Lincoln MKS Tires

Lincoln MKS uses three tire sizes across the 2009 to 2016 production run: 235/55R18 for 2009 through 2012, 255/45R19 for 2009 through 2016, and 245/45R20 for 2009 through 2016. Each size corresponds to a different wheel diameter, so the 235/55R18 fits 18-inch wheels, the 255/45R19 fits 19-inch wheels, and the 245/45R20 fits 20-inch wheels. All three are metric radial sizes rather than older numeric or alphanumeric collector-car formats.

That means there is no single tire size that fits every Lincoln MKS. The practical first step is to verify the wheel diameter actually on the car, then match the tire size to that wheel. If the car has changed hands, has aftermarket wheels, or has had a wheel package swap during its life, use the placard, wheel markings, and current tire size together before making a final selection.

A 2009 Lincoln MKS has three sizes listed because that model year was offered with more than one wheel and tire package. The listed choices are 235/55R18, 255/45R19, and 245/45R20, which means the split is tied to different rim diameters rather than one interchangeable setup. The same pattern also appears in 2010, 2011, and 2012 Lincoln MKS applications.

Year alone is not enough when a Lincoln MKS falls into one of those multi-size years. The safest approach is to identify the wheel diameter on the actual car first, then confirm the size molded on the current tire if the car is still wearing the correct wheel package. That keeps you from accidentally choosing a tire that is dimensionally correct on paper but wrong for the wheel installed on the car.

Lincoln MKS uses three rim diameters within this year range: 18 inches, 19 inches, and 20 inches. The 18-inch fitment appears with 235/55R18 from 2009 through 2012, while 19-inch and 20-inch fitments appear across 2009 through 2016 with 255/45R19 and 245/45R20. There is no antique-size decoding involved here, because the final number in each metric size is the wheel diameter in inches.

For a Lincoln MKS owner, that makes wheel confirmation the most important fitment step. Read the wheel diameter directly from the tire size or the wheel itself before comparing products. If a car has been upgraded or altered, the current wheel package matters more than assumptions tied to trim level, because an 18-inch tire will not substitute for a 19- or 20-inch fitment.

A 2014 Lincoln MKS uses either 255/45R19 or 245/45R20, so the correct size depends on which wheel package is on the car. Both are radial tires, but they are built for different rim diameters and are not interchangeable. A 2014 Lincoln MKS does not use the earlier 235/55R18 size that appears on some 2009 through 2012 cars.

Start with the current tire sidewall and the wheel diameter, then cross-check the door placard if it is still present. If the car has been fitted with replacement wheels, rely on the actual wheel and tire combination rather than the assumption that all 2014 Lincoln MKS sedans used the same setup. That simple check usually resolves the fitment question before you compare tread style or brand.

The available Lincoln MKS products in 245/45R20 include Blackwall, Redline, and RWL sidewall styles. Blackwall is represented across several radial performance tires, while the Pro-Trac Street Pro III is offered in both Redline and raised white letter form. Those are appearance variations within the same 20-inch size rather than changes to the required rim diameter.

Sidewall style lets a Lincoln MKS owner lean more toward understated modern luxury or a more personalized visual treatment. Blackwall usually gives the most subdued look, while Redline or RWL creates a more distinctive profile. Once the correct size and wheel diameter are settled, sidewall style becomes a useful finishing choice rather than a fitment concern.

The available Lincoln MKS products here come from BFGoodrich, Nitto, and Pro-Trac. All listed products are in the 245/45R20 size, and all are radial-construction tires. BFGoodrich appears in multiple series, while Nitto and Pro-Trac add alternative tread and appearance choices within the same fitment.

Brand comparison matters after the size question is settled. A Lincoln MKS owner with 20-inch wheels can then choose among different brand personalities, sidewall looks, and tire series without changing the core fitment. If the car uses 18-inch or 19-inch wheels, begin with the correct size first and treat these 20-inch brand options as wheel-package-specific rather than universal MKS choices.

The Lincoln MKS products shown in 245/45R20 include several distinct series: g-Force Sport Comp 2, g-Force Comp 2 AS, Nitto NT555 G2, g-Force Phenom T/A, and Street Pro III. All are radial tires, but they represent different product families rather than one repeated casing with different branding. Street Pro III also appears with multiple sidewall styles, including Redline and RWL.

For a Lincoln MKS owner, those differences are most useful when refining the look and character of a 20-inch setup. Once fitment is confirmed, the series choice helps determine whether you want a more conventional blackwall presentation or something more visually distinctive. The important boundary is that series selection comes after size confirmation, because none of those series changes the need for a 20-inch wheel on this fitment.

A stored Lincoln MKS benefits from a clean, dry, dark environment with stable temperatures and minimal exposure to sunlight, ozone, or electric motors that can accelerate rubber aging. Keep the tires properly inflated for the wheel package on the car and avoid leaving the car parked for long periods on underinflated tires, which can promote flat-spotting and sidewall stress. Clean tires with mild soap and water rather than dressings that can leave residue on the rubber.

If a Lincoln MKS will sit for an extended period, rolling it occasionally or using storage cradles can help reduce prolonged contact stress. Owners who maintain multiple wheel sets should label each set clearly so the correct 18-, 19-, or 20-inch package goes back on the right car. Good storage habits preserve ride quality and make your next inspection much more meaningful.

