for some reason my speedo isnt reading correct, atleast according to a couple speed sign thingys. everytime i drive by a couple of those speed signs, the speedo dosnt match up with the speed on the sign. its not just one sign, but a couple of em. say if my speedo reads im going 30mph, the sign will say im goin 27...i have to correct tire size(195/50R15 Kumho ECSTA Supras) but for some reason the speedo is off. any idea as to why?

thanks!

 

just so you dont worry ... your speedo isnt always correct its an aproximation just like the sign thing .. ,i drive by them all the time tells me im going about 2 over or 2 under almost ever time ..

lol

unless i have the same problem as you i wouldnt worry

 

all honda spedo are a little off!! dont worry!!!

 

mines is off by like 8-13 mph

 

mine is crazier it goes back werds from 0 - 100 then down hah

 

All Honda and I believe all vehicles speedos are off. I have the speedo showing 190km/h when Power FC commander showing only 172.

and please dont ask me where I did that...

 

All the speedos are wrong to a degree. Better that they're high than low though.

 

o alright. i wasnt too concerend about the 3mph difference, just wondering if it would throw my odometer off. but i guess its no biggie. thanks everyone
