What size wheels are on a Lexus IS350?
In most Lexus IS350 models, wheel sizes range from 17 inches up to 19 inches, depending on year and trim; common factory sizes include 17x7.5, 18x8, and 19x8.5 wheels, with some models using staggered setups.
Overview: The Lexus IS350 has evolved across generations, and wheel size is a function of model year, trim level, and optional packages. This guide explains typical sizes by generation and how to verify the exact specification for a specific vehicle.
Wheel sizes by IS350 generation
First generation (2006–2013)
For the original IS350, wheel sizes were typically 17 inches as standard, with 18-inch wheels offered on higher trims or via optional packages.
- Standard: 17x7.5 inches with traditional 225/45R17 tires (varies by market).
- Optional: 18x8 inches with around 235/40R18 tires on select trims/packages.
- Notes: Some markets or special editions may have different but closely related sizes; overall, 17–18 inches were common in this generation.
In this generation, buyers frequently encountered 17- and 18-inch wheels depending on the trim level and whether the vehicle had a preferred or performance-oriented package.
Second generation (2014–2017/2018)
The 2014–2017 IS350 offered a similar range and continued to use 17-inch wheels as a baseline, with 18-inch options widely available, and some sport-oriented trims incorporating 19-inch wheels.
- Standard/base: 17x7.5 inches with tires in the mid-size range (e.g., 235/45R17).
- Higher trims/Packages: 18x8 inches with 235/45R18 tires.
- F Sport: 19x8.0–19x8.5 inches depending on the sub-trim, typically paired with performance-oriented tires (e.g., 235/40R19).
By this generation, 17–19 inch wheels became a common spectrum, with sport-focused variants skewing toward larger diameters for enhanced handling and aesthetics.
Third generation (2019–present)
In the current generation, IS350 wheel sizes generally span 17–19 inches. Base models tend to use 17-inch wheels, higher trims often come with 18-inch wheels, and F Sport/Performance-oriented trims commonly ride on 19-inch wheels.
- Base: 17x7.5 inches with 235/45R17 or similar tires.
- Mid-level trims: 18x8 inches with 235/45R18 tires.
- F Sport/Performance: 19x8.5 inches with 235/40R19 tires (some markets use 19x9 in certain packages).
As with earlier generations, exact sizes vary by market, trim, and optional packages. The presence of 19-inch wheels is most common on sport-oriented or higher-end trims.
How to verify the exact wheel size for your IS350
The most reliable way to confirm your vehicle’s wheel size is to check the information placard on the driver’s door jamb, which lists the wheel diameter and tire size. You can also consult the owner’s manual or the vehicle’s original window sticker (Monroney label) when available. If you’re looking at a used IS350, verify the VIN with a dealer or Lexus customer service to confirm factory specifications, as owners may have swapped wheels after purchase.
Summary
Across its generations, the Lexus IS350 has commonly used wheel sizes in the 17–19 inch range. The exact size depends on the model year, trim, and optional packages, with 17-inch wheels typical on base models, 18-inch wheels on many mid- to upper trims, and 19-inch wheels reserved for sport-oriented variants.
