How about you take the money you're about to spend on those rims and purchase some taste? Are you kidding me? 20's on an Accord? Why don't you paint up a sign that says "Hi, my wheels cost 1/4th the price of my car. I've got jacked up priorities." and just stick it on the side of your ride?
Your 20s are going to rub on your wheel wells more than I like to rub my genitals throughout the day when I get bored here in my cube. Not to mention it's going to look ridiculous. The most you should even think about putting on an Accord is 18s to avoid looking like you are trying to be all bling bling in your $20K vehicle. You are trying to fake the funk and they should give citations out for it. Not that Accords aren't nice cars...they're just not 20 inch rim nice. You put 20s on an upscale SUV like an Escalade, Navigator, X5, or Range Rover. 20s will actually fit on them and not look like you're riding around on four oversize unicycles with a big box ontop of it. 20s belong on a Lexus LS, GS, BMW M5, Benz S500 or CL500/600 or SL.
