The 2021 Land Rover Trucks Defender 110 brought the Defender name into a thoroughly modern SUV format while keeping the upright stance and expedition-minded character that make the model so distinctive. For many owners, that means balancing contemporary road manners with the rugged look expected from a Defender. Tire fitment on the 2021 Land Rover Trucks Defender 110 centers on radial construction, but the exact size depends on the sub-model and wheel package, with 18-, 19-, 20-, and 22-inch rim diameters all in the mix. That makes the real decision less about bias-ply versus radial and more about confirming the correct wheel size, profile, and overall presentation before choosing a replacement.
Which Tire Size Is Right for The 2021 Land Rover Trucks Defender 110
The 2021 Land Rover Trucks Defender 110 uses four primary tire sizes, and they vary by sub-model and wheel diameter rather than by tire construction. Every fitment here is a radial, so the first step is confirming the exact sub-model and the actual wheel diameter on the vehicle before selecting a tire. That matters especially on Defender 110s that may have been optioned differently or changed after delivery.
Fit(s): Base, S, SE, X, X-Dynamic HSE, and X-Dynamic SE
Construction: Radial|Rim: 20 in
255/60R20 is a modern metric radial size in which 255 identifies nominal section width in millimeters, 60 is the aspect ratio, R denotes radial construction, and 20 is the rim diameter in inches. On the 2021 Land Rover Trucks Defender 110, this size represents one of the mainstream factory-style radial fitments used across several sub-models. Its dimensions place it in the core Defender 110 replacement range, making it a practical reference point for owners who want to stay with the wheel diameter already on the vehicle. Confirming the wheel itself remains the key step before moving ahead.
Fit(s): Base, S, SE, X, X-Dynamic HSE, and X-Dynamic SE
Construction: Radial|Rim: 19 in
255/65R19 follows the same metric radial format: 255 millimeters of nominal section width, a 65-series profile, radial construction, and a 19-inch rim diameter. For the 2021 Land Rover Trucks Defender 110, this is another primary fitment used on multiple sub-models, so it often comes up when replacing tires on vehicles that retain their original 19-inch wheels. The similar section width to the 18- and 20-inch options means the main distinction is wheel diameter and sidewall profile rather than a completely different tire category. Matching the tire to the installed wheel package is essential.
255/70R18 uses a 255-millimeter nominal section width, a 70-series aspect ratio, radial construction, and an 18-inch rim diameter. On the 2021 Land Rover Trucks Defender 110, this size appears on selected sub-models and sits at the smaller rim end of the primary fitment range. It is especially important to distinguish from the 19- and 20-inch options because the tire may look broadly similar at a glance while requiring a different wheel diameter. Owners considering replacement should verify both the sub-model and the actual wheels on the vehicle, particularly if a previous owner changed them.
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. On the 2021 Land Rover Trucks Defender 110, it serves a distinct role by pairing a wider section width with the largest wheel diameter used among the primary fitments. That makes it less about broad interchangeability and more about preserving the correct relationship between tire, wheel, and vehicle stance on the specific sub-models that use it. Wheel confirmation should come before any comparison with the smaller-diameter setups.
2021 Land Rover Trucks Defender 110 Sub-Model Tires
Tire fitment for the 2021 Land Rover Trucks Defender 110 is not uniform across all covered sub-models. Several trims share some sizes, but the exact choice still depends on confirming the sub-model and the wheel diameter currently installed on the vehicle.

2021 Land Rover Trucks Defender 110 Base
The 2021 Land Rover Trucks Defender 110 Base uses three primary radial sizes, all centered on 18-, 19-, and 20-inch wheel packages rather than the 22-inch setup. Tire selection starts with confirming which wheel diameter the vehicle has, then choosing a replacement that matches that installed configuration.
The 2021 Land Rover Trucks Defender 110 S has the broadest fitment spread here, covering all four primary radial sizes from 18-inch through 22-inch wheel packages. That makes wheel verification especially important before replacement, since the correct tire depends on the specific setup on the vehicle rather than the trim name alone.
