The 1991 Lexus LS400 introduced Lexus as a serious luxury contender, pairing quiet highway manners with the kind of refinement that made buyers look closely at every detail of the car. For owners today, tire choice still plays a major role in preserving that smooth, composed character. The 1991 Lexus LS400 uses a 205/65R15 radial tire on a 15-inch rim, so the main decision is less about multiple fitments and more about selecting the right presentation within the correct size. In this size, available choices include BFGoodrich Silvertown Radial tires with either a 2 Inch Whitewall or Redline sidewall. That makes it especially important to balance appearance, wheel compatibility, and intended road use.
Which Tire Size Is Right for The 1991 Lexus LS400
The 1991 Lexus LS400 uses one primary tire size: 205/65R15. It is a radial tire fitted to a 15-inch rim, and the covered LS400 Base sub-model uses the same fitment. That means the real choice is selecting the sidewall style and product presentation that best suits the car while still confirming wheel width and overall vehicle setup before installation.
205/65R15 is a metric radial size. The 205 identifies nominal section width in millimeters, 65 is the aspect ratio, R indicates radial construction, and 15 is the rim diameter in inches. On a 1991 Lexus LS400, this size supports the car’s modern luxury-touring character and keeps the fitment grounded in the correct radial format. Available options in this size include BFGoodrich Silvertown Radial tires with Wide Whitewall or Redline sidewall styling, giving the buyer a choice between a more formal presentation and a more performance-inspired period look.
Tire fitment is straightforward for the covered 1991 Lexus LS400 sub-models. The key check is still confirming that the car remains on the correct 15-inch wheel setup before choosing among the available sidewall and product options.

1991 Lexus LS400 Base
The 1991 Lexus LS400 Base uses the same 205/65R15 radial fitment as the model line covered here. That keeps tire selection focused on wheel-width compatibility, appearance, and whether a Wide Whitewall or Redline sidewall better matches the way the car is being presented.
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.

Common questions for the 1991 Lexus LS400 usually center on the correct 205/65R15 fitment, 15-inch wheel compatibility, sidewall style selection, and what to inspect before putting a luxury sedan that may see limited use back on the road.
Tire Size & Fitment
What tire size fits a 1991 Lexus LS400?
The 1991 Lexus LS400 uses a 205/65R15 radial tire. That size is the primary fitment for the covered vehicle, including the LS400 Base, and it mounts on a 15-inch rim.
The size breaks down into a 205-millimeter nominal section width, a 65-series aspect ratio, radial construction, and a 15-inch rim diameter. Since there is only one primary size here, the real next step is confirming that the car still has the correct wheel setup and then choosing the sidewall treatment that best matches the car’s appearance and intended use.
What size rim does a 1991 Lexus LS400 use?
The 1991 Lexus LS400 uses a 15-inch rim with its 205/65R15 tire size. Available tires in this fitment are built for that rim diameter and share a recommended rim-width range of 5.50 to 7.50 inches.
Rim diameter is the first non-negotiable measurement, but width matters too. A car that has been fitted with different wheels over the years should be checked carefully before choosing tires, since the correct 15-inch diameter alone does not confirm that the wheel width and overall setup remain appropriate for the 205/65R15 fitment.
Does the 1991 Lexus LS400 Base use the same tire size?
Yes. The 1991 Lexus LS400 Base uses the same 205/65R15 radial tire size as the covered LS400 fitment. That keeps the selection process simple because there is no second primary size to sort through by sub-model.
Even with shared fitment, it is still smart to check the actual wheels on the car before replacing tires. A sedan that has been modified with aftermarket wheels, suspension changes, or a different stance may need a closer look at wheel width and clearance before settling on a replacement tire in the correct factory-style size.
Choosing the Right Tire
What should I consider when choosing a 205/65R15 tire for a 1991 Lexus LS400?
Start with the correct size, 205/65R15, and confirm radial construction on a 15-inch wheel. From there, compare the sidewall treatment, rim-width compatibility, and whether the tire’s overall presentation suits a refined luxury sedan or a more personalized look.
For this LS400, available choices share the same BFGoodrich Silvertown Radial series, the same 1400@35 psi maximum load figure, and the same 5.50 to 7.50-inch rim-width range. That means the most visible decision is appearance, especially whether a 2 Inch Whitewall or Redline better complements the car’s styling and the owner’s goals.
