People before many of owners get excited and get rims. Please follow the technical standards and recommendations.
I posted all recommended tyre sizes and this data for Civic X earlier. This is a sample case scenario and notice that rims width and tyre have a range which is extremely important. Dont get a wider rim and narrower tyre which doesn't fall in recommended range or vice versa
In UK, an incorrect tyre as per rim width range fails for an insurance claim. Here is a screenshot from the MOT Guide.
A wider rim and narrower tyre or vice versa makes the fitting bead unstable. A cause of tyre failure as well
Following or not following standards is totally your right. Just giving info as per my knowledge
