A recent report found that many drivers ignore the tire pressure monitoring system (TPMS) warning light in their vehicles, which can lead to premature tire wear and the need to replace tires sooner than necessary. Properly inflating tires to the recommended PSI can extend their lifespan by thousands of miles, but 45% of drivers surveyed didn't know where to find the correct tire pressure information.

Why it matters

Tire costs have been steadily rising, with the average set of four tires costing $848 according to a recent survey. Ignoring the TPMS warning light can lead to under- or over-inflated tires, which wear down faster and require more frequent and costly replacements. Maintaining proper tire pressure is an easy way for drivers to save money and extend the life of their tires.

The details

The TPMS warning light can turn on when cold weather causes the air pressure inside tires to drop. However, a survey found that 5% of drivers admitted to ignoring the warning light entirely. Properly inflated tires can last 4,700 miles longer before needing replacement. The report also found that 86% of tire buyers didn't negotiate the price, but those who did were able to save a median of $37 per tire, with some saving $100 or more.

The takeaway

Ignoring the TPMS warning light can lead to significant costs down the road, as under- or over-inflated tires wear out much faster. Taking the time to properly inflate tires to the recommended PSI can save drivers hundreds of dollars by extending the life of their tires. Additionally, negotiating tire prices can lead to substantial savings, with some buyers reporting savings of $100 or more per tire.
