The 2002 Land Rover Trucks Discovery sits in the era when Discovery models had fully established themselves as upscale, highly capable SUVs with a strong following among owners who actually use them on the road and beyond the pavement. For many buyers today, the appeal is the blend of traditional Land Rover character with modern enough wheel and tire sizing to create real choice. This exact model uses radial tire fitments in either 255/55R18 or 255/65R16, so the first step is confirming which wheel diameter is on the vehicle. From there, the decision shifts to maintaining the intended stance and clearance while selecting the right size for the Discovery's actual wheel setup.
Which Tire Size Is Right for The 2002 Land Rover Trucks Discovery
The 2002 Land Rover Trucks Discovery uses two primary tire sizes, and both are radial fitments. The key difference is wheel diameter: one size is built for a 16-inch rim and the other for an 18-inch rim. Since both Series II SD and Series II SE models can use either size, the most important first step is verifying which wheels are actually on the vehicle before choosing tires.
A 255/55R18 tire uses a 255-millimeter section width, a 55-series aspect ratio, radial construction, and an 18-inch rim diameter. On a 2002 Land Rover Trucks Discovery, this size belongs to vehicles equipped with 18-inch wheels, so it is tied directly to the wheel package rather than to one exclusive sub-model. Its dimensions place it very close in overall height to the 255/65R16 alternative, but the wheel diameter requirement is different. This size is the right path only after confirming the vehicle is running 18-inch rims.
A 255/65R16 tire also uses a 255-millimeter section width and radial construction, but the 65-series profile is designed around a 16-inch rim. For the 2002 Land Rover Trucks Discovery, this size serves vehicles fitted with 16-inch wheels and keeps a very similar overall tire height to the 18-inch fitment. That makes wheel diameter, not overall size alone, the practical dividing line between the two options. This is the size to evaluate when the Discovery retains or has been converted to a 16-inch wheel setup.
Fitment is straightforward across the covered Discovery sub-models because both the Series II SD and Series II SE use the same two tire sizes. What matters most is not the trim name alone, but whether the vehicle is riding on 16-inch or 18-inch wheels.

2002 Land Rover Trucks Discovery Series II SD
The 2002 Land Rover Trucks Discovery Series II SD can use either 255/55R18 or 255/65R16, both in radial construction. Tire selection comes down to confirming the installed wheel diameter and then choosing the size that preserves proper wheel compatibility and vehicle clearance.
The 2002 Land Rover Trucks Discovery Series II SE also uses either 255/55R18 or 255/65R16 radial tires. That means the practical decision is verifying the wheel setup on the vehicle first, then selecting the matching tire size for the intended road use and overall fitment.
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 2002 Land Rover Trucks Discovery usually center on the two tire sizes, the difference between the 16-inch and 18-inch wheel setups, and what to inspect before putting a Discovery back into regular road use.
Tire Size & Fitment
What tire size fits a 2002 Land Rover Trucks Discovery?
The 2002 Land Rover Trucks Discovery uses two tire sizes: 255/55R18 and 255/65R16. Both are radial sizes, and both apply to this model depending on the wheel package installed on the vehicle. The overall tire dimensions are very close, but each size is built for a different rim diameter.
Choosing between them starts with the wheels, not the trim badge alone. A Discovery with 18-inch rims needs 255/55R18 tires, while one with 16-inch rims needs 255/65R16 tires. Before ordering, check the wheel diameter stamped on the wheel or confirm the size currently mounted, especially if the vehicle has had wheel changes over the years.
What size rim does a 2002 Land Rover Trucks Discovery use?
A 2002 Land Rover Trucks Discovery uses either a 16-inch or 18-inch rim, depending on which tire size is on the vehicle. The 255/65R16 fitment is for a 16-inch wheel, and the 255/55R18 fitment is for an 18-inch wheel. Both sizes are correct for this model in radial construction.
That two-wheel-diameter setup is why rim verification matters so much on this Discovery. A tire built for a 16-inch wheel cannot be mounted on an 18-inch wheel, and the reverse is equally true. Measuring or visually estimating is not enough when the vehicle has changed hands or been modified, so confirm the actual wheel size before selecting tires.
Do all 2002 Land Rover Trucks Discovery sub-models use the same tire size?
The Series II SD and Series II SE share the same fitment pattern, but that pattern includes two possible tire sizes rather than one. Both sub-models can use 255/55R18 or 255/65R16 radial tires. The difference comes from the wheel diameter fitted to the individual vehicle.
That means the sub-model name helps less than the wheel itself when choosing tires. An SD and an SE can both be correct with either size, so the practical check is whether the Discovery is wearing 16-inch or 18-inch rims today. This is especially important on used SUVs, where wheel swaps are common and can change the required tire size.
Choosing the Right Tire
What should I consider when choosing a tire for a 2002 Land Rover Trucks Discovery?
Start by matching the tire to the Discovery's actual wheel diameter. This model uses either 255/55R18 or 255/65R16, and both are radial sizes with very similar overall dimensions. The main selection point is not simply width or height, but choosing the size that belongs on the wheel currently installed.
