How tall is a 175 65 15 tire?
Therefore, the tire size 175/65r15 can be expressed in inches as roughly 6. This is also known as the aspect ratio. The lower the number, the more ‘low-profile’ the tyre.The 215 means 215 mm wide. The 65 is a percentage meaning 65% of the 215 mm width.The 185/65R15 88H tyre has the following features: the first three digits 185 refer to the width of the tyre in millimetres. The second two-digit number 65 refers to the ratio between the height of the sidewall and the width of the tyre.
Which tire size is better for fuel efficiency?
Larger tires require more energy from the engine to move the vehicle compared to smaller tires, resulting in increased fuel consumption. Smaller tires and wheels demand less engine output, making them more suitable for navigating stop-and-go city traffic efficiently. Larger and heavier tires do offer advantages. Larger, heavier tyres increase rolling resistance, meaning your engine has to work harder to maintain speed. This directly translates to lower fuel efficiency, leading to increased fuel consumption and higher running costs.Any increase in wheel size will affect the rate that your vehicle can accelerate. This is because the larger wheels increase the overall weight of your vehicle, making it slower to reach those top speeds.When the tyre pressure is too high, the tyre is less flexible, resulting in a smaller contact patch with the road. This can lead to increased rolling resistance, which means the engine has to work harder to move the vehicle, leading to higher fuel consumption.One of the most notable advantages of larger tires is the extra height they provide. For off-roading enthusiasts, this additional clearance helps vehicles clear rough terrain and obstacles more easily. Higher clearance can also improve visibility on the road, allowing you to see further ahead.
