What tires come standard on an Acura TLX?
There isn’t a single universal tire size for every TLX. The standard tires depend on the model year and trim. In general, the current TLX lineup uses either 18-inch wheels on base versions or 19-inch wheels on higher trims, with the exact tire size specified on the door placard.
Overview by TLX generation
Understanding the TLX’s tire setup starts with identifying the generation and trim. Acura’s modern TLX generations offer two wheel-size families, and the factory tire size is matched to those wheels. The most recent fourth‑generation TLX (introduced for 2021 and refreshed in 2023) is the most common reference point for owners today.
Fourth-generation TLX (2021–present)
The latest TLX models align their tires with wheel size and trim level. In broad terms, most higher-trim configurations ride on 19-inch wheels with tires sized to fit that package, while base configurations use 18-inch wheels with correspondingly sized tires. The exact tire size and pattern can vary by year, market, and factory options, so the official specification is the best source for precision.
To summarize how this typically breaks down across trims in the latest generation:
- Base TLX — 18-inch wheels with factory tires matched to that wheel package.
- Technology / A-Spec / Advance — 19-inch wheels with factory tires matched to that wheel package.
- Type S — 19-inch wheels with higher-performance factory tires suited to the sport-focused setup.
In short, the TLX’s standard tire setup is not a single size across all trims; it depends on wheel size, year, and market. Always verify the exact size on the door jamb placard or in the owner’s manual for your specific vehicle.
How to confirm the exact tire size for your TLX
To ensure you’re looking at the correct specification for your car, follow these steps. They’ll give you the precise standard tire size for your exact TLX configuration.
- Check the driver’s door jamb placard, which lists the recommended tire size for the current wheel package.
- Consult the owner’s manual, which provides tire sizes for each trim and wheel option.
- Examine the tire sidewall on the vehicle to read the size imprinted on the tire that is currently installed.
- If you’re unsure or your vehicle has mixed options, contact an Acura dealer or use Acura’s official website or support line for the VIN-specific specification.
Having the exact size confirmed will help you source the correct replacement tires and maintain the intended performance and warranty coverage.
Additional considerations when replacing tires
When selecting replacements, consider the following:
- Tire type: Most TLX trims use all-season tires from the factory; performance variants may use higher-grip all-season or summer tires depending on market and options.
- Speed rating and load index: Match or exceed the original specifications printed on the door placard and sidewall.
- Warranty and performance notes: Using a different size or tire type can affect warranty coverage and ride characteristics; consult your dealer if in doubt.
In practice, the standard tire setup is a function of wheel size and trim rather than a single universal spec for all TLX models. Verified by the placard and manual, your TLX’s tires are chosen to align with its performance and comfort targets for that particular configuration.
Summary
There isn’t one universal tire size for the Acura TLX. The standard tires depend on model year, trim, and wheel size, with 18-inch wheels typically paired with one size of tires on base configurations and 19-inch wheels paired with another size on higher trims. To know the exact size for your car, check the door placard, consult the owner’s manual, or contact a dealer for VIN-specific specifications. This ensures you source the correct tires and maintain intended performance and warranty protections.

Why is Acura discontinuing TLX?
Acura is discontinuing the TLX primarily due to declining sales and the broader market shift away from sedans towards SUVs and crossovers. In recent years, TLX sales have dropped significantly, and Acura is focusing on higher-demand vehicles, including new electric SUVs like the upcoming RSX, which will replace the TLX on the production line.
- Declining sales: The TLX's sales have been in a steady decline since 2015, with sales figures for 2024 showing only a fraction of its previous peak. For example, in the first half of 2025, only 3,634 units were sold.
- Market shift to SUVs: The automotive industry is seeing a major shift in consumer preference from sedans to SUVs and crossovers. Acura's decision reflects this trend, as they are reallocating resources to their more popular SUV models.
- Focus on electric vehicles: Acura is also pivoting towards electrification, and the production capacity at the TLX's Marysville, Ohio, plant will be used for a new electric SUV, the RSX.
- Brand strategy: The discontinuation is part of Acura's larger strategy to streamline its lineup and focus on future growth areas, such as electric vehicles and its SUV offerings.
