Well I just hit 40000 miles, got an oil change, and while I was there I was trying to take care of my tire rewards program so I could get some new rubber. Well after they inspected the tires they brought me the papers and the tire measurements said 4/32 of an inch left. I laughed and said hmmm this is funny because 5000 miles ago the report I received say I have less than this and I asked the guy if I got more tread somehow (I was being a smart***). He was like sir we can go measure it you want so I said ok. We measure and he said yep 4/32's left and I said can we agree that the wear bars on tires are at 2/32's of an inch and he said ya. I said well looky there the tread is dead even with them. So I asked for a manager, who turned out to be a great guy, and the manager said oh ya we need to get that taken car of so I got my money and he ordered my tires! I wanted some Falken st/04s but they told me I have to order off of their list if I want the money from the rewards program so I went with some Michilen at2s! Anyways just wanted everybody to know that the program works!
