Speedometer way off

I have a '95 Del Sol S. My speedometer is off, when it says I'm going 75 I'm only going 68.3. I just put new tires on it and they are the size specified in the owners manual as Factory Stock. Is there a way to adjust the speedometer?

Thanks,

Are you using the stock wheels?

go to the dealership and see if they can recalibrate it.. do you have aftermarket gauges or anything? I messed up my speedo BAD putting on aftermarket gauges on my old car. Said I was going 57 when I was really going like 70 (Sorry officer!). I had the dealership recalibrate it, problem fixed.

Everything is stock, thanks for the recalibration tip.
