The 2016 Acura RLX sits in the modern full-size luxury sedan class, blending Acura comfort, technology, and understated performance in a way that appeals to owners who still want a sharp-driving flagship. Whether kept as a refined daily driver or maintained as a well-preserved late-model Acura, tire fitment matters because the car rides on a low-profile 245/40R19 radial setup. That means the decision is less about sorting through multiple factory sizes and more about choosing the right 19-inch radial within that fitment. Blackwall performance-oriented options are available across several BFGoodrich g-Force series, so the focus should stay on correct size, wheel compatibility, and the type of road use the car sees.
Which Tire Size Is Right for The 2016 Acura RLX
The 2016 Acura RLX uses one primary tire size: 245/40R19, a radial tire for a 19-inch rim. Both the Base and Sport Hybrid SH-AWD share that same fitment, so the main choice is selecting the right tire within the size rather than sorting through multiple factory sizes. From there, the important comparisons are tire series, load-related specifications, and confirming wheel width and overall setup before installation.
A 245/40R19 tire uses a 245-millimeter section width, a 40-series aspect ratio, radial construction, and a 19-inch rim diameter. On the 2016 Acura RLX, this low-profile radial fitment supports the car's modern luxury-sedan stance and keeps the tire choice centered on current road manners rather than vintage sizing conventions. Available options in this size come from BFGoodrich in the g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A series, all in Blackwall form. This is the size to evaluate when the goal is staying with the RLX's original fitment format while comparing tire character, wheel-width compatibility, and intended use.
Tire fitment is straightforward across the covered 2016 Acura RLX sub-models because both use the same primary tire size. Even so, checking the exact sub-model remains worthwhile when confirming the wheel and tire setup on a car that may have been changed over time.

2016 Acura RLX Base
The 2016 Acura RLX Base uses the same 245/40R19 radial fitment found across the core model range. Tire selection therefore comes down to choosing the right 19-inch radial within that size and confirming the car still carries the proper wheel setup.
The 2016 Acura RLX Sport Hybrid SH-AWD also uses a 245/40R19 radial tire. Since the fitment stays the same, the key decision is comparing available tire series and specifications while making sure the current wheels match the intended tire's rim-width requirements.
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.

Common 2016 Acura RLX tire questions usually center on the 245/40R19 size, 19-inch wheel fitment, differences between available BFGoodrich radial choices, and what to inspect before putting a low-profile luxury sedan back into regular road use.
Tire Size & Fitment
What tire size fits a 2016 Acura RLX?
The 2016 Acura RLX uses a 245/40R19 tire size. That fitment applies as a radial tire on a 19-inch rim, and it is used on both the RLX Base and the RLX Sport Hybrid SH-AWD covered here.
Because the RLX uses one primary size across both sub-models, the next step is choosing the right tire within that fitment rather than deciding between multiple factory sizes. It is still smart to confirm that the car has its correct 19-inch wheels, especially if it has had aftermarket wheel changes or prior tire substitutions.
What size rim does a 2016 Acura RLX use?
The 2016 Acura RLX uses a 19-inch rim diameter with its 245/40R19 tire size. Product options in this fitment are built for that 19-inch wheel diameter, so matching the tire to the wheel diameter is the first non-negotiable step.
Wheel diameter alone is not the whole fitment picture. Many 245/40R19 tires in this application also carry rim-width guidance, so the actual wheel width should be checked before choosing among available tires. That matters even more on a low-profile sedan tire, where wheel mismatch can affect appearance, mounting suitability, and clearance.
Do all 2016 Acura RLX sub-models use the same tire size?
Yes. Both the 2016 Acura RLX Base and the 2016 Acura RLX Sport Hybrid SH-AWD use the same 245/40R19 radial tire size. There is no split in primary tire sizing between those two covered sub-models.
That consistency makes shopping simpler, but it does not eliminate the need to inspect the actual car. A used RLX may already have replacement wheels or a different tire installed, so it is worth checking the current wheel diameter and width before selecting a new tire. Staying with the proper size helps preserve the intended fitment balance.
Choosing the Right Tire
What should I consider when choosing a 245/40R19 tire for a 2016 Acura RLX?
Start with the correct 245/40R19 size and confirm that the tire is intended for a 19-inch wheel. From there, compare the available radial tire series, the tire's stated rim-width range, and load-related specifications where they are given, since those factors shape which option best suits the car's setup.
