The 2018 Land Rover Trucks Discovery Sport blends compact luxury SUV packaging with the brand’s modern all-weather, all-purpose character, making tire choice especially important for owners who want the right balance of appearance, road manners, and wheel fitment. This model uses three primary radial tire sizes: 235/60R18, 235/55R19, and 245/45R20. That means the first decision is confirming which wheel package is actually on the vehicle, since trim level and equipment affect fitment. Once size is confirmed, the choices center on tire series, brand, and sidewall style, particularly in 245/45R20. For daily driving, replacement planning, or a carefully kept example, matching the tire to the wheel setup matters more than making assumptions by trim name alone.
Which Tire Size Is Right for The 2018 Land Rover Trucks Discovery Sport
The 2018 Land Rover Trucks Discovery Sport uses three primary tire sizes, and they vary by sub-model and wheel diameter. The key step is identifying the exact trim and confirming whether the vehicle has 18-inch, 19-inch, or 20-inch wheels, because each size is tied to a specific rim diameter. Once that is settled, the decision becomes choosing the right radial tire within the correct size and wheel package.
Fit(s): HSE, HSE (3rd Row Seat), HSE Luxury, HSE Luxury (3rd Row Seat), SE, and SE (3rd Row Seat)
Construction: Radial|Rim: 19 in
The 235/55R19 size uses a metric format: 235 is the nominal section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 19 is the rim diameter in inches. On the 2018 Land Rover Trucks Discovery Sport, this is one of the primary modern radial fitments and is used across several sub-models. Its dimensions place it very close to the other Discovery Sport fitments in overall height, but it remains a distinct 19-inch wheel application. This size should be chosen only after confirming that the vehicle is equipped with the corresponding 19-inch wheel package.
Fit(s): HSE, HSE (3rd Row Seat), SE, and SE (3rd Row Seat)
Construction: Radial|Rim: 18 in
The 235/60R18 code indicates a 235-millimeter-wide radial tire with a 60-series profile for an 18-inch rim. For the 2018 Land Rover Trucks Discovery Sport, this size serves specific sub-model configurations rather than every version of the vehicle. Its overall diameter is close to the 19-inch fitment, but the tire is built for a different wheel diameter, so wheel confirmation comes first. Buyers considering this size should focus on matching the vehicle’s actual 18-inch setup instead of selecting by appearance or trim name alone.
The 245/45R20 designation means a 245-millimeter section width, a 45-series profile, radial construction, and a 20-inch rim diameter. On the 2018 Land Rover Trucks Discovery Sport, this size is tied to 20-inch wheel applications and brings the broadest visible product variety, including BFGoodrich, Nitto, and Pro-Trac options in different tire series and sidewall treatments such as Blackwall, Redline, and RWL. That makes it as much a selection question as a fitment question. After confirming the 20-inch wheel package, buyers can compare appearance, rim-width compatibility, and product character within the correct size.
2018 Land Rover Trucks Discovery Sport Sub-Model Tires
Tire fitment on the 2018 Land Rover Trucks Discovery Sport depends on the exact sub-model and wheel package, because not every trim uses the same set of sizes. Checking the specific version matters before comparing products, especially when the vehicle could be on 18-inch, 19-inch, or 20-inch wheels.

2018 Land Rover Trucks Discovery Sport HSE
The 2018 Land Rover Trucks Discovery Sport HSE can use 18-inch, 19-inch, or 20-inch radial fitments depending on how the vehicle is equipped. Tire selection starts with confirming the installed wheel diameter, then choosing the right radial tire within that exact size.
2018 Land Rover Trucks Discovery Sport HSE (3rd Row Seat)
The HSE with 3rd Row Seat shares the same broad fitment pattern as the standard HSE, with radial tire options tied to 18-inch, 19-inch, or 20-inch wheels. The practical takeaway is simple: verify the wheel package on the vehicle before narrowing the product choices.
