 Wait, did you say something? I just said action one ready? No. Try to remember some of the basics of CQC. Any real racer knows the most important thing about being a car guy is knowing lots of random information and then telling your friends and family even though they don't care. On that note, did you know a tire can tell you exactly how old it is if you just look right here? If we take a closer look at this Bridgestone tire wrapped around our sexy 18 inch forged cob wheel, you'll find the letters D-O-T on the sidewall. If you then look to the right, you'll find a four digit number. It's really two two digit numbers. The first pair represents the week of the year and the second is just the year. This tire says 2918, meaning it was made on the 29th week of 2018. So why should you care? If you're shopping for a used car, expecting a tires can give you hints about how the car was maintained or treated. On some all-wheel drive cars, it's important to change all four tires at the same time. Mismatched tires can cause excessive wear on the drivetrain. If a tire is only a few months old and is already worn down, you know that car has been driven really hard. On the flip side, if a tire appears new but the date is old, maybe that car has been sitting around for a long time. If you're buying new tires, the date doesn't have to match on all four but often they will and if not, it's a good idea to make sure at least one of them isn't way older than the rest. Lastly, if you're looking for a deal on cheap used tires, a lot of tire shops will refuse to mount tires past a certain age even if they have full tread. Now that you know some more random information that nobody cares about, get out there and tell them anyway. See ya!
