The 2011 Lexus GS350 sits in the modern sport-luxury sedan category, blending rear- or all-wheel-drive confidence with the sharper handling and refined road manners buyers expect from the GS line. It is a car that rewards attention to chassis balance, which makes correct tire selection especially important. Tire fitment on the 2011 Lexus GS350 centers on radial construction, with 225/50R17 used across the range and 245/40R18 also used on certain RWD applications. That creates a real choice around wheel diameter, tire series, and sidewall style rather than old-car bias-ply versus radial decisions. The right selection starts with confirming the exact drivetrain and wheel setup already on the car.
Which Tire Size Is Right for The 2011 Lexus GS350
The 2011 Lexus GS350 uses two primary tire sizes, and the correct one depends on both sub-model and wheel diameter. AWD applications use 225/50R17, while RWD versions may use either 225/50R17 or 245/40R18, so the first step is confirming whether the car is AWD or RWD and then verifying whether it has 17-inch or 18-inch wheels before selecting a tire.
225/50R17 is a metric radial size in which 225 identifies the section width in millimeters, 50 is the aspect ratio, R indicates radial construction, and 17 is the wheel diameter in inches. On the 2011 Lexus GS350, this size is part of the core fitment and is especially important for AWD applications. Available choices in this size come from BFGoodrich and Nitto, with blackwall styling and several series including g-Force Comp 2 AS, g-Force Sport Comp 2, and NT555 G2. It is the size to evaluate when the car is on 17-inch wheels and the goal is matching the intended wheel setup with the right product character.
245/40R18 is a metric radial size where 245 is the nominal section width in millimeters, 40 is the aspect ratio, R denotes radial construction, and 18 identifies the wheel diameter in inches. For the 2011 Lexus GS350, this size appears on certain RWD configurations and should not be treated as universal across every version of the car. Product choices are broader here, including BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac, with blackwall, redline, and raised white letter sidewall presentations. This is the size to consider after confirming an 18-inch wheel package and deciding whether the focus is street use, appearance, or a more specialized tire type.
Sub-model fitment matters on the 2011 Lexus GS350 because tire size changes with drivetrain and wheel package. AWD fitment is more straightforward, while RWD cars require a closer look at the wheel diameter already on the vehicle before choosing a tire.

2011 Lexus GS350 (AWD)
The 2011 Lexus GS350 AWD uses 225/50R17 radial tires, making fitment more direct than on the RWD version. Tire selection then becomes a matter of choosing the right 17-inch product within that size, with attention to brand, series, and wheel compatibility.
The 2011 Lexus GS350 RWD can use either 225/50R17 or 245/40R18 radial tires, depending on the wheel setup on the car. That makes wheel-diameter confirmation the key first step before comparing available tire series, sidewall treatments, or more specialized 18-inch 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 2011 Lexus GS350?
The 2011 Lexus GS350 uses two primary tire sizes: 225/50R17 and 245/40R18. The AWD model uses 225/50R17, while the RWD model may use either 225/50R17 or 245/40R18 depending on the wheel package on the car.
That means the correct answer starts with confirming both drivetrain and actual wheel diameter. A GS350 that has been fitted with different wheels over time may no longer match the original setup, so checking the existing tire size and measuring the wheel before purchasing is the safest way to avoid a mismatch.
What size rim does a 2011 Lexus GS350 use?
A 2011 Lexus GS350 uses either a 17-inch or 18-inch rim, depending on the tire size and sub-model configuration. The 225/50R17 tire uses a 17-inch rim, while the 245/40R18 tire uses an 18-inch rim.
Rim diameter should be verified before anything else because a 17-inch tire cannot be mounted on an 18-inch wheel, and the reverse is equally true. On an RWD GS350, that matters even more because both tire sizes appear within the model range, so wheel confirmation comes before brand or series selection.
Do all 2011 Lexus GS350 sub-models use the same tire size?
No, not all 2011 Lexus GS350 sub-models use the same tire size. The AWD version uses 225/50R17, while the RWD version may use 225/50R17 or 245/40R18 depending on the wheel setup.
This difference matters because the tire decision is not only about the model name but also about the exact configuration sitting in the garage. A buyer with an RWD car should confirm the current wheel diameter and existing tire markings before comparing products, especially if the car may have received replacement wheels at some point.
Choosing the Right Tire
What should I consider when choosing a tire for a 2011 Lexus GS350?
