245 Vs 315 Tires
The main difference between 245 and 315 tires is their width. The width of the 245 tires is 245 mm, while the 315 tire is 315 mm wide. This difference in width corresponds to a difference in tread width of approximately 70 mm.
The 245 tire is much narrower than the 315 tires. This difference in size means that the 245 tires will provide a softer ride and less traction when cornering. The 315 tires will provide a firmer ride and more traction when cornering.
245 Vs 315 Table
This comparison table provides a convenient and concise overview of the differences between two tire sizes, allowing for easy identification of the key distinctions between them.
| 245 Tire Size | 315 Tire Size |
|---|---|
| More comfortable ride | Maximum traction on dry roads |
| Generally less expensive | Better handling performance |
| Better traction in snow, rain, and slush | Suitable for heavier loads |
| Better fuel economy | More attractive appearance |
| Recommended rim width range: 8 to 10 inches | Recommended rim width range: 8.5 to 10.5 inches |
| Smaller than 315 tire size by 70 millimeters | Larger than 245 tire size by 70 millimeters |
| Can replace 315 tire size (shared rim width range) | Can replace 245 tire size (shared rim width range) |
Rim Width Range
Rim width plays a crucial role in vehicle performance. Increasing rim width with the same tire size results in a marginally wider tire and a firmer sidewall. This enhances steering responsiveness but may compromise ride comfort due to decreased impact absorption.
Decreasing rim width while keeping tire size constant leads to a slightly narrower tire and a more flexible sidewall. This can result in softer handling but potentially offer a smoother ride experience.
Fuel Economy
Regarding fuel economy, the difference between 245 and 315 tires can be significant. Wider tires create more rolling resistance, resulting in a decrease in fuel economy.
While it might be tempting to go with the wider option for improved handling and aesthetics, it’s important to consider the trade-off of lower fuel efficiency. In summary, if your main concern is fuel efficiency, it might be preferable to opt for narrower tires.
Ride Comfort
When it comes to riding comfort, there is no doubt that narrower tires like the 245 size tend to provide a smoother experience. This is due to their higher sidewall ratio and extra cushioning, which help to absorb any bumps and imperfections in the road.
As such, opting for the 245-size tires would be ideal if you want a more comfortable ride. Plus, they can help to minimize the impact of road imperfections on your vehicle too. So, if you value smoothness and comfort over fuel economy, then going with these narrower tires could be an excellent choice.
Dry Traction
Regarding dry traction, 285 tires have a clear advantage over 245. Thanks to their larger contact patch, 285 tires offer increased grip on the road, allowing drivers to corner and brake with more confidence.
Ultimately, it’s important to weigh your driving needs and priorities when deciding between tire sizes – if you prioritize dry traction, the 285 tire is your best bet!
Handling Performance
Regarding handling performance, the wider 315 tires can offer a noticeable advantage. With their larger contact patch, they provide more grip and stability during cornering, allowing for greater control and confidence while taking turns.
Not only is there an improvement in stability and driving satisfaction, but these tires also allow for quicker acceleration out of the corner due to better traction on the road surface. To put it simply, these bigger tires can provide an extra boost when it comes to tackling challenging roads.
Load Capacity
Regarding load capacity, 315 tires have a clear advantage over 245 tires. With a larger contact patch, the vehicle’s weight is spread out over a greater surface area, allowing the tire to handle higher loads easily.
This makes them ideal for heavier vehicles such as SUVs and trucks, where the need for reliable support and stability is paramount. Thanks to their increased load capacity, 315 tires give you the confidence that your ride will be able to handle whatever life throws at it!
What Does 315 Mean On A Tire?
The number 315 on a tire represents its width in millimeters. In this case, a tire with a “315” designation has a width of 315 millimeters from one sidewall to the other. The full tire size would typically be written as 315/xxRyy, where xx denotes the aspect ratio (sidewall height as a percentage of tire width), and yy refers to the wheel diameter in inches.
How Much Wider Is A 315 Tire Than A 245?
To determine the width difference between 315 and 245 tires, you can subtract the smaller width from the larger width: 315 millimeters – 245 millimeters = 70 millimeters.
So, a 315 tire is 70 millimeters wider than a 245 tire. To convert this difference to inches, use the conversion factor: 1 inch = 25.4 millimeters.
70 millimeters / 25.4 millimeters/inch = 2.76 inches
Therefore, a 315 tire is approximately 2.76 inches wider than a 245 tire.
Can I Replace 245 Tires With 315?
Swapping out 245 tires for 315 is not possible, it’s important to bear a few things in mind. The width range of the wheels needs to fit the tire size, as 315 generally fit 9.5-11.5 inch wheels and 245 are designed for 7-8.5 inch rims. Evidently, there is no shared rim width range between the 245 and 315 tires. Consequently, we can conclude that they are not interchangeable.
