The 2017 Land Rover Trucks Discovery marked a major shift for Discovery buyers, blending full-size family utility with the polished road manners and upscale presence expected from a modern Land Rover. It sits in that space between luxury SUV comfort and genuine all-terrain capability, which makes proper tire selection especially important. This Discovery uses radial tire fitments in four sizes, from 255/60R19 through 285/40R22, with size choice tied to the exact sub-model and wheel package. That creates real decisions around wheel diameter, sidewall profile, and intended use. For everyday driving, appearance, and clearance, the first step is confirming which wheel and trim combination the vehicle actually has.
Which Tire Size Is Right for The 2017 Land Rover Trucks Discovery
The 2017 Land Rover Trucks Discovery uses four primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. These are all radial fitments, but they span 19-inch, 20-inch, 21-inch, and 22-inch rims, so confirming the wheel diameter should come first. Once that is settled, the real decision becomes choosing the proper profile and fitment for the way the Discovery is equipped and driven.
The size 275/45R21 indicates a metric radial tire that is 275 millimeters wide, uses a 45-series aspect ratio, and mounts on a 21-inch wheel. On the 2017 Land Rover Trucks Discovery, this size represents one of the larger factory-style wheel fitments and keeps the vehicle in a modern radial construction. Its dimensions place it close to the other Discovery sizes in overall diameter, while changing the wheel-to-sidewall balance. This size should be chosen only when the vehicle is equipped for the 21-inch setup used on the applicable sub-model configuration.
The size 285/40R22 is a metric radial with a 285-millimeter section width, a 40-series profile, and a 22-inch rim diameter. For the 2017 Land Rover Trucks Discovery, it is the largest wheel fitment in the range and gives the vehicle a lower-profile tire presentation than the smaller-diameter options. It remains a modern radial design, but its shorter sidewall changes the visual character and the wheel requirement at the same time. This size belongs on Discovery configurations equipped with the 22-inch wheel package rather than as a general substitute across the lineup.
The 255/55R20 size uses a 255-millimeter section width, a 55-series aspect ratio, and a 20-inch rim in modern radial construction. On the 2017 Land Rover Trucks Discovery, it sits in the middle of the fitment range and balances a substantial sidewall with a large-diameter wheel. Its overall diameter is very close to the other primary Discovery sizes, but the wheel and sidewall proportions are different enough that correct wheel confirmation still matters. This is the size to evaluate when the vehicle carries one of the 20-inch fitments used on the applicable HSE, HSE Luxury, or SE configurations.
The size 255/60R19 is a metric radial tire with a 255-millimeter width, a 60-series profile, and a 19-inch wheel diameter. Within the 2017 Land Rover Trucks Discovery range, it provides the tallest sidewall of the primary fitments while staying close to the other sizes in overall diameter. That makes it distinct mainly in wheel size and sidewall profile rather than in total tire height. This size should be considered for Discovery setups equipped with the 19-inch wheel package, especially on SE models where wheel choice can determine the correct fitment.
Tire fitment on the 2017 Land Rover Trucks Discovery varies by sub-model, and several trims can use more than one wheel and tire package. Checking the exact trim and actual wheel diameter matters before choosing a replacement tire, especially because the Discovery spans four different rim sizes.

2017 Land Rover Trucks Discovery First Edition
The 2017 Land Rover Trucks Discovery First Edition uses larger-diameter radial fitments, with 21-inch and 22-inch wheel packages rather than the smaller Discovery sizes. That means tire selection starts with confirming which wheel is on the vehicle, then matching the correct profile for appearance, clearance, and intended road use.
The 2017 Land Rover Trucks Discovery HSE spans three radial tire sizes across 20-inch, 21-inch, and 22-inch wheel setups. Tire choice depends on the actual wheel package fitted to the vehicle, so matching the installed rim diameter is more important than choosing by trim name alone.
The 2017 Land Rover Trucks Discovery HSE Luxury also uses multiple radial fitments, covering 20-inch, 21-inch, and 22-inch wheel combinations. That gives the owner several possible replacement paths, but the correct starting point is always the wheel diameter currently on the vehicle and the tire size already matched to it.
The 2017 Land Rover Trucks Discovery SE has the widest fitment spread, covering 19-inch, 20-inch, 21-inch, and 22-inch radial tire setups. For this trim in particular, replacement selection depends on verifying the exact wheel package on the SUV rather than assuming all SE models share the same 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.
Frequently Asked Questions
These FAQs focus on the 2017 Land Rover Trucks Discovery tire sizes, trim-specific wheel fitment, and the practical checks that matter before replacing tires on a modern Discovery with 19-inch through 22-inch wheel packages.
Tire Size & Fitment
What tire size fits a 2017 Land Rover Trucks Discovery?
A 2017 Land Rover Trucks Discovery can use 255/60R19, 255/55R20, 275/45R21, or 285/40R22, depending on the exact sub-model and wheel package. All four are radial tire sizes, and each one is tied to a specific rim diameter rather than being a universal fit across the entire Discovery lineup.
The practical first step is to confirm the wheel diameter actually on the vehicle. Several Discovery trims were offered with more than one wheel and tire combination, so using the existing sidewall size and checking the installed wheel helps avoid choosing a tire that matches the trim name but not the actual setup.
What size rim does a 2017 Land Rover Trucks Discovery use?
The 2017 Land Rover Trucks Discovery uses 19-inch, 20-inch, 21-inch, or 22-inch rims, depending on trim and wheel package. Those rim diameters correspond to the primary tire sizes 255/60R19, 255/55R20, 275/45R21, and 285/40R22, all in radial construction.
