The 2014 Lexus GS350 sits in the modern sport-luxury sedan category, blending a refined grand-touring character with sharper handling than many midsize luxury cars of its era. Tire choice matters more here than it does on a softer touring sedan because wheel size, profile, and drivetrain configuration shape both appearance and road feel. The 2014 Lexus GS350 uses radial tires, with fitments ranging from 225/50R17 and 235/45R18 on standard models to 19-inch staggered sizing on certain F Sport configurations. Available choices center on blackwall performance-oriented series from BFGoodrich and Nitto. The key is confirming the exact sub-model and wheel setup before selecting a replacement.
Which Tire Size Is Right for The 2014 Lexus GS350
The 2014 Lexus GS350 uses four primary tire sizes, and the right one depends on the exact sub-model and wheel package. Standard AWD and FWD configurations use either 225/50R17 or 235/45R18, while F Sport models move to 19-inch fitments, including a staggered front-and-rear setup on RWD cars. Before choosing a tire, confirm both the sub-model and the wheel diameter currently on the car.
225/50R17 is a metric radial size in which 225 identifies the nominal section width in millimeters, 50 is the aspect ratio, R marks radial construction, and 17 is the wheel diameter in inches. On the 2014 Lexus GS350, this size suits standard 17-inch applications rather than the sport-oriented 19-inch F Sport setup. Available choices in this size are blackwall radials from BFGoodrich and Nitto across g-Force and NT555 G2 series. This size is the right place to start if the car has 17-inch wheels and the goal is to stay with its proper wheel diameter and profile range.
235/45R18 is a metric radial size with a 235-millimeter nominal section width, a 45-series profile, and an 18-inch rim diameter. On the 2014 Lexus GS350, it belongs to standard non-F Sport fitments that use 18-inch wheels rather than the lower-profile 19-inch F Sport arrangement. Product choices are blackwall radials from BFGoodrich, including g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. This size makes sense when the car is equipped with 18-inch wheels and the owner wants to compare performance-oriented options within that original fitment category.
235/40R19 is a metric radial size that uses a 235-millimeter nominal section width, a shorter 40-series aspect ratio, and a 19-inch wheel diameter. On the 2014 Lexus GS350, this size is tied to F Sport applications and serves as the front fitment on the RWD staggered setup. The available product in this size is a blackwall BFGoodrich g-Force Phenom T/A radial, which keeps the focus on a modern performance-oriented presentation. This is the size to evaluate when the car has 19-inch front wheels and the buyer needs to preserve the intended front fitment profile.
265/35R19 is a metric radial size with a wider 265-millimeter nominal section width, a 35-series profile, and a 19-inch rim diameter. On the 2014 Lexus GS350, it serves as the rear tire size for the RWD F Sport staggered arrangement rather than a universal fitment for every GS350. Blackwall choices in this size include BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2. This size should be chosen only after confirming a 19-inch rear wheel setup, since it is part of a wider rear application rather than a standard square replacement.
Sub-model fitment matters on the 2014 Lexus GS350 because tire size changes with drivetrain and F Sport configuration. Standard AWD and FWD models use 17-inch or 18-inch fitments, while F Sport models move to 19-inch tires, including a staggered front-and-rear setup on RWD versions.

2014 Lexus GS350 (AWD)
The 2014 Lexus GS350 (AWD) uses standard radial fitments on either 17-inch or 18-inch wheels rather than the 19-inch F Sport setup. Tire selection here centers on confirming which wheel diameter is on the car, then choosing among blackwall performance-oriented radial options in the matching size.
The 2014 Lexus GS350 (FWD) follows the same basic tire-fitment pattern as the AWD model, using radial tires in 17-inch or 18-inch sizes. The main decision is confirming the installed wheel package so the replacement tire matches the car's current rim diameter and profile.
The 2014 Lexus GS350 F Sport (AWD) uses a 19-inch radial fitment that separates it from the standard GS350 configurations. Tire choice here is more about preserving the correct F Sport wheel-and-profile setup than deciding between multiple standard wheel diameters.
The 2014 Lexus GS350 F Sport (RWD) Front uses a dedicated 19-inch front radial size as part of a staggered arrangement. Front tire replacement should be handled as one half of that staggered setup, with attention to maintaining the proper front sizing rather than treating the car like a square-fitment sedan.
The 2014 Lexus GS350 F Sport (RWD) Rear uses a wider 19-inch rear radial tire that complements the narrower front size. Rear tire selection should keep that staggered layout in mind, especially if the car has aftermarket wheels or any suspension changes that could affect rear clearance.
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 2014 Lexus GS350 Tires for Sale
Available 2014 Lexus GS350 tire choices are all blackwall radials, with BFGoodrich and Nitto offerings across g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2 series. The main comparison points are size, wheel diameter, series, and rim-width compatibility where stated.
Owners usually need to sort out exact tire size, wheel diameter, and F Sport versus standard GS350 fitment before comparing brands or series. Common questions also center on staggered 19-inch setups, appearance, and what to inspect before regular road use.
Tire Size & Fitment
What tire size fits a 2014 Lexus GS350?
The 2014 Lexus GS350 uses four primary tire sizes: 225/50R17, 235/45R18, 235/40R19, and 265/35R19. Standard AWD and FWD GS350 models use the 17-inch or 18-inch sizes, while F Sport models use 19-inch fitments, including a staggered arrangement on RWD F Sport versions with different front and rear sizes.
The important next step is matching the tire to the exact sub-model and wheel package on the car. A standard GS350 and an F Sport do not use the same sizing approach, and an RWD F Sport should not be treated like a square-fitment setup without checking the wheels already installed.
What size rim does a 2014 Lexus GS350 use?
