46 tire lines. 235/45R18 tires sized to your wheels and your car.
A 235/45R18 is 235 mm wide with a 106 mm sidewall (45 series) on an 18 inch wheel, 26.3 inches tall overall. A tire size only makes sense next to a wheel width and a car. 235/45R18 mounts on a range of widths, and the overall height decides whether the speedometer and the fender stay happy.
46 lines carry 235/45R18, from 15 brands (Continental Tire, Falken, Michelin, Toyo and 11 more). By type that is 34 all season, 5 performance summer and 1 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 235/45R18 lines that do both.
