The 2011 Acura TL sits at an interesting point in the sport-sedan market, blending Acura’s upscale touring character with a more assertive stance than many earlier front-drive luxury sedans. For buyers today, tire selection matters because this exact model spans three primary radial sizes: 245/50R17, 245/45R18, and 245/40R19, with fitment changing by sub-model and wheel package. That makes the first decision less about brand loyalty and more about identifying the wheel diameter and configuration on the car. From there, the choice centers on comparing blackwall performance-oriented radial options that suit either a factory-style setup or a modified street-driven TL.
Which Tire Size Is Right for The 2011 Acura TL
The 2011 Acura TL uses three primary tire sizes, and the right one depends on the exact sub-model and wheel diameter on the car. Base and SH-AWD fitment overlap in one 18-inch size, but the 17-inch and 19-inch sizes are configuration-specific, so the first step is confirming both the sub-model and the actual wheels currently installed before selecting a tire.
A 245/45R18 tire is a metric radial size with a 245-millimeter nominal section width, a 45-series aspect ratio, and an 18-inch rim diameter. On the 2011 Acura TL, this is one of the shared fitments across more than one sub-model, making it a common choice when the car is running 18-inch wheels. Available options center on blackwall radial performance tires from BFGoodrich and Nitto, with series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. This size is worth evaluating carefully if your TL already wears 18-inch wheels and you want to compare touring-versus-performance character within the same basic fitment.
A 245/50R17 tire uses the same 245-millimeter nominal width but pairs it with a 50-series profile on a 17-inch rim. For the 2011 Acura TL, this size applies to the Base model rather than the full range, so it should not be treated as universal across all TL configurations. Its dimensions keep it in the same general fitment family as the other TL sizes while matching a different wheel diameter. This is the size to pursue when the car still uses its 17-inch wheel setup and the goal is to preserve that configuration rather than move to a different rim size.
A 245/40R19 tire is a metric radial with a 245-millimeter nominal width, a lower 40-series profile, and a 19-inch rim diameter. On the 2011 Acura TL, this size is tied to a specific sub-model application, so it should be matched to the correct wheel package rather than selected by appearance alone. Product choices in this size include blackwall BFGoodrich options in g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. This size makes sense when the car is already equipped with 19-inch wheels and you want to stay with the intended low-profile fitment rather than backtrack to a smaller rim.
Sub-model fitment matters on the 2011 Acura TL because the covered configurations do not all use the same tire size. The Base and SH-AWD versions share one 18-inch fitment, but each also has another size tied to a different wheel diameter, so exact configuration and current wheels should be confirmed first.

2011 Acura TL Base
The 2011 Acura TL Base uses two radial tire sizes, with fitment centered around either a 17-inch or 18-inch wheel setup. That means tire selection starts with confirming which wheels are on the car now, then comparing the available replacement options within the matching size.
The 2011 Acura TL SH-AWD uses two radial tire sizes, with applications tied to either 18-inch or 19-inch wheels. Choosing correctly means verifying the actual wheel diameter first, then selecting among the available low-profile blackwall radial options that match that setup.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Owners shopping tires for a 2011 Acura TL usually need to sort out size by sub-model and wheel diameter first. The questions below focus on fitment, radial tire choices, product differences, and the wheel and suspension checks worth making before road use.
Tire Size & Fitment
What tire size fits a 2011 Acura TL?
The 2011 Acura TL uses three primary radial tire sizes: 245/50R17, 245/45R18, and 245/40R19. The correct size depends on the exact sub-model and the wheel diameter on the car, since Base and SH-AWD applications do not use the same full set of tire sizes.
The practical first step is to confirm whether the car is a Base or SH-AWD model, then verify whether it currently wears 17-inch, 18-inch, or 19-inch wheels. A TL may no longer have its original wheel setup, so reading the sidewall and checking the wheel diameter helps prevent choosing the right size for the wrong configuration.
What size rim does a 2011 Acura TL use?
A 2011 Acura TL can use 17-inch, 18-inch, or 19-inch rims, depending on sub-model and wheel package. The 245/50R17 fits a 17-inch rim, the 245/45R18 fits an 18-inch rim, and the 245/40R19 fits a 19-inch rim.
Rim diameter is the most important fitment checkpoint because the tire size must match the wheel exactly. After diameter is confirmed, wheel width still matters, especially on the 18-inch and 19-inch performance sizes where product options have defined rim-width ranges. Checking both dimensions is especially important if the TL has aftermarket wheels.
Do all 2011 Acura TL sub-models use the same tire size?
No. The 2011 Acura TL Base and 2011 Acura TL SH-AWD share the 245/45R18 size, but they do not share every fitment. The Base also uses 245/50R17, while the SH-AWD also uses 245/40R19.
