Auto manufacturers have eliminated the spare tire in many of their new models, opting instead for the use of run-flat tires or a portable tire repair kit. So far the trend has been most prevalent with higher-end vehicles, however General Motors recently introduced its new compact car, the Chevrolet Cruze sans spare tire.
Car makers today believe that the mandated implementation of tire pressure monitoring systems (TPMS) over the past several years has significantly reduced the likelihood that a flat tire will leave you stranded. In addition, eliminating the spare, including the jack and tools can reduce the car's weight by over 25 lbs. Decreased weight is one of the ways new car engineers are able to improve fuel economy.
Run-flat tires can allow you to continue to drive safely for 50 miles at up to 50 mph in most cases with 0 air pressure in the tire. Unfortunately, run-flat tires are more expensive than their non run-flat counterparts plus ride comfort and in some cases tread life can be less than stellar.
So if you don't have a spare but you don't like the idea of putting run-flat tires back on your car...what do you do?
Continental Tire North America, Inc. has introduced the ContiComfortKit (CCK) to the North American replacement market. This system is designed to temporarily seal a tire puncture and provide extended mobility up to 125 miles.
The ContiComfortKit comfortably restores mobility in a few easy steps. The kit is simply plugged into a 12v power outlet; a flexible hose at the other end is connected to the valve of the flat tire. Once the sealant tank is flipped up, a twelve volt compressor re-inflates the tire at the push of a button and simultaneously fills the tire with a latex based, liquid sealant, which seals the puncture. As a result, the tire can be used at a maximum speed of 50 mph for up to 125 miles. Drivers can get to the nearest tire shop and do not rely on road side assistance. A built-in light allows for easy use even at night.
The CCK is only 9.5" long, 7" wide and 4" high. It weighs only 5.5 pounds and does not require permanent installation. It is simple to use and provides mobility in minutes. It can be easily stored in the trunk of the vehicle. The kit can also be used as a compressor to check and monitor tire pressure through a built-in compressor and tire gauge.
The CCK has already been a success with car manufacturers. Since its introduction, it has obtained original equipment approvals for BMW, Ford and Volvo to name a few.
