"dont get bigger tires... it will throw off your speedo", i beg to differ Options

[lagos]

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

I had smaller tryers on my old car and they put the speedo out by 10%
at 110km/h i was realy traveling at 100km/h
alot faster take off by the way

also with bigger tyers you should be able to fix this with some resistors in the speedo wire, shouldn't you.
but can i ask why you want bigger tyers just for looks.
