Bob Howard Chevrolet's service department in Oklahoma City replaces, balances and aligns tires on Chevrolets for drivers across the metro, including Edmond, Moore, Norman and Yukon. Replace a tire when its tread reaches 2/32 of an inch, the point where the tread-wear bars sit flush with the tread, and plan ahead once it's down to 4/32 if you drive a lot in rain. Rotate every 7,500 miles, the interval GM recommends for 2011 and newer vehicles. Have the alignment checked whenever you install new tires or notice pulling, an off-center steering wheel, or uneven wear.
Most tires don't fail suddenly. They give warnings you can check in the driveway in a couple of minutes.
| What you notice | What it usually means | What to do |
|---|---|---|
| Cracks in the sidewall or between tread blocks | Rubber aging, often accelerated by heat and sun | Have it inspected; replace if cracks are deep |
| Bulge or bubble on the sidewall | Internal damage, often from a pothole or curb | Replace immediately; don't drive on it at speed |
| One edge worn faster than the other | Alignment is off | Alignment check, then assess the tire |
| Vibration that grows with speed | Out-of-balance wheel or a damaged tire | Balance and inspection |
| Tire pressure warning that keeps returning | A slow leak, a nail, or a failing valve stem | Inspection and repair or replacement |
Put a penny upside down into a main tread groove. If you can see the top of Lincoln's head, the tread is below 2/32 of an inch and the tire is due. Check several spots across each tire, because uneven wear can hide in one groove.
Every tire has small raised bars molded across the bottom of its grooves. When the surrounding tread wears down level with them, the tire has reached 2/32 of an inch.
Look for the DOT code on the sidewall. Its last four digits give the week and year the tire was built, so "2421" means the 24th week of 2021. Rubber ages even when tread looks fine. NHTSA notes that some vehicle manufacturers recommend replacing tires six years after production regardless of tread, and your owner's manual lists Chevrolet's guidance for your model.
Chevrolet's own guidance on reading tire wear is on Chevrolet's tire support page, and NHTSA recommends replacement at 2/32 of an inch.
These four services get confused constantly, and each fixes a different problem.
| Service | What it does | When you need it |
|---|---|---|
| Tire replacement | Swaps worn or damaged tires for new ones | Tread at 2/32 in., sidewall damage, or tires aged out |
| Wheel alignment | Adjusts the angles of the wheels so they point straight and sit square to the road | When any alignment symptom below appears, after a hard pothole hit or suspension work, and with new tires |
| Tire rotation | Moves tires between positions so they wear evenly | Every 7,500 miles on 2011 and newer GM vehicles |
| Wheel balancing | Adds small weights so each wheel spins without wobble | Vibration at highway speed, and whenever a tire is mounted |
An alignment problem rarely announces itself all at once. It shows up as a handful of small symptoms that get easier to ignore the longer you live with them.
On a straight, level road, the Chevy drifts left or right when you relax your grip. Pulling often worsens after a pothole.
The wheel sits tilted while you drive straight, or it doesn't return to center smoothly after a turn.
Inner or outer shoulders wear down faster than the middle. Left alone, this shortens tire life considerably.
Because misalignment eats tread, installing new tires on a truck or SUV that's out of alignment wastes part of the investment. An alignment check at the time of replacement protects the new set.
Central Oklahoma is hard on tires in ways that don't show up in a national average. Summer pavement temperatures bake the rubber and speed up sidewall aging, especially on vehicles parked outside. Fall and spring bring big day-to-night temperature swings, and tire pressure drops as air cools. That is why a tire pressure light often appears on the first cold morning of the season, even on healthy tires.
Road conditions add wear too. Freeze-thaw cycles open potholes on metro highways and county roads, and a single hard hit can bend a wheel, break a tire's internal belts, or knock the alignment out. Trucks and SUVs that spend time on gravel or rural roads around Norman, Yukon and the edges of the metro see more cuts and chips in the tread than vehicles kept on city streets.
