The 2017 Lincoln Trucks MKX sits in the modern luxury crossover category, blending Lincoln comfort and styling with the road manners buyers expect from a premium daily-driven utility vehicle. For this model year, tire selection centers on trim-specific radial fitment rather than a single universal size. The MKX uses 245/60R18, 245/50R20, or 265/40R21 depending on the sub-model and wheel package. That makes wheel diameter the first detail to confirm, followed by whether the goal is a standard replacement feel or a more appearance-driven upgrade within the correct size. For the best result, match the tire to the exact trim and actual wheel setup on the vehicle.
Which Tire Size Is Right for The 2017 Lincoln Trucks MKX
Three tire sizes apply to the 2017 Lincoln Trucks MKX, and they are tied to specific sub-models and wheel diameters. All are radial metric sizes, but the vehicle uses 18-inch, 20-inch, or 21-inch rims depending on configuration. The first step is confirming the exact sub-model and the wheel diameter currently on the vehicle, especially if it has been changed from stock. Once that is settled, the decision becomes choosing the right tire within the correct size and profile.
245/50R20 is a metric radial size in which 245 identifies the section width in millimeters, 50 is the aspect ratio, R indicates radial construction, and 20 is the rim diameter in inches. On the 2017 Lincoln Trucks MKX, this size suits trims equipped with 20-inch wheels and maintains the modern low-profile look associated with larger-diameter luxury crossover fitments. Its profile sits between the 18-inch and 21-inch options in sidewall height. This size is the right one to evaluate when the vehicle already wears 20-inch wheels and the goal is to keep the same overall fitment style.
265/40R21 is a metric radial size that uses a 265-millimeter nominal section width, a 40-series aspect ratio, and a 21-inch rim diameter. For the 2017 Lincoln Trucks MKX, this is the most aggressive-looking of the three primary sizes, combining the widest section width here with the shortest sidewall profile. It is associated with trims using 21-inch wheels rather than serving as a universal MKX fitment. This size deserves a close wheel and clearance check whenever the vehicle has seen wheel changes, because 21-inch fitment leaves less room for casual size substitution.
245/60R18 is a metric radial size with a 245-millimeter nominal section width, a 60-series aspect ratio, and an 18-inch rim diameter. On the 2017 Lincoln Trucks MKX, it represents the taller-sidewall fitment used on trims equipped with 18-inch wheels. That gives it a different visual and ride-profile character from the 20-inch and 21-inch options without changing the fact that it remains a modern radial crossover size. This is the correct size to focus on when the vehicle has 18-inch wheels and the buyer wants to preserve the intended wheel-to-tire relationship.
Sub-model fitment matters on the 2017 Lincoln Trucks MKX because tire size changes with trim and wheel package. Some versions use one size only, while Black Label and Reserve can use either 20-inch or 21-inch fitments, so the exact wheel setup should be confirmed before selecting tires.

2017 Lincoln Trucks MKX Black Label
The 2017 Lincoln Trucks MKX Black Label uses radial tires in either 245/50R20 or 265/40R21 depending on the wheel package installed. That means tire selection starts with confirming whether the vehicle has 20-inch or 21-inch wheels, then choosing a replacement that keeps the correct profile for that setup.
The 2017 Lincoln Trucks MKX Premiere uses the 245/60R18 radial size. Tire choice is more straightforward here, with the main priority being an 18-inch replacement that preserves the intended fitment rather than mixing in one of the larger-wheel MKX sizes.
The 2017 Lincoln Trucks MKX Reserve uses radial tires in either 245/50R20 or 265/40R21, so there is more than one correct fitment depending on the wheel package. Selecting tires for a Reserve starts with the actual rim diameter on the vehicle, especially if wheels have been swapped since new.
The 2017 Lincoln Trucks MKX Select uses the 245/60R18 radial size. For this trim, the tire decision is less about multiple primary sizes and more about choosing an 18-inch radial that matches the vehicle's intended dimensions and wheel setup.
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
Tire questions for the 2017 Lincoln Trucks MKX usually come down to trim-specific size, wheel diameter, and how to select the right radial replacement. The FAQs below focus on fitment, wheel confirmation, product-selection priorities, and road-use checks for this exact MKX.
Tire Size & Fitment
What tire size fits a 2017 Lincoln Trucks MKX?
The 2017 Lincoln Trucks MKX uses three possible tire sizes: 245/60R18, 245/50R20, and 265/40R21. All three are radial sizes, but they do not apply across every trim in the same way. Premiere and Select use 245/60R18, while Black Label and Reserve can use either 245/50R20 or 265/40R21 depending on wheel package.
The practical takeaway is that fitment starts with the exact trim and the wheel diameter currently on the vehicle. A quick look at the tire sidewall and wheel size is the safest way to confirm what belongs there now, especially if the MKX has had replacement wheels installed at some point.
What size rim does a 2017 Lincoln Trucks MKX use?
A 2017 Lincoln Trucks MKX uses 18-inch, 20-inch, or 21-inch rims depending on the sub-model and wheel package. The 245/60R18 tire mounts on an 18-inch rim, 245/50R20 mounts on a 20-inch rim, and 265/40R21 mounts on a 21-inch rim. Rim diameter is built directly into each tire size.
That makes wheel confirmation the first step before buying tires. Even within the same model year, a Black Label or Reserve may not use the same wheel diameter as a Premiere or Select, and an MKX with aftermarket wheels should be measured by its actual setup rather than assumed from trim name alone.
Do all 2017 Lincoln Trucks MKX sub-models use the same tire size?
