What Does 285 65r18 tire Mean?
The 285 65r18 tire size is a bit confusing because it’s actually a little bit different. The first number, 285, is the tire’s width in millimeters. The second number, 65, is the aspect ratio.
This is the height of the sidewall as a percentage of the width. So, the sidewall height would be 65% for this particular tire size. The last number, 18, is the diameter of the wheel in inches. The “r” in this tire size stands for “radial,” which is the type of tire.
What Does 295 70r18 tire Mean?
The first number, 295, is the width of the tire in millimeters. The second number, 70, is the aspect ratio. This is the height of the sidewall as a percentage of the width. So, the sidewall height would be 70% for this particular tire size.
The last number, 18, is the diameter of the wheel in inches. The “r” in this tire size stands for “radial,” which is the type of tire. So, now that we know what each number in the tire size means, let’s compare the two sizes.
The first thing we’re going to compare is the tire’s diameter. The 285 65r18 has a diameter of 32.59 inches, and the 295 70r18 has a diameter of 34.26 inches. This means that the 295 70r18 is about 1.67 inches or 5.1% larger in diameter than the 285 65r18. This can make a big difference in the way your car handles. A larger tire will provide more traction and grip, making the car feel less stable.
Another important difference between these two tire sizes is the section width. The 285 65r18 has a width of 11.22 inches, and the 295 70r18 has a width of 11.61 inches. This means the 295 70r18 is about 0.39 inches or about 3.5% wider than the 285 65r18.
A wider tire will have more contact with the ground, leading to better traction. However, it will also create more drag and resistance, which can lead to poorer fuel economy.
The circumference of a tire is the distance around the outside of the tire. The 285 65r18 has a circumference of 102.37 inches and the 295 70r18 has a circumference of 107.63 inches. This means the 295 70r18 is about 5.26 inches or 5.1% longer in circumference than the 285 65r18.
A tire with a longer circumference will make your car’s speedometer read slower than your actual speed and make the odometer register fewer miles than you have driven.
Revolutions Per Mile
The number of revolutions per mile (RPM) tells you how often the tire goes around once. The 285 65r18 has an RPM of 618 and the 295 70r18 has an RPM of 588. This means that the 295 70r18 will make about 30 miles or 4.9% fewer revolutions per mile than the 285 65r18.
Sidewall height is the distance from the edge of the wheel to the top of the tire. The 285 65r18 has a sidewall height of 7.29 inches, and the 295 70r18 has a sidewall height of 8.13 inches. This means that the 295 70r18 is about 0.84 inches or 11.5%.
Rim or wheel size is the diameter of the wheel, not the tire. The 285 65r18 has a rim size of 18 inches, and the 295 70r18 has a rim size of 18 inches. This means that the two tire sizes can use the same size rims.
Radial tires are the most common type of tire. They are designed with steel belts that run radially across the tread. The 285 65r18 is a radial tire and the 295 70r18 is a radial tire. This means they are both designed with steel belts running radially across the tread.
If you are looking for a tire size that will work well for Jeeps, light trucks, and SUVs, the 285/65R18 is a great option. This size can handle well on and off the road, making it a good choice for any terrain.
