Lexus LS400 Tires

The Lexus LS400 uses two tire sizes across its 1990 to 2000 production run. Models from 1990 through 1992 use 205/65R15 on 15-inch rims, while models from 1993 through 2000 use 225/60R16 on 16-inch rims. Both are radial tire sizes in modern metric format, but they are not interchangeable because the wheel diameters differ.

The practical step is to confirm the model year and then physically verify the wheel diameter on the car, especially if the Lexus LS400 has had wheel changes over the years. A 15-inch tire will not fit a 16-inch wheel, and a 16-inch tire will not fit a 15-inch wheel, so wheel diameter comes first and sidewall style comes second.

On a Lexus LS400, 205/65R15 means the tire has a 205 millimeter section width, a 65-series aspect ratio, radial construction, and a 15-inch rim diameter. That size belongs to 1990, 1991, and 1992 Lexus LS400 models in this fitment group. It is a modern metric radial size rather than an older alphanumeric or numeric bias-ply code.

Knowing how to read the code helps you separate width, profile, and wheel fit before you focus on sidewall appearance. If your Lexus LS400 is an early car and still carries 15-inch wheels, this is the size to match first, then you can choose among the available redline or wide whitewall radial options according to the look you want.

The Lexus LS400 uses two rim diameters across the years covered here. Early cars from 1990 through 1992 use 15-inch rims with 205/65R15 tires, and later cars from 1993 through 2000 use 16-inch rims with 225/60R16 tires. The rim diameter is the final number in each metric tire size and is the non-negotiable fitment dimension.

That wheel change matters more than cosmetic differences in sidewall style or brand choice. If a Lexus LS400 has had replacement wheels installed at some point, check the wheel stamping or measure the rim before selecting a tire, because year alone may not tell the whole story on a long-owned luxury sedan.

A 1993 Lexus LS400 falls into the later fitment group and uses 225/60R16 with a 16-inch rim. That distinguishes it from 1990 through 1992 Lexus LS400 models, which use 205/65R15 on 15-inch rims. The size code on the existing tire and the diameter of the wheel should agree with each other.

For a buyer or restorer, the safest approach is to verify three things together: model year, tire sidewall size, and actual wheel diameter. On a Lexus LS400 that has changed hands several times, wheel swaps are always possible, so matching all three points keeps you from choosing a tire that looks correct on paper but does not fit the car in the garage.

Lexus LS400 tires in this range are offered with several sidewall styles, including wide whitewall, redline, pin white stripe, narrow whitewall, and raised yellow letter depending on size. The 205/65R15 offerings include wide whitewall and redline, while the 225/60R16 range expands to raised yellow letter, redline, pin white stripe, wide whitewall, and narrow whitewall. All of these are radial tires.

That variety lets an owner tune the appearance of a Lexus LS400 from restrained luxury to a more period-custom or enthusiast look. If authenticity of presentation matters, compare the sidewall treatment to the car’s intended style and era, because a conservative luxury sedan generally reads differently on a fine stripe or plain treatment than it does on a bold lettered or wide whitewall tire.

The Lexus LS400 tire offerings here come from BFGoodrich, Goodyear, and Travelstar. BFGoodrich covers both 205/65R15 and 225/60R16 with Silvertown Radial options, while Goodyear and Travelstar appear in the 225/60R16 size. All listed products for the Lexus LS400 are radial-construction tires.

Brand choice is only meaningful after the size and wheel diameter are correct. Once that fitment point is settled, the decision usually comes down to the visual style you want, the rim-width range of the wheel on the car, and whether you prefer a more understated luxury presentation or a more stylized period look.

The Lexus LS400 offerings here include three series: BFGoodrich Silvertown Radial, Goodyear Eagle NASCAR, and Travelstar UN106. All three are radial tires, but they differ primarily in brand identity and sidewall presentation within the listed sizes rather than in a shift from one construction technology to another. Silvertown Radial appears in the broadest range of sidewall styles, while Eagle NASCAR is the raised yellow letter option and UN106 is the narrow whitewall option in 225/60R16.

