1999 Toyota 4Runner — going one inch smaller for winter wheels

DealHaulerCommunity StarterSep 4, 20261999 Toyota 4Runner SR5Austin
1999 Toyota 4Runner SR5, about 208,000 miles. I want smaller winter wheels for more sidewall. Overall tire diameter can stay close, but I am worried about caliper and spoke clearance. What measurements should be checked before ordering?

Salt and cold mornings punish cheap shortcuts. Watch brake clearance and overall diameter if you downsize winter wheels on the 1999 Toyota 4Runner. That's where I'd start. On “going one inch smaller for winter wheels,” that was the fork that mattered for me. Write the result down so the next test isn't a repeat of the last one. Cold start is when I can actually reproduce it.

This is a climate question as much as a tire question. If Austin only sees a few real storms, a good all-weather on the 1999 Toyota 4Runner can be the saner daily. I'd do that before spending real money. This is from a 1999 Toyota 4Runner in Austin with 208,000 miles. Happy to compare notes if your setup is different. A day of patience here is cheaper than a wrong part. Cold start is when I can actually reproduce it.

I parked the 1999 Toyota 4Runner and wrote down what I already tested so I'm not repeating myself. I'd rather pay for diagnosis than a second guess-repair.
