Hey guys! I just had a question regarding wheel sizing. My winter tires are 16” 215/55R but I have no idea what the offset and width should be. I wanted to replace my steelies after realizing how much I liked the oem Honda rims in comparison to steelies in the winter.
I appreciate your help,
Thanks!
The specs for the factory 16's are: 16x7, offset of 45 with a 215/55-16 tire (diameter of 25.3 inches).
17 inch wheels are 17x7 offset 45 with a 215/50-17 tire (diameter 25.5 in)
18 inch wheels are 18x8 offset 50 with a 235/40-18 tire (diameter 25.4 in)
All 11th gen civics except for the Si and Type-R, can downsize to a 15 inch wheel using a 205/65-15 (25.5 in diameter) winter tire on a 15x6 wheel. I personally would recommend a 205/60-16 (diameter 25.7in) on a 16x6.5 wheel for an ideal balance of stability and narrowness for best winter traction. I am currently using a 205/55-17 (diameter 25.9in) on a 17x7 as that is what I had leftover from my 2020 Si. It should be noted that 215/55-16 stock size tires are perfectly adequate for most if not all winter needs when using a high quality winter tire. I only go with narrower sizing because I live in northern New England and the narrow casing width helps with getting the tread through the snow and slush.
If you stay within the parameters for offset and width you should have no handling or fitment issues. Keep your winter conditions in mind when you buy winter tires, some environments don't require a full on studded Nokian but rather a non-studded "friction" tire ie: Blizzak, MIchelin X-Ice, or Hakka R3/R5. nor do they always require a drastic -1, -2, or -3 wheel sizing change. For the most part you will do fine with any winter tire in the stock size.
