The 2000 Land Rover Trucks Discovery sits at the point where Land Rover’s family-sized SUV combined traditional off-road character with a more modern road-going setup. Discovery buyers often value these trucks for their blend of utility, upright design, and genuine all-terrain heritage. For this exact model year, tire selection starts with two radial fitments: 255/65R16 and 255/55R18. That means the real decision is less about old bias-ply versus radial construction and more about confirming which wheel diameter is on the truck before choosing a replacement tire. Once that is settled, the focus shifts to maintaining the right overall stance, proper wheel compatibility, and clearance on a stock or modified Discovery.
Which Tire Size Is Right for The 2000 Land Rover Trucks Discovery
The 2000 Land Rover Trucks Discovery uses two primary tire sizes, and both are radial fitments with nearly the same overall diameter. The important difference is wheel diameter: one size is built for a 16-inch rim and the other for an 18-inch rim. Before choosing a tire, confirm which wheels are actually on the truck, since that determines the correct size more than anything else.
255/55R18 is a metric radial size in which 255 is the nominal section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 18 is the rim diameter in inches. On the 2000 Land Rover Trucks Discovery, this size is meant for trucks running 18-inch wheels rather than the 16-inch setup. Its low-profile metric format gives the buyer a more wheel-focused fitment to verify carefully. Choose this size only after confirming the truck’s actual wheel diameter and checking that the current wheel and suspension setup still matches the intended tire specification.
255/65R16 is a metric radial size with a 255 millimeter nominal section width, a 65-series profile, radial construction, and a 16-inch rim diameter. For the 2000 Land Rover Trucks Discovery, this size serves trucks equipped with 16-inch wheels and carries nearly the same overall diameter as the 18-inch alternative. That makes wheel diameter, not overall tire height, the key distinction between the two fitments. This size is the right one to evaluate if the truck retains its 16-inch wheels or if a replacement set has been matched to the original-style rim diameter.
Sub-model fitment is straightforward here because the Discovery Series II can use either of the two radial tire sizes associated with this vehicle. The key step is not trim identification so much as confirming whether the truck is on 16-inch or 18-inch wheels before selecting tires.

2000 Land Rover Trucks Discovery Series II
The 2000 Land Rover Trucks Discovery Series II uses radial tires and may be equipped with either the 255/65R16 or 255/55R18 size, depending on wheel diameter. Tire selection starts with verifying the wheel on the truck now, then choosing the proper replacement size to preserve fitment, clearance, and overall proportion.
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 2000 Land Rover Trucks Discovery usually come down to the correct tire size, the difference between the 16-inch and 18-inch wheel setups, and what to inspect before putting an older SUV back into regular road use.
Tire Size & Fitment
What tire size fits a 2000 Land Rover Trucks Discovery?
The 2000 Land Rover Trucks Discovery uses two primary tire sizes: 255/65R16 and 255/55R18. Both are radial sizes, and both are associated with the Discovery Series II. The difference between them is tied to wheel diameter rather than a change from one tire construction type to another.
Choosing the right one starts with checking the wheels currently on the truck. A 255/65R16 belongs on a 16-inch rim, while a 255/55R18 belongs on an 18-inch rim. Since the two sizes have very similar overall diameter, the main fitment question is confirming the actual wheel size and making sure any aftermarket wheel change has not altered the intended setup.
What size rim does a 2000 Land Rover Trucks Discovery use?
A 2000 Land Rover Trucks Discovery can use either a 16-inch rim or an 18-inch rim, depending on which tire size is on the vehicle. The 255/65R16 tire is matched to a 16-inch wheel, and the 255/55R18 tire is matched to an 18-inch wheel. Both are radial fitments for this model year.
That makes wheel confirmation especially important before ordering replacement tires. Looking only at the vehicle year and model is not enough when two rim diameters are possible. Check the size molded on the current tire sidewall and verify the wheel itself, particularly if the Discovery has had replacement wheels, trim changes, or suspension modifications during its service life.
Why does the 2000 Land Rover Trucks Discovery have more than one tire size?
The 2000 Land Rover Trucks Discovery has more than one tire size because it was fitted with two different wheel diameters. One setup uses 255/65R16 on a 16-inch rim, and the other uses 255/55R18 on an 18-inch rim. Both are radial sizes and both apply to the Discovery Series II.
That does not mean the sizes are interchangeable without checking the wheel first. The two tires are close in overall diameter, but each is built around a different rim diameter. A buyer should verify the current wheel setup, confirm that the wheels are the intended size, and inspect clearance if the truck has been altered from its original ride height or wheel configuration.
Choosing the Right Tire
What should I consider when choosing a tire for a 2000 Land Rover Trucks Discovery?
Start by confirming whether the truck uses the 255/65R16 size or the 255/55R18 size. Both are correct radial fitments for the 2000 Land Rover Trucks Discovery, but they are tied to different wheel diameters. That makes wheel size the first and most important part of selecting the right replacement tire.
