The 2014 Lexus IS F belongs to a late chapter in the high-performance sport sedan era, blending Lexus refinement with a serious factory performance focus. Buyers looking at one today are often balancing spirited road use with the need to preserve the car’s sharp, original stance. Tire fitment centers on a staggered radial setup, with 225/40R19 at the front and 255/35R19 at the rear, both on 19-inch rims. That means the decision is less about choosing among several factory sizes and more about matching the correct front and rear fitment while comparing available BFGoodrich g-Force series options. Wheel setup, tire profile, and front-to-rear placement all matter before selection.
Which Tire Size Is Right for The 2014 Lexus IS F
The 2014 Lexus IS F uses two primary tire sizes, and they are position-specific rather than interchangeable. 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 has its staggered wheel setup, since proper tire selection depends on keeping the front and rear sizes in their correct positions.
225/40R19 is a modern metric radial size. In plain terms, 225 identifies the tire’s nominal section width in millimeters, 40 is the aspect ratio, R confirms radial construction, and 19 is the wheel diameter in inches. On the 2014 Lexus IS F, this size serves the front position and helps preserve the intended staggered setup. Available choices center on BFGoodrich blackwall performance tires in the g-Force Comp 2 AS and g-Force Phenom T/A series. Selecting this size starts with confirming front wheel width and keeping it matched to the car’s front axle position.
255/35R19 is also a modern metric radial size, but it is wider and lower in profile than the front tire. The 255 width is given in millimeters, 35 is the aspect ratio, R denotes radial construction, and 19 identifies the wheel diameter in inches. On the 2014 Lexus IS F, this size belongs on the rear and is part of the car’s staggered fitment. BFGoodrich offers blackwall options here across the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A lines. Rear tire selection should account for the correct wheel width and the need to maintain front-to-rear balance.
Fitment on the 2014 Lexus IS F is straightforward once the tire position is identified, because the front and rear use different sizes. Checking whether you are replacing a front tire or a rear tire matters more than trim differences here, since the car uses a staggered setup.

Tire Size & Fitment
What tire size fits a 2014 Lexus IS F?
The 2014 Lexus IS F uses a staggered tire setup with 225/40R19 at the front and 255/35R19 at the rear. Both are radial tires designed for 19-inch wheels, and the two sizes serve different positions on the car rather than acting as interchangeable replacements.
That means the first step is identifying whether you need a front tire or a rear tire. It is also worth confirming that the car still has its original-style staggered wheel arrangement, because aftermarket wheels or previous tire changes can alter what size belongs at each end.
What size rim does a 2014 Lexus IS F use?
The 2014 Lexus IS F uses 19-inch rims with both of its primary tire sizes. The front 225/40R19 and rear 255/35R19 sizes share the same wheel diameter, but they are matched to different wheel widths because the car uses a staggered performance layout.
Wheel diameter is only part of the fitment picture on this Lexus. Before choosing tires, confirm whether the wheels are the original 19-inch setup or an aftermarket replacement, then compare the wheel width to the tire’s approved range so the front and rear sizes stay matched to the correct positions.
Why does the 2014 Lexus IS F have more than one tire size?
The 2014 Lexus IS F has more than one tire size because it uses a staggered setup, with one size for the front axle and a wider size for the rear. In this case, 225/40R19 is used in front and 255/35R19 is used in back, both in radial construction.
A staggered arrangement means tire replacement is position-specific. Mixing up the sizes or assuming the front and rear are interchangeable can create fitment problems, so it helps to verify wheel placement, check the actual wheel widths on the car, and replace tires in a way that preserves the intended front-to-rear setup.
Choosing the Right Tire
What should I consider when choosing a 225/40R19 and 255/35R19 tire for a 2014 Lexus IS F?
Start with the basics: the 2014 Lexus IS F needs 225/40R19 in front and 255/35R19 in the rear, both on 19-inch wheels. From there, compare radial tire series, approved rim-width ranges, load figures where stated, and the intended role of the tire within the car’s staggered setup.
A buyer choosing tires for this Lexus is usually balancing handling character, wheel compatibility, and consistent appearance from front to rear. It helps to confirm the wheel dimensions on the car, decide whether the goal is everyday road use or more aggressive driving, and then compare each front and rear option as a matched pair.
