The 2016 Lexus Trucks LX570 sits in the modern luxury SUV world with the presence, weight, and long-distance composure expected of a flagship body-on-frame vehicle. Buyers often come to this model balancing everyday road manners with the need to preserve the LX570’s upscale look and proper stance. For this exact vehicle, tire fitment centers on two primary radial sizes, 275/50R21 and 285/50R20, tied directly to wheel diameter. That makes the real decision less about vintage-style construction and more about confirming which wheel setup is on the vehicle. Before choosing tires, verify whether the LX570 is wearing its 20-inch or 21-inch wheels.
Which Tire Size Is Right for The 2016 Lexus Trucks LX570
The 2016 Lexus Trucks LX570 uses two primary tire sizes, and the first thing to confirm is wheel diameter. Both sizes are radial, but one fits a 21-inch wheel and the other fits a 20-inch wheel, so selecting the right tire starts with identifying the actual wheel setup on the vehicle. Since the LX570 Base can use either size, wheel confirmation matters more than trim name alone.
The 275/50R21 size uses a modern metric format: 275 is the nominal section width in millimeters, 50 is the aspect ratio, R identifies radial construction, and 21 is the rim diameter in inches. On the 2016 Lexus Trucks LX570, this size suits a 21-inch wheel and reflects a contemporary SUV tire specification rather than an older bias-ply or alphanumeric system. Its sizing helps preserve the vehicle’s intended proportions and road-going character. Choose this size only after confirming that the LX570 is actually equipped with 21-inch wheels, not the alternate 20-inch setup.
The 285/50R20 size is also a modern metric radial format, with 285 indicating nominal section width in millimeters, 50 showing the aspect ratio, and 20 identifying the rim diameter in inches. For the 2016 Lexus Trucks LX570, this size belongs to the 20-inch wheel configuration and represents a separate primary fitment rather than an interchangeable variation of the 21-inch tire. It is slightly wider in section than the 275/50R21 format. This is the size to evaluate when the vehicle is fitted with 20-inch wheels or has retained that wheel package.
Sub-model fitment is straightforward here because the 2016 Lexus Trucks LX570 Base can use either of the vehicle’s two primary tire sizes. The important check is not trim level, but whether the SUV is fitted with 20-inch or 21-inch wheels before selecting a tire.

Frequently Asked Questions
Owners of a 2016 Lexus Trucks LX570 usually need to confirm the correct tire size by wheel diameter first. The questions below focus on fitment, radial sizing, wheel compatibility, selection factors, and the checks worth making before regular road use.
Tire Size & Fitment
What tire size fits a 2016 Lexus Trucks LX570?
The 2016 Lexus Trucks LX570 uses two primary tire sizes: 275/50R21 and 285/50R20. Both are radial sizes, but they are not just alternate markings for the same wheel, because each one is tied to a different rim diameter.
The key step is confirming whether the vehicle has 21-inch or 20-inch wheels. A trim badge alone does not settle the question here, since the LX570 Base can use either setup, so the actual wheel diameter on the vehicle should be checked before choosing a tire.
What size rim does a 2016 Lexus Trucks LX570 use?
A 2016 Lexus Trucks LX570 can use either a 21-inch rim or a 20-inch rim, depending on which of its two primary tire sizes is on the vehicle. The 275/50R21 size fits a 21-inch rim, while the 285/50R20 size fits a 20-inch rim.
That rim difference is the most important fitment detail on this vehicle. Before replacing tires, check the wheel itself and the current tire sidewall so the new tire matches the actual rim diameter, not just an assumed specification for the model.
Why does the 2016 Lexus Trucks LX570 have more than one tire size?
The 2016 Lexus Trucks LX570 has more than one tire size because it can be equipped with more than one wheel diameter. In this case, the two primary radial sizes are 275/50R21 for a 21-inch wheel and 285/50R20 for a 20-inch wheel.
That means the correct tire depends on the wheel package actually installed on the SUV. The most practical approach is to verify the tire size already mounted, confirm the wheel diameter, and then check for any wheel changes or modifications made by a previous owner.
Choosing the Right Tire
What should I consider when choosing a tire for a 2016 Lexus Trucks LX570?
Start with the correct primary size for the wheel on the vehicle, either 275/50R21 or 285/50R20. Since both are radial fitments, the main selection issue is matching the tire to the actual wheel diameter rather than deciding between older and newer construction styles.
