Not sure what size of wheels you are indicating there but any wheel / tire combination the alters the circumference of your tire from factory will affect your speedo reading.

You need to do what is called a "plus one" conversion. This is where you buy an 18 inch rim but you get a tire that is one inch of lower profile.So the overall heighth of your tire is the same but your running bigger rims.
This will look great and your speedo will stay correct.Plus your not losing gear ratio, and braking power. :cool:
