– Inflator kits are one of car manufacturer’s current substitute for a spare tire. However, inflator kits are extremely limited in the damage that they can repair. Using the inflator along with the sealant is only effective on simple nail-type punctures that are clean through the center of the tire tread. With sidewall damage from curb strikes and potholes, or complete blowouts, these inflator/sealer kits are of no help.
The sealant in these kits can also damage tire-pressure monitoring systems. Some replacements ranging up to $300 – $400 apiece. Modern Spare designs and sells spare tire kits engineered specifically for your car. Our kits are a modern solution and a vast improvement over the factory-supplied solutions.
