2024 Lexus IS300 Tires

The 2024 Lexus IS300 uses three primary tire sizes: 235/45R18, 235/40R19, and 265/35R19. The correct size depends on the exact configuration, with standard AWD and RWD models using 235/45R18, several Premium Package and F Sport-related applications using 235/40R19, and the F Sport rear position using 265/35R19.

That means the first step is identifying the car’s actual sub-model and wheel setup before ordering replacements. An 18-inch IS300 and a 19-inch IS300 do not use the same tire, and the staggered F Sport arrangement adds a separate rear size that should be checked carefully against the front fitment already on the car.

The 2024 Lexus IS300 uses either an 18-inch or 19-inch rim, depending on the version of the car. The 235/45R18 fitment uses an 18-inch wheel, while both 235/40R19 and 265/35R19 are 19-inch applications found on Premium Package and F Sport-related setups.

Rim diameter should be confirmed before looking at tread pattern or brand, because the tire must match the wheel diameter exactly. It also helps to verify actual wheel width when comparing products, especially on 19-inch applications where a front size and a wider rear size may be part of a staggered package.

No, 2024 Lexus IS300 sub-models do not all use the same tire size. Standard AWD and RWD versions use 235/45R18, Premium Package and several F Sport-related versions use 235/40R19, and the F Sport rear application uses a separate 265/35R19 size.

That variation matters because the correct replacement depends on more than the model name alone. Checking the door placard, reading the size on the current tires, and confirming whether the car has a square or staggered wheel setup will help prevent mixing an 18-inch standard fitment with a 19-inch package tire.

Start with the correct size for the exact 2024 Lexus IS300 configuration, then compare tire series, construction details, and wheel-compatibility specifications within that size. This model uses only radial primary fitments, but the choices still vary by 18-inch versus 19-inch application and, on some versions, by front versus rear position.

Once the size is confirmed, compare practical details such as rim-width range, load figures where stated, and how the tire will be used. A daily-driven IS300 with standard wheels may call for a different product emphasis than an F Sport with staggered 19-inch fitment, even though both remain within the correct factory-style size family.

The available tire choices for the 2024 Lexus IS300 come from BFGoodrich and Nitto, depending on size. BFGoodrich appears across all three fitments, while Nitto is present in the 265/35R19 rear application used on the F Sport staggered setup.

Brand is only one part of the decision, so it helps to compare which series each brand offers in the exact size needed. For example, a standard 235/45R18 application stays within BFGoodrich choices, while the wider 265/35R19 rear fitment opens an additional comparison point in Nitto alongside BFGoodrich offerings.

Available 2024 Lexus IS300 tire series include BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2. The exact series depends on the tire size, so not every IS300 configuration has access to every series shown across the model range.

That makes it important to narrow the search by size first and only then compare series. Once the correct fitment is established, differences such as rim-width range, load specification, and the intended use of the car can help separate a suitable replacement tire from one that simply shares the same basic diameter.

Yes, correct tire fitment still matters on a 2024 Lexus IS300, especially when the goal is to preserve the car’s intended stance and wheel-to-tire balance. This model uses specific 18-inch and 19-inch radial sizes, and the F Sport arrangement adds a wider rear fitment that plays a visible role in how the car sits.

Appearance builds can go off course quickly if wheel diameter or staggered sizing is ignored. Matching the proper front and rear sizes, keeping the right profile family, and confirming that aftermarket wheels have not changed the original fitment logic will do more for the finished look than choosing a tire by brand name alone.

The available 2024 Lexus IS300 tire options use a blackwall sidewall style, which suits the clean, modern sport-sedan appearance of the model. There are no alternate whitewall or stripe-style sidewall treatments in the current fitments, so the visual choice is more about tire series and overall stance than contrasting sidewall design.

For a stock-look presentation, staying with the correct size and wheel diameter usually matters more than chasing extra styling cues. On this Lexus, a properly matched blackwall tire in the right 18-inch or 19-inch fitment keeps the appearance cohesive, particularly when the car uses a staggered F Sport setup with different front and rear sizes.

Yes, modifications can affect tire fitment on a 2024 Lexus IS300 even when the tire size seems close to stock. Wheel changes, altered wheel width, different offsets, suspension lowering, or changes to the car’s front-to-rear setup can all influence whether the original 235/45R18, 235/40R19, or 265/35R19 fitment logic still applies.

A modified IS300 should be checked at the wheel itself, not just by trim name. Confirming actual wheel diameter, measuring clearance at full steering lock, and noting whether the car still uses a square or staggered arrangement will help avoid choosing a tire that matches the badge but not the vehicle’s present-day setup.

Before driving a 2024 Lexus IS300 on new tires, inspect the wheel condition, confirm the tire size matches the correct axle position, and make sure inflation is set appropriately for the installation. It also helps to verify that the tires seat properly on the wheels and that there is no interference at the fender, suspension, or steering components.

A short initial check after installation is worthwhile, especially on 19-inch and staggered setups. Recheck air pressure, listen for rubbing during low-speed turns, and look for any sign of uneven seating or contact marks. Catching a wheel or clearance issue early is much easier than discovering it after several hundred miles of road use.

Tires on a 2024 Lexus IS300 should be inspected regularly, not only when tread wear becomes obvious. A visual check for cuts, bulges, punctures, uneven wear, and pressure loss is a good habit on any modern sport sedan, particularly one that may use lower-profile 19-inch tires or a wider rear staggered fitment.

Routine inspection becomes even more important if the car is driven spiritedly, parked for long periods, or has aftermarket wheels. Looking at both front and rear tires separately, checking pressures when the tires are cold, and watching for changes in ride feel or steering response can help catch fitment or wear issues before they grow into a larger problem.
