I've got an '03 EX with stock 4-lug steel rims. The tires are 185/65 R15. I'd like to replace them with oem rims and have been watching craigslist and ebay. I read the FAQ threads and saw the tire/wheel calculator chart but I'm still lost. I found some on craigslist from an '02 Accord that says they'll fit any Honda four bolt pattern. What is meant by '15x6' or 115m bolt pattern specs? What year/model rims will fit the '03? Thanks for any help.

 

The 03 model needs a 4x100 rim. This means that it is 4 lug and that the holes are spaced 100mm apart. Only a 4x100 rim will fit. If you saw one that is 4x115, that means that the holes are spaced too far apart for your car. Civics of that era were 4x100, and Accords (being bigger) were 4x114.5 or something. 15x6 means that the rims are 15 inches across and 6 inches wide. This is a good size for that car.

Pretty much anything from 88-05 will fit your car. But because your car is from the 2001-2005 generation, a 14 inch rim will look small and a 15 inch is just about right, but will still have a good sized gap.

I would recommend looking for a "Civic Si" rim. It's clean and was used from 99-00 on Civic Si's and 03-05 on EXs, I think. It's 15x6 and would run well with a 205/50/15 tire. A 195/55/15 can be substituted. The stock 185/65s are, in my opinion, just too narrow.

[edit] the rims in my sig are Civic Si rims. Clean and stock.

 

The 2005 Si came with 205/55/16s (although some did come with 17-inch wheels) on 16x7 wheels. If that size fits, I think they's look better than the 15s.