For most Lexus LS400 owners, the series decision is less about basic fit and more about visual character. Start by matching the correct size to the car’s year and wheel diameter, then compare which series offers the sidewall treatment that best suits the sedan’s intended look, whether that is formal, custom, or more performance-oriented.

A Lexus LS400 should be stored on a clean, dry surface away from direct sunlight, ozone sources, and long periods of static load if possible. Tires age from time, environment, and inactivity as much as from mileage, and luxury sedans that sit for extended periods can develop flat spotting or stress in the casing. Keeping inflation set correctly also helps the tire hold its shape during storage.

If the Lexus LS400 is a collector-driven car, move it periodically or support it in a way that reduces prolonged load concentration. Clean storage conditions and regular inflation checks will do more for tire life than occasional cosmetic care, and they also help preserve the quiet, smooth driving character that owners usually want from an LS400.

Tires on a Lexus LS400 should be inspected regularly even if the car is driven only occasionally. Check for cracking, bulges, uneven wear, puncture damage, aging around the sidewall and tread blocks, and any sign that the tire is losing air. Collector cars and low-mileage luxury sedans can hide age-related deterioration because the tread may still look deep.

A good routine is to inspect the Lexus LS400 before each drive and more carefully at seasonal intervals, especially if the car spends much of its time parked. That inspection should include wheel condition and inflation pressure, because a car that feels smooth at moderate speed can still be carrying an aging tire that deserves replacement before more serious road use.

Tires on a Lexus LS400 should be replaced when age, cracking, hardening, structural damage, repeated air loss, or irregular wear indicates the casing is no longer trustworthy, even if the tread still appears usable. Tread depth alone is not a reliable measure on a low-use collector or weekend car. Time and storage history matter just as much as mileage on a luxury sedan that may spend long periods parked.

If a Lexus LS400 has older tires that look presentable but feel hardened or show sidewall deterioration, replacement is the prudent move before routine road use. Owners who drive infrequently sometimes underestimate age because the miles are low, but an infrequently used tire can still be past its safe service life long before the tread is worn out.

The listed Lexus LS400 tires are radial road tires in modern metric sizes, so they are intended for normal road use when they are the correct size for the wheel and are in proper service condition. Safety still depends on matching 205/65R15 to the 1990-1992 15-inch fitment group and 225/60R16 to the 1993-2000 16-inch fitment group. A correct size on the wrong wheel diameter is not safe and will not mount properly.

Roadworthiness also depends on the condition of the tire, wheel, suspension, and alignment on the individual Lexus LS400. Before regular driving, check inflation, inspect for visible age or damage, and make sure the car tracks properly, because a refined sedan can mask early warning signs better than a noisier or harsher-driving older vehicle.

Before driving a Lexus LS400, check that the tire size matches the wheel diameter, the inflation is appropriate, and the tires show no cracking, bulging, puncture damage, or severe uneven wear. Also look at valve stems and the wheel itself for any sign of damage or corrosion. On this model, confirming whether the car has 15-inch or 16-inch wheels is the first fitment check.

A short pre-drive inspection is especially worthwhile on a Lexus LS400 that is used intermittently, because issues often develop while the car is parked rather than while it is being driven. If the steering feels unsettled, the ride becomes unusually harsh, or the car pulls to one side, stop and inspect the tires and chassis before continuing.

A Lexus LS400 should always be driven at speeds appropriate to the condition, age, and type of tire currently fitted, not simply to the capability of the car itself. The listed sizes are modern radial formats suitable for normal road use when fresh and properly maintained, but an older collector tire or long-stored set should be treated more conservatively. Tire condition matters more than appearance alone.

For a Lexus LS400 that sees occasional use, build speed gradually after confirming pressure and condition, and avoid assuming that a low-mileage tire is automatically ready for sustained highway work. The car may be capable of effortless cruising, but the safe operating pace should always be set by the tires’ actual age, structural health, and maintenance history.
