Why is tire maintenance important?

Tires are durable, but they're also the only part of the car actually touching the road. Every braking event, turn, and acceleration load goes through four contact patches roughly the size of a hand. The conditions those patches encounter — pressure changes, temperature swings, load variations, road surface — affect how the tire wears and performs. Maintenance doesn't extend tire life beyond what the tire was designed for; it makes sure the tire reaches that design limit instead of falling short of it.

A tire at the wrong pressure behaves differently than one at spec. Underinflated tires run hotter because the sidewall flexes more with every rotation, which accelerates internal degradation and raises the risk of failure, particularly at highway speeds. Overinflated tires reduce the contact patch, which affects traction and makes the vehicle more sensitive to road irregularities. Both conditions also accelerate wear — underinflation on the outer edges, overinflation in the center.

It does. Tires in good condition stop shorter, handle more predictably, and resist hydroplaning better than worn or under maintained ones. The difference is most pronounced in wet weather, where tread depth and correct inflation pressure determine whether the tire channels water effectively or rides up on a film of it. Proper alignment keeps the tires tracking straight, which matters most in emergency lane changes and sudden braking.

A tire that consistently runs low on pressure wears faster on both outer edges and runs at a higher operating temperature than it was designed for. Over time, that heat accelerates breakdown of the internal structure and increases the risk of sudden failure, especially under load or at speed. The tire may also look normal on the outside while internal damage has already occurred. Beyond the safety concern, an underinflated tire also hurts fuel economy through increased rolling resistance.

Yes. A newer vehicle with low mileage still loses tire pressure naturally over time — tires seep air slowly regardless of age. New tires can also arrive misaligned, suffer impact damage from the first pothole, or wear unevenly if the vehicle is driven primarily on one type of road. Age and mileage are not a substitute for regular checks.

Alignment refers to the angles at which the tires sit relative to each other and the road. When those angles are off, the tires scrub against the pavement at a slight angle with every rotation rather than rolling cleanly. That scrubbing wears the tread unevenly and faster than it should. A vehicle with poor alignment can go through tires well before their expected life, and the driver may not notice until the damage is already significant.
