Really appreciate the detailed reply buddy but in all honesty, if I was so well versed in the rims / tires domain, I wouldn't be asking such silly questions in first place 
I do understand tire dimensions but I have no idea what these % calculations and offsets mean 
I barely drive 30kms every day (work) and that too on clean and carpeted roads (mostly). So i'm not too concerned about the rims breaking etc. Not a big fan of Honda rims either.
What i'm concerned about right now is for a R17 size, should I get 215 / 55, 215 / 50 or 225 / 55?
If I opt for 215 / 55 or 225 / 50-55, will those hit the car / car shields while turning or driving?
Alternatively, If I go with 215 / 50 .. will that affect the ride quality?
Apologies for the lengthy post, I'm severely confused. Any help will be appreciated
