Inside shoulder wearing much faster than rest of tire

ApexHauler73Community StarterJul 16, 20262023 Lincoln Navigator ReservePortland
2023 Lincoln Navigator Reserve, about 118,000 miles. Front tires look fine from the outside but the inner shoulders are nearly done. Car is lowered a little. I'd rather fix the alignment than just keep buying tires—what measurements should I ask the shop for besides toe?

I'd keep this practical. Verify the cheap/easy branch on the 2023 Lincoln Navigator before a big repair or a big spend. I'd do that before spending real money. I'd want that in writing, not as a promise. This is me being the wet blanket on purpose.

Write down what you already tried. A second data point from another 2023 Lincoln Navigator owner helps more than a generic diagnosis. That's where I'd start. I'd want that in writing, not as a promise. If this is nothing, great. I want that in data.

Owner notes beat generic advice here. On the 2023 Lincoln Navigator in Portland, I'd fix the thing you'll notice every day before chasing spec-sheet extras. That's where I'd start. On “inside shoulder wearing much faster than rest,” that was the fork that mattered for me. Verbal 'we'll take care of it' is not a plan. Climate here is different, so treat that as a local data point. Wrote this up on my lunch break.

This is from a 2023 Lincoln Navigator in Portland with 118,000 miles. Verbal 'we'll take care of it' is not a plan. This is the version I'd tell a friend.

Useful. I'll report back after I verify that on my 2023 Lincoln Navigator. If this is nothing, great. I want that in data.

Don't overfit one forum story to your car. If it still isn't clear on the 2023 Lincoln Navigator, a specialist hour can be cheaper than another round of parts. Then you'll know the next fork. This is from a 2023 Lincoln Navigator in Portland with 118,000 miles. I'd want that in writing, not as a promise. I'm keeping receipts and dates in one folder.

Asking because it changes the advice: Verify the cheap/easy branch on the 2023 Lincoln Navigator before a big repair or a big spend. Then you'll know the next fork. This is from a 2023 Lincoln Navigator in Portland with 118,000 miles. Parts cannon is a personality type I try to avoid. Doing the boring step first on purpose.

Verbal 'we'll take care of it' is not a plan. That's coming from doing this as an owner, not a shop. I'm keeping receipts and dates in one folder.

On “inside shoulder wearing much faster than rest,” that was the fork that mattered for me. Learned this the expensive way on a previous car. That's my plan before I call anyone.

I'll update if anything new shows up.
