The 2008 Lexus LS600h brought hybrid power into the flagship luxury-sedan segment without giving up the long-wheelbase presence and quiet highway character buyers expected from the LS line. It is a highly technical car from an era when wheel and tire choices were already closely tied to ride quality, handling balance, and visual proportion. For this exact model, tire fitment centers on two radial sizes, 235/50R18 and 245/45R19, both used on the LS600h L. That gives you a real choice between 18-inch and 19-inch wheel fitment, along with differences in available brands, tire series, and sidewall presentation. The key is matching the tire to the actual wheel setup on the car before selecting by style or performance character.
Which Tire Size Is Right for The 2008 Lexus LS600h
The 2008 Lexus LS600h uses two primary tire sizes, and the first step is confirming whether the car is on 18-inch or 19-inch wheels. Both fitments are radial and both appear on the LS600h L, so the real decision starts with wheel diameter, then moves to the tire's series, sidewall style, and overall character within the correct size.
235/50R18 is a metric radial size in which 235 identifies the section width in millimeters, 50 is the aspect ratio, R designates radial construction, and 18 is the wheel diameter in inches. On the 2008 Lexus LS600h, this size suits the 18-inch wheel fitment and keeps the selection within a modern radial format. Available choices include BFGoodrich, Nitto, and Pro-Trac, with blackwall, redline, and raised white letter sidewall presentations across series such as g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, Nitto NT555 G2, and Street Pro III. This size is worth evaluating if the car is still on 18-inch wheels and you want the broadest appearance variety.
245/45R19 is also a metric radial size, with 245 indicating section width in millimeters, 45 identifying the aspect ratio, R marking radial construction, and 19 calling for a 19-inch rim. For the 2008 Lexus LS600h, this size belongs to the 19-inch wheel fitment and should be selected only after confirming that larger wheel diameter. Product choices here include BFGoodrich and Nitto in blackwall form, with series such as g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. This fitment makes sense when the car already wears 19-inch wheels and the goal is staying with the correct diameter while comparing series and rim-width compatibility.
Sub-model fitment is straightforward here because the covered LS600h L uses both primary tire sizes. What matters most is not trim identification alone, but confirming whether the car has 18-inch or 19-inch wheels before choosing a tire.

2008 Lexus LS600h L
The 2008 Lexus LS600h L uses both 235/50R18 and 245/45R19 radial tire fitments, so wheel diameter is the deciding factor before anything else. Once the wheel size is confirmed, the tire choice comes down to comparing available brands, series, sidewall treatment, and rim-width suitability within the correct 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 2008 Lexus LS600h Tires for Sale
Available 2008 Lexus LS600h tires cover both primary sizes and include BFGoodrich, Nitto, and Pro-Trac options. Buyers can compare blackwall, redline, and raised white letter styling in 235/50R18, while 245/45R19 stays focused on blackwall radial performance-oriented series.
These 2008 Lexus LS600h FAQs focus on the two correct tire sizes, 18-inch versus 19-inch wheel fitment, available radial choices, appearance options, and the checks that matter before regular road use or after modifications.
Tire Size & Fitment
What tire size fits a 2008 Lexus LS600h?
The 2008 Lexus LS600h uses two primary tire sizes: 235/50R18 and 245/45R19. Both are radial fitments, and both are associated with the LS600h L, so the correct choice depends on which wheel diameter is actually on the car rather than on a simple trim-name assumption.
That means the first check should be the wheel itself. An 18-inch wheel takes 235/50R18, while a 19-inch wheel takes 245/45R19. Cars that have had wheel changes over the years should be inspected carefully, since selecting by model name alone can lead to ordering the right tire size for the wrong wheel diameter.
What size rim does a 2008 Lexus LS600h use?
A 2008 Lexus LS600h can use either an 18-inch or 19-inch rim, depending on which of its two primary tire sizes is on the car. The 235/50R18 fitment uses an 18-inch rim, and the 245/45R19 fitment uses a 19-inch rim.
Rim diameter is the most important fitment checkpoint on this vehicle because both sizes are valid, but they are not interchangeable across wheel diameters. Measuring the wheel or reading the existing tire size is the safest place to start, especially if the car has aftermarket wheels or has changed hands several times.
Why does the 2008 Lexus LS600h have more than one tire size?
The 2008 Lexus LS600h has more than one tire size because it appears with two wheel diameters: 18 inches and 19 inches. That creates two correct radial fitments, 235/50R18 and 245/45R19, rather than one universal size for every example of the model.
For the owner, the practical takeaway is simple: identify the wheel setup first, then compare tires within that size. Once diameter is confirmed, you can look at tire series, sidewall style, rim-width range, and other product differences without risking a mismatch between tire and wheel.
