The 2009 Lexus GS460 sits at an interesting point in the GS story, combining V8-powered luxury-sport character with the sharp, low-profile stance expected of a modern performance sedan. Buyers looking at one today are usually balancing road manners, appearance, and proper fitment rather than chasing a wide range of original-era tire formats. This exact model uses a 245/40R18 radial tire on an 18-inch wheel. Within that size, choices include blackwall performance tires as well as redline and raised white letter options for a more customized look. The real decision is matching that 18-inch fitment to the car's current wheels, intended use, and preferred visual style.
Which Tire Size Is Right for The 2009 Lexus GS460
The 2009 Lexus GS460 uses one primary tire size: 245/40R18 radial on an 18-inch rim. The Base sub-model uses that same fitment, so the main decision is not which factory size applies, but which version of that size best suits the car's current wheel setup, driving use, and preferred sidewall style.
A 245/40R18 size identifies a metric radial tire with a 245-millimeter nominal section width, a 40-series profile, and fitment for an 18-inch wheel. On the 2009 Lexus GS460, that low-profile radial sizing supports the car's modern luxury-performance character and keeps tire selection focused on correct wheel compatibility rather than vintage sizing conversion. Available choices in this size include blackwall performance-oriented tires, plus redline and raised white letter alternatives in the Street Pro III series. This size is the right starting point when the car still uses the intended 18-inch wheel diameter and similar overall fitment.
Sub-model fitment is straightforward for the 2009 Lexus GS460. The covered Base model uses the same 245/40R18 radial size, so selection comes down to product type, sidewall appearance, and confirming the actual wheel setup on the car.

2009 Lexus GS460 Base
The 2009 Lexus GS460 Base uses the same 245/40R18 radial fitment as the core model. That keeps size selection simple and shifts attention toward wheel-width compatibility, intended street or specialty use, and whether a blackwall, redline, or raised white letter presentation better suits the car.
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.

Common questions for the 2009 Lexus GS460 usually center on its single 245/40R18 fitment, 18-inch wheel compatibility, sidewall style choices, and what to inspect before putting a modern performance sedan back into regular road use.
Tire Size & Fitment
What tire size fits a 2009 Lexus GS460?
The 2009 Lexus GS460 uses a 245/40R18 radial tire. That is the primary fitment for this model, and the covered Base sub-model uses the same size, which keeps the fitment question fairly straightforward compared with vehicles that vary by trim or wheel package.
The practical next step is confirming that the car still has 18-inch wheels in an appropriate width range for the tire being considered. Many GS sedans remain stock, but aftermarket wheels can change width and offset, so the correct size code alone is not the only thing worth checking before replacement.
What size rim does a 2009 Lexus GS460 use?
The 2009 Lexus GS460 uses an 18-inch rim with its 245/40R18 tire fitment. Product options in this size are built around that 18-inch wheel diameter, so the wheel itself must match before any tire in this size can be considered.
Rim diameter is only part of the fitment picture. Wheel width also matters, and the available 245/40R18 products show different width recommendations depending on the tire. A quick wheel inspection helps prevent choosing a tire that matches the diameter but does not suit the actual wheel width on the car.
Does the 2009 Lexus GS460 Base use the same tire size?
Yes. The 2009 Lexus GS460 Base uses the same 245/40R18 radial tire size as the core model. That means there is no separate sub-model size split to sort through before comparing tires for appearance, construction, or intended use.
Even with consistent sub-model sizing, the car's current setup still deserves a look before purchase. Replacement wheels, suspension changes, or staggered aftermarket combinations can affect what is on the vehicle now. Matching the tire to the wheel actually installed is more useful than relying on the badge alone.
Choosing the Right Tire
What should I consider when choosing a 245/40R18 tire for a 2009 Lexus GS460?
Start with the exact 245/40R18 size and confirm that the tire matches the car's 18-inch wheel diameter. From there, compare intended use, since the available choices include general performance street radials, a drag-oriented radial, and sidewall treatments that can change the car's look without changing the basic size.
