What size tire is a 215 55R16?
R16 tires have a diameter of 25. The sidewall of the tire is 4. This means a 215/55R16 tire will make make 798 revolutions per mile, or 496 revolutions per kilometer. Tire Number Meaning: Size For example, 215/55R17 91V means: 215 – This is the tire’s width in millimeters from sidewall to sidewall. This is the aspect ratio, which is the tire’s sidewall height as a percentage of the tread width. R – This indicates the tire construction (“R” means radial).
Can I put 55 tires instead of 60?
It’s highly recommended to use the exact tire size recommended for your car. However, in a pinch the tire width and aspect ratio can be changed slightly and still fit on your rim. Although this will still work, keep in mind it may have adverse effects on the performance of your car. It has often been said that to have good cycling wheel performance, there is a rule that the external rim width of a wheel should be at least 105% of the width of the tyre, or that there is a simple relationship/formula that will predict the aerodynamic performance of a wheel based on rim width vs tyre width.
What does 215 mean on tyres?
Using our example again, 215/60R16 95V, 215 means that the tyre is 215mm wide from the inside to the outside edge across the tyre tread. The profile, otherwise known as the aspect ratio, is 60 in our example. In this case, the only difference is the aspect ratio, which means the height of the sidewall will be 55% of 215 mm instead of 60%. That’s 118.
