1 tire line. 33x11.50R20 tires sized to your wheels and your car.
33x11.50R20 is a flotation size: 33 inches tall, 11.50 inches wide, on a 20 inch wheel. In metric it is 292/57R20, which is how the catalogue stores it. Whether 33x11.50R20 works comes down to the wheel width it mounts on and how far it lands from the height the car left the factory with.
1 line carries 33x11.50R20, from Nitto. 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 33x11.50R20 lines that do both.
