From Tire Review
 
ORLANDO, Fla. — AAA is warning consumers that the new car they’re considering buying may not have a spare tire.
 
"To meet new government fuel-efficiency standards, some vehicle manufacturers are omitting heavy spare tires and equipping new vehicles with an emergency sealant and inflator kit or tires that if damaged can run reasonable distances without air," AAA said.
 
New standards set by the Department of Transportation and Environmental Protection Agency require a combined 29.7 mpg for the 2012 model year, increasing to 34.1 mpg by 2016.
 
One way to meet these standards is by reducing vehicle weight. A spare tire, related tools and a jack can weigh more than 40 lbs. – weight that can be eliminated without adding cost to the vehicle.
 
"Unfortunately, many vehicle owners may be unaware that their vehicle has no spare tire until they experience a flat tire," said John Nielsen, AAA national director of auto buying and consumer information. "Consumers should review their owner’s manual and emergency maintenance supplies they have in the vehicle and be informed about alternatives to a spare to prevent panic or a delay when encountering a flat tire."
