so, for years ive always had people say to stay with low profile tires, because anything bigger will throw off your speedo. im sure we've all seen the online calculators and countless threads. ive even had tirerack call me back and try to convince me to change my order from 225-45-17s to 205-40-17s because of this..lol ...
well anyway, i just wanted to say that all that, is mostly a myth. i recently got a gps for my car. my speedo is dead on with the mph reported by the gps. i was a bit shocked because i expected it to be off by at least 1-3mph. so go ahead, get bigger tires and enjoy the ride quality..your speedo will be just fine

The spec when setting a speedo is if you want it to display 20 mph then you can set it when the it is reading anywhere between 18 - 24 mph. So yours might have been close to correct but your tires have put you into the upper range. Also the speed readings from a gps aren't exact.
