Hey guys. I am new here and had a question about rims. I'm looking into buying a 2005 Civic EX Coupe SE, however in the event that I do those tiny stock rims will have to go. I am hoping to fit 18 inch rims with a width of 7.5" and an offset of +42 onto the car, however I have no idea what the cars max size would be. If anyone could give me an idea as to whether these will fit, I'd appreciate it. Also, what size tires would I need to clear the fenders?

Go here and compare your stock tire size, to your 18. The wheel dimentions you have listed are PERFECT!