The 2018 Land Rover Trucks Discovery Sport HSE Luxury uses 19-inch or 20-inch radial fitments rather than the full three-size spread seen on some other trims. That makes wheel confirmation especially important, since the decision comes down to whether the vehicle is on the 19-inch or 20-inch setup.
2018 Land Rover Trucks Discovery Sport HSE Luxury (3rd Row Seat)
The HSE Luxury with 3rd Row Seat follows the same two-size radial fitment pattern as the other HSE Luxury configuration. Buyers should confirm whether the vehicle carries 19-inch or 20-inch wheels, then compare tire options that match that specific diameter and size.
The 2018 Land Rover Trucks Discovery Sport SE uses either 18-inch or 19-inch radial fitments, depending on the wheel setup. That means the tire choice is less about broad trim assumptions and more about checking the actual wheel diameter before selecting a replacement tire.
2018 Land Rover Trucks Discovery Sport SE (3rd Row Seat)
The SE with 3rd Row Seat also uses either the 18-inch or 19-inch radial fitment, matching the general pattern of the standard SE. Selection is straightforward once the wheel diameter is confirmed, since that immediately narrows the correct tire 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.

Tire Size & Fitment
What tire size fits a 2018 Land Rover Trucks Discovery Sport?
The 2018 Land Rover Trucks Discovery Sport uses three primary tire sizes: 235/60R18, 235/55R19, and 245/45R20. All three are radial sizes, and the correct one depends on the sub-model and, just as importantly, the wheel package installed on the vehicle.
The most useful next step is to confirm the actual wheel diameter on the Discovery Sport rather than relying only on trim name. An 18-inch wheel requires 235/60R18, a 19-inch wheel uses 235/55R19, and a 20-inch wheel uses 245/45R20, so replacement starts with the wheel that is physically on the vehicle.
What size rim does a 2018 Land Rover Trucks Discovery Sport use?
A 2018 Land Rover Trucks Discovery Sport can use 18-inch, 19-inch, or 20-inch rims, depending on the specific sub-model and equipment. Those rim diameters correspond to the three primary tire sizes used on this vehicle: 235/60R18, 235/55R19, and 245/45R20.
Wheel diameter should be verified before choosing tires, because tires for one rim size do not serve as replacements for another. It also helps to confirm wheel width and any prior wheel changes, especially on used vehicles, since aftermarket wheels can complicate fitment even when the sub-model name appears to point toward a factory wheel package.
Why does the 2018 Land Rover Trucks Discovery Sport have more than one tire size?
The 2018 Land Rover Trucks Discovery Sport has more than one tire size because different sub-models and wheel packages use different rim diameters. Some versions can be equipped with 18-inch and 19-inch tires, some use 19-inch and 20-inch tires, and HSE models span all three sizes.
That means tire replacement is a configuration question, not just a model-year question. The safest approach is to check the exact sub-model, then verify the wheel size currently on the vehicle and confirm the tire size already mounted, especially if the Discovery Sport has changed hands or may have had wheels replaced earlier in its life.
Choosing the Right Tire
What should I consider when choosing a tire for a 2018 Land Rover Trucks Discovery Sport?
Start with the correct size for the wheel package on the 2018 Land Rover Trucks Discovery Sport: 235/60R18, 235/55R19, or 245/45R20. From there, compare radial construction details that matter to the vehicle’s setup, including rim-diameter match, wheel-width suitability, and the type of driving the vehicle sees most often.
Appearance and product character may also shape the decision, especially in 245/45R20 where there is more visible variety. A buyer may prefer a straightforward Blackwall look, or choose a Redline or RWL treatment for a more customized presentation, but those style choices only make sense after the underlying size and wheel fitment are confirmed.
What sidewall styles are available for 2018 Land Rover Trucks Discovery Sport tires?
Sidewall style variety appears in the 245/45R20 fitment for the 2018 Land Rover Trucks Discovery Sport. Available choices include Blackwall, Redline, and RWL, giving owners a range from a more understated modern look to a more distinctive custom-oriented presentation.
