Question

You don't have any values specified here but in general: Let L=length of street. Let d=diameter of tires.  We want to know the distance the wheel will turn in one revolution which is equivalent to the circumference of the wheel. $$C=2 \pi r ;\text{ or } C = \pi d$$where r is the radius and d is the diameter.  Once we have C, to get the number of times the tire revolves we use:$$N=\frac LC$$

Or$$N=\frac {L}{\pi d}$$