What sidewall styles are available for 1991 Lexus LS400 tires?
The available 205/65R15 tires for the 1991 Lexus LS400 come with either a 2 Inch Whitewall or a Redline sidewall. Both are offered in the BFGoodrich Silvertown Radial series and keep the car in the correct radial size and 15-inch rim diameter.
The whitewall option gives the car a more formal, upscale presentation, while the redline creates a sportier period-style accent. Since sidewall treatment changes the look of the car more than the fitment itself, many buyers choose between these two based on restoration direction, visual taste, and how original or personalized they want the finished car to appear.
What brands offer tires for the 1991 Lexus LS400?
BFGoodrich is the available brand in the 205/65R15 fitment for the 1991 Lexus LS400. The current choices are within the Silvertown Radial series and differ by sidewall style rather than by brand-to-brand construction changes.
Because the brand selection here is focused, the comparison becomes more about appearance and wheel compatibility than about choosing among multiple manufacturers. That can actually simplify the process for an LS400 owner, since the key decisions are whether the car should wear a 2 Inch Whitewall or Redline and whether the existing wheels remain within the proper width range.
Restoration & Appearance
Which tire should I choose for a period-style 1991 Lexus LS400?
A period-style choice for a 1991 Lexus LS400 starts with the correct 205/65R15 radial size. From there, the decision usually comes down to whether the car looks more appropriate with the formal character of a 2 Inch Whitewall or the more assertive visual accent of a Redline sidewall.
Since both available options share the same BFGoodrich Silvertown Radial series and core fitment, appearance becomes the main differentiator. Buyers pursuing a very specific restoration direction should compare the tire choice against original photos, showroom literature, marque references, or long-term ownership history so the finished presentation suits the car’s intended story.
How does tire construction affect the appearance of a restored 1991 Lexus LS400?
For the 1991 Lexus LS400, the primary fitment is already a radial, so the construction choice does not involve switching from an earlier bias-ply look. Instead, the visual effect comes more from the sidewall treatment within the correct 205/65R15 radial size.
That makes this car different from many older collector vehicles where construction changes can dramatically alter stance and character. On an LS400 restoration or presentation-focused build, keeping the correct size and 15-inch wheel relationship matters first, then selecting whether a Whitewall or Redline better matches the sedan’s luxury image or a more customized appearance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1991 Lexus LS400?
Yes. The 1991 Lexus LS400 uses a 205/65R15 tire on a 15-inch rim, but modifications can still affect whether that fitment remains appropriate in practice. Aftermarket wheels, altered wheel width, suspension changes, or body adjustments can all change the clearance picture.
A car that still carries the correct nominal tire size may behave differently if the wheel specifications or ride height have changed. Checking wheel width, steering clearance, and fender space before installing replacement tires is especially important on an older luxury sedan that may have seen changes over time or passed through multiple owners.
What should I inspect before driving a 1991 Lexus LS400 on new tires?
Before putting a 1991 Lexus LS400 back into regular road use on new tires, inspect the wheels for damage, confirm the 15-inch rim setup, and make sure the tires are mounted in the correct 205/65R15 size. Tire pressure should also be set appropriately, and the car should be checked for any signs of suspension or alignment issues.
A luxury sedan that has been stored or driven infrequently deserves extra attention before a longer run. Look for uneven wear patterns on the old tires, fluid leaks that may affect suspension components, and any rubbing marks inside the wheel openings so the new tires begin service on a stable, properly sorted chassis.
How should 205/65R15 tires on a collector 1991 Lexus LS400 be maintained?
205/65R15 tires on a collector 1991 Lexus LS400 should be maintained with regular pressure checks, periodic visual inspections, and routine attention to tread wear and sidewall condition. Even a low-mileage car can develop age-related issues if it sits for long periods without moving.
Storage conditions matter just as much as mileage on a car like this. Keeping the LS400 away from prolonged sunlight, excessive heat, moisture, and ozone sources helps preserve the tires, while occasional movement of the vehicle can reduce flat-spotting and give the owner a chance to catch early signs of cracking, cuts, bulges, or air loss.
