Tucson residents know that summer isn't just a season; it's an endurance test for your vehicle. While most people associate roadside emergencies with the freeway, the Arizona heat is actually the primary reason tires fail on city streets like Grant Road or Campbell Avenue. Intense pavement temperatures cause the air inside your tires to expand rapidly, leading to increased pressure and a higher risk of a sudden blowout.
WARNING SIGNS TO WATCH FOR
- The Pressure Warning: If your TPMS light flickers on a hot afternoon, your tires are likely overheating and over-expanding.
- Visible "Dry Rot": Intense UV rays in Tucson cause tires to crack. If you see tiny spider-web cracks in the sidewall, the rubber is failing.
- Sidewall Bulges: Never ignore a bubble or bulge on the side of your tire. This indicates internal structural failure and an imminent blowout.
- Vibration or Thumping: If your car starts shaking while driving on the I-10, your tread may be starting to separate from the tire carcass.
- The 6-Year Rule: In Tucson, most tires only survive about 5 to 6 years before the sun makes them unsafe. If your tires are older, an emergency flat is in your future.
To keep your tires healthy, try to park in shaded areas like the University of Arizona parking garages or under residential carports. Regularly check your tire pressure while the rubber is "cold" to ensure you have a solid and safe connection to the road.
