Measure the circumference of the tires of three different vehicles. Vehicles can include cars, bikes, scooters, tractors, etc.
Determine the number of full rotations the tires of each of the vehicles will complete in 10,000 miles.
Choose one of the vehicles and keep track of how far you travel in that vehicle for a week. Calculate the average daily number of rotations made by the tires.
Use your data to predict when you will need to switch the front and back tires.
