The 2016 Lexus RC300 sits in the modern luxury sport coupe space, blending sharp styling with the kind of chassis tuning that makes tire choice matter as much as appearance. Buyers looking at this exact RC300 are usually balancing road manners, wheel fitment, and the visual stance that suits the car. This model uses radial tires in two primary sizes, 235/45R18 and 235/40R19, with fitment depending on the exact sub-model and wheel setup. Available choices stay firmly in a modern blackwall performance-oriented look. The key is confirming whether the car is a Base or F Sport and matching the tire to the installed 18-inch or 19-inch wheel package.
Which Tire Size Is Right for The 2016 Lexus RC300
The 2016 Lexus RC300 uses two primary tire sizes, and the first step is identifying the exact sub-model and wheel diameter on the car. Both sizes are radial, but they do not serve the same fitment role: 235/45R18 applies to certain Base configurations, while 235/40R19 is used on the 19-inch setup, including the F Sport. Once the wheel package is confirmed, the decision shifts to comparing the available tire series and rim-width compatibility within that size.
A 235/40R19 size uses a 235-millimeter nominal section width, a 40-series aspect ratio, radial construction, and a 19-inch rim diameter. On the 2016 Lexus RC300, this size supports the coupe's lower-profile sport-oriented wheel package and is the size tied to the F Sport configuration. Available choices in this fitment include BFGoodrich blackwall radial products in the g-Force Phenom T/A series. This is the size to evaluate when the car already wears 19-inch wheels and the goal is to keep the intended profile and wheel relationship intact.
A 235/45R18 tire also carries a 235-millimeter nominal section width, but its 45-series profile is paired with an 18-inch rim. For the 2016 Lexus RC300, this size belongs to certain Base-model configurations using the 18-inch wheel package rather than the 19-inch setup. BFGoodrich offers this fitment in several blackwall radial series, including g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. It is the right size to compare when the car has 18-inch wheels and the buyer wants to stay with the proper rim diameter and tire profile family.
Sub-model fitment matters on the 2016 Lexus RC300 because tire size changes with the wheel package. The Base can use either of the two primary radial sizes, while the F Sport stays with the 19-inch fitment, so confirming the exact version of the car prevents ordering around the wrong rim diameter.

2016 Lexus RC300 Base
The 2016 Lexus RC300 Base can use either of the two primary radial tire sizes, depending on whether the car is equipped with 18-inch or 19-inch wheels. Tire selection starts with verifying the installed wheel diameter, then comparing the available blackwall performance-oriented choices in the matching size.
The 2016 Lexus RC300 F Sport uses the 235/40R19 radial fitment tied to its 19-inch wheel setup. That makes the decision more straightforward, with the focus shifting from size identification to choosing the right tire series and confirming wheel width compatibility.
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 2016 Lexus RC300?
The 2016 Lexus RC300 uses two primary tire sizes: 235/45R18 and 235/40R19. Both are radial fitments, but they are tied to different wheel packages and sub-model configurations rather than being interchangeable choices on the same wheel diameter.
The practical first step is checking the car's installed wheels before selecting a tire. A Base model may be equipped with either 18-inch or 19-inch wheels, while the F Sport uses the 19-inch setup, so the correct size depends on the exact configuration already on the car.
What size rim does a 2016 Lexus RC300 use?
A 2016 Lexus RC300 uses either an 18-inch or 19-inch rim, depending on the wheel package and sub-model. The 235/45R18 tire belongs to the 18-inch fitment, while the 235/40R19 tire belongs to the 19-inch fitment.
Wheel diameter should be confirmed before comparing tires, because the two RC300 sizes are not just different profiles but different rim diameters. Looking at the sidewall size on the current tire and verifying the actual wheel on the car is the safest way to avoid choosing a tire built for the wrong setup.
Do all 2016 Lexus RC300 sub-models use the same tire size?
No, the 2016 Lexus RC300 sub-models do not all use the same tire size. The Base can be equipped with either 235/45R18 or 235/40R19, while the F Sport uses 235/40R19.
That difference matters because the first tire decision is not brand or series but confirming the exact sub-model and wheel package. A buyer working from model name alone could easily end up comparing the wrong tires, so checking whether the car is a Base or F Sport is an important starting point.
Choosing the Right Tire
What should I consider when choosing a tire for a 2016 Lexus RC300?
