When summer heat hits Saginaw, Freeland, and Bridgeport, MI, it brings more than just sun and road trips—it also brings shifting road conditions that can take a toll on your tires. While proper tire inflation is important year-round, it becomes especially critical during the warmer months. The combination of rising temperatures and long drives increases the risk of tire problems if your inflation levels aren’t dialed in just right.
Heat Causes Tire Pressure to Fluctuate
Tire pressure naturally rises as the temperature outside increases. For every 10°F rise in ambient temperature, your tire pressure can increase by about 1 PSI. If your tires are already close to their maximum limit, the added pressure from hot summer weather can push them over, leading to overinflation. Overinflated tires wear unevenly, reduce traction, and may be more prone to blowouts—especially on long highway trips.
Underinflation Is Just as Risky
While overinflation gets a lot of attention, underinflated tires are just as dangerous. When tires are underinflated, they generate more heat due to increased rolling resistance. This can cause premature tread wear and weaken the tire’s structure from the inside out. An underinflated tire on a hot road surface is a recipe for failure, particularly during sudden stops or sharp turns.
Effects on Safety and Fuel Economy
Improperly inflated tires don’t just wear out faster—they also compromise your safety. Poor inflation can affect braking distance, cornering stability, and overall handling. Additionally, both over- and underinflation negatively impact fuel efficiency, costing you more at the pump. For drivers in Saginaw, Freeland, and Bridgeport, proper inflation is a simple step toward better performance and safer driving in summer conditions.
Check Pressure Regularly and Use Manufacturer Specs
The best way to maintain proper inflation is by checking your tire pressure at least once a month—ideally when the tires are cool. Use a reliable gauge and refer to the PSI recommended on the sticker inside your driver’s door, not the number printed on the tire sidewall. A local auto repair shop can also inspect for slow leaks, tread wear, or damage that might not be obvious at a glance.
Final Thoughts
Hot weather and improper tire pressure are a dangerous combination. For drivers across mid-Michigan, keeping tires properly inflated helps ensure longer tread life, better handling, and safer summer driving. A quick pressure check today could prevent a big problem tomorrow.
