Your tires affect steering, braking, ride comfort, fuel economy, and traction. The best way to care for them is to check their pressure, tread, and condition every month; rotate them according to your vehicle's maintenance schedule; and have alignment or balance concerns inspected promptly.

Tire care is especially important along the Wasatch Front. Bountiful drivers encounter hot pavement, freezing mornings, potholes, road debris, mountain grades, and occasional snow or ice. This guide explains how to maintain your tires through those changing conditions without relying on questionable shortcuts or one-size-fits-all service intervals.

• Check tire pressure and condition at least once a month.
• Use the cold-tire pressure listed on the driver's doorjamb label.
• Measure tread depth in several places across every tire.
• Follow your owner's manual for tire rotation timing and patterns.
• Investigate pulling, vibration, or uneven wear promptly.
• Inspect the spare tire and emergency equipment before road trips.

Check Tire Pressure Every Month

Proper inflation helps a tire support the vehicle's weight and place the intended amount of tread on the road. Underinflation can increase heat buildup, rolling resistance, and shoulder wear. Overinflation can make the ride harsher and contribute to center wear. Either condition can affect handling and tire life.

Check all four tires at least once a month and before a long trip. If your vehicle has an accessible spare, check that tire too. For the most accurate measurement, inspect the tires when they are cold, meaning the vehicle has been parked for at least three hours. Use a reliable gauge and replace each valve cap after checking the pressure.

Use the pressure printed on the Tire and Loading Information label, usually located on the driver's doorjamb. Do not use the maximum pressure molded into the tire's sidewall as your target. That number is a tire limit, not the recommended setting for your vehicle.

Do Not Wait for the TPMS Light

A Tire Pressure Monitoring System, or TPMS, is an important warning feature, but it does not replace manual checks. The warning generally illuminates only after at least one tire has become significantly underinflated. A tire can be below its recommended pressure before the system alerts you.

If the TPMS light comes on, reduce speed if needed, avoid abrupt maneuvers, and check the tires as soon as it is safe. Look for visible damage and measure the pressure rather than judging by appearance alone. If a tire is very low, repeatedly loses air, or has a puncture or sidewall damage, have it inspected before continuing to drive. Bountiful Mazda also has a separate guide explaining what to do when a Mazda tire-pressure light stays on.

Inspect Tread Depth and Tire Condition

Tread channels move water and slush away from the tire's contact area. As tread wears down, a tire has less ability to manage wet or snowy roads. The federal minimum tread depth is 2/32 of an inch, but tires may lose some wet- or winter-weather capability before reaching that limit. Consider your typical driving conditions and ask a tire professional whether earlier replacement would provide a more appropriate safety margin.

A tread-depth gauge provides the clearest measurement. Check several grooves across the inner, center, and outer portions of each tire because wear may not be uniform. You can also use the traditional penny test by placing a penny into a main tread groove with Lincoln's head upside down. If the top of his head remains visible, the tread is at or below approximately 2/32 of an inch in that location.

Tread depth is only part of an inspection. Look for:

• Cuts, cracks, punctures, or exposed cords.
• Bulges, bubbles, or other changes in the sidewall's shape.
• Objects embedded in the tread.
• Flat spots, cupping, edge wear, or unusually rapid wear.
• Persistent pressure loss, vibration, or unusual noise.

Do not drive on a tire with exposed cords, a bulge, or severe damage. Install the spare if it is safe to do so, or request roadside assistance. A professional should determine whether a puncture is repairable because its location, size, and the tire's overall condition all matter. Sidewall damage generally requires replacement.

Rotate Tires at the Correct Interval

Front and rear tires often carry different loads and perform different jobs during acceleration, braking, and cornering. Rotation moves tires between approved positions to help manage those differences and promote more even wear. The correct interval and pattern depend on the vehicle, tire design, drivetrain, and wheel sizes.

NHTSA advises following the owner's manual and notes that, when recommended by the manufacturer, rotations commonly fall within a 5,000- to 8,000-mile range. Some directional or staggered tire setups have limited rotation options, so confirm the correct pattern. If one tire is wearing much faster than the others, rotation alone will not fix the cause.

Know When You Need a Wheel Alignment

Wheel alignment describes the angles at which the wheels meet the road. Those angles can move out of specification after a pothole impact, curb strike, collision, suspension repair, or component wear. Have the alignment inspected if the vehicle pulls on a straight, level road, the steering wheel sits off-center, one edge of a tire wears quickly, or handling changes after an impact.