After size is confirmed, compare the tire’s overall dimensions, intended road use, and how it suits the LX570’s weight and luxury-SUV character. It also helps to inspect whether the vehicle still has its original wheel setup or has been changed to aftermarket wheels with different width or offset.
How do I choose between the available 2016 Lexus Trucks LX570 tire sizes?
Choosing between the LX570’s two tire sizes is not a matter of preference alone, because each one belongs to a different wheel diameter. The 275/50R21 size is for 21-inch wheels, while 285/50R20 is for 20-inch wheels.
Once the wheel size is confirmed, the matching tire size should follow that setup. A useful double-check is to compare the wheel diameter, the size marked on the current tire, and the clearance around the suspension and body in case the vehicle has been altered from stock.
What rim-fitment details should I compare when choosing 2016 Lexus Trucks LX570 tires?
The most important rim-fitment detail is diameter, because the 2016 Lexus Trucks LX570 uses both 20-inch and 21-inch wheel setups. The tire must match that diameter exactly, so a 275/50R21 cannot be mounted in place of a 285/50R20 without a wheel change.
Wheel width and overall tire proportions also deserve attention, especially if the SUV has aftermarket wheels. Checking the existing wheel setup, reading the sidewall markings carefully, and confirming clearance around steering and suspension components will help avoid ordering a tire for the wrong rim.
Restoration & Appearance
Does correct tire fitment matter for a 2016 Lexus Trucks LX570 restoration or preservation project?
Yes, correct tire fitment matters on a 2016 Lexus Trucks LX570 even in a preservation-minded project. Because this model uses modern radial sizing tied directly to either 20-inch or 21-inch wheels, the wrong size can alter the vehicle’s stance, wheel relationship, and overall presentation.
A careful approach starts with confirming which wheel package belongs on the specific SUV in front of you. Owners focused on maintaining an authentic appearance should also review service history, original purchase materials, or marque-specific references before changing wheel-and-tire combinations for cosmetic reasons alone.
How does tire size affect the appearance of a 2016 Lexus Trucks LX570?
Tire size has a visible effect on a 2016 Lexus Trucks LX570 because the SUV’s proportions are built around either a 275/50R21 or 285/50R20 radial setup. The wheel diameter and sidewall profile together shape how full the wheel openings look and how the vehicle sits visually.
That makes it worth matching the tire to the intended wheel package instead of treating the two sizes as casual substitutes. On a preserved or carefully kept LX570, staying with the proper size for the installed wheels helps maintain a balanced, intentional look rather than an improvised one.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2016 Lexus Trucks LX570?
Yes, modifications can affect tire fitment on a 2016 Lexus Trucks LX570. Changes such as aftermarket wheels, altered wheel offset, suspension adjustments, or body modifications can influence whether the original 275/50R21 or 285/50R20 sizing still clears properly in normal driving and steering movement.
That is why the current setup should be inspected before replacing tires. Even when the sidewall shows one of the correct primary sizes, wheel changes can alter how that tire sits in the wheelwell, so clearance around suspension parts, fenders, and lock-to-lock steering should be checked.
What should I inspect before driving a 2016 Lexus Trucks LX570 on new tires?
Before driving a 2016 Lexus Trucks LX570 on new tires, inspect the wheel diameter, tire size marking, inflation pressure, and the condition of the wheels themselves. It is also smart to look for uneven wear patterns, visible damage, or signs that the old tires were contacting suspension or body components.
A short follow-up check after installation is worthwhile as well. Watch for vibration, rubbing, or steering changes, and recheck pressure once the tires have settled in service. On a heavy luxury SUV like the LX570, those basic checks help confirm that the tire and wheel setup is working as intended.
How often should tires on a 2016 Lexus Trucks LX570 be inspected?
Tires on a 2016 Lexus Trucks LX570 should be inspected regularly, not just when replacement time arrives. Routine checks should include tread condition, air pressure, cuts, bulges, cracking, and any signs of irregular wear that could point to alignment or suspension issues.
The inspection interval becomes even more important if the SUV is driven infrequently or sits for long periods. A quick visual check before road use and a more careful inspection at regular service intervals can help catch age-related problems or slow air loss before they turn into a roadside issue.
