Twice a year, a set of tires goes into storage in garages and sheds across the Flathead Valley, and how they're stored actually affects how they perform the next time they go back on the vehicle. It's not just a matter of finding floor space, a few habits make a real difference in how well tires hold up over months of sitting.
Mounted vs. Unmounted Storage
Tires still mounted on their own wheels have more flexibility in how they can be stored. Stacked flat, one on top of another, works fine for mounted tires, and hanging them on a wall rack works too. Unmounted tires, without a wheel inside them, are a different situation. Without a rim holding their shape, an unmounted tire should be stored standing up on its tread, not leaned against a wall or stacked flat, since sustained pressure in one spot can distort the sidewall over months of storage.
Keep Them Out of Direct Sun
UV exposure breaks down rubber compounds over time, which is true whether a tire is on the road or sitting in storage. A tire left in a spot that gets direct sun through a garage window or sits outside under a tarp ages faster than one kept in a shaded, enclosed space. If a covered garage or shed isn't an option, at minimum use an opaque cover rather than a clear one, and keep tires away from any south-facing window.
Temperature Stability Matters More Than People Think
A space that swings wildly between hot summer afternoons and freezing winter nights is harder on stored rubber than a space that stays relatively stable. An uninsulated shed or a garage with a lot of temperature swing accelerates the aging process compared to a more climate-stable basement or insulated garage. Not everyone has access to ideal storage, but it's worth knowing that "any garage" isn't automatically as good as "a temperature-stable garage."
Keep Them Away from Chemicals and Ozone Sources
Tires stored near certain chemicals, solvents, gasoline, some cleaning products, can degrade faster due to reactions with the rubber. Electric motors and some equipment generate ozone, which also accelerates rubber breakdown. It's a minor factor compared to sun and temperature, but if there's a choice between storage spots, keeping tires away from a workbench full of chemicals or an area near running equipment is the better call.
A Quick Check Before They Go Back On
When it's time for the next seasonal swap, a quick look over each tire before it goes back on the vehicle is worth the minute it takes. Check for any cracking that's developed in the sidewall, uneven or unexpected wear that wasn't there when they came off, and confirm pressure once they're mounted, since tires lose some air naturally over months of storage even without a leak.
Why This Matters More in the Flathead Valley
Households doing two swaps a year, spring and fall, are storing a full set of tires for roughly six months at a stretch, twice annually. That's a meaningful chunk of a tire's total lifespan spent sitting rather than rolling, which makes storage conditions matter more here than in places with a shorter or less consistent swap season.
What Flathead Mobile Tire Does
If you'd rather not deal with storage yourself, ask about it when you book a seasonal tire swap, which starts at $119.99 and includes balancing on our Hunter SmartWeight Elite as part of the price. We serve Evergreen and Kalispell along with the rest of the valley.
