The 2020 Land Rover Trucks Defender 110 marked the return of the Defender name in a thoroughly modern form, blending the model’s long-standing expedition image with contemporary road manners, technology, and luxury-truck versatility. Buyers looking at one today are usually balancing everyday use with the rugged stance that defines the vehicle. Tire fitment on the 2020 Land Rover Trucks Defender 110 centers on four primary radial sizes: 255/70R18, 255/65R19, 255/60R20, and 275/45R22. That means the real choice is less about old bias-ply-versus-radial decisions and more about matching the correct size to the exact sub-model and wheel package. Getting that right preserves clearance, appearance, and the Defender’s intended character.
Which Tire Size Is Right for The 2020 Land Rover Trucks Defender 110
The 2020 Land Rover Trucks Defender 110 uses four primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. All of them are radial fitments, but they span 18-inch, 19-inch, 20-inch, and 22-inch rims. Before comparing tire choices, the first step is confirming which wheels are actually on the vehicle, since several sub-models share some sizes but not all four.
255/60R20 is a metric radial size in which 255 identifies the nominal section width in millimeters, 60 is the aspect ratio, R denotes radial construction, and 20 is the rim diameter in inches. On the 2020 Land Rover Trucks Defender 110, this size is one of the shared modern fitments used across the range. Its profile places it between the taller 18- and 19-inch combinations and the lower-profile 22-inch setup. This is the size to evaluate when the vehicle is equipped with 20-inch wheels and you want to stay with the corresponding factory-style wheel diameter.
255/65R19 follows the same modern metric radial format, with a 255-millimeter nominal section width, a 65-series profile, radial construction, and a 19-inch rim diameter. For the 2020 Land Rover Trucks Defender 110, it is one of the most broadly shared sizes across multiple sub-models. Its dimensions keep it closely aligned with the other primary Defender 110 fitments while pairing with a distinct wheel diameter. This is the size to focus on when the vehicle carries 19-inch wheels and you want to maintain that specific wheel-and-tire package.
255/70R18 is a metric radial size that uses a 255-millimeter nominal section width, a 70-series aspect ratio, radial construction, and an 18-inch rim. On the 2020 Land Rover Trucks Defender 110, this size applies to certain sub-model configurations rather than the full model line. Compared with the other primary sizes, it keeps a similar overall diameter while using the smallest rim diameter among the standard fitments shown here. It deserves a close look when selecting tires for an 18-inch wheel setup or confirming that a Base or S model still has its intended wheel diameter.
275/45R22 is a metric radial size with a 275-millimeter nominal section width, a 45-series profile, radial construction, and a 22-inch rim diameter. For the 2020 Land Rover Trucks Defender 110, this size is tied to specific upper-trim configurations rather than every sub-model. It is also the widest and lowest-profile primary fitment in the group, giving it a different visual presentation from the 18-, 19-, and 20-inch combinations. Choose this size only after confirming the vehicle has the corresponding 22-inch wheel package and the intended trim-specific setup.
2020 Land Rover Trucks Defender 110 Sub-Model Tires
Sub-model fitment on the 2020 Land Rover Trucks Defender 110 is not one-size-fits-all, even though several trims share overlapping tire sizes. Checking the exact sub-model matters because wheel diameter changes the correct tire size before brand, tread, or appearance choices ever come into play.

2020 Land Rover Trucks Defender 110 Base
The 2020 Land Rover Trucks Defender 110 Base uses a three-size fitment pattern built around 18-inch, 19-inch, or 20-inch radial wheel packages. Tire selection starts with confirming which of those wheel diameters is actually on the vehicle, then choosing within the corresponding modern metric size.
The 2020 Land Rover Trucks Defender 110 First Edition shares 19-inch and 20-inch radial fitments with other trims, but it can also use the 22-inch package. That makes wheel confirmation especially important before replacement, since the 275/45R22 option changes both rim diameter and tire profile.
The 2020 Land Rover Trucks Defender 110 HSE uses radial tire fitments tied to 19-inch, 20-inch, or 22-inch wheels. Replacing tires on an HSE means identifying the existing wheel package first, then matching the correct metric size rather than assuming every Defender 110 trim uses the same setup.
