Tire Storage 101: Clean, Stack, and Seal for Long Life

Decide what is worth storing

Good storage starts before the tire leaves the car. If a tire is worn near its tread wear indicators, has sidewall cracks, bulges, or an old DOT date code, storing it for another season usually just delays a replacement. Federal safety standards define tread wear indicators as the projections in the principal grooves designed to show how far the tread has worn, so take a close look before you commit a set to the garage.

Industry groups including the U.S. Tire Manufacturers Association and the Tire Industry Association emphasize inspection as the starting point for tire care; the same habit applies before storage. Check the sidewall markings and the DOT identification while the tires are still on the vehicle. If you are not sure whether the set has enough life left, the when to replace tires guide will help you decide.

Clean and dry before storage

Dirt, brake dust, and road grime hold moisture against the rubber while the tire sits through the off-season. Wash each tire and wheel with mild soap and water, work the tread grooves with a soft brush, and rinse thoroughly. Let the tires dry completely before you move them into storage or cover them.

Skip heavy dressings before storage. A light protective dressing can help, but a thick film collects dust and can leave the tire slippery to handle later. If you do apply a dressing, use it sparingly and let it dry. For more detail, see tire cleaning and care.

Choose the right storage space

Rubber ages fastest when it is hot, exposed to sunlight, or surrounded by ozone-producing equipment. Pick a cool, dry, dark space for the stored set. A basement corner or an interior closet often works better than an uninsulated garage, and a piece of cardboard or a wood pallet keeps tires off bare concrete.

Keep tires away from electric motors, battery chargers, welding equipment, solvents, and fuels. These items can create ozone or expose rubber to chemicals that make it brittle. The goal is a space where the tires will sit undisturbed and still be easy to reach at changeover time.

Signs of a poor storage spot:

• Direct sunlight or intense heat
• Electric motors and battery chargers
• Solvents, fuels, or strong chemicals
• Sharp objects, water leaks, or rodents

Stack or stand: how to store tires

The right method depends on whether the tire is still mounted on a wheel. An unmounted tire should not hang from a hook because the weight pulls on the bead. Stand it upright or stack it flat on a clean surface. A mounted wheel-and-tire assembly can be stored upright on a rack or stacked flat, but keep the pile low so the tires on the bottom are not distorted.

Before storing a mounted set, set each tire to the vehicle maker's recommended cold inflation pressure. That number is usually on a sticker in the driver's door jamb or in the owner's manual, not on the sidewall. If the wheels stay on the vehicle, storing at the recommended cold pressure also keeps a tire pressure monitoring system from warning about underinflation. Mark each tire's position before you remove it, then use tire rotation patterns when you put the set back on.

Seal, label, and cover

Once the tires are clean and dry, sealing them limits exposure to air, ozone, and dust. Slip each tire into a large opaque bag, press out the air, and close the opening. If you store tires in an area with rodents, a sealed bag also keeps them cleaner, though no bag keeps tires fresh forever.

Label each bag or tire with the position it came from and the date you put it away. That small step makes your seasonal changeover much easier in the spring. For tires that stay on a parked vehicle, use covers that block sunlight and check the vehicle occasionally. Idle months can create flat spots, so roll the vehicle a little or support it if it will sit for a long time. See tire flat spots for what to watch for.

Check when you bring them out

Storage does not stop tire aging. When you bring the set out, inspect each tire again for cracks, bulges, and stiffness, and look at the tread wear indicators before mounting. If a tire was already old when it went into storage, check the DOT date code first. Tire age and dry rot explains how rubber degrades over time.

Confirm the cold inflation pressure before the first drive, then follow a rotation schedule so the set wears evenly. Tires that sat clean and sealed should come out of storage looking much like they went in, ready for another season.

What to pick for your use

Questions

Should tires be stored inflated or deflated?

Store mounted tires at the vehicle maker's recommended cold inflation pressure, not at the maximum pressure printed on the sidewall. The recommended pressure is usually listed on a sticker in the driver's door jamb or in the owner's manual. Check pressure before storage and again before the first drive. See tire pressure basics.

Can I stack tires for long-term storage?

Yes. Unmounted tires can be stacked flat or stood upright in a clean, dry area. Keep the stack low, and never hang unmounted tires by the bead. Mounted wheel assemblies can be stacked or stood upright on a rack; whichever method you choose, do not overload the bottom tire.

Do tires go bad while they are stored?

Yes. Rubber ages even when it is not driven, so inspect the DOT identification before storing an older set. Federal safety standards define cracking as a parting within the tread, sidewall, or inner liner that extends to cord material, so visible cracks are a reason to replace the tire. Tire age and dry rot covers this in more depth.

Should I put tires in plastic bags?

A sealed bag keeps ozone and dust away from clean, dry rubber. Use a large opaque bag, push out as much air as you can, and close it tightly. Clean and dry the tires first; sealing moisture against the rubber is worse than leaving them unbagged. See tire storage in plastic bags.

Do I need to rotate tires before storing them?

You do not need to rotate just for storage, but marking each tire's position before removal makes remounting easier. When the set goes back on, follow a rotation pattern so wear stays even. For a refresher, see tire rotation patterns.

Can I store a vehicle with its tires on for months?

Yes, but keep the tires clean and at the recommended cold inflation pressure, cover the vehicle or the tires from sunlight, and check the vehicle periodically. Long idle periods can cause flat spots, so rolling the vehicle a short distance occasionally or supporting it helps. See tire pressure basics.
