Whenever one of your tires gets damaged, it can be confusing to know whether you should replace just one tire or all four. You’re not alone; many drivers aren’t fully familiar with how modern tires work, even after years on the road. Because of this, understanding when and how to replace tires isn’t always straightforward.
Today’s tires no longer function like they did years ago. You can’t simply replace one tire or swap in a pair and call it done. Modern vehicles require tires that match in model, type, and even tread wear to ensure proper performance and safety.
Before answering whether you should replace one tire or all four, let’s cover a few key basics, and then schedule service at Morristown Chevrolet if you’re near Knoxville.
Key Points to Know
-
Modern vehicles require tires that match in size, model, and tread depth
-
Mismatched tires can affect braking, acceleration, and vehicle stability
-
All-wheel-drive vehicles are especially sensitive to tire differences
-
In some cases, replacing just one tire is possible—if conditions are right
Why All Tires Should Be Changed
The main reason for replacing all four tires, even if only one is damaged, is to ensure proper vehicle performance. New tires typically have a tread depth between 10/32 and 12/32 of an inch. Over time, tread wears down, reducing traction and changing how the tire performs.
On all-wheel-drive vehicles, replacing only one tire can cause issues because the new tire has a larger diameter than the worn ones. This difference can impact braking, acceleration, and overall balance, potentially leading to drivetrain stress.
For front-wheel-drive or rear-wheel-drive vehicles, replacing just one tire can still cause problems. Significant tread differences may send incorrect signals to systems like antilock brakes and traction control, especially if the remaining tires have lost more than half their tread.
When You Can Change Just One Tire
There are situations where replacing only one tire is acceptable. This is typically when the remaining tires are still in good condition and have minimal wear.
If the other tires have not lost more than 4/32 of their tread depth, replacing just the damaged tire may be an option. In this case, all four tires will still behave similarly, allowing you to avoid unnecessary replacement costs.
Things to Consider When Replacing Only One Tire
While replacing all four tires is always the safest option, keep these points in mind if you’re replacing just one:
Choose the Same Tire
Always select a tire with the same brand, model, size, and tread pattern. Mismatched tires can wear unevenly and affect handling.
Consider Tire Shaving
In some cases, a new tire can be shaved to match the tread depth of the others, helping maintain balance and performance.
Mount It on the Rear
Experts recommend installing the new tire on the rear axle. This helps reduce the risk of hydroplaning and improves stability during turns, especially in wet conditions.
Conclusion
Whether you can replace just one tire depends entirely on the condition of the remaining tires. If their tread wear is minimal, a single replacement may be sufficient. If not, replacing all four tires is the safer choice.
