I have just purchased new tires for my car.
I put on 205/50/15 to replace stock 195/65(60?)/15s.
With my wife driving her minivan in front of me, it appears that I have lost 10%
speed. I now have to go 120 to do 110. I love the tires and don't want to part with them! I can easily do the math in my head while driving, or I could set up a gps on my dash. But I would like to know how to recalibrate my speedo??
Any ideas?? There must be a way. I don't want to go with bigger rims this time.
Thank you all in advance.
Keep in touch!
