The 2009 Lexus IS F marked a serious turn in Lexus performance, blending compact sport-sedan proportions with the sharper character expected from a purpose-built V8 flagship. That mix of luxury and high-speed intent makes tire selection more than a routine maintenance item. This car uses a staggered radial setup with 225/40R19 up front and 255/35R19 at the rear, both on 19-inch rims. Available choices stay within a modern blackwall performance theme and vary by tire series, rim-width compatibility, load specification, and overall character. For an IS F owner, the real priority is preserving the intended front-to-rear balance while confirming the car still has the correct wheel setup.
Which Tire Size Is Right for The 2009 Lexus IS F
The 2009 Lexus IS F uses two primary tire sizes, and they are tied to position rather than trim variation. Both are radial tires on 19-inch rims, with 225/40R19 used at the front and 255/35R19 at the rear. The first step is confirming that the car still retains its staggered 19-inch wheel setup, since choosing the right tire depends on matching the correct size to the correct axle.
225/40R19 is a metric radial size in which 225 identifies the nominal section width in millimeters, 40 is the aspect ratio, R denotes radial construction, and 19 is the wheel diameter in inches. On the 2009 Lexus IS F, this size serves the front position and helps preserve the intended staggered fitment. Available choices center on BFGoodrich blackwall performance tires, including g-Force Comp 2 AS and g-Force Phenom T/A series. This is the size to evaluate when replacing front tires and when checking that steering response and front-end clearance remain consistent with the car's wheel setup.
255/35R19 is a metric radial size with a 255-millimeter nominal section width, a 35-series profile, radial construction, and a 19-inch rim diameter. On the 2009 Lexus IS F, this is the rear tire size in the factory-style staggered arrangement, giving the back of the car a wider footprint than the front. BFGoodrich options in this size include blackwall choices from the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A lines. It is the key size to review when replacing rear tires and when confirming that wheel width and rear clearance still match the intended setup.
Fitment on the 2009 Lexus IS F is straightforward in trim name but position-specific in practice. The Base Front and Base Rear use different tire sizes, so selecting the right tire means confirming whether the replacement is for the front axle or the rear axle.

2009 Lexus IS F Base Front
The 2009 Lexus IS F Base Front uses the narrower of the two staggered radial sizes on a 19-inch rim. That makes front-tire selection more about preserving the intended front fitment, steering feel, and wheel compatibility than simply matching the rear size for convenience.
The 2009 Lexus IS F Base Rear uses the wider 19-inch radial size in the staggered arrangement. Rear-tire selection should focus on matching the correct axle-specific size and confirming that the wheel width and clearance still suit the car if any wheel or suspension changes have been made.
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 2009 Lexus IS F tires focus on the staggered 19-inch radial setup, with BFGoodrich choices across the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. The main comparison points are front versus rear size, blackwall presentation, and rim-width and load specifications within each axle position.
These 2009 Lexus IS F tire FAQs focus on the staggered front and rear sizes, 19-inch rim fitment, product differences within each axle position, and the checks that matter before road use or after wheel and suspension changes.
Tire Size & Fitment
What tire size fits a 2009 Lexus IS F?
The 2009 Lexus IS F uses a staggered tire setup rather than one size at all four corners. The front tire size is 225/40R19, and the rear tire size is 255/35R19. Both are radial tires designed for 19-inch rims, so the car's fitment depends on keeping each size in its proper front or rear position.
That means tire replacement starts with confirming which axle needs tires, not just the model year and nameplate. A car that has been fitted with aftermarket wheels, different offsets, or non-original suspension height should also be checked carefully, because the correct size on paper still needs to match the actual wheel width and available clearance on the vehicle.
What size rim does a 2009 Lexus IS F use?
The 2009 Lexus IS F uses 19-inch rims with both of its primary tire sizes. The front 225/40R19 and rear 255/35R19 both share the same 19-inch rim diameter, even though the rear tire is wider and uses a lower aspect ratio than the front.
Rim diameter is only one part of the fitment picture, so it is worth checking wheel width as well before choosing replacement tires. Available front tires suit narrower rim-width ranges than the rear, and that matters on a staggered-performance car. Verifying both wheel diameter and wheel width helps prevent mismatches that can affect tire seating, handling balance, and clearance.
Why does the 2009 Lexus IS F have more than one tire size?
The 2009 Lexus IS F has more than one tire size because it uses a staggered setup, with one size at the front and a wider size at the rear. The front uses 225/40R19, while the rear uses 255/35R19. This is a position-based fitment arrangement, not a case of multiple trim levels sharing the same page.
For tire replacement, the practical takeaway is that front and rear tires should be selected by axle position rather than by choosing whichever size seems closest. Mixing up the sizes can upset the intended balance of the car. Anyone buying a used IS F should also confirm that the wheels have not been changed to a square setup before ordering tires.
