Should I replace one or both rear tires when a car's rear tire blows out?

[McGia]

When a car's rear tire blows out, both rear tires should be replaced. There are two main reasons for this: 1. Smoothness: Replacing both tires together ensures identical tread patterns on both sides, which better maintains driving smoothness. Additionally, when replacing both tires, it's necessary to perform dynamic balance correction to ensure even force distribution among all four tires. 2. Safety: Replacing both tires simultaneously helps maintain equal weight distribution for the vehicle body. Moreover, during braking and cornering, identical tread patterns on both sides not only enhance driving safety but also contribute to better fuel efficiency.
