2012 Acura TL Tires

The 2012 Acura TL uses three primary tire sizes: 245/50R17, 245/45R18, and 245/40R19. All are radial fitments, but they do not apply across every configuration in the same way. The Base model uses 245/50R17 or 245/45R18, while the SH-AWD uses 245/45R18 or 245/40R19.

The practical first step is to confirm the exact sub-model and the wheel diameter already on the car. A TL with 17-inch wheels needs a different tire than one on 19-inch wheels, even though the overall dimensions stay quite close. If the car has aftermarket wheels, check the actual rim size before selecting a replacement tire.

A 2012 Acura TL can use 17-inch, 18-inch, or 19-inch rims depending on the sub-model and wheel package. The 245/50R17 tire fits a 17-inch rim, the 245/45R18 fits an 18-inch rim, and the 245/40R19 fits a 19-inch rim. Tire size and wheel diameter must match exactly.

That means rim diameter should be verified before anything else, especially on a car that may have had wheels changed over time. Reading the current tire sidewall is helpful, but the wheel itself should still be checked. Matching the correct tire to the actual rim avoids unnecessary confusion between Base and SH-AWD fitments.

No. The 2012 Acura TL Base and 2012 Acura TL SH-AWD do share 245/45R18 as one possible fitment, but they do not use the same complete size range. The Base model also uses 245/50R17, while the SH-AWD also uses 245/40R19. Tire choice depends on the specific version and wheel package.

That overlap is why it helps to identify both the sub-model and the wheel diameter before ordering replacement tires. A quick look at the existing tire size often answers the question, but a previous owner could have changed wheels. Staying with the current correct wheel-and-tire combination is usually the cleanest path for straightforward fitment.

Start with the fact that 245/45R18 is an 18-inch radial fitment used on both covered 2012 Acura TL sub-models. Once that size is confirmed on the car, the main differences come from brand, tire series, rim-width specification, load details where stated, and the tire’s intended character within the available product range.

BFGoodrich and Nitto both appear in this size, with blackwall options across several series including g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. Comparing those details makes more sense than treating every 245/45R18 tire as the same. The right choice depends on the existing wheel setup and the kind of driving the car actually sees.

The available 2012 Acura TL fitments shown here include BFGoodrich and Nitto. BFGoodrich appears in both 18-inch and 19-inch applications, while Nitto appears in the 245/45R18 size. Those brand choices are tied to specific tire sizes, so the wheel diameter on the car still determines which products can be compared.

Brand should be considered alongside the exact size, tire series, and rim-width compatibility rather than by itself. On this TL, not every brand appears in every fitment, so the strongest comparison starts after the size is confirmed. That approach keeps the focus on the tire that matches the car’s existing wheel package first.

Available tire series for the 2012 Acura TL include BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2. These series appear in the supported 18-inch and 19-inch fitments and give buyers more than one modern radial option within the correct size range.

The useful comparison is not just the series name, but where that series is offered. Some series appear in both 245/45R18 and 245/40R19, while others are limited to a single size. Once the correct wheel diameter is confirmed, series differences help narrow the choice without drifting away from the TL’s proper fitment.

Yes. Even though a 2012 Acura TL is much newer than a traditional collector car, correct tire fitment still matters for maintaining the car’s intended stance, wheel relationship, and overall presentation. Using the proper 17-inch, 18-inch, or 19-inch fitment for the exact sub-model keeps the appearance consistent with the wheel package the car was built around.

A restoration-minded owner should avoid assuming that similar overall tire dimensions make every size interchangeable. The safest approach is to confirm the sub-model, inspect the current wheels, and match the tire size to that setup. If absolute originality matters, compare the car against Acura-specific reference material and the vehicle’s own equipment history.

On the 2012 Acura TL, appearance differences come less from bias-ply versus radial construction and more from using the correct modern radial size on the proper wheel diameter. All primary fitments here are radial, so the visual effect comes from whether the car sits on the right 17-inch, 18-inch, or 19-inch package for its configuration.

Sidewall treatment is straightforward in the available choices because the products shown are blackwall tires. That keeps the visual decision centered on fitment and series selection rather than period-style whitewalls or stripes. A restored or carefully kept TL usually looks most coherent when tire size, wheel diameter, and sub-model configuration all stay aligned.

Yes. Wheel changes, suspension alterations, lowering, and body modifications can all affect tire fitment on a 2012 Acura TL, even when the tire size looks close to stock. The car’s original fitments already span 17-inch, 18-inch, and 19-inch wheels, so a modified setup can change the clearance picture quickly.

A TL with aftermarket wheels should be checked for actual rim diameter and width before replacement tires are chosen. Clearance at the fender, strut, and steering range also matters, especially near full lock or full suspension travel. Matching the original size printed on the door jamb is less useful if the wheel-and-suspension package has been changed.

Before driving a 2012 Acura TL on new tires, inspect the wheels for damage, confirm that the tire size matches the rim diameter, and verify proper inflation. It also helps to check for uneven wear patterns on the old tires, because those can point to alignment or suspension issues that should be addressed before putting mileage on the replacement set.

A short road test should include listening for rubbing, vibration, or pulling that was not present before. Lug torque, valve condition, and visible clearance around the inner wheel well deserve a second look after the first drive. On a car that has seen wheel changes, that follow-up inspection is especially important.

Tires on a 2012 Acura TL should be inspected regularly, not just when replacement time arrives. A quick visual check for cuts, bulges, cracking, punctures, and uneven tread wear is worthwhile every month, and air pressure should be monitored on the same schedule. A more careful inspection makes sense before longer trips or seasonal driving changes.

Cars that are driven less often still need attention because age and storage conditions can affect tire condition even when tread looks acceptable. Pressure loss can also go unnoticed on a garage-kept vehicle. Looking at the tires as part of routine maintenance helps catch problems early and keeps the TL’s handling consistent with the wheel-and-tire package already in place.
