The 2016 Lexus GS350 sits in the modern sport-sedan category where ride quality, sharp response, and clean executive styling all matter at once. In this generation, the GS350 blends Lexus refinement with a more athletic chassis character, which makes tire choice especially important to how the car looks and feels on the road. Fitment depends on configuration, with the Base model using 235/45R18, while F Sport setups move to 19-inch radial sizes including a staggered 235/40R19 front and 265/35R19 rear arrangement. Available choices center on blackwall radial performance tires from BFGoodrich and Nitto, so the real task is matching the correct size and wheel setup to the exact version of the car.
Which Tire Size Is Right for The 2016 Lexus GS350
The 2016 Lexus GS350 uses three primary tire sizes, and the correct one depends on the exact sub-model and wheel setup. The Base model uses an 18-inch radial tire, while F Sport configurations use 19-inch radials, including a staggered front and rear arrangement on the rear-wheel-drive version. Before choosing a tire, confirm whether the car is Base or F Sport and verify whether it carries 18-inch or 19-inch wheels.
235/45R18 is a metric radial size that uses a 235-millimeter section width, a 45-series aspect ratio, and an 18-inch rim diameter. On the 2016 Lexus GS350, this size applies to the Base model and supports the balance of comfort and handling expected from a modern luxury sport sedan. Available choices in this size come from BFGoodrich in blackwall designs across the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. It is the size to evaluate when retaining the Base model wheel setup and comparing product character within the same basic fitment.
235/40R19 is a metric radial size with a 235-millimeter section width, a lower 40-series profile, and a 19-inch rim diameter. This size serves the F Sport fitment and also functions as the front tire size on the rear-wheel-drive staggered setup, giving it a more performance-oriented role than the 18-inch Base fitment. Product choice in this size centers on a blackwall BFGoodrich g-Force Phenom T/A. It should be selected only after confirming that the GS350 uses the 19-inch F Sport wheel package and that the tire is being placed in the correct front position where applicable.
265/35R19 is a wider metric radial size that combines a 265-millimeter section width with a 35-series profile on a 19-inch rim. On the 2016 Lexus GS350, it is the rear tire size for the F Sport rear-wheel-drive staggered configuration, where it works with a narrower 235/40R19 front tire. Available blackwall choices include BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, and the Nitto NT555 G2. This is the size to focus on when the car has the staggered 19-inch rear setup and the goal is preserving the intended front-to-rear sizing relationship.
Tire fitment on the 2016 Lexus GS350 changes by sub-model and, in F Sport rear-wheel-drive form, by axle position as well. Checking the exact configuration matters because the car may use either an 18-inch square setup or a 19-inch arrangement with different front and rear tire sizes.

2016 Lexus GS350 Base
The 2016 Lexus GS350 Base uses a single 235/45R18 radial tire size. That makes selection more straightforward, with the main decision centered on comparing available blackwall performance-oriented tires while keeping the 18-inch wheel setup in place.
The 2016 Lexus GS350 F Sport (AWD) uses 235/40R19 as its primary tire size. Tire selection starts with confirming the 19-inch F Sport wheel package, then comparing the available radial option within that lower-profile fitment.
The 2016 Lexus GS350 F Sport (RWD) Front uses 235/40R19. This front fitment is part of a staggered arrangement, so replacement planning should keep the front size matched to the proper rear tire size rather than treating the car as a same-size setup all around.
The 2016 Lexus GS350 F Sport (RWD) Rear uses 265/35R19. Because this is the rear portion of a staggered setup, tire choice should preserve the intended rear width and be checked against the wheel position before selecting among the available blackwall 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.
Best 2016 Lexus GS350 Tires for Sale
Available 2016 Lexus GS350 tires center on blackwall radial performance options, primarily from BFGoodrich, with Nitto also offered in 265/35R19. Buyers can compare fitment by size, tire series, rim-width specifications where stated, and load or weight details where those differences are relevant.
Common questions for the 2016 Lexus GS350 usually come down to identifying the right size by sub-model, understanding the 18-inch versus 19-inch setups, and choosing among available radial performance tires. The details below also cover staggered fitment, wheel confirmation, appearance, and road-use checks.
Tire Size & Fitment
What tire size fits a 2016 Lexus GS350?
The 2016 Lexus GS350 uses three primary tire sizes: 235/45R18, 235/40R19, and 265/35R19. The Base model uses 235/45R18, the F Sport (AWD) uses 235/40R19, and the F Sport (RWD) uses a staggered setup with 235/40R19 in front and 265/35R19 in the rear.
That means the first step is identifying the exact version of the car rather than choosing by model name alone. A Base car on 18-inch wheels takes a different fitment approach than an F Sport on 19s, and the rear-wheel-drive F Sport also needs the correct front-to-rear pairing preserved when replacing tires.
