The 2010 Lexus GS350 sits in the middle ground between luxury sedan refinement and sharp rear-drive sport-sedan character, making tire choice more than a routine maintenance decision. Buyers looking at this generation often want to preserve the car’s composed ride while keeping the steering response and stance that define the GS line. Tire fitment for the 2010 Lexus GS350 centers on radial construction, with 225/50R17 and 245/40R18 sizes used depending on drivetrain and wheel setup. Available choices range from straightforward blackwall performance radials to 18-inch options with redline or raised white letter styling. The right selection starts with confirming the exact sub-model and wheel diameter already on the car.
Which Tire Size Is Right for The 2010 Lexus GS350
The 2010 Lexus GS350 uses two primary tire sizes, and the correct choice depends on both sub-model and wheel diameter. AWD models use a 17-inch setup, while RWD versions may use either 17-inch or 18-inch tires. Before comparing brands, sidewall styles, or tire series, the first step is confirming whether the car is AWD or RWD and then verifying the wheel diameter actually installed.
The 225/50R17 size identifies a metric radial tire with a 225-millimeter section width, a 50-series aspect ratio, and fitment for a 17-inch rim. On the 2010 Lexus GS350, this is a modern radial size used on the 17-inch wheel setup and is the tire size shared by AWD models and some RWD configurations. Available choices in this size focus on blackwall performance-oriented radials from BFGoodrich and Nitto across the g-Force Comp 2 AS, g-Force Sport Comp 2, and NT555 G2 series. It is the right place to focus if the car retains 17-inch wheels and the goal is matching the proper wheel diameter and overall fitment profile.
The 245/40R18 size is a metric radial with a 245-millimeter section width, a 40-series aspect ratio, and an 18-inch rim diameter. On the 2010 Lexus GS350, this size applies to certain RWD configurations using the larger 18-inch wheel setup, making wheel confirmation essential before selection. Product choices are broader here, including blackwall options from BFGoodrich, Nitto, and M&H Racemaster, plus Pro-Trac Street Pro III versions with redline or raised white letter sidewalls. This size is the one to evaluate when the car already has 18-inch wheels and the owner wants either a conventional modern presentation or a more distinctive sidewall treatment.
Sub-model fitment matters on the 2010 Lexus GS350 because tire size changes with drivetrain and wheel setup. AWD fitment is straightforward, while RWD versions require closer attention since they may use either a 17-inch or 18-inch tire package.

2010 Lexus GS350 (AWD)
The 2010 Lexus GS350 AWD uses the 225/50R17 radial size, which keeps selection centered on the 17-inch wheel package. That makes the decision less about multiple fitments and more about choosing among available blackwall performance radials with the right wheel compatibility.
The 2010 Lexus GS350 RWD can use either 225/50R17 or 245/40R18, so confirming the actual wheel diameter on the car is the critical first step. Once that is established, tire choice shifts to comparing available brands, performance-oriented series, and, in the 18-inch size, sidewall styling 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.

Available 2010 Lexus GS350 tire choices span 17-inch and 18-inch radial fitments from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac. The main differences in the product grid are tire series, blackwall versus redline or raised white letter styling, and wheel-width compatibility within each size.
Tire questions for the 2010 Lexus GS350 usually come down to sub-model fitment, 17-inch versus 18-inch wheel setups, and how to compare the available radial tire choices. The FAQs below focus on size, rim fitment, styling differences, product selection, and road-use checks.
Tire Size & Fitment
What tire size fits a 2010 Lexus GS350?
The 2010 Lexus GS350 uses two primary tire sizes: 225/50R17 and 245/40R18. The 225/50R17 size applies to AWD models and also appears on some RWD versions, while 245/40R18 is used on certain RWD configurations with 18-inch wheels.
The practical decision is not choosing between two interchangeable sizes at random. Start by identifying whether the car is AWD or RWD, then confirm the wheel diameter already installed, because a 17-inch tire and an 18-inch tire are matched to different wheels and should be selected accordingly.
What size rim does a 2010 Lexus GS350 use?
A 2010 Lexus GS350 uses either a 17-inch or 18-inch rim, depending on the tire size and vehicle configuration. The 225/50R17 tire is matched to a 17-inch rim, while the 245/40R18 tire is matched to an 18-inch rim.
Wheel diameter should be verified before ordering tires, especially on a used GS350 that may have had wheels changed over time. Checking the sidewall size already on the car and confirming the actual wheel measurement helps prevent selecting a tire that matches the model year but not the wheel package currently fitted.
Why does the 2010 Lexus GS350 have more than one tire size?
The 2010 Lexus GS350 has more than one tire size because fitment varies by drivetrain and wheel setup. AWD models use 225/50R17, while RWD versions may be equipped with either 225/50R17 or 245/40R18 depending on the wheel package on the car.
