3 Reasons Not to Mix Car Tire Sizes for Driving Safety
JAKARTA, JANUARY 2026, It is not recommended to mix tires with different sizes, brands, tread patterns, and specifications on one vehicle as it can jeopardize safety and reduce performance. Ideally, all tires should have the same specifications on each wheel. Exceptions only apply to high-performance vehicles that are indeed designed to use different tire sizes. In general, always follow the tire specifications according to the manufacturer's recommendations.
Here are examples of mixed tires:
- Tires for different seasons (e.g., summer, rainy season)
- Run-flat tires with non-run-flat variants
- Tires with different tread patterns or sizes
- Tires from different manufacturers
Reasons Not to Mix Tires
- Uneven Tread Wear
Regular tire rotation and wheel alignment will provide uniform wear on all tires. Mixing tires will cause uneven weight distribution on all four wheels, and some tires will wear out faster than others.
- Poor Handling
Mixed tires can make driving difficult. The tires on your vehicle are designed with traction and handling properties. Mixing tires with different sizes, designs, and tread patterns can lead to handling and braking issues for the vehicle. Poor handling creates unstable driving conditions and increases the risk of accidents on the road.
- Limited Performance
Incompatible tires will not work together effectively for smooth and safe driving. This can prevent the vehicle from achieving optimal driving performance, limiting acceleration rates, maximum speed, and load capacity.
Tire Maintenance
Your tires can last between 5 to 10 years with proper maintenance. Mixed tires will force you to replace them sooner than expected. Identical tires will provide traction, grip, and overall safety. Tires play a crucial role in the comfort and handling capability of every vehicle. You should know how to choose the right tires for your vehicle to maintain comfort and safety.
Signs You Need to Replace Tires
Over time, tires will wear out and lose their effectiveness, posing risks to drivers and passengers. You should recognize the signs that indicate it is time to replace tires and understand how to choose replacement tires.
Tires should be replaced if the tread depth is less than 2/32 inches or if the wear indicators are flush with the tread. Also, check for cracks, bulges, tears, holes, or nails that are difficult to repair. Uneven wear, vibrations while driving, the car pulling to one side, and tire age over six years are signs that tires need to be replaced immediately.
