Things I Learned at the Tire Store
Waiting on my new tires to be installed, I stared for WAY too long at the various tire options ... This is going to be the least-interesting list ever!
- •Because tires are incredibly diverse
- •I mean sure, they're all round and blackBut the similarities end there
- •So I've been pacing... And Googling. Here's what I learned.
- •Each tire has at least three numbers
- •The first number is the tire width in millimeters.215 in this case
- •The next number is the aspect ratio, essentially the height of the tire.In this case, 60 means that the tire is 60% height-to-width.
- •The letter denotes the tire's constructionR is most common and is short for "radial." Not short for radius as I assumed.
- •The last number is the diameter of the wheel that the tire is going to be mounted on.17 inches in this case
- •Yes, they're mixing Metric and Imperial measurements.Apparently, wheels come from England and tires come from France. Or something.
- •And there's the tire warranty. Usually 30,000-100,000 miles. This is a best guess of how many miles of usage you should get under normal conditions and with normal maintenance.But if tires do come from France, shouldn't the warranty be in kilometers?
- •Then there are all sorts of treads
- •For cars
- •And trucks
- •And redneck trucks
- •And trailers
- •Now I'M tired.
- •Is my car ready yet?
- •Please hurry! I'm about to start Googling motor oil viscosities.