A 2014 Lexus GS350 can use 17-inch, 18-inch, or 19-inch rims depending on configuration. The 225/50R17 tire uses a 17-inch rim, the 235/45R18 uses an 18-inch rim, and both 235/40R19 and 265/35R19 use 19-inch rims for F Sport applications.
Wheel diameter should be confirmed before anything else because the GS350 does not use one universal rim size across all versions. Reading the current tire sidewall is the quickest first check, but that should also be compared with the actual sub-model and whether the car has standard or F Sport wheels.
Why does the 2014 Lexus GS350 have more than one tire size?
The 2014 Lexus GS350 has more than one tire size because fitment changes across standard and F Sport configurations, and because some versions use different wheel diameters. Standard GS350 models use 17-inch or 18-inch sizes, while F Sport fitment moves to 19-inch tires, including a staggered front-and-rear layout on RWD F Sport cars.
That means tire selection starts with the exact version of the car, not just the model name on the trunk. A replacement should match the wheel package and setup already on the vehicle unless the owner is intentionally reworking the wheel-and-tire combination and checking all related clearance and compatibility details.
Choosing the Right Tire
What should I consider when choosing a 2014 Lexus GS350 tire?
Start with the correct size and rim diameter for the exact 2014 Lexus GS350 configuration. This car uses several radial sizes, and the right choice depends on whether it is a standard AWD or FWD model or an F Sport with 19-inch fitment, including a staggered setup on some RWD cars.
After confirming fitment, compare tire series, brand, sidewall presentation, and any stated rim-width or load details that apply to that size. The best choice depends on whether the priority is maintaining the existing wheel package, preserving the F Sport staggered layout, or selecting among the available performance-oriented radial options.
What brands offer tires for the 2014 Lexus GS350?
Tires for the 2014 Lexus GS350 are available from BFGoodrich and Nitto in the sizes covered here. BFGoodrich appears across several GS350 fitments and series, while Nitto is available in selected sizes such as 225/50R17 and 265/35R19.
Brand choice should come after the size and wheel package are settled, since not every brand appears in every GS350 fitment. Once the correct size is confirmed, compare the available series within that size rather than assuming the same mix of products exists across the 17-inch, 18-inch, and 19-inch applications.
What tire series are available for the 2014 Lexus GS350?
Available 2014 Lexus GS350 tire series include g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Nitto NT555 G2. These series appear across different GS350 sizes, so the exact mix depends on whether the car uses 17-inch, 18-inch, or 19-inch fitment.
Series selection is useful when comparing tire character within the correct size, but it should not replace the basic fitment check. A 19-inch F Sport front or rear size may have fewer choices than a standard 17-inch or 18-inch setup, so confirm the size first and then compare the series actually offered in that application.
Restoration & Appearance
Which tire should I choose for a period-style 2014 Lexus GS350?
A period-style approach for a 2014 Lexus GS350 usually means staying with the original fitment type for the exact configuration already on the car. Since the GS350 uses modern radial sizes, the most faithful starting point is preserving the correct wheel diameter and, on F Sport RWD models, keeping the staggered front-and-rear arrangement intact.
Appearance on this car comes more from maintaining the proper profile and stance than from vintage-style sidewall treatments. Blackwall tires suit the product mix available here, so the practical decision is choosing the correct size and series while keeping the sedan's intended visual balance rather than chasing an unrelated retro look.
Does correct tire fitment matter for a 2014 Lexus GS350 restoration?
Correct tire fitment matters on a 2014 Lexus GS350 because wheel diameter, sidewall profile, and staggered versus square setup all influence how the car sits and drives. A standard GS350 on 17-inch or 18-inch tires presents differently from an F Sport on 19-inch wheels, especially when the RWD F Sport uses different front and rear sizes.
Using the proper fitment also helps preserve the character of the specific version being refreshed. Anyone restoring or cosmetically reconditioning a GS350 should verify the exact sub-model and wheel package first, then select tires that match that configuration rather than choosing by model name alone.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 Lexus GS350?
Yes, modifications can affect tire fitment on a 2014 Lexus GS350. Aftermarket wheels, suspension changes, altered ride height, and non-original offsets can all change how a 225/50R17, 235/45R18, 235/40R19, or 265/35R19 tire sits within the wheelwell and how much clearance remains during steering or suspension travel.
That is especially important on F Sport RWD cars with staggered 19-inch tires, because the front and rear are already different from the factory fitment pattern used on standard models. Checking wheel width, wheel diameter, and visible clearance before replacement helps avoid choosing a tire that only matches the sidewall size on paper.
What should I inspect before driving a 2014 Lexus GS350 on new tires?
Before driving a 2014 Lexus GS350 on new tires, inspect the wheels for correct diameter and condition, confirm the replacement sizes match the car's actual setup, and check that the tires are mounted in the proper positions on any staggered F Sport RWD arrangement. Tire pressure should also be set appropriately before regular road use.
A quick walkaround afterward is worth doing as well. Look for uneven clearance, signs of rubbing, and any unusual steering feel or vibration during the first miles, especially if the GS350 has changed hands, received aftermarket wheels, or has had suspension work that could alter how the new tires sit on the car.
How often should tires on a 2014 Lexus GS350 be inspected?
Tires on a 2014 Lexus GS350 should be inspected regularly, not just when tread looks low. A monthly check for pressure, visible damage, uneven wear, punctures, sidewall cuts, and air loss is a smart routine, and it becomes even more important on cars with low-profile 18-inch or 19-inch tires where damage can be easier to overlook.
Inspection should also happen before longer drives or after any impact with potholes or road debris. On an F Sport with staggered fitment, pay attention to front and rear wear separately because the sizes differ, and verify that each tire remains in the correct position on the vehicle.
