Is Wheel Alignment Necessary After Changing Tires?
2 Answers
Wheel alignment is not necessary after changing tires for the following reasons: 1. Replacing the rims and tires only affects the overall dynamic balance of the wheels and has no impact on the suspension. 2. Changing rims and tires merely alters the properties of the wheels, requiring only dynamic balancing, whereas wheel alignment pertains to the suspension's properties—these are two different matters. 3. Whether changing tires or rims, as long as the size remains consistent, wheel alignment is not required. Wheel alignment is necessary under the following circumstances: 1. After collision repairs. 2. After replacing the steering system or its components. 3. After replacing or adjusting the suspension system. 4. Uneven wear on one side of the front or rear tires. 5. The steering wheel feels excessively heavy, floats, or shakes while driving. 6. The car pulls to the left or right when driving straight.
A few days ago, I just had all four tires replaced, and the shop asked if I wanted a wheel alignment. I wasn’t in a hurry to do it at the time, but after driving for a week, I noticed the steering pulling slightly to the left and increased tire noise. I went for a check-up right away and found that the rear wheels were misaligned, causing uneven wear on one side. Actually, tire replacement itself doesn’t necessarily require an alignment unless the suspension or wheel hubs were disturbed during installation—for example, if the bolts were loosened when removing the wheels, potentially altering the angles. Alignment ensures the wheels are parallel for smooth driving, better fuel efficiency, and prevents premature tire wear. I learned my lesson: if everything feels normal after new tires—like no pulling or unusual noises—you might skip it. But for older cars or if you notice bumps, it’s safer to get it checked to avoid extra costs later.
