A winter of freeze, thaw and patched blacktop leaves its mark on tires and steering. This is what to look for this spring, and when a quick check can save a set of tires.
By March, everybody in St. Francois County has a mental map of the worst potholes. There's the one by the stoplight you can't swerve around. There's the washboard stretch on the county road home, and the patch that sank again after the last freeze. Your tires and suspension took every one of those hits.
Usually a pothole leaves you with a jolt and a bad word. Sometimes, though, it nudges the wheels out of alignment or bruises a tire, and you don't see the damage until it's worn in over the next few thousand miles. Spring's the time to look, before a small problem eats a set of tires.
Quick answer: A hard pothole hit can knock the alignment off or damage a tire. Watch for a pull to one side, an off center steering wheel, vibration or uneven tread wear. Ford recommends rotating tires at every oil change and checking pressure monthly, and spring's big temperature swings make that monthly check count.

Why Is Spring Pothole Season Hard on Tires and Alignment?
Water gets into cracks in the road, freezes, expands and then thaws. That leaves a weak spot, and traffic breaks it open. Cold snaps followed by warm afternoons run that cycle over and over all winter, so the roads look their worst in early spring.
Drop a tire into one at speed and the force goes straight through the wheel into the suspension and steering. Hit it hard enough and you can shift the alignment or bend a wheel. It can also pinch the tire against the rim and hurt the sidewall from the inside.
Gravel county roads are their own kind of hard. Loose rock and washboard ruts chew at tread and shake suspension parts every day. A truck that lives on gravel needs a closer eye than one that stays on pavement.

What Are the Signs Your Ford Is Out of Alignment?
Alignment trouble tends to creep up on you. After a rough stretch of road, watch for these:
Get these checked soon
Pulling to one side. On a flat, straight road, your Ford drifts left or right when you ease off the wheel.
Off center steering wheel. The wheel sits crooked while you drive straight ahead, even if the truck tracks fine.
Vibration at speed. A shake through the steering wheel can mean a bent wheel, a tire problem or balance. Have it looked at.
A bulge or bubble on the sidewall. That points to internal tire damage. Replace the tire before it fails, especially before highway driving.
Uneven or fast tread wear. One edge wearing faster than the other is a classic alignment clue.
If you hit something hard enough to wince, ask for an alignment check next time you book. Catching it early saves the tires you already paid for.
What Do Uneven Tire Wear Patterns Tell You?
Your tread keeps a record of how the truck's been treated. Run a hand across it and look close at the edges:
- Inner or outer edge worn down: usually a camber issue, meaning the wheel leans inward or outward instead of standing straight.
- Feathered tread: ribs that feel smooth one way and sharp the other often point to a toe problem.
- Center worn more than the edges: a sign the tire has been run overinflated.
- Both edges worn more than the center: a sign of running underinflated.
- Cupped or scalloped spots: can point to worn suspension parts or balance trouble.
If one tire's wearing oddly and the rest look fine, the problem's usually at that corner. A technician can measure tread depth across each tire and tell you what fixes it.

Why Does Tire Pressure Swing So Much in Spring?
Air shrinks when it cools and expands when it warms. Goodyear puts it at roughly 1 to 2 PSI for every 10 degree drop. A Missouri spring morning in the 30s can turn into an afternoon in the 70s, so pressure you set on a warm day can read low the next cold morning.
That's why the tire pressure light likes to pop on during a chilly start and go out a few miles later. Don't ignore it anyway. Low pressure wears the shoulders and costs you fuel economy. It also makes a tire easier for a pothole to damage.
Set pressure to the number on the label inside the driver door jamb, not the maximum printed on the sidewall. Check it cold, before you drive. Ford recommends once a month.
Park Hills driver tip
If you pull a loaded trailer to the lake one weekend and drive empty the next, look up the load related pressure guidance in your Owner's Manual. If your truck goes back and forth between heavy loads and empty commutes on US 67, run a gauge over the tires before each trip.

How Often Should You Rotate Ford Tires?
Ford keeps it simple. Rotate the tires every time you get the oil changed. On most vehicles the fronts do the steering and carry more weight, so they wear differently than the rears. Swapping them around evens that out, and the whole set lasts longer.
It's also a chance for the technician to catch a nail in the tread or a damaged sidewall early. If your Ford spends a lot of time on gravel, stick to that schedule.
You don't even have to come in for it. Ford Mobile Service handles tire rotations at your home or work, depending on distance and availability. Book through the dealer, the FordPass app, or by calling 573-430-1693.
When Is It Time for New Tires?
Tires don't wait for a convenient month. The usual signs a set is done:
- Tread at the wear bars: small raised bars molded into the grooves sit at 2/32 inch. When the tread is flush with them, the tire is worn out.
- Poor wet traction: spring storms find worn tires fast. If your Ford slides more than it used to in the rain, the tread may be shallower than it looks.
- Sidewall damage: cuts, bulges or cracking from age or a hard pothole hit.
- Uneven wear past saving: once a tire's worn badly on one edge, an alignment won't bring that tread back.
When it's time, tell the service team how you drive. Highway commuting toward St. Louis calls for a different tire than gravel and mud around the farm. Get an alignment check with the new set so they wear evenly from day one.

Potholes and Damage
Can one pothole knock my Ford out of alignment?
A hard enough hit can shift alignment angles, bend a wheel or damage a tire. If the steering feels different afterward, get it checked.
How do I know if a pothole damaged my tire?
Look for a bulge on the sidewall, a cut, or a slow loss of pressure. Any sidewall bulge means the tire should be replaced.
Are gravel roads hard on tires?
Loose rock and washboard ruts wear tread and stress suspension parts, so trucks that live on gravel benefit from regular rotations and inspections.
Alignment
What are the signs I need an alignment?
Pulling to one side, an off center steering wheel and uneven tread wear are the most common signs.
How often should alignment be checked?
Tire makers suggest a check at least once a year, after a hard impact, and whenever new tires go on.
Does a crooked steering wheel always mean bad alignment?
Usually, though worn steering or suspension parts can cause it too. A technician can tell which one it is.
Tire Pressure
Why does my tire pressure light come on when it is cold?
Cold air takes up less space, so pressure drops overnight. The light may go out once the tires warm up, but check and adjust them anyway.
What pressure should my Ford tires be?
Use the pressure listed on the label inside the driver door jamb, measured when the tires are cold.
How often should I check tire pressure?
Ford recommends a monthly check, and spring temperature swings make that habit more important.
Rotation and Replacement
How often should Ford tires be rotated?
Ford says to rotate them every time you get an oil change, which keeps wear even across all four.
When should I replace my tires?
Replace them when the tread reaches the wear bars, when wet traction fades, or when the sidewall is damaged.
Can I replace just one tire?
Sometimes, depending on how worn the others are and whether your Ford has four wheel or all wheel drive. Ask the service team before buying a single tire.
Scheduling and Convenience
Can Ford Mobile Service rotate my tires at home?
Tire rotation is on the Mobile Service list, depending on distance and availability. Book through the dealer or the FordPass app.
