What size tires are on a Lexus 350RX?

There isn’t a single tire size for all Lexus RX 350 models. The correct size depends on model year and wheel package. The exact size is listed on the door jamb placard and the tire sidewall.

How to determine the exact tire size for your RX 350

To identify the exact size, check these sources:

• Door jamb placard on the driver’s side that lists the recommended tire size for the vehicle as equipped from the factory.


• Tire sidewall markings on one of the installed tires, which show the size sequence (for example, P235/60R18).


• Your vehicle’s owner’s manual or the official Lexus site/VIN lookup for year- and trim-specific specifications.

Using these sources will confirm the correct size and help you avoid mismatched tires or wheel-fit issues.

Reading tire size markings on the sidewall

Tire size markings on the sidewall follow a pattern such as P235/60R18. The first number is the tire width in millimeters, the second is the aspect ratio (height of the sidewall as a percentage of width), the "R" denotes radial construction, and the final number is the wheel diameter in inches. This is useful when you’re comparing replacement options to your current tires.

Common RX 350 tire sizes by wheel diameter

Note that sizes vary by model year, trim level, and market. The examples below reflect typical stock configurations you may encounter on many RX 350 models with different wheel sizes.

• 18-inch wheels: commonly 235/60R18


• 19-inch wheels: commonly 235/55R19


• 20-inch wheels: commonly 235/50R20

Keep in mind that specific trims or regional variations can shift these sizes. Always verify with the door placard or VIN-specific data before purchasing tires.

What to consider when replacing tires on an RX 350

Before buying tires, ensure compatibility with your vehicle’s drivetrain and performance needs. The following factors influence the right choice beyond just size.

• Match size exactly to the manufacturer’s specification for the vehicle’s trim and drivetrain (AWD/2WD).


• Use the correct speed rating and load index appropriate for your vehicle and driving conditions.


• Consider warranty, wear life, and regional climate when selecting all-season, summer, or winter tires.

If you’re unsure, consult a Lexus dealer or a qualified tire professional to avoid affecting handling, traction control, or the AWD system.

Regional differences and model-year updates

tire sizes can vary by market (for example, North America, Europe, and Asia) and by model-year updates. Always check the exact specification for your car using the door placard or VIN-based documentation to confirm the stock tire size for your specific vehicle.

Summary

The Lexus RX 350 does not have a universal tire size. The correct size depends on year, trim, and wheel package. To determine the exact size, review the driver’s door placard, inspect the tire sidewall, and consult the owner's manual or Lexus’s official resources. When replacing tires, match the manufacturer’s specified size and consider speed/load ratings, AWD implications, and regional variations. If in doubt, seek guidance from a knowledgeable technician or dealership to ensure proper fit and performance.
