Are there guidelines on tyre and wheel rims?

You can find your vehicle's tire size on the Tire Label located on the B-pillar or edge of the driver's door. The Tire Label shows the original equipment size tires, the recommended inflation pressure, and the maximum weight the vehicle can carry, example below:

For advice on Tyre Specifications for your vehicle, please check your owner's manual by selecting the vehicle model from the Owner’s Manual Information section below and we will search the relevant Owner’s Manual for you.