The 2021 Land Rover Trucks Defender 110 SE uses radial fitments tied to 19-, 20-, and 22-inch wheel diameters. Choosing the right tire is mainly a matter of matching the installed wheel package and preserving the intended profile, since these sizes are not interchangeable simply because they belong to the same model.
The 2021 Land Rover Trucks Defender 110 X shares a three-size radial fitment pattern built around 19-, 20-, and 22-inch wheels. Owners should confirm the exact wheel diameter on the vehicle first, then compare replacement tires within that size rather than assuming all Defender 110 X models carry the same setup.
The 2021 Land Rover Trucks Defender 110 X-Dynamic HSE uses three primary radial sizes and does not share the 18-inch option found on some other Defender 110 configurations. Tire selection is most straightforward once the actual wheel diameter is confirmed, especially on vehicles that may have received wheel changes after purchase.
The 2021 Land Rover Trucks Defender 110 X-Dynamic SE also uses three radial fitments associated with 19-, 20-, and 22-inch wheels. The practical step is to verify the installed wheel package first, since that determines the correct tire size far more clearly than trim name alone.
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
Common questions for the 2021 Land Rover Trucks Defender 110 usually center on the correct tire size for each sub-model, wheel diameter differences, and how to choose among the available radial fitments without creating clearance or setup issues.
Tire Size & Fitment
What tire size fits a 2021 Land Rover Trucks Defender 110?
The 2021 Land Rover Trucks Defender 110 uses four primary tire sizes: 255/70R18, 255/65R19, 255/60R20, and 275/45R22. All of them are radial sizes, but they do not apply uniformly across every sub-model because fitment changes with trim and wheel package.
The most important next step is identifying the exact sub-model and confirming the wheel diameter currently on the vehicle. A Defender 110 S can use all four sizes, while other sub-models use only certain combinations, so replacement should always start with the installed wheel and tire setup rather than the model name alone.
What size rim does a 2021 Land Rover Trucks Defender 110 use?
A 2021 Land Rover Trucks Defender 110 can use 18-, 19-, 20-, or 22-inch rims, depending on sub-model and wheel package. Those rim diameters correspond to the primary tire sizes 255/70R18, 255/65R19, 255/60R20, and 275/45R22.
Rim diameter should be confirmed before any tire purchase because the tire must match the wheel exactly. Even though several Defender 110 sizes are close in overall diameter, they are built for different wheel diameters and cannot be selected by appearance alone, especially on vehicles that may have had wheel changes or upgrades.
Do all 2021 Land Rover Trucks Defender 110 sub-models use the same tire size?
No, the covered 2021 Land Rover Trucks Defender 110 sub-models do not all use the same tire size. The Base uses 255/70R18, 255/65R19, and 255/60R20, while the S adds 275/45R22, and several upper trims use 255/65R19, 255/60R20, and 275/45R22.
That variation means the trim badge alone is helpful, but the wheel diameter on the vehicle is still the deciding detail. Checking the current tire sidewall and the wheel itself is the safest way to narrow the fitment, particularly if the Defender 110 has been reconfigured with a different factory-style wheel package.
Choosing the Right Tire
What should I consider when choosing a tire for a 2021 Land Rover Trucks Defender 110?
Start with the correct primary size for the specific Defender 110 sub-model and wheel diameter: 255/70R18, 255/65R19, 255/60R20, or 275/45R22. Since every fitment here is radial, the main decision is matching the installed wheel package and maintaining the intended size rather than choosing between different vintage tire constructions.
After the size is confirmed, compare how the vehicle is used and whether the current wheel setup is original to the vehicle or a later change. A Defender 110 that has been modified with different wheels, suspension changes, or altered ride height should have clearance and wheel compatibility checked before moving away from its present tire specification.
How do I choose between the available 2021 Land Rover Trucks Defender 110 tire sizes?
The available sizes are not alternatives to mix and match at will; they correspond to different wheel diameters and sub-model configurations. Choosing between 255/70R18, 255/65R19, 255/60R20, and 275/45R22 begins with confirming which exact size is already fitted to the Defender 110.