The 2020 Land Rover Trucks Defender 110 S follows the same general pattern as the Base model, with 18-inch, 19-inch, and 20-inch radial fitments. Buyers replacing tires on an S should verify whether the vehicle remains on its original wheel diameter or has been changed to a different package.
The 2020 Land Rover Trucks Defender 110 SE uses 19-inch and 20-inch radial sizes along with an available 22-inch fitment. The practical decision is matching the tire to the installed wheel package, since the wider, lower-profile 22-inch setup is distinct from the other SE tire choices.
The 2020 Land Rover Trucks Defender 110 X shares its fitment pattern with other upper trims, using radial tires on 19-inch, 20-inch, or 22-inch wheels. Getting the correct replacement starts with wheel confirmation, especially on vehicles that may have seen accessory-wheel or appearance-package changes.
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.
Frequently Asked Questions
Tire questions for the 2020 Land Rover Trucks Defender 110 usually come down to identifying the correct sub-model and wheel diameter first. The FAQs below focus on size meaning, rim fitment, trim-related differences, selection priorities, and the checks that matter before regular road use.
Tire Size & Fitment
What tire size fits a 2020 Land Rover Trucks Defender 110?
The 2020 Land Rover Trucks Defender 110 uses four primary radial tire sizes: 255/70R18, 255/65R19, 255/60R20, and 275/45R22. The correct size depends on the exact sub-model and wheel package, since not every Defender 110 trim uses every one of those sizes.
The key step is matching the tire to the wheel diameter currently on the vehicle. Several trims overlap on 19-inch and 20-inch fitments, while some use 18-inch or 22-inch combinations instead. Checking the existing wheel size before ordering replacement tires helps avoid choosing a metric size that belongs to a different Defender 110 setup.
What size rim does a 2020 Land Rover Trucks Defender 110 use?
A 2020 Land Rover Trucks Defender 110 can use 18-inch, 19-inch, 20-inch, or 22-inch rims, depending on the tire size and sub-model configuration. Those rim diameters correspond to 255/70R18, 255/65R19, 255/60R20, and 275/45R22 radial tires.
Rim diameter is the first fitment detail to confirm because each tire size is built around a specific wheel. A Defender 110 on 20-inch wheels needs a 20-inch tire size, not simply a tire with a similar overall height. Looking at the sidewall size marking or measuring the wheel before replacement is the safest way to keep the selection on track.
Do all 2020 Land Rover Trucks Defender 110 sub-models use the same tire size?
No, the 2020 Land Rover Trucks Defender 110 sub-models do not all use the same tire size. Base and S configurations can use 255/70R18, 255/65R19, or 255/60R20, while First Edition, HSE, SE, and X trims use 255/65R19, 255/60R20, or 275/45R22.
That overlap can make replacement seem simpler than it is, especially because several trims share two of the same sizes. The deciding factor is the exact sub-model and the wheel package actually installed on the vehicle today. A quick check of both trim level and wheel diameter prevents mixing an 18-inch or 22-inch fitment into the wrong Defender 110 configuration.
Choosing the Right Tire
What should I consider when choosing a 2020 Land Rover Trucks Defender 110 tire?
Start with the correct size for the specific Defender 110 sub-model and wheel diameter, since this vehicle uses four different radial fitments. The choice is then about staying with the proper metric size and matching it to the vehicle’s current 18-inch, 19-inch, 20-inch, or 22-inch wheel setup.
After size is confirmed, consider how the vehicle is used and whether it still carries its original wheel package. A Defender 110 kept stock should remain close to its intended tire dimensions, while one with accessory wheels needs extra scrutiny for clearance and wheel compatibility. Tire selection makes more sense once those fitment basics are settled first.
How do I choose between the available 2020 Land Rover Trucks Defender 110 tire sizes?
The available sizes are not interchangeable choices for the same wheel. 255/70R18, 255/65R19, 255/60R20, and 275/45R22 each correspond to a different rim diameter, and the correct one depends on the installed wheel package and trim-specific setup of the 2020 Land Rover Trucks Defender 110.
