Stock 9X16 rear wheels, what are you guys running? speedo is now off.

I just got a new set of rears 245/45 , I previously had 245/50's on there, so the lower profile is a smaller tire altogether.

My speedometer is no longer accurate which I was expecting. It's about 10% off now.

I know the 245/45 is the stock tire size, but I'm just curious if you guys runs something else. Maybe the PO had the speedo calibrated to the larger tire size?

Mine has the 245/45 stock size and the speedometer is off anyways. It always reads faster then what I'm actually going. For example, I passed one of the radar speed signs and it was about 5mph slower then what my speedometer said. So by going to a smaller size would make it off even more.

Ditto here - I'm running SO3 245/45x16's and my speedo reads about 10% faster than my GPFS says I'm actually travelling.