Choosing the Right Tire
What should I consider when choosing a tire for a 2008 Lexus LS600h?
Start with the correct primary size for the wheel on the car: 235/50R18 for 18-inch rims or 245/45R19 for 19-inch rims. From there, compare radial construction details such as tire series, sidewall style, rim-width range, and load figures where they are stated.
The 235/50R18 fitment offers the broadest variety, including blackwall, redline, and raised white letter options from BFGoodrich, Nitto, and Pro-Trac. The 245/45R19 fitment is narrower in appearance choice, staying with blackwall options, so buyers often focus more on series character and wheel compatibility in that size.
What sidewall styles are available for 2008 Lexus LS600h tires?
Sidewall style varies by size on the 2008 Lexus LS600h. In 235/50R18, available sidewall treatments include blackwall, redline, and RWL, while 245/45R19 options are available in blackwall form.
That matters most for buyers who want the tire to influence the car's overall presentation. A blackwall keeps the look understated and modern, while redline or raised white letter adds a more distinctive visual accent. The correct size still comes first, but sidewall styling becomes a useful final filter once wheel diameter is confirmed.
What brands offer tires for the 2008 Lexus LS600h?
Available tires for the 2008 Lexus LS600h come from BFGoodrich, Nitto, and Pro-Trac. BFGoodrich appears in both primary sizes, Nitto appears in both sizes as well, and Pro-Trac is available in the 235/50R18 fitment.
Brand choice should be considered alongside size, wheel diameter, tire series, and sidewall presentation rather than in isolation. A buyer with 18-inch wheels has more brand and appearance flexibility, while a buyer with 19-inch wheels will be comparing a tighter group of blackwall radial options within the correct 245/45R19 size.
Restoration & Appearance
Which tire should I choose for a period-style 2008 Lexus LS600h?
A period-style choice for a 2008 Lexus LS600h starts with retaining the wheel diameter already fitted to the car and using the matching primary size, either 235/50R18 or 245/45R19. Because this is a modern luxury sedan, the overall look is shaped more by wheel size and sidewall treatment than by vintage construction choices.
Among the available products, 235/50R18 offers the most appearance variety, including blackwall, redline, and raised white letter options. Buyers who want the car to keep a cleaner original-era luxury presentation usually begin with blackwall tires, while more expressive sidewall styles can create a custom look that is less tied to stock visual character.
Which sidewall style suits a period-style 2008 Lexus LS600h?
For a period-style 2008 Lexus LS600h, blackwall is the most restrained and natural-looking sidewall treatment among the available choices. It is offered in both 235/50R18 and 245/45R19, making it the easiest way to preserve the sedan's formal, contemporary luxury appearance.
Redline and raised white letter are available in 235/50R18 and can change the car's visual tone considerably. Those styles may appeal to owners building a more personalized look, but anyone aiming for a presentation closer to the LS600h's original showroom character will usually keep the emphasis on the correct size and a simple black sidewall.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2008 Lexus LS600h?
Yes, modifications can affect tire fitment on a 2008 Lexus LS600h even when the tire size itself is correct. Aftermarket wheels, changes in wheel width, suspension lowering, and altered offsets can all change how a 235/50R18 or 245/45R19 tire sits in the wheel opening.
That is why wheel diameter alone is not the only checkpoint on a modified car. Clearance at the fender, suspension, and steering components should be reviewed, and the wheel's width should be compared with the tire's intended rim range where that specification is available. Those checks become especially important before selecting a different series or sidewall style.
What should I inspect before driving a 2008 Lexus LS600h on new tires?
Before driving a 2008 Lexus LS600h on new tires, inspect the wheels for the correct diameter, confirm that each tire size matches the wheel, and check inflation, valve condition, and overall installation quality. It also helps to verify that there is no rubbing at full steering lock or over suspension movement.
A careful first inspection should also include tread and sidewall condition on any remaining older tires, especially on a vehicle that may have spent time parked. Uneven wear, cuts, bulges, or slow air loss can point to alignment, wheel, or suspension issues that should be addressed before expecting the new tires to wear and ride properly.
How often should tires on a 2008 Lexus LS600h be inspected?
Tires on a 2008 Lexus LS600h should be inspected regularly, not just when tread looks low. A quick visual check for pressure loss, cracking, cuts, bulges, and uneven wear is worthwhile before routine driving, and a more thorough inspection makes sense before a longer trip or after the car has been stored.
That habit matters on luxury cars that may see irregular use, because age and inactivity can affect a tire even when mileage stays low. Looking at both the tire and the wheel setup helps catch issues early, particularly if the car has 18-inch and 19-inch fitments appearing in the market and there is any doubt about what is mounted now.
