Surface rust underneath — treat now or leave it?

TireWeekend92Community StarterSep 4, 20262024 Ford F-150 Lariat 3.5 EcoBoostDetroit
I found surface rust starting on a few brackets and seams underneath. Nothing looks structurally bad yet. For a car that sees winter salt, what treatment actually slows it down without creating a mess later? Appreciate any ideas on what to check first.

This is a climate question as much as a tire question. In Detroit, dedicated winters on the 2024 Ford F-150 paid off more than I expected on ice, even on plowed roads. That's where I'd start. Not gospel, but it saved me a headache. I've seen both outcomes, which is why I'd test instead of assume. No warning lights, which is why I'm documenting it.

I'd pick the setup I'll actually live with in slush. If Detroit only sees a few real storms, a good all-weather on the 2024 Ford F-150 can be the saner daily. I'd do that before spending real money. On “treat now or leave it,” that was the fork that mattered for me. Take it or leave it — that's what I'd do. If your situation is the opposite, ignore me. If it repeats twice more I'll book time.

OP update: I tried the earlier suggestion and it only happens under that one condition. I'll poke at it this weekend.

Same neighborhood, different next step: Watch brake clearance and overall diameter if you downsize winter wheels on the 2024 Ford F-150. Then you'll know the next fork. When does it actually happen? Might be overthinking it, but I'd rather overthink than overspend.

I'd push back a little: In Detroit, dedicated winters on the 2024 Ford F-150 paid off more than I expected on ice, even on plowed roads. I'd do that before spending real money. A shop burned me once by skipping that step. Checking again after work.

I hear you, though I'd still want a second check. In Detroit, dedicated winters on the 2024 Ford F-150 paid off more than I expected on ice, even on plowed roads. That's where I'd start. On “treat now or leave it,” that was the fork that mattered for me. Take it or leave it — that's what I'd do. If your situation is the opposite, ignore me. I already checked the easy fluid levels.

On “treat now or leave it,” that was the fork that mattered for me. Had a similar mess a couple years ago and that's what finally sorted it. This is the filter I use when the thread starts repeating itself. Only after sitting overnight so far.
