Everything You Need to Know About Tire Indicator Bars

The automotive industry often shows its creativity in the small details. There are several examples of hidden car insights, one of which is that of tire wear indicator bars. This modest innovation is embedded in most tire treads to indicate when you are due for a new set of tires. While this detail is one that you may have missed in the past, a closer look can help you stay safe on the road. Here is everything you need to know about tread wear indicator bars.


What are Tire Wear Visual Indicator Bars?


Designed specifically to help you gauge your tire health, indicator bars are small tread marks that are cut off at the lowest safety point in your tire tread. These bars are often raised to 2/32”, the hazard point in most tires. When your tread aligns with the wear bars, it means you are ready for a new set of tires.


Why Does Tire Tread Matter? Safety, Inspections, and Efficiency


Tire tread provides the resistance necessary for starting, stopping, and steering properly. It grips the road and keeps you stable during turns and inclement weather. This level of control is essential to the safety of all vehicles on the road. Due to the hazards of worn tires, tread is examined on all NC vehicle safety inspections. Paying attention to your wear indicator bars can help you stay safe and avoid an inspection fail.


No Visual Indicator Bars? No Problem


Tire indicator bars are standard on new tires. However, if you do not see them or your tires are not equipped with indicators, that is no problem—the traditional ways of measuring tire tread still stand. One popular tread measurement is that of the Penny Test. Try inserting a penny into your tread with Lincoln upside down. This lets you see how close the tread is to Lincoln’s head. Once you can see the top of Lincoln’s head, it is time to replace your tires. We have a more detailed guide to checking your tire tread depth here! If you remain unsure if your tread is overly worn, bring your vehicle to a tire specialist. A trusted mechanic like Chapel Hill Tire will take a look at your tread for free to let you know if you need a new set of tires.

It can be hard to keep up with all of the care that your vehicle needs. When a light comes on in your dashboard or a mechanic lets you know you are due for a new service, this can surface lots of questions. One common source of service confusion is the coolant flush. Thankfully, Chapel Hill Tire has you covered. Here is a look at the answers to all of your common coolant flush questions. Is it Really Necessary to Flush Coolant? Perhaps the most common question surrounding this service is, “Are coolant flushes really necessary?” The short answer is YES.  Your engine creates friction and heat in order to run properly. However, your engine is also made of metal pieces, which are malleable and vulnerable when heated. Extensive heat can cause a blown radiator, cracked gasket head, warped cylinder, and melted seals, among numerous other serious, dangerous, and expensive issues. To protect your engine from this heat, your radiator contains coolant that absorbs excess heat. Over time, your coolant will become worn out, burnt, and contaminated, causing it to lose its cooling properties. While you might not like hearing that you are due for an extra service, coolant flushes are necessary for a safe and healthy vehicle. Does Coolant Matter During Cold Weather? As we approach the fall and winter temperatures, you may become increasingly tempted to ignore coolant services. Does coolant matter in the cold weather? Yes—the friction and power of your engine generate heat year-round. While the summer temperatures certainly do intensify engine heating, coolant is still incredibly important in the winter. Additionally, coolant contains antifreeze, which will protect your engine from the dangers of cold temperatures. What is the Difference Between Coolant and Radiator Fluid? When reading your owner’s manual or various resources online, you might find “coolant” and “radiator fluid” terms used interchangeably. So are they the same thing? Yes! Radiator fluid and coolant are different names for the same material. You might also find it referenced as “radiator coolant,” which offers the best of both worlds. Is Coolant the Same as Antifreeze? Another common question that drivers ask—“Is antifreeze the same thing as coolant?” No, these two are not quite the same. Rather, coolant is the substance used to regulate the temperature of your engine. Antifreeze is the substance within your coolant that prevents freezing in the winter. You might find some sources that refer to coolant as providing cooling properties only; however, since the coolant often contains antifreeze, it has widely become a general term that encompasses both. How Frequently Are Coolant Flushes Needed? Generally speaking, a coolant flush is often needed every five years or 30,000-40,000 miles. However, coolant flush cadence can be impacted by your driving patterns, local climate, vehicle age, make, and model, as well as other factors. Consult your owner’s manual or a local professional for insight on whether or not you are due for a coolant flush. Additionally, you can look for signs of a needed coolant flush. These include a sweet maple syrup car smell and vehicle engine overheating. Take a closer look at these and other signs of a needed coolant flush here . How Much Does a Coolant Flush Cost? Many mechanics try to hide their prices from customers, which can create questions, confusion, and unpleasant surprises. While we cannot speak for the costs you will face at other mechanic shops, Chapel Hill Tire offers transparent pricing for every coolant flush and other services . Our coolant flushes cost $161.80, which includes the safe disposal of your contaminated fluid, professional-grade cleaning of your cooling system to remove rust and sludge, high-quality new coolant, coolant conditioner to keep it preserved, and a visual inspection of your entire cooling system.

Oil Change Prices Why do most mechanics and dealerships hide the costs of their services? You might be wondering if they will try to take advantage of your visit and overprice their services. Or perhaps they think that their oil changes are so expensive that displaying their service costs would deter customers from visiting the shop. At Chapel Hill Tire, we value our customers, which is why we display transparent pricing for all of our services. Here is everything you need to know about the actual price of oil changes. What Does an Oil Change Involve? One of the most common vehicle services—and arguably the most important for keeping your engine protected—is the oil change . This product keeps your engine lubricated so that it can function without harmful friction. Over time, your oil becomes filled with debris, making it less effective in providing proper protection for your engine. Your oil levels also become depleted as your engine burns through your oil supply. This is where an oil change comes in. Not only do you need to supply your vehicle with oil, but you also need to remove the old oil and replace the filter that prevents the harmful debris from entering your engine. If you partner with an outstanding oil change expert, you will also receive routine vehicle checks included in the price of your oil change. On average, you need an oil change every 3,000 miles or every six months , whichever comes sooner. Maintaining regular oil change services will keep your vehicle protected and prevent costly engine damage from occurring. How Much Does an Oil Change Actually Cost? Every mechanic has to price their oil changes in a way that helps keep business open. However, you want to ensure that this number does not take advantage of your visit. Here is how much an oil change actually costs your mechanic: Oil Costs : Perhaps the most obvious expense, the mechanic will pay for several quarts of oil to fill your reserve. There are multiple different types of oil that vary in thickness, which can affect your oil change costs. If you take a look at your oil cap, it will tell you which type of oil your engine requires. Labor Cost : Here, you pay for the years of experience and the professional care provided by your oil change technician. You also reap the convenience of having an expert take care of your vehicle. Filter Cost : Your oil filter keeps contaminants out of your engine. These contaminants can wear away at your filter over time, which is why you require regular filter replacements. The cost of your filter may vary slightly depending on your vehicle make, model, trim, and year. Disposing of Used Oil Cost : Part of the hassle of an at-home oil change is navigating the disposal of the old, messy, and contaminated oil. An expert mechanic has the resources and an established process to ethically dispose of old oil. Collectively, what you pay will reflect the cost of the oil change for your mechanic. Even with all of these offerings, oil changes are often reasonably priced—usually running between $40-$70. You can also find oil change coupons to help offset the cost of this service. Transparent Oil Change Prices You won’t find hidden costs here at Chapel Hill Tire. Instead, we keep all of our prices clear and transparent on our services page . The only variance possible in this price is if your vehicle requires a filter or oil that is non-standard or higher in cost. This price includes five quarts of oil, an oil filter change, an air filter check, a fluid levels check, an inspection of your belts and hoses, and a tire air pressure check.
