How to Prevent / Check for Costly Damage Caused by Potholes

AAA recommends the following measures to help protect vehicles from, and check for, damage caused by potholes:

Inspect Tires — Make sure tires are properly inflated and have enough tread. An under-inflated or badly worn tire is more likely to suffer damage, or allow the wheel or suspension to be damaged, when hitting a pothole. When checking tire pressures, ensure they are inflated to the manufacturer’s recommended levels, which can be found in the owner’s manual or on a sticker on the driver’s doorjamb. Don’t use the pressure levels stamped on the sidewall of the tire.

To check the tread depth of tires, insert a quarter into the tread groove with Washington’s head upside down. The tread should cover part of Washington’s head. If it doesn’t, then it’s time for new tires.

Inspect Suspension — Make certain struts, shock absorbers and other suspension parts are in good condition. Changes in vehicle handling, excessive vibration or uneven tire wear can indicate damaged or worn components. Have the suspension inspected by a certified technician if you suspect problems.

Slow Down — If you can’t avoid a pothole, reduce your speed safely and check the rearview mirror before braking abruptly. Hitting a pothole at higher speeds greatly increases the chance of damage to tires, wheels and suspension components.

Beware of Puddles — A puddle of water can disguise a deep pothole. Use care when driving through puddles and treat them as though they may be hiding potholes.

Check Alignment — Hitting a pothole can knock the wheels out of alignment and affect the steering. If a vehicle pulls to the left of right, have the wheel alignment checked by a qualified technician.

Recognize Noises/Vibrations — A hard pothole impact can dislodge wheel weights, damage a tire or wheel, and bend or even break suspension components. If you begin noticing any new or unusual noises or vibrations after hitting a pothole, the vehicle needs to go into the shop immediately for an inspection by a qualified technician.
