So maybe one of the most common places to find car myths is tires. This maybe cause by several reasons but I think rumors or lack of knowledge may have started these. So I would like to assume that if your reading this you know what a tire is and if your not sure you can Google it, or wait about a week when we cover tires in full.
So Myth 1: Air Pressure
This is the stem of the most popular myths regarding tires. And I think it may come from the numbers molded into the side of the tires you buy. When looking at the tire side wall you will see all kinds of information regarding the tire and somewhere on there you will see a number like 45psi, or what have you. This my friend is not the recommended pressure. This is the maximum pressure that, that tire can be inflated to. So what is the recommended tire pressure? Well you can look in your cars manual, or inside the Driver’s door. Well what if I lost my manual and there isn’t a sticker in there. The best thing then is to call your local auto dealer (preferably one for your car make). This number, or pressure is what that car manufacturer has found to be the best tire pressure, not only for traction but overall handling.
So the truth, look for the cars tire pressure not that number on the side of the tire, well look at it but do fill to this pressure, unless perhaps it some how matches that sticker number.
Well Myth 2: Rotating
There are several myths just wrapped into rotating your tires. Like you can only move tires from the front to the back or what have you. Well, while this may have been true a couple decades or more ago, it no longer holds true. With standard radial, multi-directional tires you should actually rotate in a “Z” pattern. Meaning, starting with the front driver tire to the passenger side and that tire to the back driver side and the back driver side to the back passenger, and the last tire up to the front driver side. The moves the tires all over and promotes even wear.
But what id I have directional tires? Well then you are back to the old ways of back and forth rotations, unless you actually remove the tire from the wheel and then move the tires across to the other side of the car.
And finally what if you have 9.5 inch tires in the back and 8 inch tires in the front and they are directional tires? Well my friend you will not be rotating your tires every 6,000 – 8,000 miles.
We will be adding a couple more tire myths tomorrow so keep tuned.
