To ensure safety and prolong the life of your spare tire, consider your driving needs. If long-term reliability is essential, store a full-size spare in your vehicle. For occasional use, a compact spare can suffice, but be cautious of its limitations. Regularly check the tire pressure of whatever spare tire you have and replace it with a permanent solution as soon as possible. Always consult the vehicle owner’s manual for specific recommendations regarding spare tires.
