How do extreme temperature changes affect tire safety?

Minnesota weather swings from 90-degree summers to -30-degree winters, affecting more than just our choice of clothes. Your car tires face real risks during these temperature shifts. When you drive around the Twin Cities in changing weather, your tires need extra attention to keep you safe.  

The science behind tire pressure  

When the temperature drops or rises by 10 degrees, your tire pressure changes by 1-2 PSI. This matters significantly in Minnesota, where temperatures can change by 100 degrees yearly. Cold weather makes tire pressure drop, which leads to:

  • Faster tire wear
  • Bad steering control
  • Higher risk of tire blowouts
  • More gas usage
  • Uneven tire wear  

Spring and fall bring the most significant risks because temperatures often jump up and down within one day.  

Keeping your tires safe in Minnesota weather  

You need to watch your tires closely when seasons change. This becomes even more important if you often drive on busy roads like I-494 or I-35W, where tire problems could cause serious crashes.  

Here’s what you should do:  

  • Check your tire pressure once a month
  • Test pressure when your car sits for 3+ hours
  • Fill tires to the exact PSI your car maker suggests
  • Look for cuts, bulges or odd wear patterns
  • Switch to winter tires when cold weather hits  

Don’t rely only on your car’s tire pressure warning light. It will not turn on until your tires lose 25% of their pressure, and by then, you’ll already be driving on unsafe tires.  

While regular tire maintenance helps prevent most weather-related issues, sometimes tire problems stem from manufacturing defects or improper installation. Suppose you notice unusual tire wear patterns or recurring issues despite proper maintenance. In that case, it’s wise to document these problems and consult with an automotive professional.  

In cases where faulty tires may have contributed to an accident or posed a safety risk, speaking with a qualified attorney can help you understand your options and protect your rights.
