help. My alignment should list the DS specs since that's what they used. Seems there's significant differences in the caster.

Both of these documents shows different numbers or degrees....I'm having the same issues with my tires and would like to take this info to see the difference if any to my tire shop that will be performing my alignment. Am I missing something? Thanks in advance!

Thread 'Tip for a successful alignment'

Jan 3, 2025

Hello all,

New here and just wanted to share some info regarding alignments when you have electronic power steering.

The story:
Scheduled an alignment on my 20 Rebel as I was needing new tires and knew something was slightly off. So I wanted everything set well before investing that kind of money. So I get the alignment first. Right off the lot something felt off. The truck tracked a lot straighter but the steering wheel was about 15 to 20 degrees to the right when holding straight. Correcting the wheel made the truck quickly go into oncoming traffic lane.

Got my tires anyways right...

AFAIK.
One is "check" specification, if it is within then fine.
The other is the "set to" specification numbers if an alignment is needed.
Not sure why they are written like that, the numbers line up in the end.

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.

Same as I saw.
Do you have air ride suspension?

Nah. ORG plus 1.8" on eibach shocks.

Outside wear is very common on the front steering tires due to cornering. The more aggressive you turn, the faster you run through round-abouts, tight corners, etc, the more you will notice this.

That's what came across as well when researching this issue. I live on alot of back country roads and have been known to drive....spiritedly.

I thought the same but this is beyond normal. The day I bought my truck I took it to the tire shop and put NRG 275/60/20 and 1.5inc top hat spacer since I have the ORP. This is my 2nd fifth gen and I had the same issue with my first one as well.
