Find out if he really did it, if he did just asking him to replace the tires. If he will not, I would drop it but add some secure system to your car, then do what you wish. Those cam we all get as pop-ups all the time are a cheap easy way to watch your truck (At home). I had my car in high school broke in to all the time and there is not much you can do. If you really mess up his car he will get p-oed and then he is cut your brake lines, or drain your tranny or diffs ….. Just take cause on retaliations (Sp?).
