Here's how it works: Screw the Thru-Core Emergency tire sealant bottle onto your valve stem. Immediately, tire repair sealant will dispense into your tire. Once the sealant has finished injecting into the tire (about 30 seconds), unscrew the Thru-Core can. Then attach the tire inflator to your valve stem and turn it on to fully inflate your tire! No jack, no mess, no hassle. You will be back on the road in just 12 minutes. The Smart Spair Plus is for standard tires and fits easily in a trunk. Sealant refill widely available
