who would you write about?
If none of these work, you are out of luck my friend.
215 45 17 and 215 50 17 would be hard to see any different might be a half inch in width if that much as for price easy to just cal three tire stores and ask how much are your 215 45 17 and you didnt lower the car any if they are 215 then they same height. 45 to 50 is width and realy just about any tire wil do and none would be dangerous if you drive right and should be careful with speed bumps all the time and what hills have to do with anything im not sure ive been a tire guy 30 yrs
