Here's why this is the case:
1. Suspension Settings: The suspension system, which includes components like the control arms, tie rods, and strut assemblies, is responsible for maintaining the alignment of the wheels. During a wheel alignment, these components are adjusted to ensure that the wheels are in proper alignment with the chassis and steering components. When this alignment is done correctly for your regular tires, it should generally hold true for winter tires as well, given that the suspension settings remain the same.
2. Wheel Compatibility: If the winter tires you are using have the same size, aspect ratio, and wheel offset as your regular tires, they should fit onto the vehicle without significantly altering the wheel alignment settings. As long as the wheelbase, track width, and suspension geometry of the vehicle remain unchanged, the alignment settings should be suitable for both sets of tires.
3. Installation: When you switch to winter tires, it's important to follow the proper installation procedures and ensure that the wheels are mounted and torqued correctly. If done properly, this process shouldn't affect the wheel alignment.
However, it's always a good practice to have your vehicle's alignment checked regularly, especially if you notice any issues such as uneven tire wear or pulling to one side while driving. This can be done at a reputable tire shop or automotive service center to ensure that your vehicle's alignment is in optimal condition, regardless of whether you're using regular tires or winter tires.