Once that is established, the right comparison is within the same size, not across all four sizes. Looking at the sidewall marking on the current tire is usually the quickest check, and it is worth confirming that the wheels are the intended diameter if the vehicle was purchased used or has seen any aftermarket wheel changes.
What rim-fitment details matter when choosing 2021 Land Rover Trucks Defender 110 tires?
Rim diameter is the first rim-fitment detail that matters on the 2021 Land Rover Trucks Defender 110 because this model uses 18-, 19-, 20-, and 22-inch wheel setups. The tire size must match that diameter exactly, whether the vehicle uses 255/70R18, 255/65R19, 255/60R20, or 275/45R22.
Wheel condition and actual setup matter as well, especially on a used Defender 110. A replacement tire should be chosen only after confirming the installed wheel size and making sure there have not been changes to wheel width, offset, suspension height, or surrounding clearance that could affect how the tire sits and operates.
Restoration & Appearance
Does correct tire fitment matter for a 2021 Land Rover Trucks Defender 110 restoration or preservation-minded build?
Yes, correct tire fitment matters because the 2021 Land Rover Trucks Defender 110 uses several different wheel-and-tire combinations across its sub-model range. Staying with the proper size for the vehicle's actual wheel package helps preserve the intended stance, sidewall proportion, and overall presentation.
On a newer collector-oriented vehicle, appearance usually comes down to keeping the relationship between wheel diameter and tire profile in balance. Owners pursuing a preservation-minded result should verify the current setup carefully and compare it with model-specific references or original vehicle documentation before changing to a different size simply for looks.
How does tire size affect the appearance of a 2021 Land Rover Trucks Defender 110?
Tire size has a visible effect on the 2021 Land Rover Trucks Defender 110 because the model spans 18-, 19-, 20-, and 22-inch wheel packages. A 255/70R18 presents a taller-sidewall look than a 275/45R22, even though both belong to the same vehicle family.
That visual difference is one reason size changes should not be treated casually. Owners who want to preserve the intended character of their Defender 110 should confirm the original wheel package on the specific sub-model and choose a replacement size that maintains the vehicle's proper proportion rather than chasing a different look without checking fitment first.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2021 Land Rover Trucks Defender 110?
Yes, modifications can affect tire fitment on a 2021 Land Rover Trucks Defender 110 even when the tire size appears close to one of the original options. Changes such as aftermarket wheels, altered wheel offset, suspension lifts or drops, and body modifications can all influence clearance and how the tire sits under the vehicle.
That is why a Defender 110 with non-original wheels or chassis changes should be checked carefully before replacement. Tire selection should account for actual wheel diameter, surrounding clearance at full steering lock, and the space available through suspension movement rather than relying only on what fits an unmodified vehicle.
What should I inspect before driving a 2021 Land Rover Trucks Defender 110 on new tires?
Before driving a 2021 Land Rover Trucks Defender 110 on new tires, confirm that the installed size matches the wheel diameter and that each tire is seated and inflated properly. It is also smart to inspect the wheels for damage and verify that there is no rubbing at normal ride height or during steering movement.
A short initial check drive should be followed by another inspection for air loss, unusual contact marks, or vibration. Tire pressure, lug security, and visible clearance around suspension and fender areas are worth rechecking, especially if the Defender 110 has different wheels than it originally carried or has seen suspension changes.
How often should tires on a 2021 Land Rover Trucks Defender 110 be inspected?
Tires on a 2021 Land Rover Trucks Defender 110 should be inspected regularly, not just when replacement is due. Routine checks should include pressure, tread condition, cuts, bulges, irregular wear, and any visible cracking or damage around the sidewall and bead area.
Inspection becomes even more important on vehicles that are driven infrequently or used in mixed on-road and off-road conditions. A Defender 110 that sits for long periods can still develop age-related issues, while one with wheel or suspension changes deserves closer attention for uneven wear or clearance problems that might not be obvious at first glance.
