245 vs 285 Tires
The main difference between 245 and 285 Tires tires is in the section width. The tire size 285 is about 40 millimeter wider than 245 tire size. The wider width of the tire can impact its performance and appearance when installed on the vehicle.
245 vs 285 Tires
| 285 Tire | 245 Tire |
|---|---|
| Lower Gas Mileage due to more rolling resistance and rotational mass | Higher Gas Mileage due to smaller contact patch and lower weight |
| More comfortable ride due to wider contact patch and taller sidewall | Less comfortable ride with smaller contact patch |
| More aggressive look but worse for aerodynamics | Better for aerodynamics but less aggressive aesthetics |
| Improved stability and traction, good for off-road | Enhanced handling and response, better for on-road |
| Potentially more road noise, less vibration | Quieter on smooth roads, more vibration from irregularities |
| Endures impacts but causes more component wear | Potential for longer tread life and even wear |
| Higher due to larger contact patch | Lower due to smaller contact patch |
| Better traction in mud, snow, off-road | Can cut through snow/ice more effectively |
Gas Mileage
With a slightly smaller contact patch and less rotational mass, 245 tires generally confer better fuel efficiency, an aspect crucial for daily commuters and long-distance travelers.
The larger 285 tires might detract from fuel efficiency owing to increased rolling resistance and rotational mass from the heavier weight.
Ride Comfort
The wider 285 tires generally offer a more comfortable ride than 245 tires due to their wider contact patch and taller sidewall.
However, the 245s tend to perform better on-road, while the 285s are better suited for off-road driving.
Aesthetics
The 245 tires contribute positively to vehicle aerodynamics, whereas 285 tires can offer a more aggressive and aesthetic appeal but may hinder aerodynamic efficiency.
Ultimately, tire choice comes down to finding the right balance of form and function based on intended vehicle use.
Handling & Stability
Due to the more minor contact patch, the 245 tires typically offer enhanced handling and quicker response on paved roads.
Conversely, the wider 285 tires might present improved stability and traction, particularly in off-road scenarios or on uneven surfaces because of the larger contact area.
Noise & Vibration
The 245 tires may provide a quieter ride on smooth surfaces but might transmit more vibrations from road irregularities.
The 285 tires, especially those with aggressive treads, might generate more road noise but could also dampen vibrations.
Durability & Wear
The 245 tires can potentially exhibit even wear and potentially longer tread life. While the 285 tires might endure more impacts, they also absorb more stress, introducing more wear to vehicle components due to their added weight.
Load Capacity
The load capacity increases with the 285’s wider tire width because it has a larger contact patch to distribute weight over a wider area. The 245 would have a decreased load capacity by comparison.
Adverse Conditions
The narrower 245 tires can sometimes navigate snow and ice more effectively by cutting through to the road surface compared to the 285 tires.
However, the wider 285 tires provide better traction in specific off-road or muddy conditions.
Difference Between 245 And 285 Tires?
The primary dissimilarities between 245 and 285 tires are in their section width, diameter, and speedometer readings. A 285 tire is 40 mm wider than a 245 tire, which gives it a more aggressive and muscular look.
How Much Wider Is A 285 Tire Than A 245?
The 285 tire is 40 millimeters wider than the 245 tire. With 1 inch equivalent to 25.4 millimeters, the width difference between these tires is about 1.57 inches.
Can I Use 285 Tires Instead Of 245?
Typically, using tires that differ in diameter by more than 3% compared to the original ones is not recommended. For instance, a 245/75R16 tire has an overall diameter of 30.47 inches, while a 285/75R16 tire has an overall diameter of 32.83 inches.
If you want to compare the size of two different tires, let’s say a 285/75R16 and a 245/75R16, you will notice that the difference between them is approximately 2.36 inches or 7.8%. It’s important to note that this exceeds the recommended 3% difference between tires.
Choosing a 285/75R16 tire instead of a 245/75R16 may cause rubbing or clearance issues. Following the manufacturer’s recommended tire size is recommended to avoid any potential problems.
What Size Is 285 Tire?
The tire size notation, such as “285,” typically refers to the tire’s section width in millimeters. The 285 tire refers to its width in millimeters, meaning it has a width of 11.2 inches.
This measurement represents the tire’s widest point, from sidewall to sidewall, when the tire is mounted on its specified rim width.
How Tall Is A 285 Tire?
Assuming a 16-inch wheel size, a tire with 285 tire size and 75 aspect ratio. The sidewall height of the 285 tire would be 285 x 0.75 = 213.75 millimeters.
Both sidewalls have a height of 157.5 mm, resulting in a total height difference of 427.5 mm or 16.831 in.
So, the 285 tire size height is 16.831 + 16 inches = 32.83 inches. Therefore, a 285 tire with a 70 aspect ratio mounted on a 16-inch wheel would be approximately 32.83 inches tall.
