The 2015 Lincoln Trucks MKX sits in the modern luxury crossover segment, blending Lincoln comfort and road manners with the stance and wheel presence buyers often expect from this generation. Tire choice on this exact MKX centers on three radial fitments: 245/60R18, 245/50R20, and 265/40R22. That means the first step is confirming which wheel diameter is on the vehicle before choosing a replacement tire. With no bias-ply fitment to weigh against modern construction, the real decision comes down to staying with the proper size, matching the vehicle’s wheel setup, and selecting a tire that suits everyday road use and the MKX’s intended look.
Which Tire Size Is Right for The 2015 Lincoln Trucks MKX
The 2015 Lincoln Trucks MKX uses three primary tire sizes, and the difference comes down to wheel diameter rather than tire construction, since all three fitments are radial. Before selecting a tire, confirm whether the vehicle is on 18-inch, 20-inch, or 22-inch wheels. Once that is settled, the choice becomes finding the correct size for the actual wheel package on the vehicle and checking that any replacement matches the existing setup.
245/50R20 is a metric radial size in which 245 is the nominal section width in millimeters, 50 is the aspect ratio, R identifies radial construction, and 20 is the wheel diameter in inches. On the 2015 Lincoln Trucks MKX, this size supports a lower-profile look than the 18-inch fitment while remaining within the vehicle’s primary radial sizing range. Its published dimensions place it close in overall diameter to the 18-inch option. This size makes sense when the MKX already carries 20-inch wheels and the goal is to maintain the existing wheel-and-tire package.
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. For the 2015 Lincoln Trucks MKX, it represents the 18-inch wheel fitment and keeps the same basic modern radial construction used across the model’s tire lineup. Its dimensions are very close in overall diameter to the 245/50R20 alternative, but it is still a separate primary fitment tied to a different wheel size. This is the size to use when the vehicle is equipped with 18-inch wheels and the existing setup is being retained.
265/40R22 is a metric radial size where 265 denotes nominal section width in millimeters, 40 is the aspect ratio, R marks radial construction, and 22 identifies the wheel diameter in inches. On the 2015 Lincoln Trucks MKX, this is the largest wheel fitment of the three primary sizes and carries a wider, lower-profile presentation than the 18-inch and 20-inch options. Its overall diameter remains in the same general range, but the wheel and tire package is distinct. This size should be evaluated only against an MKX already running 22-inch wheels or a confirmed wheel setup change.
The covered 2015 Lincoln Trucks MKX sub-model is straightforward in name, but fitment still requires attention because the Base model uses three different radial tire sizes. Checking the actual wheel diameter on the vehicle matters more than the trim badge when selecting a replacement.

Frequently Asked Questions
Common questions for the 2015 Lincoln Trucks MKX usually center on identifying the correct tire size for the wheel diameter, understanding the three radial fitments, and checking wheel, suspension, and tire condition before regular road use.
Tire Size & Fitment
What tire size fits a 2015 Lincoln Trucks MKX?
The 2015 Lincoln Trucks MKX uses three primary tire sizes: 245/60R18, 245/50R20, and 265/40R22. All three are radial sizes, and each one corresponds to a different wheel diameter rather than a different tire construction style.
The correct choice depends on the wheels actually installed on the vehicle. An MKX wearing 18-inch wheels needs 245/60R18, a 20-inch setup uses 245/50R20, and a 22-inch setup uses 265/40R22. Checking the sidewall of the current tire and confirming the wheel diameter before replacement helps avoid selecting the right profile in the wrong rim size.
What size rim does a 2015 Lincoln Trucks MKX use?
A 2015 Lincoln Trucks MKX can use 18-inch, 20-inch, or 22-inch rims, depending on the tire size installed. The three matching pairings are 245/60R18 on an 18-inch rim, 245/50R20 on a 20-inch rim, and 265/40R22 on a 22-inch rim.
Rim diameter is the first fitment point to verify because none of these tire sizes cross over to a different wheel diameter. A quick visual estimate is not enough on a vehicle that may have seen wheel changes. Reading the existing tire size and measuring or confirming the wheel specification is the safest way to match the replacement tire to the MKX’s actual setup.
Why does the 2015 Lincoln Trucks MKX have more than one tire size?
The 2015 Lincoln Trucks MKX has more than one tire size because it was fitted with different wheel diameters. The three primary fitments are 245/60R18, 245/50R20, and 265/40R22, all of which are radial tires matched to 18-inch, 20-inch, or 22-inch wheels.
That variety does not mean all three sizes are interchangeable on the same wheel. It means the vehicle can appear in different wheel-and-tire packages, and replacement selection has to follow the specific wheels on the MKX in front of you. If the crossover has aftermarket wheels or a previous owner changed the package, verify the current setup rather than assuming a trim-level default.
Choosing the Right Tire
What should I consider when choosing a tire for a 2015 Lincoln Trucks MKX?
