Full-Size Matching Spare Tire:
A fifth full-size tire that matches the current set of tires on your vehicle. If you're using a full-size matching tire as your "spare" remember to make it part of your vehicle's tire rotation pattern.
Full-Size Non-Matching Spare Tire:
A fifth full-size tire that does not match the current set of tires on your vehicle. Although this tire is a full-size tire, it may not be the same size as the ground tires. The wheel may also be different than the wheels on which the ground tires are mounted. A full-size non-matching spare should not be a part of your vehicle's tire rotation pattern.
Compact Temporary Spare Tire:
Lightweight with a shallow tread depth, these spare tires have much smaller dimensions and require a higher inflation pressure than both standard and temporary spare tires –generally 60 psi.
Folding Temporary Spare Tire:
An inflatable or collapsible temporary spare tire.
