Is a Wheel Alignment Necessary When Replacing All Four Tires on a Car?
2 Answers
For tire wear caused by normal driving, replacing all four tires does not require a wheel alignment, and in fact, performing one would not be particularly beneficial. However, it is common for a free wheel alignment to be offered when replacing all four tires at once. Therefore, you may choose to have a wheel alignment done, but only if it is offered for free. More detailed information is as follows: A wheel alignment is meaningful only when the vehicle exhibits the following phenomena: 1. Abnormal tire wear, such as uneven wear on one side; 2. The vehicle pulls to one side during normal driving; 3. The steering wheel is not centered when driving straight; 4. The vehicle's suspension system has been involved in a collision; 5. Multiple components of the suspension system have been replaced, such as the control arm or tie rods.
I've changed tires several times, and honestly, replacing all four tires doesn't necessarily require an immediate wheel alignment. Alignment mainly adjusts the angles of the suspension system, like tire deflection. If you're just installing new tires without touching the suspension components, the wheel angles usually remain unchanged. However, there's a key point: if the old tires showed uneven wear, such as excessive wear on one side, it indicates potential suspension issues. It's a good idea to check the alignment when changing tires. I once took the easy way out by driving off right after getting new tires, only to find uneven tire wear a few months later, forcing me to spend extra money on alignment—quite a hassle. Now, I've made it a habit to have the mechanic briefly check the angles during tire changes and only use the alignment machine if issues are found. This saves time and protects the new tires. Overall, replacing all four tires isn't a major procedure, but if you notice steering misalignment or vibration risks while driving, don't delay. Alignment can prevent uneven wear and enhance driving safety.
