4 Facts about Compact Spare TiresMost of today’s drivers grew up with a vehicle that had a full size spare tire. It was truly convenient, unless it went flat awaiting use. In the case of a flat, all the driver had to do with replace the flat tire with the full size spare and they were on their way again. Then they could repair or replace the flat tire at their leisure and it would become their spare. Those days are mostly behind us. In fact, nearly all cars come with the compact spare tire, more commonly called the “donut”. While the “donut” spare is more maneuverable and lighter, it is different from having a full sized spare. We’ve come up with 4 facts you should remember about compact spare tires.

Compact Spare Tires, (also known as Donuts)

You’ll often find your compact spare tire in the base of your trunk, usually under a hatch or cover. It fits into the base of your trunk and barley takes up any room. The compact spare is already mounted and inflated on a small-diameter wheel. Contrary to what some people believe, it’s not meant to be a permanent replacement for your full-size wheel and tire. The compact spare is temporary and it only intended to assist you in an emergency so you can reach the nearest service station to have a new full-sized tire and wheel installed.

Compact Spare Tire – Driving Speed

Since the compact spare tire’s wheel is smaller – 50 miles per hour is the suggested maximum speed for a temporary spare tire. The tire is not designed for driving on the highway or maintaining highway speeds – remember, it’s just a short term solution to get you to a location where the full-sized tire can be repaired or replaced.

Compact Spare Tires – Driving Distance

You should always check with your manual, but in most cases, it is recommended that you not drive any farther than 50 miles on a “donut” spare tire. If you drive on it for too long or for longer distances than recommended it will surely result in a flat tire.

Safe Air Pressure for a Compact Spare Tire

Again, check your manual or the side of the tire for exact pressure recommendations for your compact spare. In general, a compact spare tire should be inflated to 60 pounds per square inch (psi) pressure. Check your spare monthly and add more air into your spare if it has dropped below the recommended pressure.
