Ottawa pothole season: what that bang actually did to your car
A hard pothole hit in Ottawa most often damages a tire sidewall first, then a bent rim, a knocked out alignment, a bent control arm, or a blown strut, roughly in that order of likelihood. A flat tire or a loud clunk means stop and check it now. A pull to one side or a faint vibration can usually wait a few days for an appointment.
What a pothole hit actually breaks, in order
Ottawa’s freeze and thaw cycle through March and April opens up potholes across the city faster than crews can patch them, and a hard hit at speed can damage several parts of your car at once. Not every hit causes the same damage, and the parts break down roughly in this order of how often we see them after a bad hit.
Tire sidewall. This is the most common casualty. The sidewall is the thinnest, least reinforced part of the tire, and a sharp edged pothole can pinch or tear it against the rim on impact. Damage here can be invisible from the outside while the tire is still weakened internally.
Bent rim. The wheel itself can bend or dent from a hard enough hit, especially on lower profile tires that give the rim less cushioning from the tire’s sidewall.
Knocked out alignment. A jolt through the suspension can shift the angles the wheels sit at, even without breaking any single part. This is the most common outcome overall, and often the least obvious right away.
Bent control arm. The control arm connects the wheel assembly to the car’s frame and can bend under a hard enough impact, which throws off both handling and alignment.
Blown strut. Struts absorb the shock of the impact, and a severe enough hit can damage the strut itself, which shows up as a much rougher, bouncier ride afterward.
Symptoms to watch for, and what they usually mean
A flat tire or visible bulge in the sidewall right after the hit means the tire is done, do not drive on it. A bulge is the rubber and internal cords already failing, and it can blow out without warning.
A vibration through the steering wheel or seat, especially one that gets worse at highway speed, points to a bent rim thrown out of round, or in some cases a wheel that is no longer balanced from the impact.
A pull to one side, where the car drifts left or right when you take your hands lightly off the wheel, is the classic sign of a knocked out alignment. It is uncomfortable and wears your tires unevenly over time but is not usually an emergency on its own.
A clunking or knocking noise over bumps, especially if it continues well after the original pothole hit, suggests a bent control arm or a loose or damaged suspension component. This one is worth getting checked sooner rather than later, since a compromised control arm affects how the wheel stays connected to the car.
Excessive bouncing, a noticeably rougher ride, or the car feeling loose through turns after a hit points toward a damaged strut. Struts do not usually fail instantly and completely, they degrade, and a hard pothole hit can accelerate that.
When to get it looked at immediately versus when it can wait
Stop driving and get the car checked right away if you have a flat tire, a bulging sidewall, a loud clunk that continues after the hit, a wheel that looks visibly crooked when you look at it from in front of the car, or a pull strong enough that you have to fight the wheel to keep the car straight. Any of those point to damage that can get worse quickly or affect how the car handles.
A mild pull, a faint vibration you only notice at highway speed, or uneven tire wear you spot later can usually wait a few days for a normal appointment. It is still worth getting checked, because driving for weeks on a knocked out alignment wears tires unevenly and can eventually stress other suspension parts, turning a simple alignment into a bigger repair.
What we check after a pothole hit
We inspect the tire and rim first, since those are the most common and the easiest to confirm visually and by feel. From there we check alignment, and if the symptoms point to it, we inspect the control arms, bushings, and struts for play, bending, or leaking. A hands on inspection is really the only way to confirm what a single hit did, since several of these problems produce overlapping symptoms.
Why pothole season hits Ottawa harder than most cities
Ottawa’s climate is part of the problem. Water gets into small cracks in the pavement, freezes overnight, and expands, widening the crack. As temperatures swing above and below freezing repeatedly through March and April, that cycle repeats over and over on the same stretch of road, and pavement that looked fine in February can open into a real pothole within a couple of weeks once the thaw sets in properly.
That is also why the worst potholes tend to appear on the same problem stretches of road every single spring, often on routes with heavier truck and bus traffic, since the added weight accelerates the same freeze and thaw damage. If you drive a regular commute, it is worth watching for the spots that were bad last spring, since they are likely candidates again.
A word on driving through pothole season itself
Slowing down over a rough stretch of road and keeping a bit more following distance gives you time to see and avoid the worst potholes rather than hitting them at full speed. It will not eliminate the risk entirely, since some potholes are genuinely hard to see, especially in low light or when a puddle is hiding the depth of the hole underneath, but it reduces both how often you hit one and how hard the impact is when you do.

Common questions
I hit a pothole and now my car pulls to one side, is that serious?
A pull to one side after a pothole hit usually means the impact knocked your wheel alignment out of position. It will not strand you, but driving on it for weeks wears your tires unevenly and can stress other suspension parts, so it is worth booking an alignment check within a week or two rather than ignoring it.
What does a bent rim feel like when I am driving?
The most common sign is a steady vibration through the steering wheel or the seat that gets worse at highway speed, sometimes along with a faint thumping sound in rhythm with the wheel's rotation. A visibly dented or out of round rim on inspection confirms it.
How do I know if a pothole bent a control arm or damaged a strut?
A bent control arm often shows up as uneven tire wear, a clunking noise over bumps, or the car pulling noticeably to one side even after an alignment. A damaged strut usually causes excessive bouncing after a bump, a knocking sound, or the car feeling loose and less controlled through turns. Both need a hands on inspection to confirm.
Should I drive on a tire that took a hard pothole hit, even if it still looks fine?
A sidewall can be weakened internally without any visible damage on the outside, and a weakened sidewall can fail suddenly, especially at highway speed. If the hit was hard enough to hear a bang or feel a jolt through the cabin, have the tire inspected before driving on it much further.
When is a pothole hit an emergency versus something that can wait?
A flat tire, a loud clunk that continues after the hit, a wheel that looks visibly crooked, or a car that suddenly pulls hard to one side all mean stop driving and get it checked right away. A mild pull, a faint vibration, or slightly uneven tire wear noticed later can usually wait a few days for a normal appointment.
