  • recalibrating speedometer

    Quick question, I am planning on taking my stock 16x8 tires off and replacing them with 17x9.
    Do I need to recalibrate my speedometer?

    I did that same swap and didn't re-calibrate the speedo. I'm not sure if you have to. I'm going to get my alignment in a couple of days, i'll ask the guy there if you should.

      What size of tires did you have previously? Just type both sizes in here and you will know by how much you are off.

      What kind of wheels you getting?

        thanks for the info. It looks like if we do get the new wheels, we will be driving 2% slower than what the speedo shows. I like that. We were thinking about getting BFGoodrich g-Force T/A KDWS

        oh wheels, oops, we are getting the ZR1s chrome
