Nearly Four in Ten New Cars Are Sold Without a Spare Tire

(HealthNewsDigeswwt.com) – Automakers have been under increased pressure from government agencies to produce more fuel-efficient vehicles. One way to accomplish this is by removing the spare tire and replacing it with a tire inflator kit. This reduces the weight of the vehicle providing for better fuel performance.  AAA tests revealed that the most common tire inflator kits worked well in some scenarios, but they are not a substitute for a spare tire. A tire inflator kit can only be used when a puncture occurs on the center tire tread and the object remains in the tire. These kits cannot be used if the object is no longer lodged in the tire, or if a blowout, pothole damage, or curb related damage occurs.  Such situations may leave a motorist stranded, requiring their vehicle to be towed.  Tire inflator kits have replaced spare tires on 29 million vehicles in the last 10 model years. While each four-pound kit eliminates approximately 30 pounds of weight, resulting in minimal savings in fuel consumption, the replacement cost can be high. Kits can cost as much as $300 per use depending on the type required, and have a shelf life of four to eight years.  AAA advises consumers that if you have a tire inflator kit, read the owner’s manual and understand system limitations before roadside trouble strikes.  When purchasing a new vehicle, don’t assume the new car comes equipped with a spare tire. Always ask sales staff for a detailed list of equipment and if a spare tire is available as an option.  If your vehicle has a spare tire, be sure it is properly inflated and stowed. Check tire pressure monthly, as a flat spare tire is of no value in an emergency.  Each year, AAA responds to more than four million emergency roadside assistance calls for tire service.
