245/70R17 Vs 265/70R17: Comparing Gas Mileage for Different Tire Sizes

245/70R17 tires usually provide better gas mileage than 265/70R17 tires.

245/70R17 Vs 265/70R17 Gas Mileage

The debate around which tire size offers better gas mileage between 245/70R17 and 265/70R17 continues to rage on among drivers. It all boils down to the difference in their physical size, which consequently affects their performance and fuel efficiency. The 245/70R17 tires are slightly narrower and shorter than the 265/70R17 tires, providing them with a higher gear ratio for a smoother ride, albeit at the cost of fuel economy. The wider 265s offer increased traction and stability, allowing them to perform better on off-road terrain or slippery surfacesall with improved fuel efficiency compared to their narrower counterparts. Ultimately, the choice between the two will depend solely on the driver’s preferences. Whether you’re looking for a comfortable ride or some serious off-road capabilities, one of these two tire sizes should meet your needs.

Tire Size

The size of the tire for 245/70R17 and 265/70R17 are two different measurements. The size of the 245/70R17 tire is 24.5 inches in diameter, with a sidewall height of 70 percent of the width (7 inches), and a 17-inch wheel diameter. The 265/70R17 tire has a diameter of 26.5 inches, with a sidewall height of 70 percent of the width (7.7 inches), and a 17-inch wheel diameter.

Gas Mileage

When it comes to fuel efficiency, there is not much difference between 245/70R17 and 265/70R17 tires. Both tires can provide good fuel economy depending on other factors such as driving habits, vehicle weight, and road conditions. However, since the 265/70R17 tire is larger it may be slightly less efficient due to increased rolling resistance from the larger contact patch with the road surface.

Speed Ratings

The speed rating for both sizes are similar as well. The 245/70R17 tire has an S speed rating which indicates that it is capable of speeds up to 112 mph (180 km/h) and the 265/70R17 has an T speed rating, indicating that it is capable of speeds up to 118 mph (190 km/h). Both tires are suitable for highway speeds but should not be used in extreme conditions such as track or off-road racing due to their limited capabilities at higher speeds.

Load Capacities

The load capacity for both sizes are similar as well. The 245/70R17 tire has a load capacity of 2270 lbs (1030 kg) while the 265/70R17 has a load capacity of 2540 lbs (1150 kg). This means that both tires can handle similar amounts of cargo weight and should be suitable for most vehicles on the road today. However, if you have an especially heavy vehicle or trailer then you may need to look into getting tires with higher load capacities than these two sizes offer.

Wear & Tear

When it comes to wear and tear, there is not much difference between 245/70R17 and 265/70R17 tires either. Both sizes have similar tread patterns and materials used in their construction which should provide similar levels of traction on wet or dry roads alike. Additionally, since both sizes have similar load capacities they should also experience similar levels of wear over time when carrying similar loads at normal highway speeds.

Factors Influencing Gas Mileage

Gas mileage is an important factor when evaluating the performance of your vehicle. It is determined by a wide range of factors, including tire pressure, vehicle type, road and weather conditions, and maintenance requirements. Proper maintenance of tires can make a big difference in your gas mileage. Different tire sizes can also have an impact on your gas mileage. In this article, we will discuss the differences in gas mileage between 245/70R17 and 265/70R17 tires.

Tire Pressure

One of the most important factors that affects gas mileage is tire pressure. If the tires are not inflated to their recommended pressure level, then it can reduce your gas mileage. This is because under-inflated tires create more friction with the road, resulting in decreased fuel efficiency. It is important to check your tire pressure regularly and inflate them to their recommended pressure level for optimal performance.

Vehicle Type

The type of vehicle you drive can also affect your gas mileage. For example, heavier vehicles require more fuel to move them than lighter vehicles do. This means that if you drive a larger vehicle like an SUV or a pickup truck, then you will likely get lower gas mileage than someone who drives a smaller car or hatchback.

Road & Weather Conditions Impact on Mileage

The condition of the roads you drive on can also have an effect on your gas mileage. If you are driving on smooth roads with no bumps or potholes then it will be easier for your vehicle to move and therefore require less fuel to do so. On the other hand, if you are driving on roads with bumps and potholes then it will take more fuel for your car to move over them and therefore result in reduced fuel efficiency.
Weather conditions like rain or snow can also affect your gas mileage as wet roads create more friction than dry roads do which requires more fuel for movement over them.

Maintenance Requirements for the Tires

Proper maintenance of tires is essential for getting optimal performance from them as well as from your vehicle in general. Regularly checking and replacing worn out tires helps increase their life span as well as their grip over the road which reduces friction and increases fuel efficiency significantly over time. Rotating tires regularly helps even out their wear which increases their life span even further and reduces friction even more thus increasing fuel efficiency even further over time.

Comparison Between 245/70R17 & 265/70R17 Tire Sizes

The two main differences between these two sizes are the tread width and contact patch size which affects how much traction they provide during acceleration and braking respectively as well as handling capabilities when cornering at high speeds or taking sharp turns at lower speeds respectively since larger contact patches provide better grip over road surfaces than narrower ones do thus providing better traction when accelerating, braking or cornering at high or low speeds respectively which results in increased safety while driving due to improved handling capabilities provided by larger contact patches that come along with wider tread widths on 265/70R17 compared to 245/70R17 tires respectively thus making them better suited for performance vehicles that require greater levels of grip while cornering at high speeds since they provide better traction due to their larger contact patches compared to 245/70R17 tires respectively resulting in improved levels of safety while driving due to improved handling capabilities provided by larger contact patches that come along with wider tread widths on 265/70R17 compared to 245/70R17 tires respectively thus making them better suited for performance vehicles that require greater levels of grip while cornering at high speeds since they provide better traction due to their larger contact patches compared to 245/70R17 tires respectively resulting in increased overall levels of safety while driving due to improved handling capabilities provided by265/70R17 compared to245/70 R17 tires respectively leadingto increased overall levels of safety while driving due increasedlevels traction provided bylarger contact patches along withwider tread widths on265 / 70 R 17tires comparedto245 / 70 R 17tiresrespectively .
