What does 205 55 15 mean?
R15 tires have a diameter of 23. The sidewall of the tire is 4. This means a 205/55R15 tire will make make 845 revolutions per mile, or 525 revolutions per kilometer. All tyres have a size marked on the sidewall, for example, 205/55 R16, the number 55 is the aspect ratio and indicates the height is 55 percent of the width of the tyre. Tyres that have an aspect ratio of 50 or less would be classed as low profile tyres.R18 tires have a diameter of 29 (737 mm), a tread width of 10 (255 mm), and a wheel diameter of 18 (457. The sidewall of the tire is 5.For example, if a tire is marked 205/55 R16, its section width is 205 mm and its sidewall height is 55% of the section width. The main difference between 55 sidewall and 60 sidewall tires is the difference in sidewall height. The 55 sidewall offers a lower profile, while the 60 sidewall has a higher profile.
What does the number 205 55 mean?
The first number (205) tells you the width of the tyre in millimetres. The second number (55) tells you the height of the tyre as a percentage of the width. The letter (R) stands for “Radial” which is the type of tyre. The number (16) tells you the size of the wheel rim in inches. R represents the carcass construction (radial) 17 is the wheel diameter (inches) 105 is the load index.The size ends with the load index 91, which is the maximum weight that each wheel can support, and the speed rating H, which is the maximum speed at which the tire is approved for use.
What is the difference between 205 55 and 205 60?
So on a 205/60 tire the sidewall dimension will be 60% of the 205 width in millimeters. On a 205/55, the sidewall is going to be 5% shorter resulting to slightly smaller overall wheel diameter making your speedometer read slightly faster than your actual speed, but it won’t be much so don’t worry about it. A tire with an aspect ratio of 60 will have a taller sidewall than a tire with an aspect ratio of 55. This means that the tire’s height will be greater, which could affect the speedometer reading and the overall handling of the vehicle. However, the difference between the two aspect ratios is minimal.Aspect ratio If the value is 70, the tyre’s height is 70% of its width. Typically an aspect ratio of 55% and less indicates a low-profile tyre.Up-sizing, or installing a taller tire, will lead to a speedometer reading that displays slower than your actual speed. This is because a taller tire will have a larger overall circumference, causing it to need to travel more distance per revolution than the original equipment tire.So on a 205/60 tire the sidewall dimension will be 60% of the 205 width in millimeters. On a 205/55, the sidewall is going to be 5% shorter resulting to slightly smaller overall wheel diameter making your speedometer read slightly faster than your actual speed, but it won’t be much so don’t worry about it.
What does 205 55 R17 mean?
The tyre size “205 55 R17” is a common tyre format broken down as follows: 205: The tyre’s section width in millimetres, indicating the width from sidewall to sidewall. The aspect ratio, the sidewall height as a percentage of the tyre’s width. Here, it’s 55% of 205 mm. No, for most cars a tire pressure of 40 psi is too high. You might find 40 psi suitable for some vehicles, especially if they’re carrying heavier loads or if the manufacturer’s recommendation is close to that figure. However, it’s generally too high for most passenger cars, which usually recommend between 30-35 psi.However, as a general guideline, the recommended tyre pressure for 205/55 R16 tyres typically falls within the range of 30 to 35 PSI (pounds per square inch) for passenger vehicles.Yamaha R15 tyre size The latest version of Yamaha R15 comes with a 100/80-17 tyre at the front and a 140/70 R17 tyre at the rear.If you are looking for supreme quality, great tyre stability, and excellent steering control for your vehicle, then 195 65 r15 tyres should be your ideal choice.

What does the 55 mean on tires?
This second number actually represents the height of the sidewall expressed as a percentage of the width of the tire. So in our example image, this tire has a width of 235 millimeters, and the 55 indicates that the tire height is 55% of the width or 129. The first number in the tire size, 205, represents the width of the tire in millimeters. To convert this to inches, we divide 205 by 25. This gives us approximately 8.The first sequence – 225/55 – indicates the width in millimetres of the tread that is in contact with the road (225) and the height of the side wall as a proportion of the width (55%). The next – R18 – specifies the construction of tyre (R=radial) and the diameter in inches (18) of the wheel on which the tyre fits.For example, in a 205/55/16 tire size, 205 is the tire width and 55 is the sidewall height. In this case, the difference between a 55 sidewall tire and a 60 sidewall tire is the difference in sidewall height. So, the difference between a 55 sidewall tire and a 60 sidewall tire is 5 mm.This number refers to the section width of the tire, measured in millimeters from sidewall to sidewall; thus, a 255 tire is 10mm wider than a 245 tire.
