2021 Chevrolet Silverado 1500 LTZ 6.2 — can I go one inch smaller for winter wheels?

2021 Chevrolet Silverado 1500 LTZ 6.2, about 48,000 miles. 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? Trying to diagnose before I book a shop.

Salt and cold mornings punish cheap shortcuts. In Philadelphia, dedicated winters on the 2021 Chevrolet Silverado 1500 paid off more than I expected on ice, even on plowed roads. Then you'll know the next fork. Monthly payment math is how wallets disappear. Not driving it hard until I know more.

Fair point. Counterpoint: If Philadelphia only sees a few real storms, a good all-weather on the 2021 Chevrolet Silverado 1500 can be the saner daily. Then you'll know the next fork. The universe charges extra for guessing. Worth doing even if the car feels fine right now. Happens in gear, not in park, for what that's worth.

I'd pick the setup I'll actually live with in slush. If Philadelphia only sees a few real storms, a good all-weather on the 2021 Chevrolet Silverado 1500 can be the saner daily. I'd do that before spending real money. On “can i go one inch smaller for,” that was the fork that mattered for me. This is from a 2021 Chevrolet Silverado 1500 in Philadelphia with 48,000 miles. A shop burned me once by skipping that step. Heat soak after errands is the other window.

Trying not to diagnose from the couch.
