# Tire storage guide

## How should tires be stored?

Tires should be stored in a cool, dry, dark location away from direct sunlight, ozone sources (motors, compressors), and chemicals. The ideal temperature range is 10–25 °C. Mounted tires on rims can be stored horizontally (stacked) or hung vertically on wall hooks. Unmounted tires should be stored upright (vertical) and never stacked flat for long periods, as the weight distorts the bead. Reduce tire pressure to around 15 PSI (1 bar) before long-term storage.

## How-to steps

- **Clean and inspect** Remove debris, mark tire positions if they will be reused, and reject tires with unsafe cracking, bulges, or puncture damage.
- **Choose the right position** Store mounted tires stacked or hung; store unmounted tires upright and rotate them periodically to reduce bead distortion.
- **Control the environment** Keep tires cool, dry, dark, and away from ozone sources, solvents, petroleum products, and direct sunlight.

## Environmental storage conditions

| Factor | Good | Bad | Why it matters |
| --- | --- | --- | --- |
| **Temperature** | 10–25 °C (50–77 °F) — stable, cool | Extreme heat (> 35 °C) or freeze-thaw cycles | Heat accelerates oxidation and ozone degradation of the rubber compound. |
| **Light & UV** | Dark storage — garage, basement, opaque bag | Direct sunlight or fluorescent light with UV output | UV radiation accelerates ozone cracking and surface degradation. |
| **Ozone sources** | Away from electric motors, arc welders, compressors | Storage next to workshop equipment | Ozone attacks rubber aggressively; causes sidewall cracking even without UV. |
| **Moisture** | Dry environment; avoid condensation | Damp basement without ventilation | Prolonged moisture exposure can cause bead corrosion on steel or alloy rims. |
| **Chemicals** | No contact with solvents, fuels, lubricants | Stored near oil drums, paint cans, fuel containers | Petroleum-based solvents swell and degrade rubber. |

## Stacking vs hanging vs upright: which position?

| Tire type | Best position | Avoid | Max stack height |
| --- | --- | --- | --- |
| **Mounted on rim (with tire)** | Horizontal stack (stacked flat) OR hung vertically on hooks | Standing upright for extended periods — rim bears point load at contact patch | 4 tires high (horizontal stack) |
| **Unmounted (tire only, no rim)** | Upright (vertical), side by side on a tire rack | Stacked flat — weight deforms the bead and oval-shapes the tire | Do not stack flat |

## Should you deflate tires for storage?

Yes — reduce pressure to around **15 PSI (1 bar)** before storing tires long-term. Full inflation over an extended period puts unnecessary stress on the sidewall and bead. However, do not fully deflate: a small amount of pressure maintains the tire's shape and prevents the sidewall from developing a flat spot.

When removing tires from storage, inflate to the vehicle manufacturer's recommended pressure before fitting.

## Tire bags — worth using?

Tire storage bags (large black polythene bags, one per tire) are recommended to:

- Exclude oxygen, which slows the ozone-oxidation process
- Block UV light
- Keep the tire surface clean
- Prevent cross-contamination with oil or chemical spills

Seal the bag with tape after removing as much air as possible. Reseal each time you open the bag. Dedicated tire totes with handles are a more durable alternative to single-use poly bags.

## How long can tires be stored?

Under ideal conditions (cool, dark, dry, bagged), tires can be stored for up to **6 years** without significant degradation. Beyond that, the rubber begins to harden and the tire may crack even if the tread depth is still acceptable.

Always check the **DOT manufacture date code** before fitting a stored tire. A tire manufactured more than 6–10 years ago should be replaced regardless of apparent condition. See our [Tire age guide](https://tirefitlab.com/learn/tire-age/) .

## Seasonal swap checklist

- Clean the tires with mild soapy water and allow to dry before storage.
- Check tread depth — record it; you'll know how much was used when you next fit them.
- Mark which position each tire came from (FL, FR, RL, RR) for rotation planning.
- Reduce pressure to ~15 PSI (1 bar) per tire.
- Bag individually (one tire per bag), seal, label with position and date.
- Store mounted tires stacked horizontally or on hooks; unmounted tires upright on a rack.
- When refitting, inflate to manufacturer spec and check pressures after 24 h.