That overlap can cause confusion because an 18-inch TL tire may be correct for more than one configuration, while the 17-inch and 19-inch sizes are more specific. Sub-model identification and wheel confirmation should happen together, especially on used cars that may have had wheels changed for appearance, ride, or seasonal use.
Choosing the Right Tire
What should I consider when choosing a 245/45R18 tire for a 2011 Acura TL?
Start with the correct size, then compare the tire’s intended character, construction details, and wheel compatibility. In 245/45R18, the 2011 Acura TL has blackwall radial options from BFGoodrich and Nitto, with series including g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2.
The useful comparison points are rim-width range, load figures where stated, and whether the tire suits the way the car is driven. Some owners want a more all-season-oriented performance feel, while others are focused on a more aggressive street presentation. Matching those priorities to the actual 18-inch wheel setup is more important than choosing by brand name alone.
What sidewall styles are available for 2011 Acura TL tires?
The currently covered 2011 Acura TL tire options use blackwall sidewalls. That applies to the available 18-inch and 19-inch products, so the visible difference between choices comes more from tire series and overall tread character than from whitewall, stripe, or raised-letter styling.
That keeps the selection straightforward for owners who want a clean modern sport-sedan look. Since sidewall treatment is not the main variable here, attention shifts to choosing the correct size, confirming wheel width, and deciding whether the tire should support a stock-style road car, a more aggressive street build, or a replacement for modified wheels.
What brands offer tires for the 2011 Acura TL?
BFGoodrich and Nitto both offer tire options for the 2011 Acura TL within the currently available fitments. BFGoodrich appears across several g-Force series, while Nitto is represented in 245/45R18 with the NT555 G2.
The brand choice matters less than making sure the tire matches the car’s actual wheel diameter and intended use. Comparing series within the correct size often tells the buyer more than comparing brand names by themselves, especially when the available assortment is centered on performance-oriented blackwall radial tires rather than broad touring or vintage-style categories.
Restoration & Appearance
Which tire should I choose for a period-style 2011 Acura TL?
A period-style 2011 Acura TL usually starts with staying in the original fitment family already on the car, whether that means 245/50R17, 245/45R18, or 245/40R19. Because this is a modern sport-luxury sedan, the visual character comes more from preserving the right wheel-and-sidewall proportion than from vintage sidewall treatments.
A clean blackwall radial generally suits the TL’s original-era appearance better than trying to force a style associated with older collector cars. The best approach is to confirm the sub-model and wheel diameter, then choose a tire that keeps the car’s stance and profile in line with its 2011 design rather than chasing an unrelated appearance theme.
Does correct tire fitment matter for a 2011 Acura TL restoration?
Yes. Correct tire fitment matters on a 2011 Acura TL because this model used more than one size, and the visual effect changes noticeably between the 17-inch, 18-inch, and 19-inch setups. Using the wrong diameter or profile can alter the car’s stance and move it away from a proper restoration-oriented presentation.
Restoration-minded buyers should verify the exact sub-model, wheel size, and any previous changes before choosing tires. When originality matters closely, period photos, original sales literature, and marque-specific references can help confirm how a particular TL was equipped. That is especially useful on cars that have passed through multiple owners or received aftermarket wheel upgrades.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2011 Acura TL?
Yes. A 2011 Acura TL can be sensitive to wheel and tire changes because its factory fitments already span 17-inch, 18-inch, and 19-inch diameters. Aftermarket wheels, altered offsets, suspension lowering, or changes in wheel width can all affect whether the intended tire size clears the fenders and suspension properly.
A modified TL should be measured rather than assumed to match stock fitment. Wheel diameter is only the first checkpoint; width, offset, and available clearance around the strut, inner fender, and steering arc matter too. Those checks become especially important when moving between the lower-profile 19-inch setup and a different wheel package.
What should I inspect before driving a 2011 Acura TL on new tires?
Before road use, inspect wheel condition, confirm the tire size matches the wheel diameter, and make sure inflation is set appropriately for the tire and vehicle setup. It is also smart to check for uneven suspension wear, alignment issues, and any signs that the old tires were rubbing or wearing abnormally.
A short test drive should be used to listen for contact noise and feel for vibration, pull, or steering irregularity. On a 2011 Acura TL with replacement or aftermarket wheels, rechecking lug torque and verifying clearances after the first few miles is a sensible habit. Those simple checks help catch setup problems before they become expensive or unsafe.
What should I check before a longer drive in a 2011 Acura TL?
Before a longer drive, make sure the 2011 Acura TL’s tires are evenly inflated, free of cuts or bulges, and wearing consistently across the tread. Wheel condition, valve stems, and visible sidewall condition all deserve attention, especially if the car has been sitting or is used only occasionally.
Longer highway use puts more emphasis on stability and heat management, so any vibration, slow air loss, or odd wear pattern should be addressed first. It also helps to confirm that the car’s alignment and suspension are in good order, since modern low-profile TL fitments can make irregular wear and ride issues more noticeable on extended trips.
