Pothole Season: Why St. Louis Winters Are Brutal on Your Tires and Suspension
St. Louis winters bring a real freeze-thaw cycle that is brutal on pavement, and pothole season here tends to be worse than in places with more consistently cold or consistently mild winters.
Why the Freeze-Thaw Cycle Is So Damaging
Water seeps into small cracks in the pavement, freezes and expands overnight, then thaws again the next day — repeated dozens of times over a winter, this cycle turns small cracks into real potholes fast. St. Louis’s winter pattern of freezing nights and warmer days makes this cycle especially active compared to climates that just stay cold.
What a Bad Pothole Hit Can Actually Damage
- Bent wheels or rims, especially on larger, lower-profile tires
- Tire sidewall damage that is not always visible right away
- Suspension components, alignment, and in worse cases steering damage
What to Do After a Hard Hit
If the car pulls to one side, makes new noise, or the ride feels different after hitting a pothole hard, get it inspected rather than assuming it is fine because it still drives. A wheel or alignment issue left unaddressed tends to get more expensive, not less, the longer it is driven on.
