The 1999 Land Rover Trucks Range Rover belongs to the P38 era, a generation known for blending traditional Range Rover luxury with genuine four-wheel-drive capability. Buyers are often balancing two priorities with this model: preserving its correct stance and keeping the vehicle usable for modern road driving. Tire fitment on the 1999 Land Rover Trucks Range Rover centers on two radial sizes, 255/65R16 and 255/55R18, depending on the sub-model and wheel package. That means the key decision is not just brand or tread style, but first confirming whether the vehicle is on 16-inch or 18-inch wheels. Once that is settled, tire selection becomes a matter of matching the correct size to the vehicle's trim, wheel setup, and intended use.
Which Tire Size Is Right for The 1999 Land Rover Trucks Range Rover
Two tire sizes apply to the 1999 Land Rover Trucks Range Rover, and the correct choice depends on the specific sub-model and wheel diameter. The first thing to confirm is whether the vehicle uses a 16-inch or 18-inch rim, since the two sizes are not interchangeable simply because they have similar overall dimensions. Once wheel diameter and sub-model are confirmed, the decision becomes choosing the right radial tire within that fitment.
255/55R18 is also a metric radial size, with the same 255-millimeter nominal width but a lower 55-series profile mounted on an 18-inch rim. For the 1999 Range Rover, this size belongs to the sub-models equipped with 18-inch wheels, so it should be selected by configuration rather than by appearance alone. Its lower-profile format gives the vehicle a different visual balance than the 16-inch fitment while remaining close in overall diameter. Before choosing this size, verify the actual wheel diameter on the vehicle and check that any prior wheel changes have not altered the intended fitment.
1999 Land Rover Trucks Range Rover Sub-Model Tires
Sub-model fitment matters on the 1999 Land Rover Trucks Range Rover because tire size changes with wheel diameter. Some versions use the 16-inch radial fitment, while others use the 18-inch radial fitment, so identifying the exact sub-model is the first step before comparing tires.

1999 Land Rover Trucks Range Rover Base
The 1999 Land Rover Trucks Range Rover Base uses the 255/65R16 radial size on a 16-inch wheel. Tire selection for this version should stay focused on the correct 16-inch fitment and on confirming that the vehicle has not been changed to a different wheel package over time.
The 1999 Land Rover Trucks Range Rover Callaway uses the 255/55R18 radial size with an 18-inch wheel. That makes wheel-diameter confirmation especially important before replacing tires, particularly on vehicles that may have seen aftermarket wheel changes or prior fitment substitutions.
The 1999 Land Rover Trucks Range Rover HSE uses the 255/55R18 radial fitment. Buyers looking at this sub-model should begin by confirming that the current wheels are still 18-inch units, then compare tire options within that size based on road use, appearance, and overall setup.
The 1999 Land Rover Trucks Range Rover S also uses the 255/55R18 radial size. For this version, the practical tire decision centers on staying with the proper 18-inch fitment and making sure wheel and suspension changes have not affected clearance or altered the vehicle's intended setup.
The 1999 Land Rover Trucks Range Rover SE uses the 255/65R16 radial size. That keeps tire selection straightforward as long as the vehicle remains on its 16-inch wheels, but wheel diameter should still be checked before ordering replacements on an older SUV that may have been modified.
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
These FAQs focus on the exact tire sizes used on the 1999 Land Rover Trucks Range Rover, how fitment changes by sub-model, and what to verify before replacing tires on a vehicle that may no longer be on its original wheels.
Tire Size & Fitment
What tire size fits a 1999 Land Rover Trucks Range Rover?
The 1999 Land Rover Trucks Range Rover uses either 255/65R16 or 255/55R18 radial tires. The correct size depends on the sub-model, with Base and SE using 255/65R16, while Callaway, HSE, and S use 255/55R18.
That makes sub-model and wheel confirmation more important than simply matching the vehicle year and model name. Many older Range Rovers have seen wheel changes over time, so checking the actual tire sidewall and wheel diameter on the vehicle is the safest starting point before selecting replacement tires.
What size rim does a 1999 Land Rover Trucks Range Rover use?
A 1999 Land Rover Trucks Range Rover uses either a 16-inch or 18-inch rim, depending on the sub-model. The 255/65R16 fitment uses a 16-inch rim, and the 255/55R18 fitment uses an 18-inch rim.
Rim diameter should be confirmed before anything else because these two tire sizes are built for different wheel diameters. Even though their overall tire dimensions are very close, a 16-inch tire cannot be mounted on an 18-inch wheel, and an 18-inch tire cannot be mounted on a 16-inch wheel.
Do all 1999 Land Rover Trucks Range Rover sub-models use the same tire size?
No, the 1999 Land Rover Trucks Range Rover does not use one tire size across every sub-model. Base and SE use 255/65R16, while Callaway, HSE, and S use 255/55R18.
