The 2017 Acura RLX sits in a small corner of the luxury sedan market, blending Acura’s flagship comfort and technology with a more understated personality than many European rivals. Whether in Base form or Sport Hybrid SH-AWD trim, it is a modern full-size sedan that depends on precise tire fitment to preserve ride quality, steering response, and overall road manners. This RLX uses a 245/40R19 radial tire, so the decision is less about multiple factory sizes and more about choosing the right radial within that format. Available options center on BFGoodrich blackwall performance-oriented series, making wheel compatibility, intended driving use, and tire character the key points to verify.
Which Tire Size Is Right for The 2017 Acura RLX
The 2017 Acura RLX uses one primary tire size: 245/40R19 on a 19-inch rim. That fitment is shared by both the Base and Sport Hybrid SH-AWD sub-models, so the main decision is choosing the right radial tire within the correct size, rim-width range, and product style rather than sorting through multiple factory sizes.
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 2017 Acura RLX, this is a modern low-profile radial fitment that supports the sedan’s balance of handling precision, ride control, and contemporary wheel proportions. Available choices in this size center on BFGoodrich blackwall tires across g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A series. Selecting within 245/40R19 comes down to matching the tire to your actual wheel width, driving use, and the kind of response you want from the car.
Tire fitment is straightforward across the covered 2017 Acura RLX sub-models, with both using the same primary size. Checking the exact sub-model still matters when confirming the vehicle’s current wheel setup, especially if the car has been changed from stock.

2017 Acura RLX Base
The 2017 Acura RLX Base uses the same 245/40R19 radial tire size as the other covered RLX configuration. Tire selection is therefore centered on choosing the right product within that size, with attention to wheel width, driving character, and overall condition of the car’s suspension and alignment.
The 2017 Acura RLX Sport Hybrid SH-AWD also uses 245/40R19 radial tires on a 19-inch rim. That keeps sizing simple, but it still makes sense to confirm the actual wheels on the car and compare tire specifications carefully before choosing among the available radial options.
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.

Tire Size & Fitment
What tire size fits a 2017 Acura RLX?
The 2017 Acura RLX uses a 245/40R19 radial tire size. That fitment applies to both the Base model and the Sport Hybrid SH-AWD, so the primary factory-style sizing question is straightforward across the covered RLX lineup.
The important next step is confirming that the car still has its correct 19-inch wheel setup and that the wheel width matches the tire’s approved range. If the car has aftermarket wheels or prior tire changes, check size markings on the current tires and wheels before selecting a replacement.
What size rim does a 2017 Acura RLX use?
The 2017 Acura RLX uses a 19-inch rim with its 245/40R19 tire fitment. The available tire options in this size are built for that rim diameter, so staying with the correct wheel diameter is essential when replacing tires.
Rim diameter is only part of the fitment picture, since wheel width also affects which tires are suitable. Several available 245/40R19 options are intended for wheel widths from 8.0 to 9.5 inches, making it smart to verify the actual wheel dimensions before mounting a new set.
Do all 2017 Acura RLX sub-models use the same tire size?
Yes. Both the 2017 Acura RLX Base and the 2017 Acura RLX Sport Hybrid SH-AWD use the same 245/40R19 radial tire size. That consistency simplifies replacement because there is no split fitment among the covered sub-models.
Even with shared sizing, it is still worth checking the wheels actually installed on the car. A previous owner may have changed wheels or tire brands, and verifying rim diameter, wheel width, and overall tire condition helps prevent buying a correct-size tire for an incorrect current setup.
Choosing the Right Tire
What should I consider when choosing a 245/40R19 tire for a 2017 Acura RLX?
Start with the correct 245/40R19 size, radial construction, and a tire that matches a 19-inch wheel. For the 2017 Acura RLX, the next points are wheel-width compatibility, intended use, and whether you want a more performance-oriented or more all-season-focused tire character within the available choices.
Looking at tire series can help narrow the decision without changing size. It also helps to compare load information where stated, plus the car’s present alignment and suspension condition, since a premium sedan like the RLX responds noticeably to tire choice and setup quality.
What sidewall styles are available for 2017 Acura RLX tires?
The available 245/40R19 tires for the 2017 Acura RLX use a blackwall sidewall style. That gives the car a clean modern appearance that suits the RLX’s understated luxury-sedan design and keeps the visual focus on the wheel rather than on sidewall ornamentation.
Since sidewall treatment is not the main point of variation here, the more meaningful comparison is between tire series and specifications within the blackwall format. Buyers should focus on the right size, approved wheel width, and the driving feel they want from the car once mounted.
What tire series are available for the 2017 Acura RLX?
The 2017 Acura RLX has 245/40R19 options in BFGoodrich g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A series. All are radial blackwall tires in the correct size, but they give the buyer distinct series choices within the same fitment.
Choosing between series is a matter of intended use and overall setup rather than changing the vehicle’s base tire size. Comparing wheel-width range, any stated load specification, and how the car is driven will usually be more useful than focusing on series names alone.
Restoration & Appearance
Which tire should I choose for a period-style 2017 Acura RLX?
A period-style approach on a 2017 Acura RLX still points to the correct modern 245/40R19 radial fitment. Since the RLX is a contemporary luxury sedan rather than a vintage restoration subject, the visual goal is usually a clean, proper modern presentation instead of a classic-style sidewall treatment.
Blackwall tires suit that look well, and the main differences come from tire series rather than appearance details like whitewalls or stripes. Keeping the correct size and wheel relationship matters more than chasing a stylistic change that could pull the car away from its intended character.
Does correct tire fitment matter for a 2017 Acura RLX restoration or preservation-minded owner?
Yes. Even on a newer collector-interest sedan like the 2017 Acura RLX, correct tire fitment matters because size, profile, and wheel relationship strongly influence how the car sits, steers, and presents visually. The proper 245/40R19 size preserves that overall balance.
Preservation-minded owners should pay attention to matching size, radial construction, and wheel width before experimenting with alternatives. A car kept close to its intended configuration generally benefits from a tire that maintains its original stance and modern luxury-sedan proportions rather than altering them.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Acura RLX?
Yes. A 2017 Acura RLX may use the correct 245/40R19 tire size from the factory-style setup, but aftermarket wheels, changes in wheel width, suspension alterations, or body-height changes can all affect whether a replacement tire remains suitable for the car.
Checking the current wheel diameter and width is the first step, followed by a look at clearance around the fenders, suspension, and steering range. Even when the tire size stays the same, an altered wheel or chassis setup can change how well that tire works on the vehicle.
What should I inspect before driving a 2017 Acura RLX on new tires?
Before regular road use, inspect wheel condition, lug hardware, tire pressure, and the basic condition of the suspension and alignment. On a 2017 Acura RLX, it also makes sense to confirm that the new tires are the correct 245/40R19 size and are mounted on the proper 19-inch wheels.
A quick visual check for rubbing, uneven clearance, or signs of prior tire wear can prevent problems early. It is also wise to monitor the first several drives for vibration, pull, or unusual noise, since those symptoms can point to balance, alignment, or wheel-related issues.
How often should tires on a 2017 Acura RLX be inspected?
Tires on a 2017 Acura RLX should be inspected regularly, not just when tread looks low. Routine checks should include air pressure, visible tread wear, cuts, punctures, bulges, and any cracking or damage along the sidewall area.
Luxury sedans can mask tire problems with a quiet ride, so visual inspection matters as much as how the car feels on the road. It helps to check the tires before longer drives and any time the car develops vibration, pull, or a sudden change in handling response.
