Do you have to replace all four tires on an AWD RAV4?

The short answer is no, you do not necessarily have to replace all four tires on an all-wheel-drive (AWD) Toyota RAV4. However, there are some important considerations to keep in mind when replacing tires on an AWD vehicle.

Understanding AWD Tire Requirements

AWD vehicles, like the Toyota RAV4, are designed to distribute power to all four wheels to improve traction and handling in various driving conditions. To maintain the proper operation of the AWD system, it's crucial that the tires on an AWD vehicle have similar characteristics, such as size, tread depth, and wear. Replacing just one or two tires can disrupt the balance of the AWD system and potentially cause issues.

Replacing Tires on an AWD RAV4

• Replace all four tires: The best practice is to replace all four tires on an AWD RAV4 at the same time. This ensures that the tires have the same characteristics and the AWD system can function as intended.


• Replace in pairs: If you can't replace all four tires at once, you should replace them in pairs (front or rear) to maintain the balance of the AWD system. Mixing tires with different characteristics can cause the AWD system to malfunction.


• Match tire size and type: When replacing tires, make sure to use the same size, load rating, and speed rating as the original tires. Using mismatched tires can lead to issues with the AWD system and potentially cause damage.

By following these guidelines, you can ensure that your AWD Toyota RAV4 continues to perform as designed and avoid any potential problems with the AWD system.

Do I have to replace all four tires if I have AWD?

Yes, you generally have to replace all four tires on an AWD vehicle because mismatched tread depths can damage the drivetrain components like the differential and transfer case. If one tire is damaged, it's best to replace all four, unless the others are nearly new and the new tire's tread depth is within about 3/32 of an inch of the others. 
Why mismatched tires are a problem for AWD

• Drivetrain stress: AWD systems are designed to have all four wheels rotating at the same speed. A new tire with a significantly different tread depth will travel a different distance with each rotation compared to the worn tires. 
• Drivetrain damage: This constant difference in rotational speed creates uneven stress on the center differential and transfer case, which can cause them to overheat, wear out prematurely, or even fail. 
• Safety concerns: Inconsistent tire wear can also lead to unpredictable handling and can negatively affect the anti-lock braking and traction control systems. 

What to do if you need to replace one tire

• Check the tread depth: If the three existing tires are relatively new, you may be able to replace just one. 
• Match the new tire: The new tire's tread depth must be within about 3/32 of an inch of the others to avoid damaging the drivetrain. 
• Consult your manual: Always check your vehicle's owner's manual, as it will specify the acceptable tread depth difference. 
• Consider other options: If the three existing tires are too worn, consider finding a used tire with a similar tread depth to the ones on your car to avoid the cost of four new tires, says a YouTube video. 

How long do tires last on an AWD?

about 6 years
Tires typically last between 50,000-70,000 miles or about 6 years, depending on driving habits, maintenance, and environmental factors. Regardless of mileage, most manufacturers recommend replacement after 6-10 years due to natural rubber degradation.

Can I replace just one tire on a 4WD Toyota?

No, it is not recommended to replace just one tire on a 4WD Toyota because the difference in tread depth between a new and old tire can cause damage to the drivetrain, affect traction control, and lead to unpredictable handling. It is best to replace tires in pairs (preferably on the same axle) or all four at once to ensure even wear and proper system function. 
Risks of replacing only one tire

• Drivetrain damage: The difference in diameter between a new and worn tire can cause the AWD system to constantly work to compensate, putting excessive strain on the drivetrain components and potentially causing them to fail prematurely. 
• Traction control issues: A single new tire with more tread depth can send false signals to the car's computer, confusing the traction control and ABS systems. 
• Unpredictable handling: A mismatch in tread depth and grip can negatively impact the vehicle's handling, acceleration, and braking, which could lead to a dangerous situation. 

Recommended solutions

• Replace in pairs: The safest option if you can't replace all four is to replace at least two tires and put the new ones on the same axle (either both front or both rear). 
• Replace all four: This is the ideal solution, especially if your current tires have significant wear, to ensure all four tires have the same tread depth and size. 
• Match tread depth: If you must replace only one, consider finding a used tire of the same brand, model, and similar tread depth to minimize the difference with the other tires, though this is not ideal. 
• Consult a professional: Always consult with a tire professional or your Toyota dealer to get advice specific to your vehicle and current tire situation. 

Do you have to replace all four tires on a RAV4?

AWD System Damage: The difference in diameter of the tires can cause an AWD system to catch up on the dry pavement. This can sometimes damage the system. That is why almost every all-wheel-drive vehicle manufacturer recommends changing all tires simultaneously.
