42 tire lines. 245/75R16 tires sized to your wheels and your car.
A 245/75R16 is 245 mm wide with a 184 mm sidewall (75 series) on a 16 inch wheel, 30.5 inches tall overall. A tire size only makes sense next to a wheel width and a car. 245/75R16 mounts on a range of widths, and the overall height decides whether the speedometer and the fender stay happy.
42 lines carry 245/75R16, from 12 brands (Falken, Hankook, Toyo, Yokohama and 8 more). By type that is 23 all terrain and 13 highway. The tire has to stay near your car's stock height and mount on your wheel width, so pick the car and the wheel set and the page keeps only the 245/75R16 lines that do both.
