Unfortunately, many cars these days don’t have spare tires. In fact, one-third of cars in 2015 were missing one, according to the American Automobile Association. This goal is to save on gas but it’s not practical when you’re on the road. An extra tire can save you hours waiting for help. You can drive up to 50 miles on a spare, enough to get you to a comfortable place where you can wait for help. At least have an emergency flat tire inflator canister if a spare takes too much space.
