Here’s a pretty standard question I hear from a lot of different people. When is it time to replace my tires? And how can I tell? Well, I’m no service technician or certified mechanic, but I’ve learned a couple things just from being around the car biz my whole life. I don’t know about you guys, but it’s easier for me to remember something if it’s catchy or unique. And to be honest, I think I heard this trick several years ago … and it’s stuck with me ever since. It’s called “The Penny Trick.” All you need is a penny and your wheels, check it out: [youtube]http://www.youtube.com/watch?v=_6DLILfDxrQ[/youtube] Pretty simple, right? Here’s even a bit more detail on how to check your tires. Now, I wanna know: What car “tricks” have you learned over the years? Anything that’s stuck with you as an easy way to keep your car on the road? Please share them with everyone in the comments.