The practical defense is simple. Check pressures monthly and whenever the seasons turn, using the pressure on the driver's door-jamb label, not the maximum printed on the tire. Rotate on schedule, and have any pothole-related pull checked promptly. The Chevy battery guide covers the other component Oklahoma's heat quietly shortens.
The tires that came on your Chevrolet were specified for that model's weight, handling and tire pressure monitoring system. Start by matching what the vehicle was built for, then choose a tread type for how you actually drive.
| What to match | Where to find it | Why it matters |
|---|---|---|
| Size | Driver's door-jamb label or the current sidewall | Keeps speedometer, stability control and clearances correct |
| Load index | Sidewall, after the size | Must meet or exceed the original, especially on trucks that haul |
| Speed rating | Sidewall letter after the load index | Matches the handling the vehicle was engineered around |
| GM TPC Spec number | Sidewall of original-equipment tires | Identifies tires built to GM's specification for that vehicle |
Best for commuters and family SUVs. A quieter ride and longer tread life on pavement.
Best for Silverado and Colorado owners who leave the pavement. Better grip and cut resistance on gravel and dirt.
Best for trucks that tow or haul heavy. Stiffer construction and higher load ranges, such as E, carry heavier loads.
On all-wheel-drive and four-wheel-drive Chevrolets, check your owner's manual for guidance on replacing tires in sets, since uneven tread depths across axles can strain the drivetrain. The Bob Howard tire finder shows the options for your specific vehicle.
Tires touch more of your vehicle's systems than they used to. A tire change on a modern Chevy may involve the tire pressure monitoring sensors and, on vehicles with driver-assistance features, systems that depend on the vehicle tracking straight. Chevrolet-trained technicians work on these vehicles every day, and a tire visit is also a convenient time to catch worn brakes or suspension parts. Read more about Chevrolet certified service and repair in OKC, or see how dealership service compares with independent shops. Tire service pairs well with a full inspection, and you can book both together through Bob Howard's Chevrolet service scheduling.
The technician measures tread depth on every tire, checks sidewalls for damage and aging, and reads the wear pattern, which often points to an alignment or inflation problem.
New tires are mounted, each wheel is balanced so it spins smoothly, and the tire pressure sensors are checked so the monitoring system reads correctly.
On an alignment machine, the wheel angles are measured against Chevrolet's specifications for your model and adjusted back into range.
Tires are set to the pressure on the door-jamb label, and the vehicle is checked for pull and steering-wheel position before it goes back to you.
Where can I get new tires for my Chevy in Oklahoma City?
Bob Howard Chevrolet's service department sells, mounts and balances tires for Chevrolet vehicles and serves drivers from Oklahoma City, Edmond, Moore, Norman and Yukon. You can look up tires for your vehicle with the online tire finder and schedule the installation online.
When should I replace my Chevy's tires?
Replace a tire when the tread reaches 2/32 of an inch, which is when the tread-wear bars are flush with the tread or you can see all of Lincoln's head in the penny test. Replace it sooner if you find sidewall bulges, deep cracks, or damage from a road hazard.
How often should I rotate my Chevy's tires?
Every 7,500 miles for 2011 and newer GM vehicles. Check your owner's manual for your specific model.
Do I need an alignment when I get new tires?
An alignment check is recommended with every new set. Misalignment wears tires unevenly, so correcting it before the new tires put on miles protects their tread life.
Why does my tire pressure light come on when it gets cold?
Air pressure drops as temperatures fall, so the first cold morning of fall often pushes a tire below the warning threshold. Add air to the pressure on the driver's door-jamb label. If the light returns, have the tire checked for a slow leak.
Can hitting a pothole throw off my alignment?
Yes. A hard pothole or curb impact can shift alignment angles, bend a wheel, or damage a tire internally. If the vehicle pulls or the steering wheel sits off-center afterward, have it checked.
Pick a time that fits your week, tell the service team what you've noticed, and they'll check tread, pressure and alignment while your Chevy is in. Current tire and service offers are on the service and parts specials page.
