19 tire lines. 37x12.50R20 tires sized to your wheels and your car.
A 37x12.50R20 stands 37 inches tall and 12.50 inches wide on a 20 inch rim, the metric equivalent is 318/68R20. A tire size only makes sense next to a wheel width and a car. 37x12.50R20 mounts on a range of widths, and the overall height decides whether the speedometer and the fender stay happy.
19 lines carry 37x12.50R20, from 10 brands (Toyo, Nitto, Falken, Ironman and 6 more). By type that is 5 all terrain. 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 37x12.50R20 lines that do both.
