What size tyres are on a Lexus?
There isn’t a single tyre size for all Lexus models. The factory size depends on the model, year, trim level, and market. In general, most current Lexus vehicles use wheels from 17 to 20 inches, with common OE tire sizes falling roughly within the 235 mm width and 50–60 series aspect-ratio range, but the exact specification must be confirmed for your vehicle. The correct size is listed on the driver’s door placard and in the owner’s manual.
How tyre sizing works on a Lexus
Tyre sizes are written in a standardized format that encodes width, profile, construction, and wheel diameter. Reading this information helps you identify the correct replacement size for your specific model and year.
Understanding these components will help you read the size printed on your tires or on the placard and pick the correct replacements for safety and performance.
What the numbers mean
- Width in millimetres: the first number (e.g., 235) is the tire’s cross-section width from sidewall to sidewall.
- Aspect ratio: the second number (e.g., 60) is the height of the sidewall as a percentage of the width.
- Construction: the letter R indicates radial construction.
- Wheel diameter: the final number (e.g., 18) is the wheel size in inches that the tire fits.
- Load index and speed rating: these appear after the size (e.g., 94V) and indicate how much weight the tire can carry and the maximum safe speed.
Knowing what these elements indicate helps you interpret the size on the door placard or tire sidewall and ensures you select a matching replacement for your Lexus.
Common OEM size ranges by Lexus line
These ranges reflect typical configurations seen on recent Lexus models. There are always exceptions by year, trim, and market, so verify your exact size on the placard or in official specs.
- SUVs and crossovers: Most Lexus SUVs use 18–20 inch wheels with tire widths commonly in the 235–275 mm range and aspect ratios often between 50 and 60, depending on trim and market. Representative examples include sizes that fall around 235/60R18 or 265/50R20 on various trims.
- Sedans and coupes: Most Lexus passenger cars use 17–19 inch wheels with widths generally in the 225–245 mm range and aspect ratios typically between 40 and 50 for sportier variants. Representative examples include sizes such as 235/45R18 or 245/40R19.
These ranges provide a general sense of what you may encounter, but always confirm the exact OE size for your vehicle before purchasing tires.
Where to find the exact size for your Lexus
To ensure you get the right tires, check the sources below. This will prevent buying tires that don’t fit or affect performance and safety.
Use these sources to confirm your exact OEM tire size for your vehicle:
- Driver-side door jamb placard, which lists the recommended tire size and inflation pressures.
- Owner’s manual or the specifications section for your model/year.
- Lexus official site or the Lexus Owner Portal, which can provide VIN-based configuration details.
- Current tires on the vehicle: read the size printed on the tire sidewall (for cross-checking your replacement choice).
By checking these sources, you ensure compatibility with your vehicle’s load, speed rating, and overall performance requirements.
How to shop safely for replacements
When replacing tires, consider factors beyond size to maintain performance, safety, and warranty. The following guidelines help ensure you choose appropriately.
- Match or exceed the load index and speed rating required for your vehicle.
- Choose the tire type suitable for your climate and driving conditions (all-season, summer, winter, or run-flat if applicable).
- Ensure the new tires have the same or compatible rolling circumference to avoid drivetrain and ABS issues if you replace tires in a partial set.
Always consult a tire professional if you’re unsure about the correct size or if you’re considering a size upgrade for aesthetics or performance. Improper sizing can affect handling, traction, and system calibrations.
Summary
There is no single tyre size for all Lexus vehicles. The correct size depends on the model, year, trim, and market. Most modern Lexus models use wheels between 17 and 20 inches, with common OE tire formats around 235 mm width and 50–60 series profiles, but exact sizes must be verified on the door placard or owner’s manual. Use the placard, the manual, and the VIN-based specs from official Lexus sources to identify the exact size, and consider load index, speed rating, and climate when selecting replacements for safe, optimal performance.
