The Right Tire Pressure: Maximum vs. Recommended

It’s common knowledge for vehicle owners to keep an eye on their tires– slow leaks and flats are some of the most typical problems to experience on the road. While there is often an easy fix, not every driver knows the proper way to keep their tires inflated. Left unchecked these issues can lead to poor performance and even dangerous driving conditions! Park Muffler is here to set the record straight on tire pressure, so read on for our detailed guide.

PSI/KPA

Pounds per square inch (psi) and kilopascals (kPa) are simply different units used for pressure. Both are commonly printed on tires and in owner’s manuals, but they are equal measurements for the same amount.

Maximum Tire Pressure

Maximum tire pressure is commonly misinterpreted as the correct tire pressure– that’s not always the case! It’s easy to see why the mistake is made: maximum pressure is printed on the sidewall of your tires. You may have seen these numbers when filling or topping up a tire with pressurized air. While you should never exceed the maximum pressure rating, you should always consult your vehicle’s owner’s manual for the recommended or optimal tire pressure.21

Recommended/Optimal Tire Pressure

Usually found in the owner’s manual, your vehicle’s recommended or optimal tire pressure may also be listed inside the fuel door, trunk lid, glove compartment or even the edge of a doorframe. Your vehicle’s manufacturer calculates this number after collecting data from rigorous safety, durability and efficiency testing. Inflating above the recommended pressure can result in poor handling and shortened tires life; letting your tires drop below optimal pressure can result in increased wear and decreased fuel efficiency.

Tips & Tricks

Your tires may be under- or overinflated and may show no visible signs! Keep a pressure gauge in your vehicle and check your tires regularly against the manufacturer’s recommended or optimal guidelines. Familiarize yourself with your vehicle’s warning lights and respond promptly to any changes in handling, mileage or tire wear.
