The 2024 Lexus IS350 sits in the modern sport sedan space with a strong emphasis on sharp handling, rear-drive balance, and an assertive F Sport presentation. On this car, tire selection is closely tied to that performance character because the fitment uses a staggered 19-inch radial setup: 235/40R19 in front and 265/35R19 in the rear. That means the real decision is less about choosing one universal size and more about matching the correct front and rear positions while comparing the available product choices within each size. For owners focused on confident road manners, appearance, and proper fitment, confirming the exact axle position is the first step.
Which Tire Size Is Right for The 2024 Lexus IS350
The 2024 Lexus IS350 uses two primary tire sizes, both built as radial tires on 19-inch rims. These sizes are position-specific rather than interchangeable, so the first step is confirming whether you are replacing the front or rear tires on an F Sport Design or F Sport setup before comparing products, load specifications, or rim-width compatibility.
235/40R19 is a modern metric radial size in which 235 identifies the nominal section width in millimeters, 40 is the aspect ratio, R designates radial construction, and 19 is the rim diameter in inches. On the 2024 Lexus IS350, this size is used in the front position on the covered F Sport Design and F Sport configurations. Available choices in this size include BFGoodrich with a Blackwall sidewall and the g-Force Phenom T/A series. This size should be evaluated as a front-axle fitment, with attention to wheel width, load capacity, and maintaining the intended staggered setup.
265/35R19 is a modern metric radial size where 265 indicates nominal section width in millimeters, 35 is the aspect ratio, R means radial construction, and 19 identifies the rim diameter in inches. On the 2024 Lexus IS350, this size is used in the rear position for the covered F Sport Design and F Sport applications. Rear tire choices include Blackwall options from BFGoodrich and Nitto across series such as g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. This is the size to review when replacing rear tires and confirming wheel-width compatibility on the wider rear fitment.
Sub-model fitment on the 2024 Lexus IS350 is straightforward in one sense and position-specific in another. The covered F Sport Design and F Sport applications share the same staggered arrangement, so the key is identifying whether the tire is for the front or rear axle before making a selection.

2024 Lexus IS350 F Sport Design Front
The 2024 Lexus IS350 F Sport Design Front uses the narrower front radial size on a 19-inch rim. Tire selection here centers on preserving the intended front fitment while comparing available Blackwall product options and wheel-width compatibility.
The 2024 Lexus IS350 F Sport Design Rear uses the wider rear radial size on a 19-inch rim. That makes rear-tire selection more about choosing among the available series and brands while keeping the staggered front-to-rear relationship intact.
The 2024 Lexus IS350 F Sport Front uses the same front radial size as the F Sport Design Front. For replacement, the practical focus is matching the correct front size and checking wheel-width suitability rather than treating the tire as interchangeable with the rear.
The 2024 Lexus IS350 F Sport Rear uses the same wider rear radial size as the F Sport Design Rear. Choosing a rear tire means staying with the correct rear specification and comparing the available Blackwall performance-oriented product lines in that size.
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.
Best 2024 Lexus IS350 Tires for Sale
Available 2024 Lexus IS350 tire choices focus on 19-inch radial Blackwall performance tires.

Tire questions for the 2024 Lexus IS350 usually come down to front-versus-rear sizing, 19-inch rim fitment, product selection within each radial size, and the checks that matter before putting a staggered sport sedan back on the road.
Tire Size & Fitment
What tire size fits a 2024 Lexus IS350?
The 2024 Lexus IS350 uses a staggered tire setup with 235/40R19 in the front and 265/35R19 in the rear. Both are radial tires mounted on 19-inch rims, and the covered F Sport Design and F Sport applications follow that same front-to-rear sizing pattern.
That means there is not one single tire size for every position on the car. Replacing tires starts with confirming axle location, then matching the wheel width and tire specifications to the correct front or rear size so the staggered setup, clearance, and handling balance remain consistent.
What size rim does a 2024 Lexus IS350 use?
The 2024 Lexus IS350 tire fitments covered here use 19-inch rims at both the front and rear. The front tire size is 235/40R19 and the rear is 265/35R19, so both tire sizes share the same rim diameter even though their widths and profiles differ.
Rim diameter is only part of the fitment picture on a staggered setup. Wheel width still matters, especially when moving between the narrower front size and the wider rear size, so it is important to confirm the actual wheel dimensions on the car before selecting replacement tires.
Do all 2024 Lexus IS350 sub-models use the same tire size?
The covered 2024 Lexus IS350 F Sport Design and F Sport applications use the same staggered pattern rather than one universal size. Both use 235/40R19 on the front and 265/35R19 on the rear, so the fitment is shared by axle position across those sub-model entries.
