Hey sorry I just saw this message now. It does throw it off by a a few MPH but not much. There's a site somewhere that jhas you type in the current and new sizes and then tells you how off it will be. It does slow the car down though due to the added weight.

hey,
I have a question about your acura. I love the wheels that you currently have. I'm looking into wheels for my 2004 Acura TL 6M. I know that the wheels are 19inches and that they require a 15mm spacer. Question: do the size of the wheels make the speedometer off? My friend had always told me that if the car didn't come with anything greater then an 18 don't do it because it throws off the tach. THanks in advance and man i would love to have your car. Your caught my eye because mine is the same color.
