1. A tire company is creating a new tire for a motorcycle to drive off-road in sandy and rocky conditions as well as on roads. Engineers developed three different tread patterns. Based on the engineering design process, the next step the company should take is to:
Send out a questionnaire about tires to the public
Select which tread design will be best
Research the properties of rubber
See which tire is the most expensive
