The 2020 Lexus LC500h blends grand touring luxury with hybrid performance in a low, dramatic coupe that depends heavily on the right staggered tire setup. Its proportions, wheel design, and road manners all make tire choice more than a routine maintenance item. This model uses radial tires, with front fitment in either 245/40R21 or 245/45R20 and rear fitment in either 275/35R21 or 275/40R20. That means the first decision is confirming whether the car is on 20-inch or 21-inch wheels, then comparing the available tread patterns and sidewall presentations within the correct front-and-rear pairing. Getting that combination right helps preserve both appearance and intended handling balance.
Which Tire Size Is Right for The 2020 Lexus LC500h
The 2020 Lexus LC500h uses four primary tire sizes because it has a staggered front-and-rear setup offered in two wheel diameters. The key step is confirming whether the car is equipped with 20-inch or 21-inch wheels, since the front and rear sizes must match the correct rim diameter pairing. Once that is settled, the choice moves to tire series, brand, and sidewall style within the proper radial sizes.
In 245/40R21, 245 identifies the nominal section width in millimeters, 40 is the aspect ratio, R designates radial construction, and 21 is the wheel diameter in inches. On the 2020 Lexus LC500h, this is a front tire size used with the 21-inch staggered setup, so it works as part of a matched front-and-rear combination rather than as a stand-alone fitment. Its role is to preserve the intended relationship with the corresponding 275/35R21 rear size. Before choosing this size, confirm that the car is actually on 21-inch wheels and that both axle positions retain the proper staggered pairing.
In 245/45R20, the 245 is the nominal width in millimeters, 45 is the aspect ratio, R means radial, and 20 is the required rim diameter. This size serves as the front tire on the 20-inch setup for the 2020 Lexus LC500h and pairs with a wider 275/40R20 rear tire. Available choices include BFGoodrich, Nitto, and Pro-Trac, with blackwall, redline, and raised white letter sidewall presentations depending on the tire series. This is the size to evaluate when the car wears 20-inch front wheels and the goal is balancing correct staggered fitment with the preferred look and tire character.
A 275/35R21 tire uses a 275-millimeter nominal section width, a 35-series aspect ratio, radial construction, and a 21-inch wheel diameter. On the 2020 Lexus LC500h, this is the rear size used with the 21-inch wheel package, so it belongs with the matching 245/40R21 front fitment. Its wider section reflects the car's staggered setup and makes rear-wheel confirmation especially important before selecting replacements. This size should be chosen only after verifying that the rear wheels are 21-inch rims and that the car has not been changed to a different wheel and tire package.
In 275/40R20, 275 is the nominal section width in millimeters, 40 is the aspect ratio, R indicates radial construction, and 20 denotes the wheel diameter. This is the rear tire size for the 20-inch staggered setup on the 2020 Lexus LC500h, paired with a 245/45R20 front tire. Product choices include BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster, with blackwall, redline, and raised white letter options across several series. This size deserves close comparison when selecting a 20-inch rear tire because available products vary in sidewall presentation, rim-width specification, and intended tire character.
Fitment on the 2020 Lexus LC500h is straightforward in layout but still requires attention because the covered front and rear positions use different sizes. The important step is matching the correct axle position and confirming whether the car is on the 20-inch or 21-inch wheel package before choosing tires.

Owners of a 2020 Lexus LC500h usually need clarity on the staggered tire setup, 20-inch versus 21-inch wheel fitment, and how front and rear sizes pair together. These FAQs also cover brand and sidewall choices, selection factors, and practical checks before road use.
Tire Size & Fitment
What tire size fits a 2020 Lexus LC500h?
The 2020 Lexus LC500h uses a staggered radial tire setup rather than one size at all four corners. Front fitment is either 245/40R21 or 245/45R20, while rear fitment is either 275/35R21 or 275/40R20, depending on whether the car is equipped with 21-inch or 20-inch wheels.
That means the correct choice starts with confirming wheel diameter and axle position before comparing tire options. A front size should stay paired with the matching rear size for the same wheel package, and any car with changed wheels or previous tire substitutions should be checked carefully before replacements are selected.
What size rim does a 2020 Lexus LC500h use?
A 2020 Lexus LC500h uses either 20-inch or 21-inch rims, depending on the wheel package on the car. The 20-inch setup uses 245/45R20 front and 275/40R20 rear tires, while the 21-inch setup uses 245/40R21 front and 275/35R21 rear tires.
