Sorry to say, I don't have a gallery of pics on this site. I dunno why, I just refuse to use them but I don't mind sending pics upon request.

Isn't 205/60-15 the best size for Si wheels? They are less than 1% off from the stock size, speedometer-wise, while 205/55-15s are 2.25% off. I would want to stick with the closest size to stock, even if the sidewall is a little thicker.

to tell you the truth with the 205/55 my spedo is off by less than 4mph (4 mph fast)

actually its a %. Like my 205/50-15s are about 5% off. So when my spedo says Im going 100 I'm really only going 95. where as if the spedo say Im going 65 I'm really going 61.75mph.
