Avoiding potholes helps protect your GMC’s tires, wheels, alignment, suspension, steering, and underbody from sudden impact damage. Although GMC trucks and SUVs are engineered for confident capability, a deep pothole can still bend metal, damage rubber, and knock carefully calibrated components out of position. David Scott Lee Buick GMC near Milton, FL, can inspect your vehicle after a hard impact and address damage before it leads to additional wear. Schedule GMC service if your vehicle drives, sounds, or feels different after hitting a pothole.
A pothole may look like a minor road imperfection, but the impact can be surprisingly violent. When a tire drops into a deep hole, the wheel must move downward and then absorb the force of striking the opposite edge. The sharper the edge and the faster the vehicle is traveling, the greater the potential for damage.
GMC trucks and SUVs may carry substantial vehicle weight, passengers, cargo, or trailers. That weight affects how the tires, wheels, and suspension respond to an abrupt impact. Larger tires and added ground clearance can help in certain situations, but they do not make a vehicle immune to pothole damage.
Your tires create the first layer of protection between your GMC and the road. A properly inflated tire can absorb some impact energy, but a deep pothole may compress the tire against the wheel.
Visible damage is not the only concern. The force of a pothole strike can weaken the tire’s internal structure even when the tread appears normal.
Watch for:
A sidewall bubble may indicate that internal cords have been damaged. This condition can increase the risk of tire failure and should be inspected promptly.
A hard impact can bend an aluminum or steel wheel, damage its finish, or create a crack. A bent wheel may no longer form a secure seal with the tire, leading to a slow air leak. It can also produce vibration that becomes more noticeable as speed increases.
Your GMC’s wheel alignment determines how its tires meet the road. A strong pothole impact can alter suspension angles, causing the vehicle to pull away from a straight path or wear its tires unevenly.
Possible alignment symptoms include:
Ignoring an alignment problem can shorten tire life and make your GMC less predictable to drive. The damage may become especially expensive when multiple tires begin wearing along the inner or outer edges.
Alignment condition also matters when towing. GMC trailering technology, including available ProGrade Trailering System features, can support drivers during hitching and travel, but technology cannot compensate for damaged tires, bent wheels, or incorrect alignment. A mechanically sound vehicle provides the foundation for controlled towing.
The suspension allows each wheel to move while helping the body remain controlled. Pothole impacts place sudden stress on shocks, struts, bushings, ball joints, tie rods, control arms, and wheel bearings.
Pothole-related suspension damage may cause:
A shock absorber or strut does not need to break completely to create a problem. A damaged seal can allow fluid to leak, reducing the component’s ability to control wheel movement. Bent control arms or damaged steering parts can also affect alignment and handling.
GMC trucks and SUVs offer different amounts of ground clearance. Crossovers and models with lower front fascias may be more likely to scrape when entering or exiting a deep pothole. However, even a higher-riding GMC can sustain underbody damage when a crater is especially deep or has a sharp edge.
Areas that may be affected include:
Fresh fluid beneath the vehicle, scraping sounds, exhaust noise, or a hanging panel should not be ignored. An oil or transmission-fluid leak can become a serious mechanical concern if the vehicle continues operating with an inadequate fluid level.
Select GMC vehicles offer advanced suspension systems that respond to changing road conditions. Depending on the model and equipment, these systems may adjust damping to improve body control, comfort, or tire contact.
Continuous Damping Control evaluates vehicle movement and adjusts suspension damping as conditions change. The system can help the vehicle respond to uneven pavement, but its job is to manage ordinary road inputs, not eliminate the force of a severe pothole strike.
Repeated impacts can still accelerate wear on:
Tires and wheels
Available adaptive suspension technology found on select Denali models may help create a more composed ride, but avoiding a pothole remains far safer than asking the suspension to absorb it.
Traction control helps limit wheel slip, while available drive modes adjust certain vehicle responses for specific conditions. Off-Road or Terrain modes may help on appropriate loose or uneven surfaces when used as directed, but they do not protect the wheels and suspension from pothole damage.
Drive modes should match the conditions described in the owner’s manual. They are not a reason to maintain speed on broken pavement. When traveling on a paved road filled with potholes, slowing down and carefully steering around hazards remains the smarter approach.
Drivers cannot control road conditions, but a few habits can reduce the chance of an expensive impact.
Underinflated tires provide less protection between the wheel and the edge of a pothole. Overinflated tires may offer less cushioning and transmit more impact force to the wheel and suspension.
For proper tire care:
Following another vehicle too closely can block your view of upcoming road damage. A larger following distance provides more time to spot a pothole, reduce speed, and choose a safe path around it.
Extra space also reduces the risk of a sudden reaction that could send your GMC into another lane, toward a cyclist, or into oncoming traffic.
When a pothole cannot be avoided safely, reduce your speed before reaching it. Release the brake immediately before impact while maintaining firm control of the steering wheel. Heavy braking during impact shifts weight toward the front and limits the suspension’s ability to respond.
Remember to:
Standing water can hide a pothole’s depth and shape. Treat water-covered road damage cautiously, especially when you cannot see the pavement beneath it. After heavy rain, allow additional room ahead and reduce speed on unfamiliar roads.
Not every pothole strike causes damage, but unusual symptoms deserve attention. Pull over in a safe location and inspect the tires if the impact was severe.
Schedule a professional inspection if you notice:
A service technician can inspect the tires, wheels, alignment, steering, suspension, and underbody. Finding a developing problem early may prevent premature tire wear or damage to connected components.
A pothole may last only a second, but the damage it causes can affect every drive that follows. David Scott Lee Buick GMC near Milton, FL, can help determine whether a hard impact damaged your GMC’s tires, wheels, alignment, suspension, steering, or undercarriage.
Schedule a service appointment for a pothole damage inspection, tire evaluation, wheel alignment, or suspension diagnosis. Our team can explain the findings and recommend the appropriate repairs to help your GMC return to the road with confident handling.