Rim diameter is the key fitment checkpoint on this Discovery because the tire lineup spans four distinct wheel sizes. Before selecting a replacement, verify the actual wheel on the vehicle rather than relying only on model name, since several sub-models were available with multiple factory-style wheel and tire combinations.
Do all 2017 Land Rover Trucks Discovery sub-models use the same tire size?
No, the 2017 Land Rover Trucks Discovery sub-models do not all use the same tire size. The SE can use four sizes, the HSE and HSE Luxury can use three, and the First Edition uses two larger-diameter fitments. Tire choice varies with the wheel package fitted to the specific vehicle.
That means trim level alone is not always enough to choose a replacement tire. A Discovery SE, HSE, or HSE Luxury may be riding on different wheel diameters from another vehicle with the same trim badge, so checking the current sidewall marking and wheel size is the safest way to confirm fitment.
Choosing the Right Tire
What should I consider when choosing a tire for a 2017 Land Rover Trucks Discovery?
Start with the exact size already matched to the vehicle: 255/60R19, 255/55R20, 275/45R21, or 285/40R22. On a 2017 Land Rover Trucks Discovery, the correct choice depends on the installed wheel diameter first, because each tire size is designed around a different rim and sidewall profile.
After confirming size, think about how the Discovery is used. A 19-inch or 20-inch setup presents a different sidewall profile than a 21-inch or 22-inch setup, so replacement decisions should account for ride expectations, appearance, and any wheel or suspension changes that may affect clearance.
How do I choose between the available tires for a 2017 Land Rover Trucks Discovery?
The main choice is not between unrelated sizes, but between the tire that matches the wheel package already on the Discovery. A 2017 Land Rover Trucks Discovery with 19-inch wheels needs a different tire than one equipped with 22-inch wheels, even though the overall diameters remain fairly close.
Once the correct size is confirmed, compare the tire's profile in relation to the vehicle's intended use and setup. Owners should also look at how the SUV is currently configured, especially if wheels have been changed, because a tire that is correct for one Discovery package may not suit another wheel diameter or modified arrangement.
What tire series are available for the 2017 Land Rover Trucks Discovery?
The 2017 Land Rover Trucks Discovery uses four primary metric radial sizes, but no tire-series assortment is presented here for those fitments. The key decision remains selecting the correct size and rim diameter combination before moving on to any product-specific comparison.
That makes fitment accuracy more important than series naming on this page. Once the wheel diameter and size are verified on the vehicle, the next step is comparing actual tire options that match that setup, rather than assuming one Discovery trim always uses the same product line across every wheel package.
Restoration & Appearance
Does correct tire fitment matter for a 2017 Land Rover Trucks Discovery restoration or refurbishment?
Yes, correct tire fitment still matters on a 2017 Land Rover Trucks Discovery, even though it is a modern SUV rather than a vintage restoration project. The Discovery was offered with multiple wheel and tire combinations, so keeping the proper size on the proper rim helps preserve the vehicle's intended stance and overall presentation.
Appearance changes noticeably as the Discovery moves from 19-inch to 22-inch fitments because sidewall profile and wheel presence change together. Anyone refreshing one of these vehicles should confirm the exact wheel package already fitted, especially if the goal is to maintain a clean, model-appropriate look rather than create a custom setup.
How does tire size affect the appearance of a 2017 Land Rover Trucks Discovery?
Tire size affects the 2017 Land Rover Trucks Discovery mainly through wheel diameter and sidewall profile. A 255/60R19 presents more visible sidewall, while a 285/40R22 puts more visual emphasis on the wheel. The intermediate 20-inch and 21-inch fitments sit between those two appearance extremes.
That visual difference is important when replacing tires on a Discovery that you want to keep close to its original character. Matching the size already paired with the vehicle's wheel package helps maintain the intended proportion, while switching to a different rim diameter changes the look even when overall tire height stays relatively similar.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Land Rover Trucks Discovery?
Yes, modifications can affect tire fitment on a 2017 Land Rover Trucks Discovery. Wheel changes, altered offsets, suspension modifications, and ride-height changes can all influence how a 255/60R19, 255/55R20, 275/45R21, or 285/40R22 tire sits in the wheel opening and clears surrounding components.
A Discovery that no longer has its original wheel setup should be checked carefully before replacement tires are chosen. Confirm wheel diameter first, then look at width, steering clearance, and fender space so the selected tire matches the vehicle as it sits now, not just the way that trim may have left the factory.
What should I inspect before driving a 2017 Land Rover Trucks Discovery on new tires?
Before driving a 2017 Land Rover Trucks Discovery on new tires, inspect the wheels for correct diameter and condition, confirm the installed tire size matches the vehicle's setup, and check that the tires have proper inflation. It is also worth looking over suspension and steering components for anything that could affect tracking or tire wear.
A short clearance check is especially useful on a Discovery because the model spans four wheel diameters and some vehicles may have been altered over time. Make sure there is no rubbing at full steering lock, watch for unusual air loss after installation, and recheck the tires after the first few drives.
What should I check before a longer drive in a 2017 Land Rover Trucks Discovery?
Before a longer drive, check tire pressure, tread condition, sidewall condition, and any signs of cuts, bulges, or cracking on the 2017 Land Rover Trucks Discovery. It is also smart to confirm that all four tires match the intended size for the wheel package on the vehicle, especially on a used Discovery.
Longer trips put more emphasis on stability and heat buildup, so a careful pre-drive inspection is worthwhile even when the tires look good at a glance. Take an extra moment to verify there is no rubbing, no uneven wear pattern, and no slow air loss that could become more noticeable once the SUV is driven at highway speed.
