2022 Lexus GX 460 — can I go one inch smaller for winter wheels?

Looking at a smaller-diameter winter setup for more sidewall. Main concern is brake clearance and keeping total tire diameter close. What measurements do you verify before ordering? Appreciate any ideas on what to check first.

Salt and cold mornings punish cheap shortcuts. Watch brake clearance and overall diameter if you downsize winter wheels on the 2022 Lexus GX. Then you'll know the next fork. Not gospel, but it saved me a headache. Happens in gear, not in park, for what that's worth.

This is a climate question as much as a tire question. In San Diego, dedicated winters on the 2022 Lexus GX paid off more than I expected on ice, even on plowed roads. That's where I'd start. On “can i go one inch smaller for,” that was the fork that mattered for me. Happy to compare notes if your setup is different. If your situation is the opposite, ignore me. Happens in gear, not in park, for what that's worth.

I'd pick the setup I'll actually live with in slush. In San Diego, dedicated winters on the 2022 Lexus GX paid off more than I expected on ice, even on plowed roads. I'd do that before spending real money. Run the total, not the monthly, before you commit. That's coming from doing this as an owner, not a shop. Happens in gear, not in park, for what that's worth.