What size rim does a 2016 Lexus GS350 use?
A 2016 Lexus GS350 uses either an 18-inch or 19-inch rim, depending on configuration. The 235/45R18 fitment uses an 18-inch wheel, while both 235/40R19 and 265/35R19 use 19-inch wheels on F Sport applications.
Wheel diameter is the first thing to confirm before comparing tires, especially if the car has changed hands or has been modified. An 18-inch Base setup and a 19-inch F Sport setup are not interchangeable by size alone, and the staggered rear-wheel-drive arrangement also requires confirming which wheel position you are replacing.
Why does the 2016 Lexus GS350 have more than one tire size?
The 2016 Lexus GS350 has more than one tire size because fitment changes by sub-model and wheel package. The Base model uses 235/45R18, while F Sport versions move to 19-inch tires, and the rear-wheel-drive F Sport adds a wider 265/35R19 rear tire for a staggered layout.
That variation matters because the correct tire is tied to the car's specific setup, not just the GS350 badge. Checking the sub-model, wheel diameter, and whether the car uses the same size at all four corners or a front-and-rear stagger will keep replacement choices aligned with the existing wheel arrangement.
Choosing the Right Tire
What should I consider when choosing a 2016 Lexus GS350 tire?
Start with the exact tire size that matches the car's configuration: 235/45R18 for Base, 235/40R19 for F Sport (AWD), or the 235/40R19 front and 265/35R19 rear combination for F Sport (RWD). From there, compare available radial options by tire series, load details where stated, weight, and rim-width compatibility where that information is given.
A good choice depends on how the car is used and how closely the replacement should match the current setup. A Base sedan often invites a different selection focus than a staggered F Sport, and any tire should be checked against the wheel size and position before treating similar-looking metric sizes as interchangeable.
What sidewall styles are available for 2016 Lexus GS350 tires?
The available 2016 Lexus GS350 tire choices in these sizes use a blackwall sidewall style. That applies across the 18-inch and 19-inch fitments offered here, including BFGoodrich selections and the Nitto option in 265/35R19.
For this car, the sidewall decision is straightforward because the visual presentation stays modern and understated rather than branching into whitewall or raised-letter appearance options. The more meaningful differences are the exact tire size, whether the car uses a square or staggered setup, and which tire series best suits the intended driving style.
What brands offer tires for the 2016 Lexus GS350?
BFGoodrich offers tires for all three 2016 Lexus GS350 fitments covered here, and Nitto is available in 265/35R19. Across those sizes, the main BFGoodrich series include g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A, all in radial blackwall form.
Brand choice should come after the fitment basics are settled. A Base model owner comparing 235/45R18 options has a different set of decisions than an F Sport rear-wheel-drive owner replacing only the rear 265/35R19 tires, so size, axle position, and wheel compatibility still come before brand preference.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2016 Lexus GS350?
Yes. A 2016 Lexus GS350 can be affected by aftermarket wheels, suspension changes, altered ride height, or previous tire substitutions, even when the replacement tire matches one of the standard sizes. That matters most on F Sport cars using 19-inch wheels and especially on the staggered rear-wheel-drive setup.
Checking the actual wheel diameter and width on the car is the safest starting point before choosing a tire. Clearance at the fender, suspension, and steering range should also be confirmed, because a modified GS350 may no longer have the same margin as a stock example using the original-style wheel and tire layout.
What should I inspect before driving a 2016 Lexus GS350 on new tires?
Inspect the wheel size, the exact tire size installed at each position, and the general condition of the wheels before driving a 2016 Lexus GS350 on new tires. It is also smart to look for uneven wear, visible damage, air loss, and any sign that the car may have been running mismatched sizes, especially on staggered F Sport models.
Road use is smoother when the basics are checked early rather than after a problem appears. Tire pressure, tread condition on any remaining paired tire, and suspension condition all influence how a GS350 feels, and front-to-rear consistency is particularly important when the car uses separate 235/40R19 front and 265/35R19 rear fitments.
How often should tires on a 2016 Lexus GS350 be inspected?
Tires on a 2016 Lexus GS350 should be inspected regularly for pressure loss, tread wear, cuts, bulges, and sidewall aging. Even on a modern sedan, routine visual checks matter because incorrect inflation or unnoticed damage can change ride quality, steering feel, and wear patterns long before a tire actually fails.
A practical habit is to inspect the tires before longer drives and anytime the car begins to pull, vibrate, or feel different in corners. Cars with staggered 19-inch fitment deserve extra attention, since the wider rear tires and lower-profile fronts should stay in their proper positions and be monitored as separate sizes rather than rotated casually.