Sidewall style should be treated as a finishing decision rather than the starting point. Once the Discovery Sport’s wheel diameter and correct tire size are confirmed, the sidewall treatment can help shape the vehicle’s visual character without changing the need to match the tire properly to the wheel and overall fitment requirements.
What brands offer tires for the 2018 Land Rover Trucks Discovery Sport?
In the 245/45R20 fitment, the 2018 Land Rover Trucks Discovery Sport has product options from BFGoodrich, Nitto, and Pro-Trac. Those brands cover several radial tire series, which gives buyers a meaningful range of choices within the correct 20-inch size.
Brand should be considered alongside size, wheel compatibility, sidewall style, and the intended look of the vehicle. Some owners may focus on a cleaner Blackwall presentation, while others may want Redline or RWL styling, so the smartest comparison is between products that already match the Discovery Sport’s exact wheel diameter and tire size.
Restoration & Appearance
How does tire construction affect the appearance of a restored 2018 Land Rover Trucks Discovery Sport?
On a 2018 Land Rover Trucks Discovery Sport, tire construction is straightforward because the primary fitments are radial. The visual difference comes less from construction type and more from the tire’s profile, series, and sidewall treatment, particularly on 20-inch applications where styling choices are more visible.
For an owner preserving a clean, well-kept example, the goal is usually to maintain the proper modern SUV stance rather than chase a vintage-style presentation. Matching the original wheel diameter and staying with the correct size keeps the vehicle’s proportions in line, while sidewall choices such as Blackwall, Redline, or RWL influence the finished look.
Does correct tire fitment matter for a 2018 Land Rover Trucks Discovery Sport restoration or preservation project?
Correct tire fitment matters on a 2018 Land Rover Trucks Discovery Sport because the vehicle uses multiple wheel diameters and tire sizes across its sub-model range. Preserving the proper relationship between tire size and wheel size helps maintain the vehicle’s intended stance and avoids a mismatched look.
That is especially important on a well-kept example where appearance and proportion both count. Even when the goal is more preservation than full restoration, checking the exact wheel package first prevents cosmetic decisions from overriding fitment basics, and it helps keep the Discovery Sport visually consistent with the way that configuration was equipped.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Land Rover Trucks Discovery Sport?
Yes. Modifications can affect tire fitment on a 2018 Land Rover Trucks Discovery Sport, especially if the vehicle has aftermarket wheels, suspension changes, or altered ride height. Since this model already uses multiple factory wheel diameters, any change to wheel width or offset can complicate the correct replacement choice.
A Discovery Sport with non-original wheels should be measured rather than assumed to follow factory trim patterns. Confirm the actual rim diameter, check wheel width, and inspect clearance at the fenders and suspension before selecting a replacement tire, particularly when moving between 18-inch, 19-inch, and 20-inch wheel setups.
What should I inspect before driving a 2018 Land Rover Trucks Discovery Sport on new tires?
Before driving a 2018 Land Rover Trucks Discovery Sport on new tires, inspect the wheels for damage, confirm the tires match the correct size for the rim diameter, and make sure inflation is set properly. It also helps to look over alignment-related wear patterns on the old tires before they come off.
A short post-installation check is worthwhile as well. Watch for rubbing during low-speed turns, verify there is no unusual vibration, and recheck air pressure after the first few drives. Those simple steps help confirm that the new tires suit the Discovery Sport’s actual wheel setup and are settling in as expected.
How often should tires on a 2018 Land Rover Trucks Discovery Sport be inspected?
Tires on a 2018 Land Rover Trucks Discovery Sport should be inspected regularly, even when tread depth still looks acceptable. Routine checks should cover air pressure, tread wear, sidewall condition, punctures, and any signs of irregular wear that could point to alignment or suspension issues.
A monthly visual inspection is a good baseline, with an extra check before longer highway trips or seasonal weather changes. Because this model may be equipped with several different wheel and tire combinations, staying attentive to wear and condition helps catch fitment or maintenance problems early, before they become more expensive or inconvenient.
