WORST DAY EVER

So... as I was driving to work today my good ol' tire blew out.. Well see almost a year ago when Hurrican Gustav hit my car got a flat while i was parading around in the hurricane (bright i know) I took my car to the tire shop and they patched it but, i also noticed i had slashes in the tire. There were only 2 at first then they continued to expand and eventually there were about 6. So I just continued to put air in the tire everytime it went down and didnt decide to get a new one. Hey a new tire for my car is bout 150 dollars.. NO INDEED i refused to pay it. Well maybe I shouldve just went ahead and paid it cause today it BLEW OUT!! Luckily I was only a block away from my job. I had to ride on my rim :( to park the car, and walk to work in the blistering 90 degree weather with 1000% humidity i swear- SWEAT MUCH!!. But, heres the bad thing. I DONT have the thing to take the lugs off.. WOOPS. My brothers supposed to come change it so we'll see. As long as its done by 9 tonight, Ill be okay. But, maybe I shouldve just avoided this and spend the money for a new tire right?!?! LESSON LEARNED!!!