That difference is tied to wheel diameter, so the sub-model name is a useful guide but not the only thing to verify. On a used or restored vehicle, the wheel package may have been changed, so checking both the sub-model and the actual wheel on the truck helps prevent ordering the wrong size.
Choosing the Right Tire
What should I consider when choosing a tire for a 1999 Land Rover Trucks Range Rover?
Start with the correct size for the exact sub-model and wheel diameter: 255/65R16 for Base and SE, or 255/55R18 for Callaway, HSE, and S. Both fitments are radial, so the first decision is not construction type but making sure the tire matches the wheel actually on the vehicle.
After size is confirmed, compare tires based on how the Range Rover is used. A mostly road-driven truck may call for a different tread character than one that still sees rougher conditions, and any replacement should also be checked for clearance if the vehicle has aftermarket wheels or suspension changes.
How do I choose between the available 255/65R16 and 255/55R18 tires for a 1999 Land Rover Trucks Range Rover?
The choice between 255/65R16 and 255/55R18 is not a matter of preference on the 1999 Land Rover Trucks Range Rover; it is a matter of correct fitment. Each size belongs to particular sub-models and wheel diameters, so the vehicle's actual wheel setup determines which tire belongs on it.
Once the right size is established, compare tires within that fitment by intended use, tread style, and how closely you want to preserve the truck's original visual stance. Similar overall diameter does not make the two sizes interchangeable, so wheel diameter should always decide the direction first.
What tire size should I use for my 1999 Land Rover Trucks Range Rover sub-model?
Use 255/65R16 on the 1999 Land Rover Trucks Range Rover Base and SE. Use 255/55R18 on the Callaway, HSE, and S. Those are the primary radial sizes tied to the covered sub-models.
That answer should still be checked against the vehicle as it sits today, especially on an older luxury SUV that may have passed through several owners. Reading the sidewall and confirming wheel diameter on the truck helps ensure the replacement tire matches the current configuration rather than an earlier setup.
Restoration & Appearance
Which tire should I choose for a period-style 1999 Land Rover Trucks Range Rover?
A period-style choice for a 1999 Land Rover Trucks Range Rover starts with using the correct size for the sub-model and wheel diameter. That means 255/65R16 for Base and SE, or 255/55R18 for Callaway, HSE, and S, while staying with a radial construction that matches the original fitment type.
Appearance on a P38 Range Rover is closely tied to wheel size and sidewall profile, so the wrong tire size can change the vehicle's stance even if it mounts successfully. Buyers focused on restoration presentation should confirm the truck's actual wheel package before choosing a replacement that supports the intended look.
Does correct tire fitment matter for a 1999 Land Rover Trucks Range Rover restoration?
Yes, correct tire fitment matters because the 1999 Land Rover Trucks Range Rover used more than one size depending on sub-model. Selecting the proper 16-inch or 18-inch fitment helps preserve the vehicle's intended proportions and avoids forcing a visual mismatch between the tire and wheel package.
On a restoration-oriented truck, fitment affects more than appearance alone. The wrong size can complicate clearance, alter how full the wheel opening looks, and make the vehicle appear inconsistent with its original configuration, so wheel diameter and the exact sub-model should be confirmed before final tire selection.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1999 Land Rover Trucks Range Rover?
Yes, modifications can affect tire fitment on a 1999 Land Rover Trucks Range Rover. Aftermarket wheels, suspension changes, altered ride height, or body modifications can all change the space available around a 255/65R16 or 255/55R18 tire, even when the size itself is correct for the original sub-model.
A Range Rover that has been lifted, lowered, or fitted with different wheels should be checked for wheel diameter, wheel width, steering clearance, and fender clearance before replacing tires. Matching the original size alone is not enough when the vehicle's hardware has changed from its intended configuration.
What should I inspect before driving a 1999 Land Rover Trucks Range Rover on new tires?
Before road use, inspect the wheel diameter, confirm the new tires match the correct size for the sub-model, and check that the tires seat properly on the wheels. It is also wise to look over valve stems, wheel condition, visible suspension wear, and the clearances at full steering lock.
An older Range Rover should also be checked for proper tire pressure, uneven wear signs, rubbing marks, and any vibration once it is back on the road. A short test drive followed by a second visual inspection can help catch clearance or setup issues before they turn into larger problems.
How often should tires on a 1999 Land Rover Trucks Range Rover be inspected?
Tires on a 1999 Land Rover Trucks Range Rover should be inspected regularly, especially if the truck is driven infrequently or stored for part of the year. Beyond normal tread checks, owners should watch for sidewall cracking, bulges, cuts, punctures, uneven wear, and gradual air loss.
Collector and lightly used SUVs can age tires long before the tread is gone, so condition matters as much as mileage. A visual check before longer drives and routine pressure checks during storage periods help catch problems early, particularly on vehicles that may sit for extended periods between outings.