Think of the decision as wheel-first rather than tire-first. The vehicle may share overall tire proportions across several sizes, but the sidewall marking must still match the actual rim diameter. Checking the current tires, the wheel itself, and any prior modifications helps narrow the choice quickly and keeps the replacement process centered on fitment rather than guesswork.
What rim-fitment details should I compare when choosing 2020 Land Rover Trucks Defender 110 tires?
The most important rim-fitment detail is diameter, because the 2020 Land Rover Trucks Defender 110 uses 18-inch, 19-inch, 20-inch, and 22-inch wheel-based tire sizes. The tire’s final number must match the wheel exactly, whether that means 18, 19, 20, or 22 inches.
It also helps to confirm that the wheel package on the vehicle has not changed from its original trim setup. Aftermarket wheels, appearance upgrades, or seasonal wheel sets can change the correct tire size even within the same sub-model. Looking at the existing sidewall marking and checking wheel dimensions directly is the most practical way to avoid a mismatch.
Restoration & Appearance
Does correct tire fitment matter for a 2020 Land Rover Trucks Defender 110 restoration or preservation project?
Yes, correct tire fitment still matters on a 2020 Land Rover Trucks Defender 110, even though it is a modern vehicle. The right tire size helps preserve the intended stance, wheel-to-tire proportion, and trim-specific appearance, whether the vehicle is being kept original in character or simply maintained carefully over time.
A preservation-minded owner should match the tire to the wheel diameter and sub-model rather than choosing by appearance alone. An 18-inch setup presents the truck differently than a 22-inch package, and those visual differences are part of the vehicle’s overall identity. Exact originality questions are best confirmed against vehicle records, window-sticker details, or marque-specific references.
How does tire size affect the appearance of a 2020 Land Rover Trucks Defender 110?
Tire size affects both stance and sidewall proportion on the 2020 Land Rover Trucks Defender 110. The 255/70R18 fitment uses more sidewall on a smaller wheel, while 275/45R22 places a wider, lower-profile tire on a larger rim, creating a noticeably different visual balance.
That matters if the goal is to keep the Defender 110 looking consistent with its original wheel package rather than chasing a different style direction. Replacing tires in the same size preserves the relationship between wheel diameter and sidewall height that defines the truck’s look. Appearance should always be evaluated alongside proper wheel match and clearance, not separately from them.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Land Rover Trucks Defender 110?
Yes, modifications can affect tire fitment on a 2020 Land Rover Trucks Defender 110. Wheel changes, suspension alterations, lift or lowering work, and body or fender modifications can all change the clearance and dimensional assumptions behind the original 255/70R18, 255/65R19, 255/60R20, or 275/45R22 tire fitments.
A Defender 110 that has been altered should be checked as it sits today, not just by trim-level expectations. Wheel diameter, wheel width, and the space available at full steering lock all matter once changes have been made. Taking a close look before replacement helps keep the next tire choice aligned with the actual vehicle rather than the standard catalog pattern.
What should I inspect before driving a 2020 Land Rover Trucks Defender 110 on new tires?
Before regular road use, inspect the tire size marking, inflation pressure, bead seating, and visible clearance around the wheelhouse and suspension. A 2020 Land Rover Trucks Defender 110 should also be checked for even spacing during steering movement, especially if the vehicle has a larger wheel package or any aftermarket changes.
It is also wise to verify that the wheels are the correct diameter for the installed tires and that there are no signs of rubbing under load or at full lock. A short, careful test drive can reveal vibration, contact, or handling issues early. Catching those details before longer trips helps protect both the tires and the vehicle.
How often should tires on a 2020 Land Rover Trucks Defender 110 be inspected?
Tires on a 2020 Land Rover Trucks Defender 110 should be inspected regularly, not just when they look worn. Pressure, tread condition, cuts, punctures, sidewall damage, and irregular wear deserve routine attention, especially on vehicles that alternate between daily driving, towing, or long idle periods.
Inspection becomes even more important if the Defender 110 uses different seasonal wheel sets or has been fitted with nonstandard wheels. Looking over the tires before longer drives and after off-road or rough-road use helps catch air loss and clearance problems early. Consistent inspection is one of the simplest ways to preserve ride quality and fitment confidence.
