Yes the tires will fit on the rim. You are not changing the width of the tires so it is unlikely that you will have any fitment issues. Most tires have an will generally fit an select wheel width.
What’s the difference between 225 50R17 and 225 55R17?
Usually the lower the two-digit number, the wider the tire. The three digits (225) following the service type, tell us the cross-section width of the tire in millimerters. In the example, the 50 width tire will bethe wider tire, whiler 55 will be slightly taller.
What is the difference between 225 65r17 and 225 55R17?
The difference in the dimension of the two tyres is purely in the aspect ratio of the sidewall so the /65 tyres will have a bigger sidewall (note that the number is 65% of the width, not 65 somethings – i.e. 165.75mm vs 140.25mm and that’s effectively doubled because you’re taking radius, not diameter) and therefore
