Anyone else: Inside shoulder wearing much faster than rest of tire

RustEnthusiast12Community StarterDec 22, 20251993 Mazda RX-7 TouringChicago
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? Any data points from owners would help.

Don't overfit one forum story to your car. If it still isn't clear on the 1993 Mazda RX-7, a specialist hour can be cheaper than another round of parts. That's where I'd start. Write the result down so the next test isn't a repeat of the last one. If the story changes I'll post the new data.

Useful. I'll report back after I verify that on my 1993 Mazda RX-7. Wrote this up on my lunch break.

I'd push back a little: Verify the cheap/easy branch on the 1993 Mazda RX-7 before a big repair or a big spend. I'd do that before spending real money. Learned this the expensive way on a previous car. I've seen both outcomes, which is why I'd test instead of assume. Doing the boring step first on purpose.

I parked the 1993 Mazda RX-7 and wrote down what I already tested so I'm not repeating myself. Wrote this up on my lunch break.

Asking because it changes the advice: Verify the cheap/easy branch on the 1993 Mazda RX-7 before a big repair or a big spend. Then you'll know the next fork. Monthly payment math is how wallets disappear. I'll update if anything new shows up.

I'd keep this practical. Verify the cheap/easy branch on the 1993 Mazda RX-7 before a big repair or a big spend. That's where I'd start. Time, temperature, and whether it's in gear are the notes that actually help a shop. Worth doing even if the car feels fine right now. This is me being the wet blanket on purpose.

Write down what you already tried. A second data point from another 1993 Mazda RX-7 owner helps more than a generic diagnosis. Then you'll know the next fork. Run the total, not the monthly, before you commit. I'd rather be boring and correct. Might be overthinking it, but I'd rather overthink than overspend.

Don't overfit one forum story to your car. If it still isn't clear on the 1993 Mazda RX-7, a specialist hour can be cheaper than another round of parts. I'd do that before spending real money. Keep sale price, fees, and rate as three different conversations. I'm in no rush to be a hero on it.

Owner notes beat generic advice here. On the 1993 Mazda RX-7 in Chicago, 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. This is from a 1993 Mazda RX-7 in Chicago. Monthly payment math is how wallets disappear. That's my plan before I call anyone.

Yes, with one caveat: A second data point from another 1993 Mazda RX-7 owner helps more than a generic diagnosis. Then you'll know the next fork. Stop there until you know. This is the version I'd tell a friend.

I'd keep this practical. Verify the cheap/easy branch on the 1993 Mazda RX-7 before a big repair or a big spend. I'd do that before spending real money. If you share a photo of the worksheet, easier to sanity-check. This is me being the wet blanket on purpose.

I hear you, though I'd still want a second check. A second data point from another 1993 Mazda RX-7 owner helps more than a generic diagnosis. I'd do that before spending real money. Post the numbers (or the code) and people can get more specific. If this is nothing, great. I want that in data.
