2 tire lines. 38x15.50R18 tires sized to your wheels and your car.
38x15.50R18 is a flotation size: 38 inches tall, 15.50 inches wide, on a 18 inch wheel. In metric it is 394/64R18, which is how the catalogue stores it. Whether 38x15.50R18 works comes down to the wheel width it mounts on and how far it lands from the height the car left the factory with.
2 lines carry 38x15.50R18, from 2 brands (Nitto and Toyo). 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 38x15.50R18 lines that do both.
