The 2009 Lexus Trucks LX570 sits in the full-size luxury SUV world with a strong mix of long-distance comfort, substantial curb presence, and genuine truck-based capability. Buyers looking after one today are often balancing everyday drivability with the need to keep the vehicle's stance and road manners in line with its original character. This model uses a 285/50R20 radial tire on a 20-inch rim, so the fitment question is straightforward at the size level. The real decision is choosing the right tire within that size and confirming that wheel setup, clearance, and overall condition still match the vehicle. That matters even more if the LX570 has seen wheel, suspension, or tire changes over time.
Which Tire Size Is Right for The 2009 Lexus Trucks LX570
The 2009 Lexus Trucks LX570 uses one primary tire size: 285/50R20, and it is a radial fitment for a 20-inch rim. The LX570 Base uses this same size, so the main decision is not which primary size fits, but which 285/50R20 tire best matches your wheel setup, intended road use, and overall vehicle condition.
285/50R20 is a modern metric radial size in which 285 identifies nominal section width in millimeters, 50 is the aspect ratio, R denotes radial construction, and 20 is the rim diameter in inches. On the 2009 Lexus Trucks LX570, this format suits the vehicle's contemporary luxury SUV character and 20-inch wheel package. Because the fitment is already a modern radial, the focus shifts away from construction conversion and toward selecting the right tire within the size. It is also wise to confirm the actual wheel dimensions and clearance if the LX570 has aftermarket wheels, suspension changes, or a replacement wheel package.
Fitment is straightforward across the covered 2009 Lexus Trucks LX570 sub-models because the same tire size is used here. Checking the exact sub-model still helps confirm that the wheel and tire setup on the vehicle has not been changed from stock-style sizing.

Frequently Asked Questions
Tire questions for the 2009 Lexus Trucks LX570 usually center on its single 285/50R20 fitment, 20-inch wheel compatibility, product selection within that size, and the checks worth making before regular road use.
Tire Size & Fitment
What tire size fits a 2009 Lexus Trucks LX570?
The 2009 Lexus Trucks LX570 uses a 285/50R20 tire size. This is a radial fitment and it is the primary size associated with this vehicle, including the LX570 Base sub-model.
That makes the size decision fairly simple, but it is still important to confirm that the SUV is actually running the correct 20-inch wheels before replacing tires. If a previous owner changed the wheels, suspension height, or overall tire setup, the tire currently on the vehicle may not reflect the intended fitment.
What size rim does a 2009 Lexus Trucks LX570 use?
The 2009 Lexus Trucks LX570 uses a 20-inch rim with its 285/50R20 tire size. The tire size itself confirms that the intended wheel diameter is 20 inches.
Rim diameter is only one part of the fitment picture, so wheel width and overall wheel design should also be checked before mounting new tires. That becomes especially important when the vehicle has aftermarket wheels, since a 20-inch diameter alone does not guarantee that every wheel is equally suitable for the same tire.
Does the 2009 Lexus Trucks LX570 Base use the same tire size?
Yes. The 2009 Lexus Trucks LX570 Base uses the same 285/50R20 radial tire size as the core vehicle fitment. There is no separate primary tire size shown here for the Base sub-model.
That consistency simplifies replacement shopping because the question is less about sub-model variation and more about choosing the right tire within the correct size. It is still smart to inspect the vehicle itself, since replacement wheels or altered suspension can change what is currently mounted even when the original fitment remains straightforward.
Choosing the Right Tire
What should I consider when choosing a 285/50R20 tire for a 2009 Lexus Trucks LX570?
Start with the confirmed primary fitment: 285/50R20 on a 20-inch rim. Once that is established, the main considerations are whether the tire matches the wheel setup on the vehicle and whether it suits the way the LX570 is actually driven.
A luxury SUV like the LX570 benefits from careful attention to overall tire condition, load suitability, and compatibility with the existing wheels. It also helps to compare the new tire against the vehicle's current setup for clearance at the suspension, steering, and fender areas, especially if the truck has had any wheel or suspension changes.