That consistency makes product selection easier, but only if front and rear positions are kept separate. A buyer still needs to verify which axle needs replacement and check the wheel setup on the car, especially if wheels or suspension have been changed from the original configuration.
Choosing the Right Tire
What should I consider when choosing a 2024 Lexus IS350 tire?
Start with the correct axle-specific size: 235/40R19 for the front and 265/35R19 for the rear. From there, compare radial construction details such as rim-width compatibility, load specification where stated, tire series, and the role each tire will serve in a staggered sport sedan setup.
A good choice depends on matching the tire to the actual wheel and intended use of the car. Owners replacing one pair should pay special attention to maintaining front-to-rear fitment balance, while those replacing all four can compare the available series and brand options with a clearer view of the full setup.
What sidewall styles are available for 2024 Lexus IS350 tires?
The available 2024 Lexus IS350 tire options in these sizes use a Blackwall sidewall style. That applies to the front 235/40R19 fitment and to the rear 265/35R19 choices, keeping the appearance aligned with the modern performance-sedan look of the IS350.
Since sidewall treatment does not vary here, the more meaningful comparisons are tire series, brand, wheel-width compatibility, and other construction details. For most buyers, the decision is less about appearance differences and more about selecting the right performance-oriented radial within the correct front or rear size.
What brands offer tires for the 2024 Lexus IS350?
BFGoodrich and Nitto offer tire choices for the covered 2024 Lexus IS350 fitments. BFGoodrich appears in both sizes, while Nitto is available in the 265/35R19 rear fitment, giving the rear position a broader brand comparison than the front.
Brand alone should not drive the decision on a staggered setup. It helps more to compare the exact size, tire series, wheel-width suitability, and any stated load details so the tire matches the front or rear role on the car instead of treating all 19-inch options as interchangeable.
Restoration & Appearance
Which tire should I choose for a period-style 2024 Lexus IS350?
A period-style question applies differently to a modern sport sedan like the 2024 Lexus IS350 than it would to a vintage collector car. The closest match to the car's intended presentation is staying with the correct staggered radial sizes, 235/40R19 front and 265/35R19 rear, in the available Blackwall format.
Appearance on this Lexus is shaped more by proportion and axle-specific fitment than by vintage sidewall treatments. Keeping the correct front and rear sizes preserves the visual balance of the setup, while product selection can then focus on tire series, wheel-width compatibility, and the kind of road use the car will see.
Does correct tire fitment matter for a 2024 Lexus IS350 restoration or appearance refresh?
Correct tire fitment matters because the 2024 Lexus IS350 uses a staggered arrangement that affects both stance and proportion. Using the proper 235/40R19 front and 265/35R19 rear sizes keeps the car visually balanced and avoids the mismatched look that can come from treating both axles the same.
An appearance refresh should begin with confirming the actual wheels on the car, especially if it was previously modified. Once the wheel setup is verified, comparing Blackwall radial choices by series and fitment details will do more for the final look than forcing a tire intended for the opposite axle.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2024 Lexus IS350?
Yes, modifications can affect tire fitment on a 2024 Lexus IS350 even when the nominal tire sizes remain 235/40R19 front and 265/35R19 rear. Aftermarket wheels, altered wheel widths, suspension changes, or ride-height changes can all influence how those tires sit and clear the body and suspension.
A car with changes from stock should be checked more carefully before replacement tires are chosen. Confirm the actual wheel dimensions, inspect steering and fender clearance, and make sure the front and rear tires are still being matched to the correct axle positions rather than relying on size alone.
What should I inspect before driving a 2024 Lexus IS350 on new tires?
Before driving a 2024 Lexus IS350 on new tires, inspect tire pressure, wheel condition, lug torque, and basic clearance at both the front and rear. It also helps to confirm that the correct staggered sizes were installed in the proper positions and that there is no contact at full steering lock.
A short road test should include attention to vibration, pull, or unusual noise that could point to a mounting, balance, or fitment issue. After the first miles, recheck pressures and give the tires another visual inspection so any early problem is caught before the car is driven harder or farther.
What should I check before a longer drive in a 2024 Lexus IS350?
Before a longer drive, check that the 2024 Lexus IS350 has the correct 235/40R19 front and 265/35R19 rear tires installed, with pressures set appropriately for the tires on the car. Tread condition, cuts, bulges, and any signs of air loss should be reviewed before heading out.
Longer trips also make wheel and suspension condition more important, especially on a performance-oriented sedan with a staggered setup. A quick look at alignment wear, brake clearance, and any rubbing marks around the inner fenders can help prevent a small fitment issue from becoming a roadside problem.
