Are all spare tires 60 PSI?
No. Spare tires are not universally 60 psi; the required pressure depends on the spare type and the vehicle.
In practice, you’ll encounter several common configurations. Donut or temporary spares are typically around 60 psi, but the exact figure can vary by model. Full-size spares usually use the same cold tire pressure as the vehicle’s regular tires, which is specified on the door placard or in the owner’s manual. Some modern vehicles omit a spare entirely and rely on tire sealant kits or run-flat tires instead. Always consult your owner’s manual and the tire information placard for the precise requirement.
Types of spare tires and their typical pressures
Spare tires come in several forms, each requiring a different inflated pressure. The following outlines the main types and their typical guidelines.
- Donut (temporary spare) — typically inflated to around 60 psi, though some models specify slightly less or more; intended for limited distance and speed.
- Full-size spare — inflated to the vehicle's recommended cold tire pressure, usually the same as the normal tires; check the placard or owner's manual for the exact figure.
- Sealant kit or run-flat arrangement — some modern vehicles do not include a spare tire; instead they provide a tire sealant/inflator or rely on run-flat tires. No fixed spare psi applies here; use the kit as directed or seek service if needed.
When in doubt, always refer to the owner's manual and the tire information placard for your vehicle to confirm the correct pressure for the spare.
Practical guidance for spare tire use
To stay safe and avoid tire damage, follow these steps before driving on a spare.
- Locate the spare's recommended pressure in your owner's manual or on the door jamb placard and check the tire when it is cold.
- Inspect the spare for cracks, bulges, or leaks and verify the valve stem is in good condition.
- Inflate (or adjust) to the recommended cold pressure and recheck with a tire gauge.
- If using a donut, adhere to the speed and distance limits specified by the manufacturer and replace with a regular tire as soon as possible.
- When you install the spare, have the punctured tire repaired or replaced and return to normal driving conditions as soon as feasible.
Note: Driving long distances on a temporary spare can affect handling and safety. Full-size spares behave like regular tires, but you should still verify wear and compatibility with the vehicle’s systems.
Summary
Spare tire pressures are not standardized across all vehicles. Donut spares are commonly around 60 psi, but always verify with the owner’s manual. Full-size spares usually use the vehicle’s regular recommended tire pressure, while many new cars rely on sealant kits or run-flat designs instead of a traditional spare. Always check the official guidance for your specific vehicle and maintain the spare at the correct pressure so you’re prepared if a tire issue arises.
