- Which of the following statements about sidewall markings is correct? a. The load index is given as a letter. b. The traction and temperature ratings are based on the speed rating of the tire. c. The tires recommended inflation pressure and load are indicated. d. The DOT code indicates when and where the tire was made.arrow_forwardHow does a technician determine the proper inflation for a vehicle's tires?arrow_forwardTechnician A says that replacement wheel rims should be the same as the original equipment wheels in load capacity, offset, width, diameter, and mounting configuration. Technician B says that if wheels are installed that have a different stock width or diameter, make sure to use a tire that has the same overall width as the original tires. Otherwise the vehicles wheel-speed sensors, speedometer, antiock brake system, and many other systems will be affected. Who is correct? a. Technician A only b. Technician B only c. Both A and B Neither A nor Barrow_forward
- A front tire has excessive wear on both edges of the tire tread. The most likely cause of this problem is ______. a. overinflation b. underinflation c. improper static balance d. improper dynamic balancearrow_forwardwhat is the formula to measure gas from tire interior?arrow_forwardAn indirect TPMS is being discussed. Technician A says that if a specific tire is low, the system will typically alert the driver which tire is low. Technician B says that after serving the indirect TPMS, you need to perform a re-learn procedure. Who is correct? Technician A Technician B Both Technician A and B Neither Technician A or Barrow_forward
