You need to provide the profile size.



Use the calculator at:

You forgot something! The middle number will tell us the answer. Is it 45, 50, 55, 60, 65 or 70? Even an old woman like me knows there is a middle number.
i need to know the sidewall off the tire. your tire will say stock 225/?/18 and new will be 245/?/18.
I'd say 60 is still just about 60. The change from 225 to 245 is a change in tire width, not diameter. Speedo readings won't be affected.
easist way to be sure, is just try it out.



Either go through a measured mile, have someone pace you, or get a gps/nav-they all usually have speedometer function that is pretty accurate (especially at higher speeds)
it might not or it might i went from r15 265 to a r16 44x19.50 and it was only 5 mph off so it just depends take it some engine electronics place and have them set it correctly
