What are the symptoms of excessive toe-in when driving at high speeds?

Excessive or insufficient toe-in in a vehicle can lead to increased tire wear, accelerated wear of the front suspension, and reduced comfort, among other issues. Below is an introduction to the related content: 1. Self-centering: The steering wheels should have a self-centering effect. 2. Front wheel toe-in: When installing the wheels, the distance between the front edges of the two wheels is less than the distance between the rear edges, and the difference between these two distances is the front wheel toe-in. 3. To ensure stable straight-line driving: The steering wheels should have a self-centering effect, meaning that when the steering wheels are subjected to an external force (such as hitting a stone) and deviate, they can immediately return to the straight-line driving position once the external force disappears. This self-centering effect is guaranteed by the positioning parameters of the steering wheels. Front wheel toe-in is one of these positioning parameters.
I've noticed that excessive toe-in makes the car particularly unstable at high speeds, with the steering prone to wandering around, as if a little elf is tugging at the steering wheel. Tire wear becomes significantly faster, usually with the inner edges wearing out first, due to the misaligned wheel angles increasing friction. At highway speeds, the vehicle may also experience shaking, with vibrations felt underfoot and the steering wheel wobbling along. Over time, fuel consumption increases as well, because the added resistance forces the engine to work harder. Back when I used to help with car repairs, I often heard customers complain about the car swaying during long trips, which is quite dangerous and calls for prompt wheel alignment checks.
As a young driver who frequently takes highways, I remember being really nervous about that toe-in issue. Once the speed exceeded 100 km/h, the car started swaying left and right, and I had to grip the steering wheel tightly to keep it straight. The tires made strange humming noises, with obvious grooves worn on the inner side. Later, I found out it was caused by an excessive toe-in angle. It also led to higher fuel consumption than usual, so I rushed to the repair shop to fix it and avoid more problems. That sense of insecurity during long-distance driving was truly unsettling.
Having driven for a lifetime, I believe the most noticeable symptom of excessive toe-in at high speeds is poor steering control. The car tends to drift to one side frequently, requiring constant correction, which increases the risk of rear-end collisions. Uneven tire wear leads to rapid deterioration, forcing you to spend money on replacements. Elderly drivers especially need to prioritize safety—I once overlooked this issue and nearly had an accident. You can identify the problem by checking the tires for sawtooth-shaped wear patterns on the inner edges.