A 2016 Acura RLX is a modern luxury sedan with a low-profile tire fitment, so the details matter. Some owners may prioritize an all-season style of use, while others may focus on a more performance-oriented feel. Matching the tire to the wheel, the car's current condition, and the way it will actually be driven leads to a better decision than choosing by name alone.
What sidewall styles are available for 2016 Acura RLX tires?
The available 245/40R19 tires for the 2016 Acura RLX shown here use a Blackwall sidewall style. That keeps the appearance clean and contemporary, which suits the RLX's modern luxury-sedan presentation.
Since there is not a mix of whitewall, redline, or other vintage-style treatments in this fitment, the visual choice is really about tire series rather than sidewall decoration. Owners who are comparing options should concentrate on the tire's construction, rim-width compatibility, and the type of driving the car sees instead of expecting broad appearance variation within this size.
What tire series are available for the 2016 Acura RLX?
The 2016 Acura RLX has 245/40R19 options in several BFGoodrich g-Force series, including g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A. All are radial Blackwall tires built around the same basic size and wheel diameter.
Those series names matter because they help separate the choices within a single fitment. When comparing them, pay attention to the tire's intended character, the wheel-width range, and any load-related details that are included. That approach is more useful than assuming every 245/40R19 tire will feel or suit the RLX in exactly the same way.
Restoration & Appearance
Does correct tire fitment matter for a 2016 Acura RLX restoration?
Yes, correct tire fitment still matters on a 2016 Acura RLX, even though it is a modern vehicle rather than a vintage restoration subject. Keeping the proper 245/40R19 size on a 19-inch wheel helps preserve the car's intended stance, proportion, and overall presentation.
Appearance on a late-model Acura is usually more about maintaining the correct modern look than recreating a period sidewall treatment. A car that has been altered with different wheels or an off-size tire can lose that balance quickly. Verifying the wheel setup and staying close to the proper fitment is the cleanest path for an owner who values original character.
How does tire choice affect the appearance of a 2016 Acura RLX?
Tire choice affects the 2016 Acura RLX mostly through size fidelity, sidewall profile, and overall presentation. In this fitment, the available options are Blackwall 245/40R19 radials, so the visual character remains modern and understated rather than overtly styled.
The biggest appearance change usually comes from using the wrong size or mounting a tire on an unsuitable wheel width, which can alter the way the tire sits on the rim. Keeping the proper low-profile fitment helps the RLX retain its intended look, while the final choice among tire series becomes a subtler decision than on older collector vehicles.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2016 Acura RLX?
Yes, modifications can affect tire fitment on a 2016 Acura RLX even when the intended tire size remains 245/40R19. Aftermarket wheels, changes in wheel width, altered offsets, suspension modifications, or ride-height changes can all influence how that tire sits and clears the body and chassis.
A low-profile 19-inch fitment leaves less room for guesswork than taller sidewall applications. Any RLX that has been lowered, fitted with non-original wheels, or repaired with different components should be checked for wheel dimensions and clearance before a new tire is chosen. That inspection helps avoid rubbing, improper wheel match, or an awkward overall stance.
What should I inspect before driving a 2016 Acura RLX on new tires?
Before driving a 2016 Acura RLX on new tires, inspect the wheel condition, confirm the correct 19-inch wheel diameter and proper width, and make sure the tires are inflated appropriately for their installation. It is also smart to check for suspension wear, alignment issues, and any signs that the previous tires contacted fenders or inner components.
A fresh set of tires cannot compensate for underlying chassis problems. Looking over the current setup helps the new 245/40R19 tires wear more evenly and behave as expected on the road. Extra attention is worthwhile on any RLX that has sat for long periods, since storage, age, and unnoticed damage can affect both the tires being removed and the vehicle receiving the replacements.
How often should tires on a 2016 Acura RLX be inspected?
Tires on a 2016 Acura RLX should be inspected regularly, not just when tread looks low. A routine check for uneven wear, cuts, bulges, cracking, embedded debris, and air loss is especially important with a 245/40R19 low-profile tire, where sidewall and shoulder condition deserve close attention.
Inspection becomes even more important if the car is driven infrequently or stored for long stretches. A sedan that sits can still develop tire issues from age, pressure loss, or environmental exposure. Building tire checks into normal maintenance and before longer drives helps catch problems early and protects the wheel-and-tire fitment the RLX depends on.