Wheel width is one of the most important comparison points once the size is settled. Some 245/40R18 options show fitment around 8.0 to 9.5 inches, while another is built around an 8.5-inch rim. That makes it smart to verify the wheel first, then narrow the choice by appearance and use.
What sidewall styles are available for 2009 Lexus GS460 tires?
The available 245/40R18 tires for the 2009 Lexus GS460 include blackwall, redline, and RWL sidewall styles. Blackwall choices lean toward a more modern, understated presentation, while redline and raised white letter options bring a more customized visual character to the car.
Sidewall style does not change the need for correct size and wheel compatibility, but it can have a major effect on the finished look. A buyer trying to preserve the GS460's contemporary luxury-sport feel may prefer blackwall, while a more personalized build may lean toward redline or raised white letters.
What brands offer tires for the 2009 Lexus GS460?
245/40R18 tires for the 2009 Lexus GS460 are available from M&H Racemaster, BFGoodrich, Nitto, and Pro-Trac. Those brands cover several different tire series, including drag-oriented and street-focused radial options, rather than presenting one uniform type of replacement.
Brand choice is most useful when paired with the rest of the tire's character. Some options focus on performance street driving, some on specialty use, and some add visual distinction through sidewall styling. Comparing series, sidewall treatment, and wheel-width suitability will usually tell more than the brand name by itself.
Restoration & Appearance
Which tire should I choose for a period-style 2009 Lexus GS460?
A period-style approach for a 2009 Lexus GS460 usually starts by staying with the correct 245/40R18 low-profile radial format and an 18-inch wheel. Since this is a modern luxury-performance sedan rather than a bias-ply-era car, the strongest appearance decision is usually sidewall treatment rather than construction type.
Blackwall options tend to preserve the clean, contemporary look most buyers associate with this generation. Redline or raised white letter versions can create a more customized presentation while keeping the same basic size. If originality matters closely, compare the car's current appearance against marque-specific photos, brochures, or club references.
How does tire construction affect the appearance of a restored 2009 Lexus GS460?
For the 2009 Lexus GS460, construction is less about bias-ply-versus-radial history and more about preserving the proper modern stance and sidewall profile. This model uses a radial 245/40R18 fitment, so staying within that general construction and size format helps maintain the crisp, performance-oriented appearance expected of the car.
Appearance changes more noticeably through tread style and sidewall treatment than through construction changes on this application. A blackwall tire keeps the look restrained, while redline or raised white letter versions shift the car toward a more expressive custom style. Wheel diameter and sidewall profile should remain priorities for visual balance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2009 Lexus GS460?
Yes. A 2009 Lexus GS460 may have the correct factory-style 245/40R18 fitment on paper, but aftermarket wheels, lowered suspension, alignment changes, or body modifications can alter what works on the car in practice. Diameter, width, and wheel position all influence whether the tire suits the current setup.
Checking the actual wheel diameter and width is a good first step, followed by a look at fender and steering clearance. A tire that is appropriate for a stock configuration can still create issues on a modified car. That is especially important when replacing only one pair or matching an existing aftermarket setup.
What should I inspect before driving a 2009 Lexus GS460 on new tires?
Before road use, inspect wheel condition, confirm tire pressure, and make sure each tire seats properly on the rim. It also helps to look over the suspension and alignment condition, since uneven wear or vibration on a 2009 Lexus GS460 can come from the chassis as much as from the tire itself.
A short, careful test drive can reveal rubbing, pull, vibration, or unusual noise before the car is used normally. It is also worth checking lug torque, especially if the wheels have recently been removed or changed. Catching those details early helps the new 245/40R18 tires deliver the fitment they were chosen for.
How often should tires on a 2009 Lexus GS460 be inspected?
Tires on a 2009 Lexus GS460 should be inspected regularly, especially if the car is driven infrequently or stored for part of the year. Low-use vehicles can still develop pressure loss, cracking, flat spotting, or age-related sidewall concerns even when tread wear looks minimal.
A quick visual check before routine drives and a more thorough inspection before longer trips is a sensible pattern. Look for cuts, bulges, uneven wear, and signs of rubbing, then confirm pressure with a gauge rather than by appearance alone. Storage away from prolonged heat and sunlight also helps preserve tire condition.
