Can you buy a single tire? Yes, you can buy a single tire, but it’s generally not recommended. Replacing only one tire can lead to uneven traction, affecting vehicle performance, handling, and safety. It’s best to replace tires in pairs or all four for optimal balance and performance.
Tires are an important component of the vehicle’s performance, safety, and comfort. When one tire wears out or gets damaged, it might seem tempting to replace only that one tire, especially if you’re trying to save some money. But is this a good idea?
In this guide, we’ll explain the implications of buying a single tire, the risks involved, and whether it’s worth considering. Let’s explore all the aspects you need to know about replacing just one tire instead of all four.

The Importance of Matching Tires
Tires are the only part of the vehicle that directly connects it to the road. As such, they play an essential role in the vehicle’s handling, traction, and overall performance. Tires that are uniform in size, tread depth, and wear ensure that the vehicle handles in a balanced and stable manner. When tires become mismatched, your vehicle’s performance can be compromised, leading to potential safety issues.
Replacing just one tire might seem like an easy and cost-effective solution, but it can cause more harm than good in the long run. Below, we’ll break down why tire uniformity matters and what happens when you choose to replace only one tire.
Importance of Tire Matching
When you drive, your vehicle relies on all four tires to function in unison. Each tire should have the same size, tread pattern, and wear level to ensure optimal performance and safety. The wear and tear on a tire affects how it grips the road, how much noise it produces, and how efficiently your car performs.
Impact of Tread Depth and Performance
Tires wear down over time, and the depth of the tread directly impacts how your car handles the road. New tires have deeper tread, providing more traction and stability, particularly in adverse weather conditions. However, as the tread wears down, tires lose their ability to grip the road effectively, especially during braking, turning, and accelerating.
If you replace only one tire while the other three are significantly worn, you could experience uneven handling. The new tire will have a deeper tread, while the older tires will have reduced traction. This difference in traction can lead to issues with braking, handling, and cornering, especially in wet conditions.
Risks for All-Wheel Drive (AWD) and Four-Wheel Drive (4WD) Vehicles
If the car is AWD or 4WD, the consequences of mismatched tires are even more significant. These vehicles rely on all four tires to rotate at the same speed to ensure proper functioning of the drivetrain and other related components. When you replace just one tire, you risk uneven rotational speeds between the tires, which can strain the differential, transfer case, and other drivetrain components.
In such cases, replacing a single tire may result in severe damage to expensive components like the transfer case or differential, leading to costly repairs.
When Can You Replace Just One Tire?
Although it’s generally advisable to replace all four tires, there are some exceptions where replacing just one tire may be acceptable:
Minimal Tread Difference
In some situations, if the tread difference between the new tire and the old ones is minimal, replacing just one tire may be acceptable. Most tire experts suggest that the difference in tread depth should not exceed 2/32” to 4/32”. If the new tire is within this range of the remaining tires, it may be fine to replace only one. However, this is only a temporary fix, and you should aim to replace the remaining tires soon to ensure uniformity.
Same Brand and Model
For the best results, the replacement tire should be the same brand, model, and size as the other tires. Tires from different manufacturers can have slight variations in their construction, which may affect performance and handling. Even if you buy the same tire, it’s important that the new tire matches the wear and age of the others.
Proper Tire Placement
Even if replacing just one tire is acceptable, it’s important to place the new tire in the correct position. For front-wheel-drive vehicles, the new tire should ideally be placed on the rear axle to ensure stability and reduce the risk of hydroplaning. For rear-wheel-drive vehicles, the new tire should go on the rear axle as well to maintain balanced handling.
Risks of Replacing Just One Tire
Replacing a single tire can introduce several risks, particularly in terms of vehicle performance, handling, and safety.
Uneven Traction and Handling
Mismatched tires can cause uneven traction between the tires, especially if one tire is new and the others are worn. This imbalance can affect braking, cornering, and acceleration, making the vehicle harder to control, particularly in slippery conditions.
Increased Wear on the New Tire
The new tire may wear out more quickly if it’s constantly working harder than the older tires. Because it has deeper tread, it will try to compensate for the worn tires, which leads to premature wear and reduced lifespan for the new tire.
Potential Drivetrain Damage
For AWD and 4WD vehicles, mismatched tires can cause strain on the drivetrain components, such as the transfer case, differential, and axles. This additional strain can lead to premature wear and costly repairs, especially if the mismatch causes excessive wear on the drivetrain parts.
Best Practices for Tire Replacement
To ensure that your vehicle remains safe and efficient, here are the best practices for tire replacement:
- Replace Tires in Pairs: If you’re unable to replace all four tires, try to replace them in pairs. This means replacing both tires on the same axle (front or rear). Doing so ensures that the tires wear more evenly and reduces the chances of traction imbalance.
- Rotate Your Tires Regularly: Regular tire rotation ensures that all four tires wear evenly. It’s generally recommended to rotate your tires every 6,000 to 8,000 miles (or as specified in your vehicle’s manual) to ensure balanced wear and to extend their lifespan.
- Check Your Tire Alignment: Misalignment of the tires can lead to uneven wear. Make sure the vehicle’s alignment is checked regularly to ensure that your tires are wearing evenly and that the vehicle is driving straight.
- Consider Buying Tires in Sets: Whenever possible, buy tires in sets of four. This will help ensure that your vehicle performs at its best and prevents uneven wear and handling issues.
- Consult a Professional Mechanic: If you’re unsure about whether to replace just one tire or the entire set, it’s always best to consult a professional mechanic or tire specialist. They can assess your tires’ condition and recommend the best course of action.
Frequently Asked Questions
Here are some FAQs about buying a single tire –
1. Can I replace just one tire on my car?
Yes, you can replace just one tire, but it’s not ideal. Mismatched tires can lead to uneven traction, affecting your vehicle’s handling and performance. It’s always best to replace tires in pairs or all four to maintain uniformity.
2. Can I replace one tire if the tread is slightly worn?
If the tread difference between the new tire and the worn ones is minimal (less than 2/32” to 4/32”), it might be acceptable to replace only one tire. However, this should be a temporary fix, and you should aim to replace the other tires soon.
3. How do I know if I need to replace my tires?
You can check the tread depth using the penny test: insert a penny into the tread with Lincoln’s head upside down. If you can see all of Lincoln’s head, it’s time to replace the tire.
4. What happens if I replace just one tire on an AWD vehicle?
Replacing just one tire on an AWD vehicle can strain the drivetrain and lead to costly repairs. It’s always better to replace tires in pairs or all four for AWD and 4WD vehicles.
5. Can I replace just one tire if it’s the same brand and size?
While it’s better to replace all tires at once, replacing one tire with the same brand, model, and size may be acceptable if the tread wear is not too different. However, you should still monitor your tire’s performance and aim to replace the others soon.
Conclusion
Replacing just one tire might seem like an easy solution, but it can compromise your vehicle’s safety, handling, and performance. Always prioritize uniformity across all four tires to ensure the vehicle performs at its best.
