What size wheels for GS300?
The GS300’s wheel size varies by year and trim. In short, early models typically use 15-inch wheels, mid-generation cars commonly use 16- to 17-inch wheels, and some sport-oriented trims offer 18-inch wheels.
To confirm the right size for your specific car, check the owner's manual or the tire placard on the door jamb; the stock size is also stamped on the tire sidewall or documented in the vehicle’s build sheet. If you’re upgrading to aftermarket wheels, ensure compatibility for offset, brake clearance, and overall diameter to keep speedometer readings and handling accurate.
Stock wheel sizes by GS300 generation
First generation GS300 (1993–1997)
Early GS300s generally rolled on 15-inch wheels. Some late-year or specialty trims offered larger diameters, but the baseline remains 15 inches.
- 15-inch wheels (typical base configuration)
- Optional 16-inch wheels on certain trims or as a factory upgrade
When restoring or shopping, verify the exact wheel size for your vehicle's year and trim using the door placard or the VIN-specific build sheet, as wheel options varied by market and package.
Second generation GS300 (1998–2005)
This generation commonly used 16-inch wheels as standard, with 17-inch wheels available on higher trims or Sport packages.
- 16-inch wheels (standard on most models)
- 17-inch wheels (optional on sport or upgraded trims)
If you’re upgrading within this generation, be mindful of overall diameter and offset to avoid rubbing and to preserve the speedometer calibration.
Upgrading wheels: fitment and practical tips
Upgrading to aftermarket wheels can improve appearance or handling, but you must mind fitment parameters to stay safe and drive-legal. The GS300 typically uses a 5x114.3 bolt pattern, and proper offset and width are key to preventing rubbing and maintaining brake clearance.
- Bolt pattern: 5x114.3 mm
- Fitment range: common wheel widths span roughly 6.5–8 inches, with offsets that keep the wheel centered in the arch
- Speedometer and ABS: aim to keep the overall diameter within about +/- 3% of stock
Always verify the exact stock size for your particular car and consult a professional installer if you're unsure about offset, brake clearance, or hub bore compatibility.
Summary
For a GS300, wheel size is generation- and trim-dependent: 15-inch wheels were standard on early models, 16-inch wheels are common on mid-generation cars, and 17-inch (and sometimes 18-inch) wheels appear on sport-oriented configurations. Always confirm the exact OEM size for your car and ensure any upgrades maintain proper fitment and safety.
