The 2010 Lincoln Trucks MKX blends luxury crossover comfort with the bolder wheel-and-tire styling that became increasingly common in premium utility vehicles of the period. Buyers looking at one today are often balancing everyday road use with the need to preserve the vehicle’s intended stance and appearance. Tire fitment on the 2010 Lincoln Trucks MKX is entirely radial, but the correct size depends on the wheel and sub-model configuration, with 245/60R18, 245/50R20, and 265/40R22 all in the picture. That makes wheel diameter the first checkpoint, especially on the sport suspension package. Once that is confirmed, the real choice is selecting the right profile and fitment for the way the vehicle is equipped.
Which Tire Size Is Right for The 2010 Lincoln Trucks MKX
Three tire sizes apply to the 2010 Lincoln Trucks MKX, and they are tied to different wheel diameters and sub-model configurations. The first step is confirming whether the vehicle is on 18-inch, 20-inch, or 22-inch wheels, then matching that to the exact MKX setup. Once the wheel size is verified, the decision shifts to choosing the right radial tire within that fitment rather than comparing unrelated sizes.
245/50R20 is a metric radial size in which 245 represents the section width in millimeters, 50 is the aspect ratio, R identifies radial construction, and 20 is the rim diameter in inches. On the 2010 Lincoln Trucks MKX, this size belongs to a 20-inch-wheel setup and keeps the fitment in a fully modern radial format. Its proportions place it close to the overall diameter of the 18-inch option while using a larger wheel. This is the size to evaluate when the vehicle is equipped with 20-inch wheels and you want to preserve the intended wheel-and-tire relationship.
245/60R18 is a metric radial size with a 245-millimeter section width, a 60-series aspect ratio, and an 18-inch rim diameter. For the 2010 Lincoln Trucks MKX, this size serves the 18-inch-wheel configuration and uses the same nominal width as the 20-inch alternative but with a taller sidewall profile. That makes the wheel diameter especially important, since the tire is not meant for the 20-inch or 22-inch setups. This fitment is the right one to consider when the vehicle remains on its 18-inch wheels and a stock-type overall stance is the goal.
265/40R22 is a metric radial size where 265 is the section width in millimeters, 40 is the aspect ratio, R indicates radial construction, and 22 is the wheel diameter in inches. On the 2010 Lincoln Trucks MKX, this size is tied to the w/Sport Suspension Pkg. configuration and stands apart from the other fitments by using both a wider tread section and a 22-inch rim. Its role is specific rather than interchangeable across the whole model line. This is the size to verify when the MKX has the sport package setup or already wears 22-inch wheels.
Sub-model fitment matters on the 2010 Lincoln Trucks MKX because tire size changes with wheel and suspension configuration. The Base model can use either of two radial sizes, while the w/Sport Suspension Pkg. moves to a separate 22-inch fitment that should be confirmed before selecting tires.

2010 Lincoln Trucks MKX Base
The 2010 Lincoln Trucks MKX Base uses radial tires and can be fitted with either an 18-inch or 20-inch wheel package. Tire selection starts with confirming which wheel diameter is on the vehicle, then choosing the matching size so the profile and overall fitment stay aligned with that setup.
The 2010 Lincoln Trucks MKX w/Sport Suspension Pkg. uses a distinct radial tire fitment built around a 22-inch wheel. That makes it especially important to confirm the sport-package wheel setup before replacing tires, since this size should not be confused with the Base model’s 18-inch or 20-inch configurations.
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 2010 Lincoln Trucks MKX usually come down to identifying the correct wheel diameter, sorting out Base versus sport suspension fitment, and choosing the right radial size for the vehicle’s current setup. These FAQs focus on size, rim fitment, selection, appearance, and practical road-use checks.
Tire Size & Fitment
What tire size fits a 2010 Lincoln Trucks MKX?
The 2010 Lincoln Trucks MKX uses three possible radial tire sizes: 245/60R18, 245/50R20, and 265/40R22. The Base model uses either 245/60R18 or 245/50R20, while the 2010 Lincoln Trucks MKX w/Sport Suspension Pkg. uses 265/40R22.
The key is matching the tire to the wheel package actually on the vehicle. An MKX that has been changed from its original wheel setup should be checked carefully before replacement, since the correct size depends on rim diameter first and sub-model configuration second.
What size rim does a 2010 Lincoln Trucks MKX use?
A 2010 Lincoln Trucks MKX can use 18-inch, 20-inch, or 22-inch rims depending on configuration. The 245/60R18 tire fits an 18-inch rim, the 245/50R20 fits a 20-inch rim, and the 265/40R22 fits a 22-inch rim.
Rim diameter is the most important fitment checkpoint on this vehicle because the three tire sizes are tied directly to three different wheel sizes. Checking the tire sidewall is helpful, but confirming the actual wheel on the vehicle avoids ordering a tire that matches the model name but not the installed setup.
Why does the 2010 Lincoln Trucks MKX have more than one tire size?
More than one tire size appears on the 2010 Lincoln Trucks MKX because fitment varies by wheel package and sub-model. The Base model can use either 245/60R18 or 245/50R20, while the w/Sport Suspension Pkg. uses a separate 265/40R22 size.
