If your Santa Fe's tires are wearing unevenly, shaking at highway speed or showing cracks on the sidewall, it's time to replace them. Do it before the potholes really open up, because worn tires take a hard hit badly. At Riverhead Hyundai, we hear a lot of tire questions from Riverhead drivers once fall turns cold. Here's how to spot each sign and what to do about it.
Why Worn Tires and Potholes Don't Mix
A pothole hits a tire hardest in one spot. When you drop into one, the sidewall gets pinched between your wheel rim and the broken edge of the pavement. A healthy tire with good tread and proper air pressure has enough rubber and air to absorb that blow. A worn or aging tire has less cushion, so the same hit is more likely to leave you with a bulge, a bent wheel or an alignment that's knocked out of whack.
Riverhead roads take a beating once the weather turns. Water seeps into cracks on Route 58 and the back roads off Sound Avenue, freezes overnight, and pops the asphalt loose. By the time road crews patch them, you've probably already rolled over a few fresh ones.
Your Santa Fe is a midsize SUV, so it puts more weight on each tire than a small sedan does when it drops into a hole. That's why it pays to check your tires before the rough season, not after your first flat. Start with tread depth, then go through the three warning signs below.
Start Here: Checking Tread Depth
Before you look for the three signs, get a baseline. Tread depth tells you how much grip and water-clearing ability your tires have left, and you can check it in your driveway in about five minutes.
The coin test
- Slide a penny into the shallowest groove with Lincoln's head pointing down. If you can see the top of his head, you're at or near 2/32 of an inch, the legal minimum in New York.
- Try a quarter the same way. If Washington's whole head shows, you're under about 4/32, and wet-road grip drops off noticeably below that point.
- Test the inside, middle and outside grooves on all four tires. They don't always wear the same.
Wear bars
Look for small raised bars running across the bottom of the grooves. Once the tread wears down flush with them, that tire is finished.
Fall here means wet leaves and steady rain on Route 25, and shallow tread can't push water out of the way fast enough. If the quarter test is already showing Washington's head, start planning for new tires now instead of waiting for one of the signs to show up.
Sign #1: Uneven Tread Wear
Run your hand across the tread of each tire, then crouch down and look at it from the front. You want to see about the same depth from edge to edge. Here's what the common patterns usually mean:
- Worn on both outer edges: the tire has been running low on air.
- Worn down the center: usually too much air.
- Worn on one edge only: the alignment is probably off, often from a curb or pothole hit.
- Scalloped dips, or cupping: worn shocks or struts, or a tire that's out of balance.
What it means for you
Uneven wear eats tread faster in one spot. A tire can look fine from the outside and be nearly bald on the inside edge, where you won't notice it unless you look. That thin spot has the least cushion when you hit a hole.
What to do
Fix the cause and the tire together. If you put on a new tire without correcting the alignment or air pressure, the new one will wear out the same way. When the wear is mild, a rotation and alignment may buy you more time. If one edge is down near the wear bars, it's time for new tires.
Sign #2: Vibration and Alignment Clues
You'll usually feel this one before you see it. A shimmy in the steering wheel or a buzz through your seat once you get up to speed on the Long Island Expressway is your tires or wheels telling you something's wrong.
What it means
- Vibration you feel in the steering wheel often points to the front tires or wheels.
- If you feel it in the seat or floor, it's more likely coming from the rear.
- A pull to one side, or a steering wheel that sits crooked while you're driving straight, points to alignment.
- A shake that started right after a pothole could mean a bent wheel or damage inside the tire.
A wheel that lost a balance weight is a quick fix. A tire with a shifted belt inside is different, and it won't get better on its own. Vibration that gets worse as you speed up deserves a look soon.
What to do
Don't just turn up the radio and live with it. Have the tires balanced and inspected, and get an alignment check, especially if you've hit something hard recently. Catching a bad alignment early also saves the tread you still have, since a misaligned wheel keeps scrubbing rubber off one edge every mile you drive.
Sign #3: Cracks and Bulges on the Sidewall
Tread gets most of the attention, but the sidewall is what takes the hit when you drop into a pothole. Walk around your Santa Fe and look closely at the side of each tire, from the rim up to the tread.
What to look for
- Fine cracks or a crazed pattern in the rubber, which come with age and sun exposure
- A bubble or bulge, which means the cords inside are damaged and air is pushing against the outer rubber
- Cuts, gouges or missing chunks from scraping a curb
What it means
Cracks tell you the rubber is drying out and losing flexibility, even if the tread still looks deep. A bulge is far more serious. That tire can fail without warning, and a hard pothole hit is just the kind of thing that finishes it off.
Check the tire's age while you're down there. Find the DOT code on the sidewall; the last four digits show the week and year the tire was made. Rubber hardens over time no matter how few miles you drive.
What to do
If you see a bulge, replace that tire now, and drive on the spare until you can. Light surface cracking is worth having someone look at before the roads get rough.
Getting Through Pothole Season in One Piece
New tires or not, a few habits help your Santa Fe make it to spring without a bent wheel or a surprise flat.
- Check pressure once a month. Cold mornings lower tire pressure, and an underinflated tire is much easier to damage. Use the pressure on the sticker inside the driver's door, not the maximum molded into the sidewall.
- Leave following room. If you're tailgating, you won't see the hole until you're in it.
- Slow down before the hole, not in it. Brake ahead of time, then ease off the pedal as you roll through so the suspension can absorb the hit.
- Be wary of puddles. On Sound Avenue and the farm roads, standing water can hide a deep one.
- Take your tire pressure light seriously. If it comes on after a hit, pull over somewhere safe and check.
After a hard hit, walk around the vehicle at your next stop. Look for a bulge, a dented rim edge, or a tire that sits lower than the others. Spotting damage in a parking lot is much better than finding it with a blowout on Route 58 during rush hour.
When to Schedule a Tire Appointment
If you found any of the three signs, or the coin test came up short, don't wait for the first big storm. Book a tire check while the roads are still in decent shape, so you aren't stuck on the shoulder waiting for a tow.
What a good tire visit covers

- A bulge on the sidewall means replace that tire now, and fall is the right time for a full tire check.
FAQ Common questionsHow often should I check my Santa Fe's tires?Check the air pressure once a month and before long drives, and do the coin test on the tread every few months. A good time for a full inspection is each fall, before the roads start breaking up. Do I have to replace all four tires at once?Not always, but it depends on your vehicle and how worn the other tires are. If your Santa Fe has all-wheel drive, keeping all four tires close in size and wear matters more, so replacing a full set is often the safer choice. On a front-wheel-drive model, a technician can tell you whether two new tires will do and which axle they should go on. Can a pothole damage a tire without me noticing?Yes. The cords inside a tire can break on impact, and a bulge may not show up until days later. If you hit one hard, look over the tire and wheel at your next stop, and pay attention to any new vibration or pulling. Is it safe to keep driving on a tire with a sidewall bulge?No. A bulge means the tire's internal structure is damaged, and it can fail suddenly, especially at highway speed or on another pothole. Switch to the spare and get the tire replaced as soon as you can. Should I get winter tires for my Santa Fe on Long Island?Plenty of local drivers do fine with good all-season tires that have healthy tread. If you're out early on untreated roads or drive a lot in snow and ice, winter tires give you noticeably more grip in the cold. Ask a technician which makes more sense for how and where you drive. |
