Do you want to buy 205 40 R17 tyres online?
Welcome to Superior Cars in Northampton.
205 - this number stands at 205/40 17 for its width. The width is measured in millimetres when the tyre is on a rim. It must not be loaded during the measurement. Because a rim can deform a tyre somewhat and because the tyre can not be machined to millimetres accurately, it is an approximate value. Such a tyre can also be 206 mm wide. This does not matter because the next tyre size is 215/40 17.
Low profile strip with 40% flank height
The tyre height can not be shown in millimetres. However, it can not be found directly in the tyre detection. The second number is rather the tyre profile, which tells you a little bit about the percentage of tyre width and height. For a 205/40 17 tyre, the height of the tyre flank is thus calculated from this calculation: 205 mm multiplied by 0.4 (or 40 percent) = 82 mm. With such a low tyre profile, this tyre is one of the low-profile tyres. It also has an internal radius of 17 inches, which can be seen in the third figure. This value is also important when buying a rim because the tyre must fit naturally on the rim.
