Why does the car feel floaty after changing tires?

[MartinAnn]

After changing tires, the car may feel floaty because the wheel balancing was not performed post-replacement, causing an imbalance in the tires at high speeds, which leads to a floating sensation. Here are some precautions to take when changing tires: 1. Replace two tires at the same time: It is rare for all four tires to reach the end of their lifespan simultaneously. When one tire is damaged or punctured and needs replacement, it is advisable to replace both tires on the same axle. This helps prevent skidding during emergency braking due to uneven friction between the left and right tires. 2. Rebalance the wheels: Each wheel must be rebalanced when changing tires. Due to manufacturing variations, mass distribution in wheels may not be perfectly uniform. At high speeds, this can cause dynamic imbalance, resulting in wheel wobbling and steering wheel vibrations. Wheel balancing effectively prevents such issues.
