Tire repair kits gain ground, but consumers still like spares
A tire repair kit includes a compressor that is powered by an electrical cord connected to the car's 12-volt outlet, like this Continental Tire's ContiSeal. The compressor pumps air and liquid latex sealant into the tire, which is re-inflated in five to 10 minutes. Such repair kits typically cost $40 to $100 in the aftermarket.
