An 18 inch all terrain tyre must suit more than the wheel under it. Before comparing tread patterns, read the vehicle handbook and the tyre placard, usually found on the driver’s door pillar, door edge or inside the fuel flap.
Record the approved tyre sizes, load ratings, speed ratings and cold inflation pressures.
The placard may list more than one fitment, but those options are not automatically interchangeable with every aftermarket wheel. A quick photograph of the placard can prevent a second trip to the tyre shop, especially if the vehicle is being fitted out for a holiday or work assignment.