How do I choose between available 285/50R20 tires for a 2009 Lexus Trucks LX570?
Choosing between 285/50R20 tires for a 2009 Lexus Trucks LX570 comes down to staying with the correct size and then comparing the characteristics that matter for your vehicle. Wheel compatibility, intended use, and the condition of the existing setup should guide the decision more than appearance alone.
A useful approach is to inspect the current wheels, verify the actual tire size on the vehicle, and think about how the LX570 is used most often. Daily road driving, occasional long-distance travel, and a vehicle that has been modified can each shift what should be checked before settling on one tire over another in the same size.
What rim-fitment details should I compare when choosing tires for a 2009 Lexus Trucks LX570?
The first rim-fitment detail is diameter, and the 2009 Lexus Trucks LX570 uses a 20-inch wheel with its 285/50R20 tire size. After that, wheel width and the actual wheel design should be checked so the tire and wheel work together properly.
This matters most when the vehicle no longer has its original-style wheels. A tire can share the correct diameter but still need closer review if the wheel width, offset, or overall setup has changed, so it is worth checking those points before mounting new tires and assuming the existing wheel package is unchanged.
Restoration & Appearance
Which tire should I choose for a period-style 2009 Lexus Trucks LX570?
For a period-style 2009 Lexus Trucks LX570, the starting point is retaining the correct primary fitment of 285/50R20 on a 20-inch rim. Because this is already a modern radial size, preserving the proper overall look usually means staying with the correct size and avoiding mismatched wheel-and-tire combinations.
Appearance on a late-model luxury SUV is shaped as much by stance and proportion as by the tire itself. A tire that matches the intended size helps keep the vehicle visually balanced, while oversized or undersized replacements can change that impression quickly, so wheel setup and overall presentation deserve as much attention as the tire choice.
Does correct tire fitment matter for a 2009 Lexus Trucks LX570 restoration?
Yes, correct tire fitment matters on a 2009 Lexus Trucks LX570 restoration because the tire size directly affects the vehicle's stance, wheel appearance, and overall presentation. Using the proper 285/50R20 size keeps the restoration grounded in the fitment associated with this model.
Even on newer collector-oriented vehicles, incorrect tire sizing can make an otherwise well-finished truck look off-balance. A careful restoration should confirm the wheel diameter actually on the vehicle and check that previous owners did not substitute a different wheel-and-tire package, since that can alter both appearance and fitment without being obvious at first glance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2009 Lexus Trucks LX570?
Yes. Modifications can affect tire fitment on a 2009 Lexus Trucks LX570 even when the original tire size is 285/50R20. Changes to wheels, suspension height, alignment, or body clearance can all influence how that size works on the vehicle.
An LX570 with aftermarket wheels may still use a 20-inch rim, but width, offset, and tire clearance can differ from the intended setup. It is smart to inspect fender clearance, steering travel, and suspension space before replacement so the new tires match the vehicle as it sits now rather than only the original specification.
What should I inspect before driving a 2009 Lexus Trucks LX570 on new tires?
Before driving a 2009 Lexus Trucks LX570 on new tires, inspect the wheels, valve stems, and overall mounting condition, then confirm that the tires are the correct 285/50R20 size for the vehicle. Tire pressure should also be set correctly before the SUV returns to regular road use.
A close visual check matters just as much on the rest of the vehicle. Look for rubbing at the fenders or suspension, make sure the steering turns cleanly without contact, and verify that no wheel damage or uneven wear pattern suggests an alignment or suspension issue that could shorten tire life right away.
How often should tires on a 2009 Lexus Trucks LX570 be inspected?
Tires on a 2009 Lexus Trucks LX570 should be inspected regularly, not just when tread looks worn. Routine checks for pressure loss, uneven wear, cracking, cuts, bulges, and any change in ride feel can catch problems early before they become more serious.
Inspection is especially important on vehicles that spend long periods parked or see seasonal use. Even when mileage stays low, age and storage conditions can affect tire condition, so it helps to examine the sidewalls and tread closely before longer drives and after the vehicle has been sitting for an extended time.