That means the model name alone is not enough to choose a replacement tire. The practical step is to confirm whether the vehicle is a Base or sport suspension package and then verify the installed wheel diameter, especially if the MKX has ever had wheel upgrades or cosmetic changes.
Choosing the Right Tire
What should I consider when choosing a tire for a 2010 Lincoln Trucks MKX?
Start with the exact tire size already tied to the wheel package on the vehicle, because the 2010 Lincoln Trucks MKX uses three different radial fitments. The decision begins with confirming whether the vehicle is on 18-inch, 20-inch, or 22-inch wheels and whether it is a Base model or the w/Sport Suspension Pkg.
After that, compare the tire’s intended role in the vehicle’s overall setup. Sidewall profile, wheel diameter, and the current ride-height or suspension condition all affect how the tire will suit the MKX, so replacement should follow the installed configuration rather than the model name alone.
How do I choose between the available 245/60R18 and 245/50R20 tires for a 2010 Lincoln Trucks MKX Base?
A 2010 Lincoln Trucks MKX Base does not use 245/60R18 and 245/50R20 interchangeably unless the wheel package matches the tire. The 245/60R18 belongs on an 18-inch rim, while the 245/50R20 belongs on a 20-inch rim, so the wheel size decides which one is correct.
Once the rim diameter is confirmed, the remaining choice is about preserving the vehicle’s existing setup. The 18-inch and 20-inch fitments have similar overall diameter, but they are built around different wheel sizes and sidewall proportions, so the installed wheel should guide the replacement decision.
How do I choose the right 265/40R22 tire for a 2010 Lincoln Trucks MKX?
The 265/40R22 size belongs to the 2010 Lincoln Trucks MKX w/Sport Suspension Pkg. and should be selected only when the vehicle is using that 22-inch setup. It is a modern metric radial size with a wider section and lower profile than the Base model’s 18-inch and 20-inch fitments.
Selection should focus on keeping the tire matched to the sport-package wheel diameter and the vehicle’s actual stance. A useful check includes wheel width, suspension condition, and fender or steering clearance, particularly if the MKX has aftermarket wheels or has been altered since new.
Restoration & Appearance
Which tire should I choose for a period-style 2010 Lincoln Trucks MKX?
A period-style choice for a 2010 Lincoln Trucks MKX starts with keeping the correct radial size for the vehicle’s original-type wheel package. That means 245/60R18 or 245/50R20 for a Base model, or 265/40R22 for the w/Sport Suspension Pkg., depending on how the vehicle is equipped.
Appearance on a modern luxury crossover is closely tied to wheel diameter and sidewall proportion, so preserving the intended visual balance usually matters more than searching for a vintage-style construction change. Owners pursuing exact originality should compare the current setup with vehicle-specific historical references before making a cosmetic change.
Does correct tire fitment matter for a 2010 Lincoln Trucks MKX restoration?
Correct tire fitment matters because the 2010 Lincoln Trucks MKX uses distinct wheel-and-tire combinations that shape both appearance and stance. An 18-inch, 20-inch, or 22-inch setup gives the vehicle a different visual character, so using the wrong size can change how the MKX sits and presents.
That is especially important on a restoration-minded vehicle where wheel package and profile help define the finished look. Matching the tire size to the actual sub-model and installed rim diameter is the best starting point, then finer details can be checked against photos, factory literature, or marque-specific references.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2010 Lincoln Trucks MKX?
Yes, modifications can affect tire fitment on a 2010 Lincoln Trucks MKX. Wheel changes, lowered suspension, altered ride height, or non-original offsets can all change the space available for 245/60R18, 245/50R20, or 265/40R22 tires, even when the tire size looks correct on paper.
A replacement tire should always be matched to the vehicle’s actual wheel and suspension setup rather than assumed from the badge alone. Clearance at full steering lock and through suspension travel is worth checking, especially on an MKX that has been fitted with larger custom wheels.
What should I inspect before driving a 2010 Lincoln Trucks MKX on new tires?
Before driving a 2010 Lincoln Trucks MKX on new tires, inspect the wheels for correct diameter and condition, confirm proper inflation, and make sure each tire matches the vehicle’s installed setup. It is also wise to look over alignment-related wear points, suspension condition, and brake clearance.
A short initial road check can reveal rubbing, vibration, or steering pull before the vehicle goes on a longer trip. Rechecking pressure after the first drive and confirming there is no contact at full turn helps ensure the new tires suit the wheel package and the condition of the MKX.
What should I check before a longer drive in a 2010 Lincoln Trucks MKX?
Before a longer drive, check tire pressure, tread condition, sidewall condition, and any signs of bulges, cuts, or slow air loss on the 2010 Lincoln Trucks MKX. Make sure the tire size matches the wheel diameter on the vehicle, particularly if it uses the 22-inch sport suspension fitment.
Longer highway use places more importance on stability and even wear, so a quick inspection of alignment behavior and suspension condition is worthwhile. Any MKX with older tires, aftermarket wheels, or recent wheel changes deserves an extra clearance check before putting serious road miles on it.