What brands offer tires for the 2014 Lexus IS F?
Current fitment options for the 2014 Lexus IS F are available from BFGoodrich in both front and rear sizes. The available products cover multiple g-Force series, giving the car owner more than one way to stay within the correct staggered 19-inch radial fitment.
Since the brand choice is concentrated within one manufacturer, the real comparison becomes series, rim-width compatibility, and specification details rather than brand-versus-brand shopping. It is worth reviewing the front and rear products together so the selected pair supports the same use, appearance, and wheel setup across the whole car.
What tire series are available for the 2014 Lexus IS F?
The 2014 Lexus IS F is offered in BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A tire series, depending on size. The front 225/40R19 fitment is available in g-Force Comp 2 AS and g-Force Phenom T/A, while the rear 255/35R19 adds g-Force Sport Comp 2 to the mix.
Series choice matters because it affects how you compare the front and rear tires as a coordinated set. Matching the correct size to each axle comes first, then the buyer can look at specification details such as rim-width range, weight, and load information where shown to decide which combination best suits the car’s intended use.
Restoration & Appearance
Does correct tire fitment matter for a 2014 Lexus IS F restoration?
Yes, correct tire fitment matters on a 2014 Lexus IS F even though it is a newer performance-era collector car rather than a traditional vintage restoration candidate. The car uses a staggered 19-inch setup, so keeping 225/40R19 in front and 255/35R19 in the rear helps preserve its intended stance and overall presentation.
Appearance on an IS F is tied closely to proportion and wheel-to-tire balance. A restoration-minded owner should confirm the actual wheels on the car, avoid treating front and rear sizes as interchangeable, and choose tires that maintain the correct visual relationship between the narrower front and wider rear fitment.
How does tire construction affect the appearance of a restored 2014 Lexus IS F?
On the 2014 Lexus IS F, construction does not create a bias-ply versus radial appearance decision because the primary fitment is already radial. The more noticeable appearance factors are the correct staggered sizing, the low-profile shape of each tire, and the consistent blackwall presentation across the available choices.
That makes the visual goal less about changing construction and more about preserving the car’s factory-era performance look. Owners aiming for a clean, restoration-oriented result should keep the front and rear sizes in their proper positions and compare tire series carefully so the completed setup looks balanced on all four corners.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2014 Lexus IS F?
Yes, modifications can affect tire fitment on a 2014 Lexus IS F even when the nominal tire sizes remain 225/40R19 front and 255/35R19 rear. Aftermarket wheels, suspension changes, altered ride height, or body modifications can change the wheel width, offset, and available clearance around the tire.
That is why a modified IS F should be checked as it sits rather than assumed to match stock dimensions. Confirm wheel diameter and width, inspect clearance at full steering lock and suspension travel, and make sure the front and rear tires still suit the car’s staggered layout before finalizing a replacement set.
What should I inspect before driving a 2014 Lexus IS F on new tires?
Before driving a 2014 Lexus IS F on new tires, inspect the wheel condition, verify that the correct front and rear sizes were installed, and check inflation pressure. It also helps to look over the suspension and alignment condition, since a performance sedan with a staggered setup can be sensitive to uneven wear or setup issues.
A short road check should include listening for rubbing, confirming stable steering response, and making sure there is no contact at parking-lot speeds or over moderate suspension movement. Rechecking pressure after initial use is smart, especially on a car that may sit for periods between drives or seasonal use.
How should tires on a 2014 Lexus IS F be maintained?
Tires on a 2014 Lexus IS F should be maintained with regular pressure checks, visual inspection for cuts or sidewall damage, and tread monitoring across both the front 225/40R19 and rear 255/35R19 sizes. Because the car uses a staggered setup, front-to-rear rotation may not be possible in the conventional sense.
Collector or low-use examples deserve extra attention because tire age and storage conditions can matter as much as tread depth. Keeping the car away from prolonged sunlight, moisture, and ozone sources helps, and periodic inspection for cracking, bulges, or slow air loss is worthwhile before any longer drive.
