DO I NEED TO REPLACE ALL FOUR TIRES?
BRYNA CHRISTENSEN • July 24, 2025
WHEN TO REPLACE ONE, TWO, OR ALL FOUR TIRES
Tires are one of the most important safety components on your vehicle, affecting traction, handling, and braking. But when it’s time for new tires, do you really need to replace all four at once? At Eureka Brake & Automotive,
we want to help you make the best decision for your vehicle, safety, and budget.
Here’s what you need to know.
WHEN YOU CAN REPLACE A SINGLE TIRE
Replacing just one tire is usually not recommended, but in some cases, it may be acceptable.
- If the other three tires have minimal wear (less than 2/32-inch difference in tread depth).
- If the replacement tire is the exact same brand, model, and size as the others.
- If your vehicle has two-wheel drive and the tires are not too worn.
However, even if replacing just one tire is an option, it can still cause slight imbalances in handling and traction, especially on wet or slippery roads.
WHEN TO REPLACE TWO TIRES
If only two of your tires are worn out, replacing them in pairs may be a good solution.
- Always install the newer tires on the rear axle for better stability and reduced risk of hydroplaning.
- The remaining two tires should still have enough tread depth to provide balanced handling.
- This is a more common option for front-wheel drive vehicles when only the front tires are worn.
Mismatched tread depth between the front and rear tires can affect traction, especially in bad weather.
WHEN YOU SHOULD REPLACE ALL FOUR TIRES
Some vehicles require all four tires to be replaced at the same time to maintain safe and proper performance.
- All-wheel drive (AWD) and four-wheel drive (4WD) vehicles require all four tires to have equal tread depth to prevent drivetrain damage.
- If the remaining tires are significantly worn (more than 4/32-inch tread depth difference).
- If switching to a different tire brand, model, or size for improved performance or safety.
AWD systems rely on even traction across all four wheels, so uneven tread depth can put extra strain on the drivetrain, leading to costly repairs.
