Speed Accuracy

[raphael_allen]

I just found this forum recently and I would like to ask the experts opinion here. I have changed my stock wheels of 205/70/14 (If i remember it right) for my Lancer 95. I got myself a 195/50/15. My wheels now are smaller than the stock ones, that I'm sure. I just wanna know what effect would it have on my stock speedometer? Lets say I'm running at 100kph on the gauge, whats the real speed that I have? more than or less than? thanks in advance.

If you have smaller wheels now, you'll be reading faster than you actually are running because the smaller wheels turn faster than the regular sized wheel.

when speedometer shows 100 kph, your actual speed is just about 90 kph