Start with the correct size for the car’s drivetrain and wheel diameter, since the 2011 Lexus GS350 uses either 225/50R17 or 245/40R18. After size is confirmed, compare radial tire series, sidewall style, rim-width compatibility, and any load information that is relevant to how the car is driven.
A street-driven GS350 may call for a different product character than a car chosen for more aggressive use or a more appearance-driven presentation. The best comparison points are wheel fit, intended use, and whether the owner wants a straightforward blackwall tire or something more distinctive in the available 18-inch options.
What sidewall styles are available for 2011 Lexus GS350 tires?
Sidewall style depends on tire size. In the available selections for the 2011 Lexus GS350, 225/50R17 choices are blackwall, while 245/40R18 includes blackwall as well as redline and RWL, or raised white letter, sidewall treatments.
That gives 18-inch RWD applications more visual variety than the 17-inch fitment. Sidewall style should still come after confirming the proper size and wheel diameter, since an appearance preference does not override fitment, but it can make a meaningful difference when the goal is giving the car a more distinctive presentation.
What brands offer tires for the 2011 Lexus GS350?
Tires for the 2011 Lexus GS350 are available from BFGoodrich, Nitto, M&H Racemaster, and Pro-Trac. Brand coverage varies by size, with 225/50R17 centered on BFGoodrich and Nitto, while 245/40R18 adds M&H Racemaster and Pro-Trac to the mix.
Brand is only one part of the decision, since different products also vary by tire series, sidewall presentation, and wheel-width compatibility. Once the correct size is confirmed, comparing the overall character of the available options is more useful than focusing on the brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 2011 Lexus GS350?
A period-style approach on a 2011 Lexus GS350 usually starts with keeping the correct original-size format already used on the car, whether that is 225/50R17 or 245/40R18. Since this is a modern radial-fitment sedan rather than a bias-ply-era vehicle, the visual decision is more about sidewall treatment and tire character than vintage construction style.
Blackwall options maintain the most understated look, while certain 245/40R18 offerings introduce redline or raised white letter styling for a more assertive presentation. Appearance should still follow correct wheel diameter and proper size selection, especially on RWD cars where both 17-inch and 18-inch fitments exist within the same model year.
How does tire construction affect the appearance of a restored 2011 Lexus GS350?
On a 2011 Lexus GS350, construction does not create the old bias-ply versus radial appearance divide seen on vintage cars because the fitment is radial throughout. The visible difference comes more from sidewall styling, tire series, and the visual stance created by either the 17-inch or 18-inch wheel-and-tire combination.
That means a restoration-minded owner should focus on preserving the car’s intended overall look by matching the correct size to the correct wheel package. On 18-inch setups, redline or raised white letter sidewalls can change the car’s presentation noticeably, while blackwall tires keep the look closer to a restrained sport-luxury theme.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2011 Lexus GS350?
Yes, modifications can affect tire fitment on a 2011 Lexus GS350. Aftermarket wheels, suspension changes, altered ride height, or body modifications can change the space available for a 225/50R17 or 245/40R18 tire even when the size itself is correct for a stock configuration.
Any GS350 with non-stock wheels should have wheel diameter and width checked before replacing tires. Clearance at the fender, inner wheelhouse, and steering components also deserves attention, especially on the front axle, because a tire that suits a factory setup may need closer verification once the car has been altered.
What should I inspect before driving a 2011 Lexus GS350 on new tires?
Before driving a 2011 Lexus GS350 on new tires, inspect the wheels for damage, confirm the tire size matches the wheel diameter, and check that inflation is set correctly for the installation. It also makes sense to look over the valve stems and verify that each tire is seated properly on the rim.
A short test drive should be followed by another look at air pressure and any sign of rubbing or unusual vibration. On an RWD car in particular, this is a good time to confirm that the chosen size truly matches the wheel package already on the vehicle rather than assuming every GS350 uses the same setup.
How often should tires on a 2011 Lexus GS350 be inspected?
Tires on a 2011 Lexus GS350 should be inspected regularly, not only when replacement time arrives. A visual check for uneven wear, cuts, bulges, cracking, or slow air loss is worthwhile on any driven car, and it becomes even more important if the vehicle sees limited use or long storage periods.
Routine inspection helps catch problems before they affect ride quality or safety on the road. Owners should also keep an eye on tread condition and watch for wear patterns that may point to alignment or suspension issues, since even the correct 225/50R17 or 245/40R18 tire will not perform as intended on a neglected chassis.