That means size selection begins with configuration, not preference. An owner looking at replacement tires should confirm the exact sub-model and then inspect the current wheels before comparing brands or tread styles, since the correct tire for a 17-inch GS350 is not the same as the correct tire for an 18-inch setup.
Choosing the Right Tire
What should I consider when choosing a 2010 Lexus GS350 tire?
Start with the correct size for the car’s drivetrain and wheel diameter: 225/50R17 for AWD and some RWD applications, or 245/40R18 for certain RWD setups. From there, compare radial construction details such as tire series, sidewall style, rim-width compatibility, and, where stated, load and weight specifications.
A GS350 used mainly for normal street driving may call for a different product character than one built around sharper performance feel or a more distinctive visual presentation. Matching the tire to the car’s actual wheel setup and intended use is usually more important than focusing on brand alone.
What sidewall styles are available for 2010 Lexus GS350 tires?
Sidewall styling depends on tire size. The 225/50R17 options are blackwall radials, while the 245/40R18 range includes blackwall choices along with redline and RWL, or raised white letter, versions in the Pro-Trac Street Pro III series.
That gives 18-inch RWD owners more room to shape the car’s visual character, from a clean modern blackwall look to a more expressive sidewall treatment. The right choice still needs to begin with the correct tire size, since sidewall style should follow fitment rather than determine it.
What brands offer tires for the 2010 Lexus GS350?
Tires for the 2010 Lexus GS350 are available from BFGoodrich and Nitto in the 17-inch size, while the 18-inch size adds M&H Racemaster and Pro-Trac to BFGoodrich and Nitto. The available series include g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, NT555 G2, Drag Radial, and Street Pro III.
Those brand and series differences matter because they shape the kinds of products you can compare within the correct size. Once the wheel diameter is confirmed, the choice becomes one of tire character, sidewall presentation, and wheel-width compatibility rather than simply picking any tire that fits the model name.
Restoration & Appearance
Which tire should I choose for a period-style 2010 Lexus GS350?
A period-style 2010 Lexus GS350 tire choice usually starts with keeping the correct original-size format already on the car, either 225/50R17 or 245/40R18. Since this is a modern luxury sport sedan, the most natural period-style presentation generally comes from a blackwall radial that suits the car’s factory-era appearance.
An 18-inch RWD setup does offer more visual variety, including redline and raised white letter choices, but those create a more customized look than a restrained original-era presentation. Owners aiming for the closest appearance to showroom-era character should prioritize correct size, wheel diameter, and understated sidewall styling.
How does tire construction affect the appearance of a restored 2010 Lexus GS350?
Tire construction is straightforward on the 2010 Lexus GS350 because the primary fitments are radial. That means the appearance differences come less from bias-ply versus radial choice and more from sidewall treatment, tire series, and whether the car wears a 17-inch or 18-inch wheel setup.
A blackwall radial gives the GS350 the clean, contemporary look most buyers associate with this era, while redline or raised white letter options on 245/40R18 create a more personalized visual statement. For a restoration-minded owner, preserving the correct size and wheel relationship matters more than chasing novelty.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2010 Lexus GS350?
Yes, modifications can affect tire fitment on a 2010 Lexus GS350 even when the tire size itself is correct. Aftermarket wheels, changed wheel widths, altered offsets, lowered suspension, or body and fender changes can all influence how a 225/50R17 or 245/40R18 tire sits and clears the car.
A modified GS350 should be checked for wheel diameter, wheel width, and steering or suspension clearance before replacement tires are chosen. Tire size alone does not confirm compatibility once the original setup has been changed, so measuring the actual wheel package on the car is the safest starting point.
What should I inspect before driving a 2010 Lexus GS350 on new tires?
Before driving a 2010 Lexus GS350 on new tires, inspect the wheels for damage, confirm the tire size matches the wheel diameter, and check that inflation is set appropriately for the tire being used. It is also wise to look over the suspension and alignment condition so the new tires are not compromised immediately.
A short road test should include attention to vibration, pulling, rubbing, and any unusual steering response. The car should also be rechecked for proper clearance at full steering lock, especially if it has non-original wheels or suspension changes that could alter how the tire fits in the wheelwell.
How often should tires on a 2010 Lexus GS350 be inspected?
Tires on a 2010 Lexus GS350 should be inspected regularly, not just when tread appears low. A quick visual check for uneven wear, cuts, bulges, embedded debris, or air loss is worthwhile before longer drives, and collector or low-use cars deserve extra attention because time can age tires even when miles stay low.
Pressure should be monitored consistently, and any change in ride quality or steering feel should prompt a closer look. A GS350 that sits for extended periods also benefits from checking for flat spotting and sidewall aging, since appearance alone does not always reflect a tire’s true road-ready condition.
