The recommended tire inflation pressure for your vehicle is more than just a number; it’s a carefully calculated value designed by automotive engineers to enhance your car’s performance, traction, and ride quality. Your tires bear the weight of your vehicle as it accelerates, brakes, and navigates corners, underscoring the critical importance of maintaining the specified tire pressure.
Finding Your Vehicle’s Recommended Tire Pressure
To discover the ideal tire pressure for your vehicle, you can read our article on How to Check Tire Pressure, or consult the manufacturer-provided placard, which displays the recommended cold tire pressures for both the front and rear tires.
Most commonly, this placard can be found along the driver’s door jamb, but it might also be located inside your glove box or on the inside of the fuel lid. In case you can’t locate the placard, your trusty vehicle owner’s manual almost invariably includes this essential information.
To ascertain your current tire pressure:
- Utilize a tire pressure gauge.
- If your vehicle model is equipped with a digital tire pressure readout on the dashboard, this can provide real-time data.
- For a comprehensive evaluation, consider a visit to an authorized Goodyear dealer to have your tire pressure professionally assessed.
It’s imperative to emphasize that tire pressure checks should be conducted when the tires are cold, meaning the vehicle hasn’t been driven for at least three hours, ideally keeping the tires in a shaded area to avoid temperature-related fluctuations.
One critical point to note is that the sidewall of the tire is not the place to seek guidance for the recommended tire pressure. While you’ll find an inflation pressure listed there, it represents the maximum allowable pressure for the tire, rather than the manufacturer’s suggested level.
The Ramifications of Incorrect Tire Pressure
Using a tire with inadequate inflation pressure, particularly when measured cold, is classified as underinflation. This condition can have adverse effects on vehicle handling, lead to uneven and premature treadwear, increase rolling resistance (thereby affecting fuel economy), and even result in excessive heat buildup, potentially culminating in tire failure.
Conversely, overinflation, wherein a tire’s pressure surpasses the manufacturer’s specifications when cold, can lead to a harsher ride, compromised vehicle handling, increased vulnerability to impact damage, and a potential reduction in wet and dry traction.
The Importance of Regular Tire Pressure Checks
Most modern vehicles, those from the 2007 model year onward, are equipped with a Tire Pressure Monitoring System (TPMS) that alerts you through a dashboard light when a tire is 25% or more underinflated. While this is a critical safety feature, it’s important to remember that tires can become overloaded before reaching the 25% TPMS threshold.
Whether your car features a TPMS or not, Goodyear advises a monthly tire pressure check to ensure your vehicle operates at its best, your tires remain in peak condition, and you maintain optimal fuel economy.
Before embarking on extended road trips, it’s wise to verify your tire pressure, reducing the risk of tire-related issues far from home. Additionally, be aware that temperature fluctuations can affect tire pressure, so periodic checks and adjustments are prudent.
Lastly, don’t forget to inspect the tire pressure in your spare tire. A flat spare is of no use during an emergency. Your vehicle’s placard or owner’s manual will outline the proper spare tire inflation pressure, which often differs from your regular tires.
Addressing Persistent Air Pressure Loss
If your tire consistently loses pressure, it may be indicative of tire or valve stem damage. Continuing to use an underinflated tire can expose it to excessive heat and friction, which might exacerbate the damage. In such cases, consulting a professional for assessment and potential repair or replacement is advisable.
