(Feature Impact) As drivers prepare for summer road trips, navigating seasonal weather with worn tires can often be an overlooked safety concern. For those living in regions that experience seasonal storms and heavy rainfall, ensuring their vehicle’s tires are properly maintained can mean the difference between stopping safely or being involved in an accident.
As tread depth decreases, tires’ ability to maintain grip on wet pavement diminishes, increasing both stopping distances and the likelihood of losing control. In fact, on roads with light rain is where the Federal Highway Administration reports 77% of weather-related crashes occur.
New testing revealed worn tires (approximately 4/32-inch tread depth) required 30-45% more stopping distance – equating to 44-67 additional feet, depending on the tire model – to bring an average car or sedan to a full stop when braking. During moderate and heavy rainfall, vehicles equipped with worn tires required more than 140 additional feet to stop – nearly half the length of a football field. This data comes from water depth stopping-distance testing performed from 60 miles per hour at Treadwell Research Park on behalf of Discount Tire, a leading independent retailer of tires and wheels with more than 1,275 stores in 40 states.
Summer weather can be unpredictable and with the chance of sudden storms expected this time of year, drivers should take extra precautions to ensure their tires can stop safely in wet conditions.
Drivers can use tools like Treadwell, Discount Tire’s online tire recommendation tool, to compare stopping distances of popular tire models in new and worn conditions. The tool evaluates tire options based on vehicle type, driving habits and local conditions – as well as decades of data and independent testing results – to provide recommendations based on each driver’s unique needs.
Before hitting the road, consider these expert tips:
Monitor Tire Tread Depth
Tread depth plays a critical role in wet-weather traction and stopping performance. Drivers can perform a quick tread check at home using a penny. Insert the penny upside down into a tread groove; if the top of President Lincoln’s head is visible, it’s time to replace the tire. If you’re not sure, head to a local tire retailer to have them check for you.
Know the Tires’ Age
As rubber compounds age, the rubber becomes harder and more susceptible to cracking and failure. To check a tire’s age at home, look at the DOT number stamped on its sidewall. Experts typically recommend replacing tires that are 6 years old or older, depending on condition and manufacturer guidance.
Rotate Tires on Schedule
Tires should be rotated every 6,000 miles, or earlier if uneven wear develops. Routine tire rotations help promote even wear and maximize tire life.
Check Tire Pressure Regularly
Tire pressure should be checked at least once a month when tires are cool, particularly before any long road trips, because ambient temperature changes as well as the impacts and pressures of bumps and turns can affect inflation levels. Underinflated tires can contribute to poor handling, excessive wear, reduced fuel efficiency and increased stress on the tires due to overloading.
