Good morning. I’m Saul Reisman, here at Saul’s AUTOTEK, the leading automotive repair shop in Denver.
Today we’re going to talk a little bit about that tire pressure light on your dashboard — the one that looks like a horseshoe flashing at you. That little yellow half-circle, sticking its exclamation point in your face. That light is supposed to tell you to check your tire pressure, and alert you that one or more of your tires may be over- or under-inflated.
In Colorado, we see dynamic pressure changes very rapidly. With elevation changes, we see those dynamic pressure changes occur constantly. You’ll get thermal expansion and contraction of your tires. All of these things can affect the pressure inside your tires. Rather than assume that the gauge or the light on your dashboard is accurate, we strongly encourage Denver car and truck owners to play it old school and check their tires, or if there are any concerns at all, allow us to do such. We do it free of charge to ensure your safety, and that there are no concerns with your vehicle.
If your vehicle sees regular mountain use, and it’s the end of the season now, in the summer, and you’re getting ready to start the Colorado ski season, you need to be checking your tires. Every time you go up and down, your tires will be at a higher pressure than normal.
We recently had a vehicle come in that’s tires are factory-rated at 35 pounds recommended. The tire manufacturer says the most the tire can handle is 50. The owner hadn’t checked the tires in over two years and had been driving up and down from the eastern plains of Colorado to Vail Pass, repeatedly — twice a week.
The owner’s complaint when the vehicle came in, wasn’t of a tire light on but was of a shimmy in the front end. Felt like there was something out of round, or out of balance. The tires checked at 95 pounds on the front and 85 in the rear. These were literally ready to explode. This could have been a catastrophic failure and could have hurt somebody, all because that little tire light was on the dash, trying to give a “no,” saying “Please check us. Please let us know what’s going on.”
If your light’s on the dash, come by and see us. You got aftermarket wheels and tires, and you can’t get your lights to work right? We can point you in the right direction. Or, if you’re just concerned that you may actually have a low tire, we can definitely help you as well.
