2022 Lexus IS300 Tires

A 2022 Lexus IS300 uses either 235/45R18 or 235/40R19, both in radial construction. The 235/45R18 size applies to standard AWD and RWD models, while the 235/40R19 size applies to AWD and RWD models equipped with the Premium Package.

The key step is confirming the exact sub-model and the wheel diameter currently on the car. Since this Lexus uses both 18-inch and 19-inch fitments, ordering by model name alone is not enough if the wheels have ever been changed or if the package level is unclear.

The 2022 Lexus IS300 uses either an 18-inch or 19-inch rim, depending on configuration. The 235/45R18 tire fits the 18-inch setup, and the 235/40R19 tire fits the 19-inch setup found on Premium Package versions.

Rim diameter should be verified before comparing tires because the two fitments are not interchangeable across wheel sizes. It also helps to confirm actual wheel width, especially if the car has aftermarket wheels, since product rim-width ranges matter when narrowing down the right tire choice.

No. Standard 2022 Lexus IS300 AWD and RWD models use 235/45R18, while AWD and RWD models with the Premium Package use 235/40R19. The difference is tied to the wheel package rather than simply to the driveline alone.

That means the exact sub-model matters before selecting a tire. A quick check of the vehicle's package, wheel diameter, and the size marking on the current tire will usually settle the question and prevent mixing up the standard 18-inch fitment with the 19-inch Premium Package setup.

Start with the correct size, then compare the available BFGoodrich radial options within 235/45R18. This fitment includes several g-Force series choices in Blackwall styling, with rim-width compatibility spanning typical sport-sedan wheel widths in the 18-inch range.

Beyond size, think about how the car is used and how closely the wheel setup matches the intended tire. Series differences, load specification, and wheel-width compatibility can all influence the decision, especially on a sedan that blends daily comfort with sharper handling expectations.

The currently available tires for the 2022 Lexus IS300 fitments are from BFGoodrich. In the 235/45R18 size, the lineup includes multiple g-Force series options, while the 235/40R19 fitment is available in BFGoodrich g-Force Phenom T/A form.

That makes the selection process more about choosing the right size, series, and wheel-width compatibility than comparing across several brands. Checking the installed wheel diameter first is still essential, since the 18-inch and 19-inch Lexus fitments lead to different product choices within the same brand family.

The 2022 Lexus IS300 fitments are available in BFGoodrich g-Force series tires, including g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. The broader series selection appears in 235/45R18, while 235/40R19 is available in g-Force Phenom T/A.

Series choice matters most after the correct size is confirmed. On the 18-inch fitment, there is more room to compare product character within the same overall size, while the 19-inch fitment narrows the field and makes wheel-width suitability an even more important part of the decision.

Yes. Even on a modern car like the 2022 Lexus IS300, staying with the correct tire size helps preserve the intended stance and the visual balance between wheel and sidewall. The 18-inch standard setup and 19-inch Premium Package setup create noticeably different presentations.

Appearance work should begin with confirming whether the car is meant to reflect the standard wheel package or the Premium Package look. Once that is settled, choosing the proper size and a clean Blackwall radial keeps the result cohesive without introducing avoidable fitment or proportion issues.

The two approved sizes give the 2022 Lexus IS300 different visual character. A 235/45R18 leaves a slightly fuller sidewall on an 18-inch wheel, while a 235/40R19 creates the shorter-profile look associated with the Premium Package wheel setup.

That appearance difference is one reason to confirm the intended configuration before replacing tires. Matching the car's actual wheel package helps maintain the proper proportions, and it also avoids the common mistake of selecting a tire that belongs to the other IS300 setup.

Yes. Wheel changes, suspension lowering, spacer use, or non-original offsets can all affect tire fitment on a 2022 Lexus IS300, even when the tire size itself looks close to stock. The car's two factory fitments already separate 18-inch and 19-inch setups.

Any modified IS300 should be checked for actual wheel diameter, wheel width, and clearance at the fender and suspension before a new tire is chosen. Looking at the current tire markings and measuring the wheel setup can prevent ordering a tire that suits the model but not the car's present configuration.

Before road use, inspect tire pressure, valve stems, wheel condition, and the basic mounting setup. It is also smart to look over tread seating, confirm there are no sidewall cuts or shipping damage, and make sure the tires match the wheel diameter and intended position on the car.

A short check of alignment behavior, steering feel, and clearance during low-speed turning is worthwhile after installation. On a sport sedan like the IS300, uneven suspension wear or an undiscovered wheel issue can affect how a new tire behaves long before the tread itself becomes a problem.

Tires on a 2022 Lexus IS300 should be inspected regularly, not just when tread looks low. Frequent checks for pressure loss, irregular wear, punctures, bulges, and sidewall damage help catch problems early, especially on lower-profile tires that can be more vulnerable to road impact issues.

Monthly visual checks are a good habit, along with a closer inspection before longer highway trips. Any vibration, pull, repeated air loss, or sudden wear pattern deserves attention quickly, since those signs can point to alignment, wheel, or suspension concerns rather than a tire problem alone.
