The 2015 Land Rover Trucks LR4 sits in the later era of the Discovery line, blending full-size utility, upscale comfort, and the tall, squared-off design that made it appealing to owners who wanted a true SUV rather than a crossover. Its tire fitment is straightforward in construction but not in wheel choice, because this LR4 uses radial tires in two sizes: 255/55R19 and 255/50R20. Both sizes carry the same overall diameter family, but they match different rim diameters. That makes the real decision less about changing tire type and more about confirming which wheel package is on the vehicle before comparing tread design, road manners, and overall replacement priorities.
Which Tire Size Is Right for The 2015 Land Rover Trucks LR4
The 2015 Land Rover Trucks LR4 uses two primary tire sizes, and the first step is confirming whether the vehicle has 19-inch or 20-inch wheels. Both sizes are radial metric fitments and both appear across Base, HSE, and HSE Lux models, so wheel diameter matters more than sub-model name. Once the wheel package is confirmed, the decision becomes choosing the right replacement tire within that size and intended use.
A 255/50R20 tire uses a 255-millimeter nominal section width, a 50-series aspect ratio, radial construction, and a 20-inch rim diameter. On the 2015 Land Rover Trucks LR4, this is one of the two primary radial fitments and it belongs only on vehicles equipped with 20-inch wheels. The lower-profile side of this metric size gives it a different visual proportion than the 19-inch alternative even though both share the same overall diameter. This size is the right place to start when your LR4 already wears 20-inch wheels and you want to stay with the original wheel diameter.
A 255/55R19 tire uses the same 255-millimeter nominal section width as the 20-inch option, but it pairs that width with a 55-series profile and a 19-inch rim diameter. For the 2015 Land Rover Trucks LR4, this is the companion primary radial fitment for vehicles equipped with 19-inch wheels. Its overall diameter matches the 20-inch fitment closely, but the tire and wheel relationship is different because the rim diameter changes. This size should be chosen when the LR4 has 19-inch wheels and the goal is to keep the correct wheel-to-tire combination.
Tire fitment on the 2015 Land Rover Trucks LR4 is consistent across the covered sub-models, but it still requires checking the actual wheel diameter on the vehicle. Base, HSE, and HSE Lux models can use either primary size, so the sub-model alone does not settle the tire choice.

2015 Land Rover Trucks LR4 Base
The 2015 Land Rover Trucks LR4 Base uses the same two primary radial tire sizes found elsewhere in the LR4 range. Tire selection starts with confirming whether the vehicle has 19-inch or 20-inch wheels, then choosing a replacement tire that matches that wheel setup and intended use.
The 2015 Land Rover Trucks LR4 HSE also falls within the same two-size fitment pattern, so there is no unique HSE-only tire size to assume. The practical step is checking the wheel diameter already on the vehicle before selecting between the 255/55R19 and 255/50R20 radial fitments.
The 2015 Land Rover Trucks LR4 HSE Lux shares the same tire-size choices as the other LR4 sub-models in this year range. That means the key detail is the actual wheel package on the vehicle, not the trim badge, before comparing replacement tires in the correct radial size.
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
Questions about 2015 Land Rover Trucks LR4 tires usually come down to the correct size, whether the vehicle has 19-inch or 20-inch wheels, and how to choose the right radial replacement for the way the SUV is actually used.
Tire Size & Fitment
What tire size fits a 2015 Land Rover Trucks LR4?
The 2015 Land Rover Trucks LR4 uses two primary tire sizes: 255/55R19 and 255/50R20. Both are radial metric fitments, and both appear across Base, HSE, and HSE Lux models rather than being tied to a single trim level.
The important step is confirming which wheel diameter is actually on the vehicle before choosing a tire. A 19-inch wheel requires 255/55R19, while a 20-inch wheel requires 255/50R20. Since both sizes share the same overall diameter family, the deciding factor is the wheel package, not simply the trim badge on the LR4.
What size rim does a 2015 Land Rover Trucks LR4 use?
A 2015 Land Rover Trucks LR4 uses either a 19-inch or 20-inch rim, depending on the wheel package on the vehicle. The 255/55R19 tire matches a 19-inch rim, and the 255/50R20 tire matches a 20-inch rim.
Checking the actual wheel diameter matters more than guessing from the model name, because Base, HSE, and HSE Lux can all be found with either primary tire size. Looking at the tire sidewall or measuring the wheel is the fastest way to confirm fitment before ordering replacements or comparing tire options.
Do all 2015 Land Rover Trucks LR4 sub-models use the same tire size?
Base, HSE, and HSE Lux versions of the 2015 Land Rover Trucks LR4 share the same two tire-size possibilities: 255/55R19 and 255/50R20. In other words, the sub-model range is consistent, but each individual vehicle still uses only the size that matches its wheel diameter.
That means trim level alone is not enough to choose a tire. The practical check is whether the LR4 has 19-inch or 20-inch wheels today, especially if wheels have ever been changed. Once that is confirmed, tire selection becomes much simpler because both fitments are standard radial metric sizes.