Rim diameter is the first thing to verify because none of these tire sizes cross over between 20-inch and 21-inch wheels. Checking the current wheel size directly on the vehicle is especially important if the car was purchased used or has had wheel changes, since the front and rear fitments must stay coordinated.
Why does the 2020 Lexus LC500h have more than one tire size?
The 2020 Lexus LC500h has more than one tire size because it uses a staggered setup and was fitted with two different wheel diameters. The front tires are narrower than the rear tires, and each wheel package has its own matched pair of sizes: one pair for 20-inch wheels and another for 21-inch wheels.
That layout means tire selection is really about identifying the complete setup already on the car, not choosing from four unrelated sizes. Once wheel diameter and axle position are confirmed, the remaining decision is which available tire series, brand, and sidewall treatment best suits the car’s look and intended driving use.
Choosing the Right Tire
What should I consider when choosing a 245/45R20 tire for a 2020 Lexus LC500h?
A 245/45R20 for the 2020 Lexus LC500h should be chosen as the front tire in the 20-inch staggered setup, not as a universal fitment. Available choices include several radial products from BFGoodrich, Nitto, and Pro-Trac, with differences in tire series, sidewall appearance, rim-width specification, and other product characteristics.
The practical comparison starts with making sure the car actually uses the 20-inch package and that the rear tires remain the matching 275/40R20 size. After that, it makes sense to compare blackwall versus redline or raised white letter presentation, along with the wheel width on the car and the type of road use expected.
What sidewall styles are available for 2020 Lexus LC500h tires?
For the 20-inch LC500h sizes with available products, sidewall styles include blackwall, redline, and RWL, or raised white letter. Those choices appear in both 245/45R20 front tires and 275/40R20 rear tires, giving owners different visual directions without changing the basic staggered radial fitment.
That matters most when the car’s appearance is part of the decision, especially if the goal is a more understated modern look or a more distinctive sidewall treatment. The right sidewall choice still has to be made within the correct size for the axle position, with wheel diameter and rear-to-front pairing confirmed first.
What brands offer tires for the 2020 Lexus LC500h?
Available 20-inch tires for the 2020 Lexus LC500h come from BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster. Those brands appear across the front 245/45R20 and rear 275/40R20 sizes, with multiple tire series represented, including g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, Street Pro III, and Drag Radial.
Brand choice should be treated as one part of a larger fitment decision rather than the whole answer. The car’s wheel diameter, front-versus-rear size, sidewall preference, and wheel-width compatibility still need to line up, especially on a staggered setup where a mismatched front or rear tire can complicate replacement planning.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Lexus LC500h?
Yes, modifications can affect tire fitment on a 2020 Lexus LC500h, especially because the car already uses a staggered setup with either 20-inch or 21-inch wheels. Aftermarket wheels, altered offsets, suspension changes, lowering, or body modifications can all change the space available for the correct front and rear tire sizes.
A car that has been modified should be checked at the wheel itself rather than assumed to still follow its original package. Wheel diameter, wheel width, and clearance at steering lock and suspension travel deserve attention before replacement tires are chosen, since the front and rear sizes need to work as a matched system.
What should I inspect before driving a 2020 Lexus LC500h on new tires?
Before driving a 2020 Lexus LC500h on new tires, inspect tire pressure, bead seating, valve condition, and the wheel for any visible damage. It is also wise to confirm that the front tires and rear tires are the correct staggered sizes for the car’s wheel package and that the directional or side-specific installation, if applicable, is correct.
A short recheck after the first miles is useful because new installations can reveal slow air loss or vibration that was not obvious in the shop. Attention should also go to alignment condition, suspension wear, and any sign of rubbing, since a low-profile staggered setup can react noticeably to wheel or chassis issues.
What should I check before a longer drive in a 2020 Lexus LC500h?
Before a longer drive in a 2020 Lexus LC500h, check inflation pressure, tread condition, and the sidewalls for cuts, cracking, bulges, or uneven wear. It is equally important to verify that the car still has a properly matched front-and-rear tire set for its 20-inch or 21-inch wheel package, since staggered fitment depends on keeping the correct sizes in place.
A grand touring car can cover distance quickly, so small problems become more important once the drive extends beyond routine local use. Looking over the wheels for impact damage, confirming there is no rubbing, and watching for any recent vibration or air-loss issue can help prevent an interrupted trip and protect the new tires.
