Steering Wheel Shakes at Highway Speed but Feels Fine in Town? Start With Tires and Wheel Balance

If the steering wheel is smooth at city speeds but shakes between roughly highway speeds, tire and wheel balance are common first checks. Inspect for missing wheel weights, uneven tread, bulges, bent wheels, packed mud or snow, and recent tire-service history. A balance issue often changes with vehicle speed rather than engine rpm, but vibration can also come from tire defects, wheel runout, or worn steering and suspension parts. If the vehicle suddenly develops severe vibration after a pothole hit or a tire shows a bulge or separated tread, reduce speed and have it inspected before normal highway driving.