After size confirmation, think about how the SUV is used and how original or modified the setup is. A Discovery that still runs its intended wheel package is easier to match correctly than one with aftermarket wheels or suspension changes. Clearance at full steering lock, wheel width compatibility, and the condition of suspension components should all be reviewed before final tire selection.
How do I choose between the available 255/55R18 and 255/65R16 tires for a 2002 Land Rover Trucks Discovery?
There is no preference between these two sizes unless the wheel diameter dictates it. The 255/55R18 size belongs on an 18-inch rim, while 255/65R16 belongs on a 16-inch rim. Their overall diameters are nearly the same, so the decision is primarily about wheel compatibility rather than trying to alter the vehicle's stance dramatically.
That close overall height can make the two sizes seem interchangeable, but the wheel fitment difference is decisive. Buyers should confirm not only the rim diameter, but also whether the vehicle still has its intended wheel setup or has been changed over time. Once the correct size is established, the next comparison points are construction consistency, clearance, and intended road use.
What rim-fitment details should I compare when choosing 2002 Land Rover Trucks Discovery tires?
The most important rim-fitment detail is diameter, because this Discovery uses both 16-inch and 18-inch wheel setups. A 255/65R16 is built only for a 16-inch rim, and a 255/55R18 is built only for an 18-inch rim. That is the first checkpoint before comparing any other tire characteristics.
After diameter, inspect the wheel for width suitability, signs of prior modification, and any mismatch between front and rear wheel setups. It also helps to check steering clearance and suspension condition, especially on an SUV that may have seen off-road use or aftermarket changes. Those details can matter just as much as the printed tire size when refining the final choice.
Restoration & Appearance
Which tire should I choose for a period-style 2002 Land Rover Trucks Discovery?
A period-style choice starts with retaining the correct size for the wheel package actually on the vehicle. For a 2002 Land Rover Trucks Discovery, that means 255/55R18 on 18-inch rims or 255/65R16 on 16-inch rims. Keeping the intended size relationship is the most important part of preserving the vehicle's original overall look.
Appearance on a Discovery from this era is shaped heavily by wheel-and-tire proportion, so an incorrect size can change the stance even if it mounts successfully. Owners pursuing a more faithful presentation should verify the wheel setup already on the SUV and compare it with marque-specific references or period vehicle documentation before making cosmetic changes through tire selection.
Does correct tire fitment matter for a 2002 Land Rover Trucks Discovery restoration?
Correct tire fitment matters because the 2002 Land Rover Trucks Discovery was built around two specific radial sizes tied to two specific wheel diameters. Using the right 255/55R18 or 255/65R16 size helps maintain the proper relationship between the body, wheel opening, and wheel package. That is an important part of keeping the vehicle visually coherent.
Restoration-minded buyers should look beyond the sidewall marking alone and confirm the actual wheels on the vehicle. A Discovery that has been changed over time may no longer match its earlier wheel setup, which can affect both appearance and fitment planning. Sorting that out before purchasing tires helps avoid a result that looks out of character or requires unnecessary rework.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2002 Land Rover Trucks Discovery?
Yes, modifications can affect tire fitment on a 2002 Land Rover Trucks Discovery even when the printed tire size looks close to stock. Wheel changes, suspension lifts, lowering, altered offsets, and body trimming can all change how a 255/55R18 or 255/65R16 tire sits in the wheel opening and how it behaves at full steering travel.
That matters because this Discovery already has two legitimate factory-style size paths based on wheel diameter, so a modified truck can be harder to assess at a glance. Checking wheel size, steering clearance, suspension travel, and any signs of rubbing is a smart step before installing tires. It is especially important when the vehicle's current configuration differs from how it left its earlier service life.
What should I inspect before driving a 2002 Land Rover Trucks Discovery on new tires?
Before road use, inspect the wheels, valve stems, and lug hardware, then confirm the tire size matches the rim diameter on the vehicle. It also helps to look at alignment wear patterns on the old tires, check for suspension looseness, and make sure nothing contacts the tire at full lock. Those basic checks support a cleaner installation and more predictable road manners.
A Discovery that has spent time parked deserves extra attention because age and storage can hide problems beyond the tires themselves. Sidewall clearance, brake component condition, and proper inflation should all be reviewed before regular driving resumes. A short test drive followed by another look for rubbing, air loss, or uneven seating can catch issues before a longer trip.
What should I check before a longer drive in a 2002 Land Rover Trucks Discovery?
Before a longer drive, make sure the Discovery is on the correct tire size for its wheel diameter and that all four tires are in sound condition. Check inflation, tread condition, visible cuts or bulges, and any signs of irregular wear. A vehicle using 255/55R18 tires should still be on 18-inch rims, while 255/65R16 belongs on 16-inch rims.
Longer trips put more heat and sustained load into the tire, so this is also a good time to inspect wheel balance behavior, steering response, and any vibration that may point to wheel or suspension issues. On a collector-era SUV that is not driven daily, rechecking tire condition after storage is just as important as checking mileage-related wear.
