Key Takeaways

1. Winter freeze thaw cycles create pothole conditions across Nashville roads that place real stress on suspension components and wheels.
2. Hitting a pothole at speed can cause damage that isn't always obvious right away.
3. A few driving habits reduce the risk of suspension and wheel damage during the roughest months.
4. Post pothole inspections catch hidden issues before they turn into bigger repairs.

Every winter and into early spring, Nashville's roads develop their share of potholes as freeze thaw cycles take their toll on pavement across the city. A quick suspension check after hitting a bad pothole costs far less than repairing damage that went unnoticed for months. A little awareness of how potholes affect a Forester helps drivers protect their vehicle through the roughest stretches of the year.

Why Nashville Sees a Pothole Season

Nashville's winters bring enough freeze and thaw cycles to create real pothole conditions, even though the city doesn't see the sustained deep freeze of colder climates. Water seeps into small cracks in the pavement, freezes and expands overnight, then thaws again during the day, gradually widening those cracks until a section of road gives way under traffic. Routes like Ellington Parkway, Dickerson Pike, and stretches of I-24 tend to develop noticeable potholes during the worst of this cycle, and they often appear with little warning after a hard freeze.

How Potholes Affect Suspension Components

Hitting a pothole at speed sends a sudden, sharp impact through the wheel and into the suspension system, and that impact can affect several components at once. Shocks and struts absorb the initial jolt, but a hard enough hit can damage their internal seals or valving. Control arm bushings and ball joints can also be stressed beyond their normal range, sometimes without any immediately obvious symptom. The severity of the impact often depends on speed, the depth and shape of the pothole, and whether the driver has any chance to slow down before hitting it.

Because damage from a single hard impact doesn't always cause an immediate, obvious symptom, a Forester can be driven for weeks afterward before a driver notices something feels different in the ride.

Wheel and Tire Damage from Potholes

Wheels take just as much of the impact as the suspension, and potholes are a common cause of bent rims, sidewall damage, or a sudden loss of tire pressure. A sharp edged pothole can crack a wheel or cause a bulge in the tire's sidewall, both of which compromise the tire's structural integrity even if the vehicle seems to drive normally afterward. A bent wheel can also throw off alignment, leading to uneven tire wear that develops gradually over the following weeks.

Driving Habits That Reduce Pothole Risk

A few habits help reduce the chances of significant damage when a pothole can't be avoided:

1. Maintaining proper following distance, which gives a driver more time to spot a pothole and react before hitting it directly
2. Slowing down rather than braking hard directly over a pothole, since braking shifts weight forward and can increase the force of impact on the front suspension
3. Keeping tires properly inflated, since correctly inflated tires absorb impact somewhat better than underinflated ones, which are more prone to sidewall damage

Signs Your Forester May Have Pothole Damage

A few symptoms are worth having checked after hitting a significant pothole, even if the vehicle seems to drive normally at first:

1. A pulling sensation to one side while driving
2. Vibration through the steering wheel at highway speeds
3. A noticeable change in ride quality, such as increased bouncing over small bumps
4. Visible damage to a wheel, such as a crack, dent, or bulge in the tire sidewall

"After a hard freeze we always see an uptick in customers coming in after hitting something they didn't see in time," says our technician Rodrigo Estes. "A quick alignment and suspension check after a bad pothole hit usually catches anything before it turns into a bigger repair down the road."

Building Pothole Awareness Into Regular Driving

Our service advisor Latoya Sanders recommends that Forester owners have their vehicle checked any time they hit a pothole hard enough to notice the impact in the cabin, rather than waiting to see if a symptom develops. Because some suspension and wheel damage doesn't announce itself right away, a quick inspection after a rough hit often catches something before it becomes a larger repair or a safety concern down the road.

Nashville's pothole season is simply part of driving in this city through the winter and early spring months, and a bit of awareness helps keep a Forester's suspension and wheels protected through the roughest stretches of road. Our team at Nashville Subaru, located at 1406 Brick Church Pike, Nashville, TN 37207 is happy to check your suspension and wheels after a rough pothole encounter or as part of routine seasonal maintenance.
