You don't need to replace a pair of tires after a blowout at 20,000 kilometers. Here is a brief introduction on whether to replace tires: 1. Wear degree: For normally used vehicles, owners should periodically check the tire tread patterns. If severely worn, replacement is necessary. 2. Number of repairs: Generally, if a tire has been repaired twice or more, it is also recommended to replace the tire. Because such tires pose a risk of blowout during high-speed driving. 3. Usage time: Another factor is the duration of use. Even if the tires are used less, after 5 or 6 years, attention should be paid to the degree of aging. For safety reasons, tires should be replaced if they have been in use for more than 5 years.

I've been driving for over a decade and have experienced several tire blowouts. When a tire blows out at 20,000 kilometers, whether you need to replace a pair of tires depends on the wear condition of the other tire. Generally, tire wear should be consistent to ensure vehicle handling and safety. If the tread on the other tire is still deep and the wear is similar, replacing just one is sufficient. However, if the other tire is severely worn with a tread depth difference exceeding 2 millimeters, it's strongly recommended to replace both. Otherwise, the imbalance can affect steering and braking, especially in rainy or snowy conditions, which is particularly dangerous. I encountered a similar issue before—I saved some money by replacing just one tire, but the car became unstable, and I had to redo the job by replacing the entire set. Regular maintenance checks on tire pressure and alignment can prevent many problems.

As a budget-conscious car owner, I think this depends on your budget and tire condition. 20,000 kilometers isn't considered high mileage. If the other tire is still relatively new after a blowout, there's no need to spend extra money replacing both. However, make sure to use the same brand and model to avoid differences in grip that could cause loss of vehicle control. I've been in a similar situation - replacing just one tire is cheaper, but uneven wear might accelerate aging of other tires, potentially leading to higher repair costs later. I recommend using a tread depth gauge to measure the difference between the two tires; if the difference is minimal, replace just one, otherwise replacing both is more cost-effective and safer. Don't forget to compare prices at different repair shops - sometimes you can find good deals.

From a tire technology perspective, there are risks in not replacing a pair after a blowout. Differences in wear between left and right tires can affect the vehicle's balance, potentially causing body tremors during steering or extended braking distances. A blowout at 20,000 kilometers suggests that tire may have aging or damage issues, so it's advisable to measure the tread depth of the other tire. If the difference exceeds 1/8 inch, replacing both is recommended, especially for drive wheel positions. Having dealt with such issues, I confirm that only installing tires of identical specifications ensures equal traction. Regular tire rotation can prevent uneven wear and extend overall lifespan.
