I need to buy two snow chains for my car with the size of 225 45R 19 (Nissan Qashghai 2016),

I have found a snow chain that fits:

225/45-18

225/50-17

225/55-16

So, will this snow chains fit the wheel of Nissan Qashghai, or I shall keep looking for a chain which fits the exact numbers (i.e. 225 45R 19).

Base on this [figure](http://kadawathatyrecentre.com/images/tyre_help.png) and my understanding, it seems the last set of numbers (inner rim) does not seem import, but would like to know the opinion of some experts (thanks)
