Re: Looking to change 2 tires with diferent size than Current Good or Bad???
You're taking .8" off your sidewall by doing that.. and like sam68 said, it'll throw your speedo off.. More specifically, it'll indicate you're going faster than you actually are (with your speedometer reading 60mph, you'd be actually traveling 56.1mph), and subsequently, your odometer would read more miles than actual.
Why would you wanna go with a smaller sidewall size? just wondering..
