What size tires are on a Lexus GS 300?
There isn't one universal tire size for all Lexus GS 300s—the size depends on the model year, market, and wheel option used by the factory. To know your exact size, check the door jamb placard or the owner's manual, or inspect the tires themselves for the "TIRE SIZE" markings.
Why tire sizes vary across the GS 300 lineup
The GS 300 has appeared in several generations and regional markets. Each generation offered different wheel options and trim levels, which means the stock tire size could shift when the car was updated or when new wheels were chosen at the factory. Additionally, some owners replace wheels with aftermarket sizes that change the overall tire size. For these reasons, your car's exact size could be any of several standard sizes used in the lineup.
Common tire size ranges by wheel diameter
The following sizes are representative stock configurations used on various GS 300 models over the years. Use this as a reference only; confirm the exact size on your vehicle.
- 15–16 inch wheels: commonly around 205/65R15 or 205/60R16, depending on the model year and trim.
- 17 inch wheels: commonly around 235/45R17 or 225/50R17.
- 18–inch wheels: commonly around 235/45R18 or 245/40R18, depending on the setup.
- 19 inch wheels (rare but possible with some sport/prestige packages): commonly around 235/40R19 or 255/35R19.
Again, these are representative ranges. The exact specification for your vehicle can only be confirmed from the placard or the original order sheet.
How to determine your exact tire size
- Look inside the driver’s door jamb for a tire size label (the placard). It lists the recommended tire sizes for the vehicle as it left the factory.
- Check one of the current tires’ sidewalls for the "TIRE SIZE" marking (for example, P225/50R17). This shows the tire width, aspect ratio, and wheel diameter you are currently using.
- Consult the owner's manual or a dealership with your VIN to retrieve the original equipment size if the placard is missing or if you’re verifying a replacement match.
- When replacing, consider the overall tire diameter to maintain speedometer accuracy and vehicle dynamics. If you plan to switch sizes, consult a tire/wheel professional to ensure compatibility with suspension and ABS systems.
Knowing the exact size is essential for maintaining handling, ride comfort, and speedometer accuracy. If you want, provide your GS 300’s year, market, and whether you have 15", 16", 17", or 18" wheels, and I can give a tighter, more precise range for that specific configuration.
What about aftermarket tires?
Aftermarket options may use different sizes that preserve overall diameter or adjust for performance. When changing to non-stock sizes, you may need to adjust the wheel size, offset, and potentially use a speedometer calibration or vehicle stability controls. Always verify fitment against your vehicle’s suspension and brake components.
Quick reference by era
Late 1990s GS 300 models
Most early GS 300 sedans used 15–16 inch wheels with sizes in the 205/60R16 style, though some markets offered 15-inch spares and different configurations. Exact size depended on market and trim.
Mid-2000s GS 300 (S190 era)
During the mid-2000s, many GS 300 cars moved to 17-inch wheels, with tire sizes around 235/45R17 or 225/50R17 as common factory configurations. Some sport variants used wider tires.
Late-2000s to early-2010s GS 300
As wheel options expanded, 18-inch setups became more common, with sizes like 235/45R18 or 245/40R18 under various trims or with optional wheels. Always verify for your car.
Summary: Tire sizes for the Lexus GS 300 vary by generation and trim. To be sure, check the placard in the door jamb, inspect the current tires for the size marking, or refer to the vehicle’s VIN-based original equipment information. If you share your model year and market, I can provide a precise size for that configuration.
Summary
In short, there is no single “GS 300 tire size.” Use your exact year and market to identify the correct stock size, and consider the wheel diameter when planning replacements. Confirm with the placard or manual for accuracy, and consult a tire professional if you’re adjusting sizes for performance or fitment reasons.
