I recently purchased the 98 in my sig, and it came with a set of Hankook Dynapro ATM 235 85R16 tires on it. I looked at their site, and it shows that tire to be 31.7" as opposed to the stock tires that it mentions on the drivers door of 245 75R16...which are showing 30.5.
I'm sure my speedo is out of whack...so I'm curious how I get it back to where it should be? I know on my 06 they can just electronically adjust, but how do they do it on a 98 12V?

 

Also done electronically, with a DRBIII scanner. If you're ever down south, JHansen in Delia could do it for you, as he has a scanner. Or just go to the dealer. Cost me $50 on my dually. Jason did it for free for me on my 12v.

 

Thanks again, Tate. Appreciated!
