tire size and speakers 200 1989

i did the math on smaller/larger tires the other day and basically you take the radius difference and multiply that by 2 x pi. factoring in that the tire is about 24 inches diameter, a one inch difference adds up to about a 4% difference in speedo reading. which is 2 mph off at 50mph. maybe not too much of a concern.