After that, think about how the Discovery is actually used. A mostly stock road-driven truck should stay close to its present fitment, while a modified example needs closer attention to wheel width, suspension height, and clearance around steering and fenders. Matching the existing size is usually the cleanest starting point unless the wheel and suspension package has already been changed.
How do I choose between the available 255/65R16 and 255/55R18 tires for a 2000 Land Rover Trucks Discovery?
The choice between 255/65R16 and 255/55R18 is not really about preference if the truck still has one of its standard wheel diameters. Each tire size belongs to a specific rim: 16 inches for the 255/65R16 and 18 inches for the 255/55R18. The correct selection follows the wheel that is on the Discovery.
A useful next step is to confirm that the wheels currently installed are the ones you intend to keep. If the truck has been changed from 16-inch to 18-inch wheels, or vice versa, stay with the tire size that matches that wheel diameter. Also inspect turning clearance and suspension condition, since older SUVs can hide wear or prior modifications that affect fitment.
What rim-fitment details matter when choosing 2000 Land Rover Trucks Discovery tires?
The main rim-fitment detail is diameter. A 2000 Land Rover Trucks Discovery can use either a 16-inch wheel with 255/65R16 tires or an 18-inch wheel with 255/55R18 tires. Picking the right tire starts with matching the sidewall size to the actual wheel diameter already on the vehicle.
Beyond diameter, it is smart to inspect the wheel for width, condition, and any sign that it is not the original style of fitment. That matters even more if the truck has aftermarket wheels or a changed ride height. A tire that matches the rim diameter still needs sensible wheel compatibility and enough room through steering travel and suspension movement.
Restoration & Appearance
Which tire should I choose for a period-style 2000 Land Rover Trucks Discovery?
A period-style choice for a 2000 Land Rover Trucks Discovery starts with keeping the correct primary size for the wheel diameter on the truck. That means 255/65R16 for a 16-inch wheel or 255/55R18 for an 18-inch wheel. Since both are radial fitments, the appearance decision is really about preserving the Discovery’s intended stance and wheel-to-tire proportion.
Owners aiming for a restoration-oriented look should avoid treating tire selection as a generic SUV replacement purchase. Staying with the proper size helps maintain the truck’s visual balance and keeps the wheel opening from looking over- or under-filled. When exact originality matters, compare the current wheel package against marque references or period vehicle documentation before changing sizes.
Does correct tire fitment matter for a 2000 Land Rover Trucks Discovery restoration?
Yes, correct tire fitment matters because the 2000 Land Rover Trucks Discovery was built around specific radial sizes tied to either a 16-inch or 18-inch wheel. Using the proper size helps preserve the vehicle’s intended proportions and avoids a look that seems visually off, even if the tire can be mounted on a different wheel package.
Fitment also affects the restoration process beyond appearance alone. A mismatched tire and wheel combination can complicate clearance, steering feel, and the overall presentation of the truck. Keeping the tire size aligned with the correct wheel diameter is a sound starting point, especially on a Discovery being returned to a more stock, era-appropriate configuration.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2000 Land Rover Trucks Discovery?
Yes, modifications can affect tire fitment on a 2000 Land Rover Trucks Discovery even when the tire size itself is correct for the vehicle. Wheel changes, suspension lifts, lowering, altered offset, or body modifications can all influence how a 255/65R16 or 255/55R18 tire sits and clears during turning and suspension movement.
That is why a modified Discovery should be checked as an individual truck rather than judged by model year alone. Confirm wheel diameter first, then inspect wheel width, inner and outer clearance, and steering travel. A tire size that suits a stock vehicle may still need closer scrutiny if the chassis, wheels, or ride height no longer match standard configuration.
What should I inspect before driving a 2000 Land Rover Trucks Discovery on new tires?
Before driving a 2000 Land Rover Trucks Discovery on new tires, inspect the wheels, valve stems, and basic suspension condition, then confirm that the tire size matches the wheel diameter on the truck. It is also smart to check for rubbing points, uneven old-tire wear, and any signs of alignment or steering issues that could affect the new set.
A road-ready check should also include proper inflation, lug hardware condition, and a close look at brakes, bushings, and shocks on a higher-mileage SUV. Older utility vehicles can feel transformed by new tires, but they also reveal worn components quickly. A short initial drive with attention to pull, vibration, and clearance noise helps catch problems early.
How often should tires on a 2000 Land Rover Trucks Discovery be inspected?
Tires on a 2000 Land Rover Trucks Discovery should be inspected regularly, especially if the truck sees mixed use, sits for long periods, or spends time on rough surfaces. Routine checks should include air pressure, tread wear, cuts, bulges, and sidewall cracking. Collector-owned or lightly used SUVs deserve the same attention as daily-driven vehicles.
A good habit is to inspect the tires before longer drives and any time the Discovery has been parked for an extended period. It also helps to look for uneven wear that could point to alignment or suspension issues. Since this model can use either 16-inch or 18-inch wheel packages, verify that all four tires remain the correct size for the wheels installed.
