GMC Tire Finder FAQ: How to Find the Right Tires for Your Vehicle

Four relatively small patches of rubber are all that connect your GMC to the road. Their pressure influences steering response, braking, tire wear, and efficiency, which makes maintaining correct GMC tire pressure considerably more important than the simplicity of the task might suggest. When the tire pressure light appears there's no need for panic. There is, however, good reason to investigate. For drivers around Old Saybrook, Connecticut, knowing what the warning means and what to check next can prevent a minor pressure issue from becoming a damaged tire. more First, Understand What the Light Is Telling You Your GMC's Tire Pressure Monitoring System, or TPMS, monitors tire inflation and alerts you when pressure in one or more tires falls below the appropriate threshold. The warning symbol resembles a tire cross-section with an exclamation point in the center. The light doesn't necessarily mean you've suffered a puncture. Tire pressure naturally changes with temperature, so a cold Connecticut morning can be enough to reduce pressure and trigger the warning. It does mean the pressures should be checked. A tire can be underinflated without looking obviously low, which is why relying on appearance alone isn't particularly accurate. Check the Tires Before Reaching for the Air Pump If the GMC tire pressure light illuminates while you're driving, find a safe place to stop and inspect the tires. A tire that appears substantially deflated, damaged, or unable to support the vehicle shouldn't simply be topped up and driven on. In that situation, seek appropriate roadside or professional assistance. If all 4 tires appear normal, use an accurate tire pressure gauge to check them. Compare your readings with the recommended cold tire pressures printed on the Tire and Loading Information label, generally found inside the driver's door area. Don't use the maximum pressure printed on the tire sidewall as your target. That figure describes the tire's maximum inflation specification, not necessarily the pressure GMC specifies for your vehicle. Temperature Can Explain an Apparently Sudden Warning A TPMS light appearing with the arrival of colder weather is a familiar occurrence. As ambient temperature drops, tire pressure also decreases. This can leave a tire that was correctly inflated during warmer weather below the vehicle's recommended pressure once Connecticut temperatures fall. Adjust each tire to the specified pressure when the tires are cold. After correcting the pressure and driving the vehicle, the warning may clear once the system recognizes the appropriate readings. If the light returns repeatedly, however, simply adding more air isn't a solution. A recurring loss of pressure suggests there may be a puncture, leaking valve stem, wheel issue, or another problem worth investigating. A Flashing Light Tells a Different Story There's an important distinction between a tire pressure warning that remains illuminated and one that flashes before staying on. A continuously illuminated light generally indicates a tire-pressure condition. A flashing TPMS warning can indicate a problem with the monitoring system itself. Sensors can develop faults or eventually require replacement. If your warning flashes, remains illuminated after the pressures have been corrected, or behaves inconsistently, our GMC service department can inspect the TPMS and determine what's causing the problem. Look Beyond Pressure When the Vehicle Feels Different Tire pressure is only one part of tire condition. Uneven tread wear, persistent vibration, steering that pulls to one side, visible tire damage, or repeated pressure loss all justify a closer inspection. Continuing to drive on an improperly inflated or damaged tire can accelerate wear and affect the way your GMC responds. A professional tire inspection can check for punctures and slow leaks, examine valve stems, evaluate tread condition, and test the pressure-monitoring system. Depending on what technicians find, your GMC may need a repair, tire rotation, sensor service, or replacement tires. Regular tire rotations and inspections through your GMC maintenance schedule can also help promote more even wear across the set.
