2021 Hyundai Palisade — brake fluid is old but still looks clean — buyer question from Salt Lake City

This is a climate question as much as a tire question. In Salt Lake City, dedicated winters on the 2021 Hyundai Palisade paid off more than I expected on ice, even on plowed roads. Then you'll know the next fork. On “brake fluid is old but still looks,” that was the fork that mattered for me. This is from a 2021 Hyundai Palisade in Salt Lake City. Do that first. Might be overthinking it, but I'd rather overthink than overspend.
