I get to work today and as im walking away from the car to the door i hear air..sure enough i see a huge nail into my tire... Air emptyed out fast. I yanked the nail out and obviously had to go in for work. So my car sat 7 hours with a flat. Now i plan on getting a tire repair kit for 5$ and fixing it myself. Anyone ever do this and does it last? Stealership will do it for $27... Plan on getting at least one more winter or even two from this set. Advice appreciated! After patching it up is it worth filling tiire with slime? Will that help seal up the newly sealed hole for a stronger fix? Thanks guys!