No, the 2017 Lincoln Trucks MKX does not use one tire size across every sub-model. Premiere and Select use 245/60R18, while Black Label and Reserve use either 245/50R20 or 265/40R21. The vehicle stays within radial construction throughout, but the wheel diameter and tire profile vary by configuration.
That difference matters because a tire matched to one MKX trim may be completely wrong for another if the wheel diameter is different. Buyers should confirm both the sub-model and the actual wheel currently on the vehicle so the replacement tire preserves proper mounting and clearance.
Choosing the Right Tire
What should I consider when choosing a tire for a 2017 Lincoln Trucks MKX?
Start with the exact tire size already tied to the vehicle's trim and wheel diameter: 245/60R18, 245/50R20, or 265/40R21. Because all three are radial fitments, the main decision is not construction type but staying with the correct size, profile, and rim diameter for the vehicle's current setup.
From there, compare the tire's intended use, ride priorities, and the actual wheel package on the MKX. A vehicle on 18-inch wheels should not be treated like one on 20-inch or 21-inch wheels, and any prior wheel changes make it worth double-checking sidewall markings before final selection.
How do I choose between the available 2017 Lincoln Trucks MKX tire sizes?
The choice is made by fitment, not preference alone. A 2017 Lincoln Trucks MKX on 18-inch wheels uses 245/60R18, a 20-inch setup uses 245/50R20, and a 21-inch setup uses 265/40R21. Those sizes reflect different wheel diameters and sidewall profiles, so they are not interchangeable simply because they belong to the same model line.
Once the correct size is confirmed, then it makes sense to compare replacement tires within that size. Looking at the wheel diameter first prevents common mistakes, especially on Black Label and Reserve trims where more than one primary fitment is possible depending on the wheels installed.
How do I choose between the available 245/50R20 tires for a 2017 Lincoln Trucks MKX?
For a 2017 Lincoln Trucks MKX that uses 245/50R20, begin by confirming that the vehicle actually has the 20-inch wheel package. After that, compare replacement tires within the same size based on the kind of driving the MKX sees most, while keeping the same metric radial fitment and overall wheel relationship intact.
It also helps to review the tire's profile in relation to the vehicle's appearance and ride expectations. A 20-inch MKX fitment sits between the taller-sidewall 18-inch setup and the lower-profile 21-inch setup, so staying within 245/50R20 keeps the vehicle aligned with that original wheel-and-tire balance.
Restoration & Appearance
Does correct tire fitment matter for a 2017 Lincoln Trucks MKX restoration?
Yes, correct tire fitment still matters on a 2017 Lincoln Trucks MKX even though it is a newer luxury crossover rather than a vintage restoration project. Using the right size for the trim and wheel package preserves the intended visual proportion between wheel, sidewall, and body, whether the vehicle uses 245/60R18, 245/50R20, or 265/40R21.
Appearance can change noticeably when the sidewall profile or rim diameter shifts away from the proper setup. Anyone aiming to return an MKX to a stock-style presentation should confirm the original wheel package on that specific vehicle first, then match the tire size to that configuration rather than choosing by appearance alone.
How does tire size affect the appearance of a 2017 Lincoln Trucks MKX?
Tire size changes the visual character of the 2017 Lincoln Trucks MKX because each fitment pairs a different sidewall height with a different wheel diameter. The 245/60R18 setup presents more sidewall, 245/50R20 sits in the middle, and 265/40R21 gives the vehicle the lowest-profile look of the three primary sizes.
That means appearance-driven changes should be approached carefully. A larger wheel and shorter sidewall can alter the vehicle's stance and visual balance, but the safer path is to stay with the size intended for the MKX's actual wheel package unless the entire wheel-and-tire setup is being evaluated together.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Lincoln Trucks MKX?
Yes, modifications can affect tire fitment on a 2017 Lincoln Trucks MKX. Aftermarket wheels, suspension changes, lowering, or body alterations can change the clearance available for 245/60R18, 245/50R20, or 265/40R21 tires. Even when the tire size itself is familiar for the model, the actual vehicle may no longer match the original wheel position or profile.
That is why modified vehicles should be checked at the wheel, not judged by trim name alone. Measuring current rim diameter and verifying steering, fender, and suspension clearance helps prevent rubbing or mismatch issues, especially on the 20-inch and 21-inch MKX configurations where profile is already tighter.
What should I inspect before driving a 2017 Lincoln Trucks MKX on new tires?
Before driving a 2017 Lincoln Trucks MKX on new tires, confirm that the installed size matches the wheel diameter on the vehicle and that all four tires are appropriate for that setup. It is also wise to inspect inflation pressure, wheel condition, lug hardware, and any visible contact points around the fenders, suspension, and steering components.
A short initial drive followed by a recheck can catch issues early. Look for any signs of rubbing, vibration, unusual air loss, or uneven seating, and keep an eye on alignment-related wear afterward. Those basic checks matter on any MKX, but they are especially important when wheel packages differ by trim.
How often should tires on a 2017 Lincoln Trucks MKX be inspected?
Tires on a 2017 Lincoln Trucks MKX should be inspected regularly rather than only when a problem appears. A visual check for cuts, bulges, irregular wear, and air loss is a smart routine on any size the MKX uses, whether 245/60R18, 245/50R20, or 265/40R21. Pressure should also be checked often enough to catch gradual changes.
Regular inspection becomes even more important if the vehicle is driven infrequently or sits for long periods. Low-use vehicles can still develop age-related issues, and catching sidewall cracking, flat spotting, or slow leaks early helps protect ride quality and preserves proper fitment before longer road use.
