These days, distracted drivers and dangerously narrow roadsides make changing a flat tire riskier than ever! Instead, repair your tire quickly with  a high pressure compressor that not only inflates your tire, but pumps in a particle gel sealant to repair punctures, so you can safely drive up to 120 miles to get a permanent repair! So easy and effective, leading automotive manufacturers around the world are replacing heavy spare tires with these German engineered systems. Just plug into your car's DC outlet — water-based sealant closes multiple cuts up to 1/4 inch wide, and is safe for tires, rims and tire pressure sensors, yet is easily removed for permanent repairs. Use in any temperature, day or night
