Do I need a wheel alignment after replacing all tires?

Tire replacement does not necessitate a wheel alignment. Below are relevant details about wheel alignment: 1. Purpose: The function of wheel alignment is to maintain stable straight-line driving and easy steering of the vehicle, while reducing wear on tires and steering components during operation. 2. Scenarios requiring wheel alignment: The vehicle's driving performance is affected (the most direct experience for the driver is deviation in straight-line driving or failure of the steering wheel to return automatically after turning); damage to the chassis and suspension caused by an accident; abnormal tire wear (but it's also necessary to consider whether abnormal wear is due to incorrect tire pressure—generally, overinflation accelerates wear on the center of the tread, while underinflation accelerates wear on both sides of the tread; if one side shows uneven wear, it might indicate a deviation in the camber angle.); components of the axle or suspension have been removed.

After changing tires, it's not always necessary to do a wheel alignment. In my years of driving, I've found that unless the car was previously pulling to one side or the tires were wearing unevenly, there's no need to specifically get an alignment. It can extend the life of new tires, improve handling, and enhance fuel efficiency. For example, I once changed tires on my old car without an alignment, and within a few months, one side wore out faster, wasting the money spent on new tires. If the car drives smoothly and there are no strange noises after installing new tires, you might skip this step. However, be aware that if the car has recently hit a curb or frequently drives on rough roads, the alignment parameters might have changed. It's best to ask the technician during the tire change to check it for safety, to avoid long-term issues leading to potential hazards.

I don't consider wheel alignment mandatory after tire replacement, but from a technical standpoint, it's crucial for new tire performance. Improper alignment accelerates tire wear, disrupts handling balance, and may even cause steering wheel vibration. If the vehicle already exhibits uneven tire wear or unstable steering, these issues will become more pronounced with new tires. During normal driving, alignment parameters gradually shift due to road impacts, so even without noticeable problems, I recommend checking every tire change or 10,000-20,000 km. It's preventive maintenance with high ROI. Take my personal experience: skipping alignment cost me a set of prematurely worn tires within a year - a classic case of penny-wise, pound-foolish.

Getting a wheel alignment when replacing new tires is not mandatory. Unless your car shows symptoms like pulling to one side, uneven tire wear, or unstable driving, there's no need to fuss if the new tires fit fine. Alignment helps tires bear force evenly and enhances driving safety, but it costs money and time. I think of it like a health checkup—only necessary when there are minor issues; usually, just pay attention to the handling feel. If you do decide to get one, choose a reliable repair shop—a single alignment can last several years, saving you future hassles.
