2024 Lexus RX — going one inch smaller for winter wheels — second opinion before I spend money

ManualOwner954Community StarterSep 4, 20262024 Lexus RX 350hPhoenix
2024 Lexus RX 350h, about 28,000 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?

I'd pick the setup I'll actually live with in slush. In Phoenix, dedicated winters on the 2024 Lexus RX paid off more than I expected on ice, even on plowed roads. Then you'll know the next fork. Was this after sitting overnight? Parking it somewhere I can hear it better next time.

Not convinced that's the whole story. Watch brake clearance and overall diameter if you downsize winter wheels on the 2024 Lexus RX. I'd do that before spending real money. Run the total, not the monthly, before you commit. I've seen both outcomes, which is why I'd test instead of assume. Not driving it hard until I know more.

This is a climate question as much as a tire question. Watch brake clearance and overall diameter if you downsize winter wheels on the 2024 Lexus RX. That's where I'd start. On “going one inch smaller for winter wheels,” that was the fork that mattered for me. This is from a 2024 Lexus RX in Phoenix with 28,000 miles. Any freeze-frame data saved? Video is ugly but it shows the hesitation.

Learned this the expensive way on a previous car. I'd rather be boring and correct. I already checked the easy fluid levels.

Salt and cold mornings punish cheap shortcuts. In Phoenix, dedicated winters on the 2024 Lexus RX paid off more than I expected on ice, even on plowed roads. Then you'll know the next fork. Verbal 'we'll take care of it' is not a plan. I keep a notes app thread for this now.

This is a climate question as much as a tire question. If Phoenix only sees a few real storms, a good all-weather on the 2024 Lexus RX can be the saner daily. Then you'll know the next fork. On “going one inch smaller for winter wheels,” that was the fork that mattered for me. If they can't show the line item, I assume it's hiding. If your situation is the opposite, ignore me. Parking it somewhere I can hear it better next time.

If it doesn't change the out-the-door or the repair estimate, it's noise. Your commute and mine probably aren't the same, but the test still applies. Not driving it hard until I know more.

OP update: I tried the earlier suggestion and it only happens under that one condition. I keep a notes app thread for this now.
