Factory tire sizes by wheel diameter
Here are the typical OEM tire size ranges you may encounter depending on the wheel option on RX350 models.
- 18-inch wheels: 235/55R18 (all-season tires)

These sizes can vary by production year and market, so always verify the exact specification on the vehicle’s door jamb placard or in the owner’s manual.
OEM tire brands and models
The original equipment tires for the RX350 are typically from premium brands; the exact brand and model depend on year, trim, and country. Commonly used brands include Michelin, Bridgestone, and Continental, among others. The door placard will list the specific tire brand and model for your vehicle.
- Michelin (various Primacy MXM-series models are often seen on RX350)
- Bridgestone (Dueler series is commonly represented in several markets)
- Continental (CrossContact series appears on some production runs)
Because the tire lineup can change with model years and regional specifications, always confirm the exact brand and model from the placard or your dealership when replacing tires.
Replacement considerations
When replacing RX350 tires, it’s important to align with the factory recommendations to maintain handling, comfort, and warranty. Consider the following.
- Match the OEM size from the door placard to preserve handling and speed rating
- Choose all-season tires for year-round use, or add dedicated winter tires in snowy regions
- Decide between standard tires and run-flat options if your model supports run-flat tires
In practice, the right replacement tires should mirror the OEM size and type to ensure balanced performance and to avoid ride or safety issues.