Tires on a Lincoln MKS should be inspected regularly even if the car is not driven often. Look for cracking, bulges, punctures, uneven shoulder wear, center wear from inflation problems, and any signs that one tire size has been mixed into a wheel package where it does not belong. Because Lincoln MKS uses multiple possible wheel diameters, inspection also includes confirming that all four tires match the intended fitment.

A practical routine is to check the tires before any longer drive and at regular seasonal intervals during lower-use periods. Inspection is also the best time to compare sidewall markings, load information, and wheel diameter so mismatched replacements are caught early. Catching age or wear issues before they become visible failures is especially important on a heavier luxury sedan like the Lincoln MKS.

Tires on a Lincoln MKS should be replaced when age-related deterioration, impact damage, bulges, persistent vibration, repeated air loss, or structural cracking appear, even if the tread still looks usable. Collector-minded owners sometimes focus on tread depth alone, but rubber condition and casing health matter just as much as visible wear. Any tire that shows clear sidewall fatigue or has an uncertain service history deserves close attention.

For a Lincoln MKS that sees occasional use, replacement decisions should be driven by condition, age, and confidence at highway speeds rather than mileage alone. If a tire has been on the car through long storage cycles or temperature swings, have it evaluated during routine service. Replacing aging tires before they become a road-use problem protects the car’s ride quality and reduces the risk of damaging a wheel or suspension component.

Lincoln MKS appears with three fitment sizes across its production run: 235/55R18, 255/45R19, and 245/45R20. Those sizes align with different wheel packages used during 2009 through 2016 rather than a single original tire specification for every car. The available 20-inch products are all modern radial tires, which is consistent with the era and character of the MKS as a contemporary luxury sedan.

For an owner interested in preserving originality, the goal is to match the tire size to the specific wheel package the car carried when new. Window stickers, build records, original photographs, and marque-focused owner communities can help confirm that detail when a car has had wheels replaced over time. Authenticity on a Lincoln MKS is more about correct size and visual presentation than older-style construction categories.

Correct tire fitment matters on a Lincoln MKS because wheel diameter and tire profile shape the car’s stance, proportions, and overall presentation. A car shown with the wrong 18-, 19-, or 20-inch fitment can look immediately off to an informed observer, even before any driving impression enters the picture. On a newer collector sedan, accuracy often means preserving the intended wheel-and-tire relationship rather than chasing a generic replacement size.

For owners thinking about long-term value, matching the proper tire size to the car’s wheel package supports both appearance and credibility. If a Lincoln MKS is being prepared for enthusiast events, retain records of the wheel package and size choice so future owners understand what was fitted and why. Small details like sidewall style can also influence how original or personalized the car appears.

The available Lincoln MKS 245/45R20 products include Blackwall, Redline, and RWL sidewall styles. Blackwall is the most restrained and factory-like appearance among the listed options, while Redline and raised white letters create a more customized visual statement. All three choices keep the same 20-inch fitment, so the difference is primarily aesthetic rather than dimensional.

For a restoration-minded Lincoln MKS owner, Blackwall will usually be the closest match to the understated luxury tone the model carried when new. Redline or RWL can still be attractive choices if the car is being personalized rather than preserved in a stock visual theme. Once the correct size is established, sidewall style becomes one of the easiest ways to steer the final look of the car.

A Lincoln MKS can be safely driven on public roads when the tires are the correct size for the wheel, are in sound condition, and are matched as a complete set where appropriate. The listed MKS sizes are modern radial fitments, and the available 245/45R20 products are all radial-construction tires intended for normal road use within their design category. Safety begins with correct fitment before any discussion of handling or appearance.

What matters in practice is avoiding mismatched wheel diameters, uneven tire conditions, or aged tires that no longer inspire confidence. Before road use, confirm inflation, inspect for visible damage, and make sure the car is not carrying an incorrect size because of an old replacement. A properly sorted Lincoln MKS should be treated like the substantial, modern luxury sedan it is, with roadworthiness checked at the tire level first.

Before driving a Lincoln MKS, check that all four tires match the intended size for the wheel package, then inspect inflation, tread condition, sidewalls, and valve stems. Because Lincoln MKS used 18-, 19-, and 20-inch wheel fitments, even one incorrect replacement tire can create avoidable handling or clearance issues. Also look for signs of impact damage, shoulder wear, or age cracking that may not be obvious when the car is parked casually in the garage.

A short pre-drive walkaround is usually enough to catch the biggest problems. If the car has sat for a while, pay extra attention to flat-spotting, slow air loss, and any vibration on the first few miles. That routine helps owners separate a normal storage-related issue from a tire that needs replacement before the Lincoln MKS returns to regular road use.

A Lincoln MKS should only be driven at speeds appropriate to the exact tire fitted, its condition, and the intended wheel package. The available 245/45R20 products include modern radial tires carrying performance-oriented markings, but safe real-world speed still depends on age, inflation, condition, and whether all four tires are properly matched. No speed capability should ever be assumed from size alone.

The practical takeaway is to treat a Lincoln MKS with fresh, correctly fitted tires very differently from one wearing older or uncertain rubber. Even if tread depth looks acceptable, age and storage history matter on a low-use car. Confirm the tire’s service condition first, then drive within the limits of the tire, the road, and the vehicle’s overall mechanical health.
