What Size Is 285 Tires?
When it comes to tires, understanding the size and dimensions is crucial for ensuring a proper fit on your vehicle. One common tire size that raises questions is 285. But what does this size mean, and how does it affect your vehicle’s performance? (See Also: Why Do They Put Nitrogen In Tires)
Breaking Down the 285 Tire Size
The 285 tire size is a measurement that indicates the tire’s width in millimeters. To break it down further, let’s look at the components of a tire size:
- Tire width: This is the first number in the size, which represents the tire’s width in millimeters. In this case, it’s 285mm.
- Aspect ratio: This is the second number, which represents the tire’s height as a percentage of its width.
- Rim diameter: This is the third number, which represents the diameter of the wheel in inches.
So, a 285 tire size would be written as 285/XXRXX, where XX is the aspect ratio and RXX is the rim diameter. For example, a common size might be 285/70R17.
What Does the 285 Width Mean?
The 285 width is considered a relatively wide tire, which can have both advantages and disadvantages. Here are some key points to consider:
- Improved traction: A wider tire provides a larger contact patch with the road, which can improve traction and handling, especially in dry conditions.
- Better stability: A wider tire can also improve stability, particularly at high speeds or when cornering.
- Increased rolling resistance: Wider tires can increase rolling resistance, which can negatively impact fuel efficiency and acceleration.
- Wider tires may require more clearance between the tire and surrounding components, such as fenders or suspension components.
It’s essential to consider these factors when deciding whether a 285 tire size is suitable for your vehicle.
Vehicle Compatibility
Not all vehicles can accommodate a 285 tire size. Here are some factors to consider when determining compatibility:
- Fender clearance: Ensure the tire has sufficient clearance from the fender to avoid rubbing or damage.
- Suspension clearance: Verify that the tire has adequate clearance from suspension components, such as control arms or steering components.
- Rim size: Ensure the rim size matches the tire size, and that the rim is designed for the tire’s load rating.
- Load rating: Verify that the tire’s load rating meets or exceeds the vehicle’s gross axle weight rating (GAWR).
It’s crucial to consult your vehicle’s owner’s manual or manufacturer’s specifications to determine the recommended tire size and ensure compatibility.

Popular Vehicles That Use 285 Tires
Several popular vehicles come equipped with 285 tires from the factory or can accommodate them as an upgrade. Here are a few examples:
- Jeep Wrangler Rubicon
- Ford F-150 SVT Raptor
- Chevrolet Silverado 1500 Z71
- Ram 1500 TRX
- Toyota 4Runner TRD Pro
These vehicles often have larger wheels and more aggressive tires to enhance their off-road capabilities or improve their overall performance.
Conclusion
In conclusion, the 285 tire size is a relatively wide tire that can provide improved traction and stability, but may also increase rolling resistance and require more clearance. It’s essential to consider vehicle compatibility, load rating, and rim size when deciding whether a 285 tire size is suitable for your vehicle. By understanding the components of a tire size and consulting your vehicle’s specifications, you can make an informed decision about the right tire size for your needs.

Frequently Asked Questions about 285 Tires
What is the diameter of a 285 tire?
A 285 tire has a diameter of approximately 33-34 inches, depending on the specific tire model and brand. This is a common size for larger vehicles, such as trucks and SUVs, and provides a good balance between ground clearance and handling. (See Also: Do Tractor Tires Have Tubes)
What is the width of a 285 tire?
A 285 tire is approximately 11.2-11.5 inches wide, which is wider than a standard tire. This increased width provides more traction and stability, especially on uneven or slippery surfaces.
Can I put 285 tires on my vehicle if it didn’t come with them?
It depends on your vehicle’s make and model, as well as its suspension and axle capabilities. You should consult your vehicle’s owner’s manual or speak with a mechanic or tire professional to determine if 285 tires are compatible with your vehicle. They can help you ensure that the larger tires won’t cause any clearance or rubbing issues.
Do 285 tires affect my vehicle’s fuel efficiency?
Yes, larger tires like 285s can affect your vehicle’s fuel efficiency. The increased rolling resistance and weight of the tires can decrease your vehicle’s gas mileage, especially in city driving or stop-and-go traffic. However, the impact on fuel efficiency will vary depending on your vehicle and driving habits.
Can I use 285 tires for off-road driving?
Absolutely! 285 tires are well-suited for off-road driving due to their increased ground clearance and traction. They can handle rough terrain, such as rocks, mud, and sand, and provide a more stable and confident ride. Just be sure to check the tire’s tread pattern and sidewall strength to ensure they’re designed for off-road use.
