2019 Lexus LS500 Tires

The 2019 Lexus LS500 uses three primary tire sizes: 245/50R19, 245/45R20, and 275/40R20. Base models use either 245/50R19 or 245/45R20 depending on wheel package, while the LS500 F Sport uses a staggered setup with 245/45R20 in front and 275/40R20 in the rear.

The practical step is to confirm the exact sub-model and wheel diameter already on the car before ordering tires. A Base model on 19-inch wheels does not use the same fitment as an F Sport rear position, and the staggered F Sport arrangement means front and rear sizes serve different positions on the vehicle.

The 2019 Lexus LS500 uses either a 19-inch or 20-inch rim, depending on configuration. The 245/50R19 tire fits a 19-inch rim, while both 245/45R20 and 275/40R20 fit 20-inch rims. The F Sport setup uses 20-inch wheels front and rear, but with different tire widths.

Rim diameter should be confirmed before anything else because it determines which tire size family even belongs on the car. It also helps to verify actual wheel width, especially on 20-inch applications, since the available products can have different approved rim-width ranges within the same nominal tire size.

The 2019 Lexus LS500 has more than one tire size because fitment changes with wheel package and sub-model. Base models may use either a 19-inch or 20-inch tire size, while the F Sport uses a staggered arrangement with 245/45R20 in front and a wider 275/40R20 at the rear.

That means the correct tire choice is tied to the vehicle's exact configuration rather than the model name alone. A quick check of the current wheel diameter and whether the car is a Base or F Sport version prevents ordering a tire that is correct for an LS500 in general but wrong for that specific setup.

Start with the exact size the car uses, then compare construction, rim-width compatibility, sidewall style, and tire series within that fitment. On the 2019 Lexus LS500, all primary options are radial, so the decision usually comes down to matching the correct 19-inch or 20-inch size and selecting the tire character that best suits the car.

A Base model on 245/50R19 has a different shopping path than an F Sport rear on 275/40R20. Looking at load figures where available, wheel-width range, and whether the goal is a blackwall performance look or a more distinctive redline or raised white letter presentation helps narrow the field without drifting from the proper fitment.

Sidewall style depends on the tire size. Blackwall options are available across all three LS500 sizes, while redline and RWL choices appear in the 20-inch fitments, including 245/45R20 and 275/40R20. Those appearance-focused options come through the Pro-Trac Street Pro III series.

That gives 20-inch LS500 owners more visible styling variation, while 19-inch applications stay centered on blackwall tires. The best way to use that information is to confirm the car's actual wheel package first, then decide whether the tire should blend into a modern luxury-sedan look or add a more custom visual accent.

Tires for the 2019 Lexus LS500 are available from BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster, depending on size. BFGoodrich appears across all three fitments, Nitto covers both 20-inch sizes, Pro-Trac offers appearance-oriented 20-inch options, and M&H Racemaster appears in the 275/40R20 rear size.

Brand selection should still follow size and intended use first. A buyer comparing tires for a Base model on 245/50R19 will see a different mix than someone shopping for the F Sport rear, so it helps to treat the brand list as size-specific rather than assuming every brand offers the same choices across the whole LS500 range.

A period-style approach on a 2019 Lexus LS500 starts with keeping the exact tire size that belongs on the car's original wheel package. Since this is a modern luxury sedan with radial fitment only, the closest visual choice usually comes down to whether the owner wants a more understated blackwall presentation or a more custom look on the 20-inch applications.

For a factory-inspired appearance, staying close to the wheel diameter and overall visual character already on the car is usually the safest path. Redline and RWL options can create a stronger styling statement, but anyone chasing exact original delivery appearance should compare against vehicle-specific photos, window-sticker history, or marque references before deciding.

Tire construction is straightforward on the 2019 Lexus LS500 because the primary fitments are all radial. That means the visual difference is less about bias-ply versus radial shape and more about sidewall treatment, brand styling, and whether the car wears a 19-inch blackwall setup or one of the 20-inch combinations with redline or RWL availability.

Appearance changes can still alter how the car reads overall, especially on an F Sport with wider rear tires. Keeping the correct front and rear sizes in place preserves the intended stance, while sidewall style becomes the main cosmetic variable once the wheel diameter and staggered or non-staggered layout have been confirmed.

Yes, modifications can affect tire fitment on a 2019 Lexus LS500 even when the nominal tire size looks correct. Aftermarket wheels, changes in wheel width, offset differences, suspension lowering, or body and fender changes can all influence whether a 245/50R19, 245/45R20, or 275/40R20 setup still has proper clearance.

That matters most on the F Sport because the car uses different front and rear sizes, and the wider rear tire leaves less room for guesswork. Before changing tires, check the wheel dimensions actually on the car and inspect steering and suspension clearance through the full range of movement rather than relying on size code alone.

Before driving a 2019 Lexus LS500 on new tires, inspect tire pressure, bead seating, valve stems, wheel condition, and directional or position-specific installation if applicable. On staggered F Sport cars, make sure the 245/45R20 tires are on the front and the 275/40R20 tires are on the rear, since the sizes are not interchangeable by position.

It also helps to look for any signs of rubbing at steering lock and under normal suspension compression, especially if the car has non-original wheels. After a short road test, recheck inflation pressure and look over the sidewalls and tread faces for any unusual contact pattern that might point to clearance or alignment concerns.

Tires on a 2019 Lexus LS500 should be inspected regularly for pressure loss, uneven tread wear, cuts, bulges, and sidewall damage, especially if the car is driven infrequently or stored for long periods. A quick visual check before routine use and a more deliberate inspection before longer trips is a sensible habit for a modern luxury sedan with low-profile tire fitments.

Low-profile 19-inch and 20-inch tires can make wheel damage and road-impact issues easier to overlook until drivability changes appear. Owners should also keep an eye on age-related deterioration, because a car that spends a lot of time parked can have tires that look acceptable at first glance but still deserve closer inspection before regular road use.
