Bad tire luck, leads to new tires

For the last few weeks, I've been fighting my rear passenger tire. It had a small nail in it, but for the most part was holding air. One day on the way home from work the nail came out while driving and I was down to the rim before I could get home. Pulled over, plugged it good to go. The next morning on the way to work, I had lost all pressure again, come to find out the same tire had a bolt in, I was pissed, so in came fix a flat, and it finally stabilized , more than it was...lolbut the air was still slowly leaking.. so for the last couple weeks every morning I had to air it up just to be safeand just when I thought I could limp this tire along..I was on my way to work on Saturday morning when our of nowhere, my driver side rear went from 38....27...26..25...24.....hit 0 psi before I could even stopcome to find out it had a nice surprise in it................so after being royally pissed off, I finally broke down and just got a whole new set, and I tin it looks much better now, kept the same size 245/60R20.