Choosing the Right Tire
What should I consider when choosing a 2009 Lexus IS F tire?
Start with the basic fitment: 225/40R19 belongs on the front and 255/35R19 belongs on the rear of the 2009 Lexus IS F. From there, compare radial tire series, rim-width compatibility, load specifications where stated, and whether the tire is meant more for all-season use or a stronger performance-oriented character within the available lineup.
Selection also depends on how the car is used. A regularly driven IS F may call for different priorities than a fair-weather performance sedan with limited annual mileage. Matching the tire to the correct axle matters just as much as choosing the right series, especially on a staggered setup where front and rear tires are designed around different wheel widths.
What brands offer tires for the 2009 Lexus IS F?
Current 2009 Lexus IS F tire options in these fitment sizes center on BFGoodrich. Across the two primary sizes, BFGoodrich offerings include the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A lines, all in radial construction and blackwall form for the 19-inch staggered setup.
Since the available brand choice is concentrated, the buying decision shifts to comparing series within BFGoodrich rather than cross-shopping several manufacturers in the same exact fitment. It helps to look at the intended axle position first, then compare details such as rim-width range, load specification where stated, and the overall use you have in mind for the car.
What tire series are available for the 2009 Lexus IS F?
The 2009 Lexus IS F is covered by several BFGoodrich tire series in its staggered sizes. Depending on front or rear fitment, the available series include g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. Each remains a blackwall radial choice built around the car's 19-inch wheel diameter.
That variety gives an IS F owner room to compare tire character within the correct size instead of settling for a one-option replacement. The most useful approach is to keep the front and rear sizes matched to their intended axle positions, then compare the available series based on how the car is driven and whether wheel-width compatibility aligns with the wheels currently on the car.
Restoration & Appearance
Which tire should I choose for a period-style 2009 Lexus IS F?
A period-style 2009 Lexus IS F tire choice starts with preserving the original staggered format: 225/40R19 in front and 255/35R19 in the rear. Since the available products are modern radial blackwall performance tires, the appearance stays in line with the car's late-2000s sport-sedan character rather than shifting toward a vintage or retro presentation.
For an owner who wants the car to look appropriate to its era, the key is less about decorative sidewall treatment and more about keeping the correct front-to-rear proportions. Wheel changes can alter that look quickly, even if the tires themselves are quality replacements. Matching the intended axle sizes helps preserve the stance and visual balance associated with the IS F.
Does correct tire fitment matter for a 2009 Lexus IS F restoration?
Correct tire fitment matters on a 2009 Lexus IS F restoration because the car relies on a staggered 19-inch arrangement rather than a one-size setup. Keeping 225/40R19 at the front and 255/35R19 at the rear supports the visual stance and fitment logic associated with the model's original performance-oriented layout.
A restoration-minded owner should also look at the actual wheels on the car before ordering tires, especially if the vehicle has passed through multiple owners. Non-original wheel widths or offsets can change what works safely and what looks right. Even on a newer collector model, proper size and wheel compatibility are central to an authentic overall presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2009 Lexus IS F?
Yes, modifications can affect tire fitment on a 2009 Lexus IS F even when the correct factory-style tire sizes are known. Aftermarket wheels, altered offsets, suspension lowering, alignment changes, or body modifications can all influence whether 225/40R19 front and 255/35R19 rear tires have the clearance and wheel support they need.
That is why the actual car should be checked before replacement tires are chosen purely by catalog size. A staggered setup leaves less room for casual substitutions than a simple square arrangement. Looking at wheel width, tire-to-fender clearance, and steering lock clearance can prevent problems that only show up after installation and road use.
What should I inspect before driving a 2009 Lexus IS F on new tires?
Before driving a 2009 Lexus IS F on new tires, confirm that the front and rear sizes were installed in the correct positions and that inflation pressure is appropriate for the tire and vehicle setup. It is also smart to inspect wheel condition, valve stems, tread seating, and any visible signs of rubbing or uneven clearance around the suspension and fenders.
A short, careful road test is worthwhile after installation, especially on a staggered car with low-profile 19-inch tires. Pay attention to vibration, pulling, unusual noise, or contact under steering and suspension movement. Rechecking torque, pressure, and visual clearance after the first drive helps catch fitment issues early before they become wear or handling problems.
How should 2009 Lexus IS F tires be maintained?
Tires on a 2009 Lexus IS F should be maintained with regular pressure checks, visual inspections for cuts or sidewall damage, and close attention to tread wear across each axle. Because the car uses different front and rear sizes, maintenance also includes tracking wear patterns separately rather than assuming both ends of the car will age at the same rate.
Storage and usage patterns matter too, especially on a performance sedan that may see long periods of limited driving. Tires should be kept away from prolonged sunlight, moisture, and ozone sources whenever possible, and they should be inspected for aging before extended road use. Any persistent air loss, cracking, or bulging deserves immediate attention from a qualified tire professional.
