Automakers continue to eliminate spare tires from new vehicles in an effort to reduce weight and improve fuel economy. New research from AAA shows nearly one‐third (28 percent) of 2017 model year vehicles do not come with a spare tire as standard equipment.
This is often a surprise to drivers when they get a flat tire. Last year alone, AAA came to the rescue of more than 450,000 members nationwide and 5,500 in Oregon faced with a flat tire whose cars did not have a spare tire.
“AAA urges drivers to check their trunk for a spare tire before trouble strikes,” says Marie Dodds, public affairs director for AAA Oregon/Idaho. “Not having a spare tire can turn the relatively routine process of changing a tire at the roadside into a major hassle and costly situation that requires a tow to a repair facility.”
While new vehicles are equipped with tire pressure monitoring systems that alert drivers to low tire pressure, AAA’s roadside assistance data shows that tire-related problems continue to be one of the top reasons why members call for assistance. Even if drivers do have a spare tire, they are often reaching for their cell phones to call for roadside assistance rather than changing the tire themselves. According to a previous AAA survey, nearly 20 percent (39 million) of U.S. drivers do not know how to change a flat tire.
As a replacement for a spare tire, some automakers are including tire-inflator kits that can temporarily repair small punctures in flat tires. However, a 2015 AAA study found that tire-inflator kits have limited functionality and cannot provide even a temporary fix for many tire-related problems, including sidewall damage or blowouts. Not only are tire-inflator kits not a good substitute for a spare tire, they can cost up to 10 times more than a tire repair and have a shelf life of only four to eight years.
“Many newer vehicles are especially vulnerable to roadside tire trouble due to low-profile tires and the elimination of a spare tire,” adds Dodds.
AAA advises drivers to check their vehicle’s equipment and know what to do if you get a flat tire:
Do not assume there’s a spare. When purchasing a new vehicle, always ask for a detailed list of equipment and whether a spare tire can be purchased. A spare tire, and its accessories (e.g. jack, lug wrench), can cost up to $200.
Inspect all five tires. Check tire pressures monthly and have all tires inspected as part of routine maintenance. If your vehicle has a spare tire, be sure it’s properly inflated.
Read ahead. If your vehicle is equipped with a tire-inflator kit, read the owner’s manual and understand how it works and its limitations.
Check expiration dates. If your vehicle is equipped with a tire-inflator kit, check its expiration date. Most need to be replaced every four to eight years.
Consider roadside assistance coverage. Roadside assistance coverage can offer peace of mind when faced with roadside trouble, including a flat tire. To become a AAA member, visit AAA.com/join.