Start with the correct tire size for the car's wheel package, then compare construction, rim-width compatibility, tire series, and intended use. For the 2016 Lexus RC300, both primary sizes are radial, so the choice is less about construction type and more about matching the right tire to the installed 18-inch or 19-inch wheel.
After size is confirmed, look at how the tire will be used and which product characteristics matter most to you. A buyer may prefer one series over another for general street driving, a sportier presentation, or wheel-width compatibility, but the right decision still begins with the exact fitment already on the car.
What sidewall styles are available for 2016 Lexus RC300 tires?
The available tires for the 2016 Lexus RC300 use a blackwall sidewall style. That gives the RC300 a clean modern appearance that suits the car's contemporary sport coupe character without introducing whitewall, stripe, or raised-letter styling.
Since sidewall treatment does not vary here, the real comparison shifts to tire series and fitment details within the correct size. Once the proper 18-inch or 19-inch setup is confirmed, buyers can focus on the differences between the available radial offerings rather than deciding among multiple appearance-driven sidewall options.
What tire series are available for the 2016 Lexus RC300?
The 2016 Lexus RC300 is served by BFGoodrich g-Force series options, including g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. The 18-inch fitment has the broadest series range, while the 19-inch fitment is centered on the g-Force Phenom T/A.
Series choice matters most after the size is settled, because each RC300 fitment does not have the same range of product options. Buyers comparing the 18-inch tires have more series variation to evaluate, while the 19-inch setup is more focused, making wheel compatibility and intended use more important than catalog breadth.
Restoration & Appearance
Which tire should I choose for a period-style 2016 Lexus RC300?
A period-style approach on a 2016 Lexus RC300 usually means staying with the correct factory-era size format and preserving the car's intended wheel-and-tire relationship. Since this RC300 uses modern metric radial sizes, keeping either 235/45R18 or 235/40R19 as appropriate maintains the contemporary sport coupe look the car was designed around.
Appearance on a newer collector car often comes down to avoiding mismatched wheel diameter or an unintended profile change. Matching the existing wheel package first, then choosing among the available blackwall g-Force series, keeps the presentation consistent without forcing the car into a style that does not suit its original era.
Does correct tire fitment matter for a 2016 Lexus RC300 restoration or preservation project?
Yes, correct tire fitment matters on a 2016 Lexus RC300 even in a preservation-minded project, because the tire size affects stance, wheel relationship, and the overall visual balance of the car. On this model, that starts with using the proper 18-inch or 19-inch tire size for the actual configuration.
Even though the RC300 is a modern vehicle, collectors still notice details that look out of place. A tire chosen only by width, or one mounted around the wrong rim diameter, can upset the presentation quickly, so verifying the exact wheel setup remains just as important as choosing a brand or series name.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2016 Lexus RC300?
Yes, modifications can affect tire fitment on a 2016 Lexus RC300. Aftermarket wheels, changes in wheel width, suspension lowering, alignment changes, or body modifications can all alter how a 235/45R18 or 235/40R19 tire sits in the wheel opening and how much clearance remains during steering and suspension travel.
A modified RC300 should be checked as an individual car rather than assumed to match stock fitment. Wheel diameter, wheel width, and available clearance around the fenders and suspension are the main points to verify before replacement, especially if the car no longer carries its original wheel and suspension setup.
What should I inspect before driving a 2016 Lexus RC300 on new tires?
Before driving a 2016 Lexus RC300 on new tires, inspect the wheels for the correct diameter and condition, confirm the tires are properly mounted, and check inflation pressure. It is also smart to look for any visible clearance issues around the fenders, liners, and suspension, especially when changing from worn tires to fresh ones.
A short first drive should be treated as a verification step rather than routine use. Pay attention to vibration, rubbing, pulling, or unusual noise, then recheck pressure and wheel hardware after the initial miles so any installation or fitment issue can be caught before regular driving resumes.
How often should tires on a 2016 Lexus RC300 be inspected?
Tires on a 2016 Lexus RC300 should be inspected regularly, with a quick visual check before driving and a closer inspection at routine service intervals. Look for uneven tread wear, sidewall cuts, bulges, cracking, embedded debris, and any signs of slow air loss that could affect road manners or tire life.
A car that sees limited use still needs attention, because age and storage conditions can matter as much as mileage. Checking pressure consistently and examining the tread and sidewalls a few times each season helps catch problems early, particularly on an RC300 that may spend stretches parked between drives.
