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.

I was quite hesitant about whether to get a wheel alignment when I changed my tires. The mechanic explained that it mainly adjusts the angles of the wheels to ensure they aren't crooked or tilted, otherwise the tires would wear unevenly and affect grip. I looked it up and learned that if you're just replacing the tires without touching other components, alignment might not be necessary. But if after changing tires, the steering wheel shakes or the car pulls to one side, then alignment is a must. From my own experience, I think the risk is low for new cars or well-maintained vehicles, so you might skip it. However, just to be safe, I still regularly check the wheel alignment—it can extend tire life by tens of thousands of kilometers.

Generally, a wheel alignment is not necessary immediately after changing tires, unless suspension components were moved during installation or the wheel alignment was disturbed during the removal or installation process. From my experience, alignment can prevent wheel angle issues, such as the vehicle pulling to one side causing uneven tire wear or increased fuel consumption. In most cases, if the car drives smoothly after changing tires, there's no issue. However, if abnormal behavior occurs after driving on bumpy roads, checking the alignment is more cost-effective than replacing new tires. In terms of safety, proper wheel alignment enhances handling and provides more stability when driving at high speeds in rainy conditions.
