A flat tire can be annoying, but when it happens on a deserted highway, or where there’s no highway at all, it can spell trouble.In this case, a tire-repair kit from Blackjack can literally save you. The company’s Kt340 kit provides everything you need for extracting whatever caused the flat, be it a nail, screwdriver, glass, etc. Also included are the special probes, needles and wrenches used for “dressing” the puncture and sealing it with the repair material (the BlackJack tire instructional video describes the entire process). Don’t forget you’ll need to keep a portable air compressor in your car to reinflate the tire. You can order this kit, which sells for $63, and examine the complete line of BlackJack tire repair products at www.blackjacktirerepair.com.