Pulling can also come from road crown, pressure differences, or a mechanical issue, so it does not automatically prove the alignment is wrong. A technician can inspect the tires, steering, and suspension before recommending an adjustment.

Understand Tire Balancing

Balancing compensates for small weight differences around a tire-and-wheel assembly. Tires should be balanced when installed and may need rebalancing after a repair, a lost wheel weight, or the onset of vibration. Because vibration can also come from tire damage, a bent wheel, or worn suspension parts, diagnosis is more useful than balancing at an arbitrary mileage.

Prepare Tires for Utah's Changing Seasons

Air pressure changes as outdoor temperatures rise and fall, which is why a TPMS light may first appear on a cold morning. Check cold pressure more frequently during major seasonal shifts and adjust it to the doorjamb specification. Do not intentionally overinflate tires in anticipation of colder weather.

All-season tires handle a range of everyday conditions, but dedicated winter tires are generally better suited to sustained cold, snow, and ice. Summer tires are not intended for freezing temperatures or winter precipitation. Choose the appropriate type and size for all wheel positions, and store off-season tires in a cool, dry place away from direct sunlight and chemicals.

Check Tire Age and the DOT Code

Tires age even when they retain plenty of tread. Heat, sunlight, storage, maintenance, and use all influence that process. There is no single replacement age for every tire, so follow the recommendations from the vehicle manufacturer and tire maker.

You can identify a tire's manufacturing date through its DOT Tire Identification Number. The final four digits represent the week and year of manufacture. For example, a code ending in 2324 indicates production during the 23rd week of 2024. The complete code may appear on only one sidewall, so the inward-facing side may need to be inspected.

NHTSA notes that some manufacturers recommend replacement within a six- to 10-year range regardless of tread. A visual check cannot guarantee that an older tire is safe, so have aging tires professionally inspected and follow the applicable manufacturer guidance.

Do Not Forget the Spare Tire

Check the spare's pressure, condition, and age before road trips. Temporary spares often require a different pressure and have strict speed and distance limits. Also confirm that the jack, lug wrench, wheel-lock key, or inflator kit is present and usable. Sealant cartridges can expire, and some vehicles use an inflator kit instead of a spare.

Use the Correct Replacement Tires

Replacement tires should meet the size, load, speed, and performance requirements specified for the vehicle. Mixing substantially different tread patterns, wear levels, constructions, or sizes can affect handling. Matching is particularly important on all-wheel-drive vehicles, where allowable differences in circumference or tread depth may be limited. Do not replace only one tire without measuring the others and reviewing Mazda's requirements.

The Bountiful Mazda tire center can help identify tires that match your Mazda and the conditions you encounter around Bountiful, Salt Lake City, and northern Utah.

Does Nitrogen Make Tires Maintenance-Free?

No. Nitrogen may allow pressure to change more slowly in some situations, but it does not eliminate normal pressure loss, punctures, valve leaks, or seasonal changes. Air is already mostly nitrogen, and the most important factor is maintaining the correct cold inflation pressure. Tires filled with nitrogen still need monthly checks and can be topped up with regular compressed air when necessary.

Frequently Asked Questions About Tire Care

How often should I check tire pressure?

Check every tire, including an accessible spare, at least once a month and before long trips. Measure pressure when the tires are cold and use the specification on the driver's doorjamb label.

How often should tires be rotated?

Follow the interval and pattern in your owner's manual. When the manufacturer recommends rotation, NHTSA identifies 5,000 to 8,000 miles as a common general range, but your vehicle or tire setup may require different guidance.

When should tires be replaced?

Replace a tire when tread reaches 2/32 of an inch, when it has unrepairable damage, or when age and manufacturer guidance call for replacement. Earlier replacement may be sensible when additional wet- or winter-weather traction is needed.

Why is my tire wearing unevenly?

Possible causes include incorrect pressure, misalignment, imbalance, worn suspension components, skipped rotations, or a tire or wheel problem. The wear pattern should be diagnosed before new tires are installed.

Can I replace only one tire on an AWD Mazda?

Sometimes, but only if the remaining tires and the replacement meet Mazda's allowable specifications for size and tread-depth difference. A technician should measure all four tires and consult the requirements for your exact model.
