Crisp Mornings, Pumpkin Spice Lattes and Tire Pressure Lights!

Here in North Carolina we woke up to a surprisingly crisp morning. Fall came in like wrecking ball, as Miley would say. So, I shouldn’t have been surprised to that my tire pressure monitoring light was on. Why does the weather play a role in your tire pressure?

Did you know that hot weather is more likely to may make your tires over inflated and cold weather may cause your tires to be hazardously under-inflated?

Newer cars (mostly after 2000) have a tire pressure monitoring system (TPMS) built in for each wheel that constantly measures the inflation of that tire. You can read an earlier blog about TPMS and see a video on changing tires with them.

tpmslightWhen your tires differ from the recommended inflation pressure, your TPMS will activate and the light will come on, informing you to check the PSI in your tires. If your tire pressure has been set during the hot summer months, the first major cold wave will cause the air to contract inside your tire, lowering the pressure, thus setting off your TPMS.

According to a study conducted by TPMS sensor maker Schrader International Inc., many drivers still can’t identify the tire pressure monitoring system (TPMS) warning symbol on their vehicle’s dashboard. This study also found some other interesting facts about tire pressure, click here to see the results.

The TPMS measures your tires when they become significantly under-inflated. It’s important to check you car’s owners manual to see what is the recommended cold tire inflation PSI. Some vehicles will even tell you what the pressure is instead of just showing the warning light. Like on my Chevy Truck:

There is a relationship between the change in temperature outside and the pressure inside your tires. On mornings like this, where fall is in the air, your tire pressure will become significantly lower. Cars that sit outside all night will be affected more by the colder weather than those kept in a garage. Your tire pressure will decrease about 1 psi for every 10 degrees Fahrenheit the outside air temperature drops. (Likewise, it increases about 1 psi for every 10 degrees when the temperature rises.)

1. Only 15% of car owners properly check their tire pressure. Don’t be one of them. Check your tire pressure monthly. Don’t wait for the light to come on. Carry a tire gauge in your glove box, and check your tires once a month. Do this in the morning, when tires are cold. During this time, make sure all tires are at the PSI indicated in your manual.

2. As you drive, the friction will allow the tires to heat up, increasing the pressure. If you check your tire pressure after driving, you may have an inaccurate high-pressure reading.

According to https://www.accuweather.com, most tires can handle higher pressures resulting from driving and in hot weather, provided they were set at the “correct” pressure when it was cold.

3. If your TPMS light comes on, immediately check your tire inflation. You can also have a dealer or a mechanic check it for you. The light should go off once your tires reach the proper PSI, but check your manual as there may be a reset procedure to follow.

Do Not Ignore The Light

A June 2012 study by the Rubber Manufacturers Association reports that more than 80 percent of vehicles on our highways have at least one under inflated tire, which can reduce safety and handling, raise your fuel consumption, and can wears out the tires faster costing you money.

Cars have warning lights because it’s important. I’m going to repeat that, Cars have warning lights because it’s important. A car is something that needs to be maintained and up-to-date on all maintenance work in order to keep you safe and the car in good condition. Running on under-inflated tires will affect gas mileage and will substantially increase the wear on the tire. The biggest safety issue is that it can result in dangerous handling. Increased friction created while driving on under-inflated tires will cause tires to overheat and increase the risk of a blowout. Remember the Goodyear accidents from under-inflated tires?

So, now that my tires are at a safe pressure …. WELCOME FALL AND WARM COFFEE DRINKS! Have a great Monday!

Tire Changers: Breaking it Down

At the top of the list, with oil changes and brakes, changing and repairing tires is one of the most common jobs at your local repair shop. A good tire changer will, with regular maintenance and some repairs, last for many years.

Times are a changing in the tire-changing world! The days of easy steel rims and regular valve stems are fast disappearing. These days there are “soft” aluminum rims, tires with stiff sidewalls and TPMS (tire pressure monitoring system) valve stems that, if serviced improperly, can break. Click here to see how we change tires with TPMS. Keep this in mind when shopping for a new tire changer.

When you’re in the market for a tire changer, it’s hard to differentiate between all of the different brands out there, each company trying to put their best foot forward in a bid to win over your trust and loyalty. Each brand then has a variety of tire changer models, fashioned to meet the needs of specific niches. Here’s how you can easily select the right changer for you from Eagle Equipment.

Size Matters! What type and size of wheels do you want to work on?

The size of the wheel: Before you shop for a tire changer, you need to know what size tires you will be changing. Look at the rim diameter of the tires to be changed; 20 to 24 inch diameter is the common measurement of most wheels. If you want to go smaller, like motorcycles …. Or larger, like truck tires … that will determine if a different changer is needed.

The type of wheel: Light trucks will utilize a different tire changer from heavy-duty trucks. There are also shops that specialize in run flat tires or low profile wheels. Such tires require special tire changers because the ordinary models may not be able to handle too well.

The style tire shop that you are: Do you do a lot of tires? Are you just getting started? Do you want to be able to work on specialty tires or large truck-tires? The tire changer you choose will determine the style of shop you are.

With these factors in mind, we now need to look at the different types of tire changers available from Eagle. Each style has been designed for specific needs. Now that you know what type of tires you want to work on, here is how to easily find the one that fits. Continue reading Tire Changers: Breaking it Down

HOW-TO: Change a Tire with a Tire Pressure Monitoring System (TPMS) Sensor (VIDEO)

TPMS-tire-pressureA tire pressure monitoring system (TPMS) is an electronic system designed to monitor the air pressure inside the pneumatic tires on various types of vehicles. TPMS monitors the actual air pressure inside each tire via a sensor mounted within the tire behind the air valve. TPMS report real-time tire-pressure information to the driver of the vehicle, either via a gauge, a pictogram display, or a simple low-pressure warning light (which is to represent a flattened tire with exclamation point).

These systems were created for the luxury lines, with the first passenger vehicle to adopt it was the Porsche 959 in 1986. Since then, the system has proven that it can help you avoid traffic accidents due to under-inflated tires by early recognition of the malfunction of tires. It also increases overall fuel efficiency.
