After talking to a friend who sells auto parts he said that my 06 accord sedan ex bolt pattern is 5x115 and not the 5x114.3 that the websites have been telling me so can I run 5x114.3 2013 civic si wheels or is it a bad idea? and would I need anything else like hub centric rings or spacers? Plz help

 

The bolt circle is 5 x 114.3mm.

As far as spacers, that depends on the offset of the wheels. Your offset should be 38 to 48 mm. I'm not sure what the offset is on the Civic wheels.

As far as hub-centric rings, the center of the wheels should be a 64mm bore. I think that Civic wheels will be the same. Are you talking about the stock wheels from a 2013 Civic Si?

 

If your friend is correct, and your Accord has a 5x115 bolt pattern, then you should be able to use 2013 Civic Si wheels without any issues. You may need hub centric rings or spacers, but it depends on the exact dimensions of the wheels you're using. I would recommend checking with a qualified technician or automotive specialist to be sure.