Choosing the Right Tire
What should I consider when choosing a tire for a 2015 Land Rover Trucks LR4?
Start with the correct size for the wheel already on the vehicle: 255/55R19 for 19-inch rims or 255/50R20 for 20-inch rims. The 2015 Land Rover Trucks LR4 uses radial metric tires, so the main selection factors are the exact size, the wheel diameter, and how the vehicle is driven.
A road-focused LR4 may lead you toward a different replacement than one used for mixed weather or heavier utility driving. It is also worth checking the current wheel setup carefully if the vehicle has ever been modified, because the right replacement begins with matching the tire to the wheel rather than choosing by trim name alone.
How do I choose between the available 255/55R19 and 255/50R20 tires for a 2015 Land Rover Trucks LR4?
You do not choose between those sizes based on preference alone, because each one belongs to a different wheel diameter. A 255/55R19 is for a 19-inch wheel, while a 255/50R20 is for a 20-inch wheel, even though both share the same overall diameter family.
Once the wheel size is confirmed, compare tires within that one correct size. That keeps the focus on replacement priorities such as day-to-day road use, ride expectations, and the condition of the existing wheels. Treating the two sizes as interchangeable choices can lead to an immediate mismatch between tire bead and rim diameter.
What should I compare before replacing tires on a 2015 Land Rover Trucks LR4?
The key comparisons are the exact tire size on the vehicle now, the wheel diameter, and whether all four wheels match. On a 2015 Land Rover Trucks LR4, that usually means verifying 255/55R19 versus 255/50R20 before looking at any replacement tire details.
It also helps to inspect whether the LR4 still has its original wheel setup or has moved to aftermarket wheels. Once size and wheel diameter are confirmed, compare the replacement tire's intended use and fitment details within that correct size. That approach avoids confusion between the two primary LR4 fitments and keeps the selection process grounded.
Restoration & Appearance
Does correct tire fitment matter for a 2015 Land Rover Trucks LR4 restoration?
Yes, correct tire fitment still matters on a 2015 Land Rover Trucks LR4, even though it is a newer vehicle than traditional collector-era models. The right size preserves the intended relationship between the tire, the wheel, and the vehicle's stance, with 255/55R19 and 255/50R20 tied to different rim diameters.
Appearance is part of that decision, but fitment comes first. An LR4 being returned to a more original-style presentation should keep the wheel diameter and tire size in step rather than treating the two sizes as cosmetic alternatives. If originality matters closely, compare the current setup to vehicle history, photos, or marque-specific references before changing wheels.
Which tire should I choose for a period-style 2015 Land Rover Trucks LR4?
A period-style approach for a 2015 Land Rover Trucks LR4 starts by staying with the wheel diameter and tire size the vehicle is already built around, either 255/55R19 or 255/50R20. Since both are modern radial metric sizes, the visual character comes more from preserving the proper wheel-and-tire proportion than from changing construction type.
That makes wheel confirmation the first step before comparing replacement tires. A 19-inch setup and a 20-inch setup can both look right on an LR4, but they are not the same fitment. Keeping the correct size on the correct wheel usually does more for the vehicle's overall presentation than trying to force a different diameter combination.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 Land Rover Trucks LR4?
Yes, modifications can affect tire fitment on a 2015 Land Rover Trucks LR4, especially if the vehicle has aftermarket wheels, suspension changes, or altered ride height. Even when the tire size looks close to the original fitment, those changes can affect clearance at the fenders, suspension, and steering components.
That is why the current setup should be checked before replacing tires. An LR4 still using its original wheel diameter will usually stay within the normal 255/55R19 or 255/50R20 fitment path, but a modified vehicle deserves a closer look at wheel size, width, and clearance before any new tire is selected.
What should I inspect before driving a 2015 Land Rover Trucks LR4 on new tires?
Before driving a 2015 Land Rover Trucks LR4 on new tires, inspect the wheels for damage, confirm the tire size matches the wheel diameter, and check inflation pressure carefully. It is also wise to look over the suspension and steering components so the new tires are not being introduced to an already uneven or unstable setup.
A brief clearance check at full steering lock is worthwhile, particularly if the LR4 has different wheels than it left the factory with. After the first miles, recheck pressure and look for any signs of rubbing or unusual wear. Catching those issues early helps protect both the new tires and the vehicle's handling.
How often should tires on a 2015 Land Rover Trucks LR4 be inspected?
Tires on a 2015 Land Rover Trucks LR4 should be inspected regularly, not just when tread looks low. Pressure, tread wear, cuts, bulges, cracking, and signs of air loss all deserve attention, especially on an SUV that may see mixed road conditions or spend periods parked between longer drives.
A routine visual check before trips and a closer inspection at service intervals is a sensible habit. Vehicles that sit for longer periods can develop age-related issues that are easy to miss at a glance, so condition matters just as much as tread depth. Staying ahead of those checks helps keep the LR4 predictable and road-ready.
