What size tires are on a 2014 Lexus RX350?

The common tire size for a 2014 Lexus RX350 is 235/65R17 on 17-inch wheels, while models with 18-inch wheels use 235/55R18. Check your vehicle’s door jamb placard to confirm the exact size for your specific trim and configuration.

The tire size on a 2014 RX350 depends on the wheel diameter installed by the factory for that trim or option package. Sizes can vary if your vehicle has aftermarket wheels or a different option package. For exact specification, refer to the placard in the driver’s door jamb or the owner’s manual.

Tire sizes by wheel option

The following sizes reflect the common factory configurations associated with the RX350’s wheel options for 2014. This helps guide tire purchases and replacements.

• 17-inch wheels: 235/65R17


• 18-inch wheels: 235/55R18

If your RX350 uses a different wheel size (for example, aftermarket 19-inch wheels), the tire size will differ. Always verify the exact size against the vehicle’s placard before buying tires.

How to verify your exact size

The most reliable source is the tire information placard on the driver's door jamb. It lists the recommended tire size(s) for both front and rear tires and the suggested cold inflation pressures. You can also read the tire sidewall to confirm the size code currently installed on the vehicle.

Understanding the size code

Tire size codes such as P235/65R17 decode as follows: P = passenger vehicle, 235 = tire width in millimeters, 65 = aspect ratio (sidewall height as a percentage of width), R = radial construction, 17 = wheel diameter in inches. Matching these numbers to the factory specifications ensures proper fit and performance.

Summary

For a 2014 Lexus RX350, expect 235/65R17 tires on 17-inch wheels or 235/55R18 tires on 18-inch wheels, depending on the trim and options. Always confirm the exact size with the door placard or dealership, especially if your vehicle has non-standard wheel configurations. Ensuring the correct tire size supports proper handling, speedometer accuracy, and ride quality.