Start with the correct primary size for the wheel diameter on the vehicle: 245/60R18, 245/50R20, or 265/40R22. Since all three fitments are radial, the core decision is not bias-ply versus radial but choosing a replacement that matches the existing wheel package and the vehicle’s intended use.
Beyond size, compare overall tire condition goals such as everyday road use, ride preference, and whether the MKX still carries its original-style wheel package or a later change. It also helps to confirm the wheel width, inspect for prior modifications, and make sure replacement tires leave proper clearance at full steering lock and through normal suspension travel.
How do I choose between the available 2015 Lincoln Trucks MKX tire sizes?
Choosing between the available 2015 Lincoln Trucks MKX tire sizes comes down to which wheels are on the vehicle. The 18-inch setup uses 245/60R18, the 20-inch setup uses 245/50R20, and the 22-inch setup uses 265/40R22. Those are separate fitments, not optional versions of the same tire for one wheel.
A useful way to decide is to treat the current wheel package as the starting point unless the vehicle is being intentionally reconfigured. Once the rim diameter is confirmed, stay within the matching size rather than chasing a similar-looking number. That keeps the replacement process focused on proper bead seating, sidewall profile, and real-world clearance on the MKX.
What rim-fitment details matter when choosing 2015 Lincoln Trucks MKX tires?
The most important rim-fitment detail on a 2015 Lincoln Trucks MKX is diameter. Each primary tire size is tied to a specific wheel size: 18, 20, or 22 inches. A 245/60R18 cannot be mounted on a 20-inch wheel, and a 245/50R20 cannot be mounted on an 18-inch wheel.
Wheel width and the actual setup on the vehicle matter too, especially if the MKX has aftermarket wheels. Diameter gets the tire onto the wheel, but width and offset affect how the tire sits and whether clearance remains acceptable. Checking both the wheel specification and the current tire sidewall before replacement helps avoid fitment surprises after installation.
Restoration & Appearance
Does correct tire fitment matter for a 2015 Lincoln Trucks MKX restoration or clean-stock appearance?
Yes, correct tire fitment matters even on a modern luxury crossover like the 2015 Lincoln Trucks MKX. Using the proper size for the wheel package keeps the vehicle’s stance, sidewall shape, and overall presentation consistent with the setup it is meant to carry, whether that is 18-inch, 20-inch, or 22-inch fitment.
Appearance issues often begin when a tire is installed on the wrong wheel diameter or when a previous modification changes the visual balance of the vehicle. Buyers aiming for a clean, stock-style presentation should confirm the current wheel package first, then match the appropriate radial size so the MKX looks properly proportioned rather than over- or under-tired.
Which tire size suits the intended look of a 2015 Lincoln Trucks MKX?
The intended look of a 2015 Lincoln Trucks MKX depends largely on which wheel package the vehicle wears. A 245/60R18 setup presents more sidewall, 245/50R20 moves to a lower-profile look, and 265/40R22 delivers the broadest, most wheel-dominant appearance among the three primary radial sizes.
That does not make one size universally better than another. It means the visual character changes with the wheel-and-tire package, so the best choice is usually the size that matches the wheels already on the vehicle. Anyone returning an MKX to a stock-style appearance should verify the wheel setup before choosing a replacement based mainly on looks.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 Lincoln Trucks MKX?
Yes, modifications can affect tire fitment on a 2015 Lincoln Trucks MKX. Wheel changes, altered offset, suspension lowering, replacement springs, and body changes can all influence which tire size clears properly, even when the sidewall number looks close to one of the vehicle’s original radial fitments.
A modified MKX should be checked at the wheel and fender, not just by catalog size. Steering clearance, inner wheelhouse space, and suspension travel all matter once the factory setup changes. Verifying the actual wheel diameter and examining how the current tires sit in the wheel openings can prevent selecting a replacement that creates rubbing or stance issues.
What should I inspect before driving a 2015 Lincoln Trucks MKX on new tires?
Before driving a 2015 Lincoln Trucks MKX on new tires, confirm that the size matches the wheel diameter and that the tires are seated properly on the rims. It is also wise to inspect the wheels themselves for damage, verify inflation pressure, and make sure the tires clear the body and suspension through normal steering movement.
A road-ready check should include looking at the old setup for signs of uneven wear, which can hint at alignment or suspension issues that new tires will not fix by themselves. The first miles are also a good time to stay alert for vibration, pull, or rubbing, since those symptoms can reveal wheel or fitment problems quickly.
How often should tires on a 2015 Lincoln Trucks MKX be inspected?
Tires on a 2015 Lincoln Trucks MKX should be inspected regularly, not only at replacement time. Routine checks for tread wear, cuts, punctures, bulges, air loss, and sidewall damage help catch problems early, especially on a vehicle that may alternate between daily use and longer parked periods.
Inspection matters just as much after the correct size has been chosen. A monthly pressure check, periodic tread review, and a quick look at shoulder wear can reveal alignment or suspension concerns before they become expensive. Vehicles with 20-inch or 22-inch wheel packages also benefit from close curb-damage checks because wheel and tire condition go hand in hand.
