Any law enforcement officer, at any time, upon reasonable cause to believe that the tires of a vehicle are unsafe or it is equipped with tires in violation of the provision of this section, may require the operator of such vehicle to stop and submit the tires of such vehicle to an inspection. If the inspection discloses the vehicle to be in violation, the officer may issue a summons for such violation. Operation of a motor vehicle or, as owner permitting the operation of a motor vehicle in violation of any provision of this section shall be an infraction.
