the change in speed will be the change in the circumference of the tire. The circumference will be the diameter of the tire times pi. divide find the circumference in feet, then divide by 5280, giving you miles. now, you have to do that for both tire sizes, and take the difference. if i am thinking correctly, then you won't have to worry about dividing by hours because both sides are, it's just the difference. if anyone has any disputes, i haven't taken physics for two years, so i'm a little rusty. check me if you know.
