RESULTS:
As expected, the tires that claimed to have better tread and more traction took more force to move at first (see chart above) meaning that they would grip the road better than the tires with less traction and tread. Our results, in general, agreed with the predicitons made by the consumer reports about these particular tires. Thus the hypothesis that tires with more traction will have a higher coefficient of friction and thus will perform better under slippery and icy conditions was indeed correct.
