2014 Lincoln Tire Fitment Guide

2014 Lincoln vehicles use four tire sizes across two models: 245/45R20 and 255/45R19 for the Lincoln MKS, plus 245/40R19 and 245/45R18 for the Lincoln MKZ. All four are radial sizes, but they do not share one common wheel diameter. The MKS spans 19-inch and 20-inch applications, while the MKZ spans 18-inch and 19-inch applications.

That means year and make alone are not enough to choose correctly. Start with the model, then confirm the wheel diameter on the car before moving to a specific tire. Rim-width guidance also varies by size where product coverage exists: 245/45R20 generally fits 7.5- to 9.0-inch rims, 245/40R19 fits 8.0- to 9.5-inch rims, and 245/45R18 fits 7.5- to 9.0-inch rims.

On a 2014 Lincoln tire, 245/45R20 means the tire is 245 millimeters wide, has a 45-series aspect ratio, uses radial construction, and mounts on a 20-inch wheel. That size appears on the Lincoln MKS, not across the full 2014 Lincoln range. Available versions carry W and Y speed ratings, which correspond to 168 mph and 186+ mph ceilings.

For an MKS owner, the important takeaway is that 245/45R20 is tied to the 20-inch wheel package. It is not interchangeable with the MKS 255/45R19 option or the MKZ sizes unless the wheel itself matches. Confirm the tire placard or the current wheel diameter on the car before choosing among BFGoodrich and Nitto offerings in this size.

No. 2014 Lincoln models do not use the same tire size. The MKS uses either 245/45R20 or 255/45R19, while the MKZ uses either 245/40R19 or 245/45R18. Even where two models share a 19-inch wheel diameter in some configurations, the tire dimensions are still different.

That variation matters because a tire that fits one 19-inch Lincoln application may still be wrong for another. Sidewall height, section width, and approved rim-width range can all change with the size code. If you are comparing cars in the same year and make, identify the model first, then match the exact size on the door placard or the existing tire before narrowing down brand or tread choice.

The available 2014 Lincoln tire choices on this page use Blackwall sidewalls across the covered sizes. That applies to 245/45R20 for the MKS, 245/40R19 for the MKZ, and 245/45R18 for the MKZ. These are modern radial products aimed at late-model luxury sedan fitments rather than vintage whitewall presentation.

For a 2014 Lincoln buyer, sidewall styling is less about period restoration accuracy and more about matching the car’s original contemporary look. Blackwall tires keep the appearance clean and understated, which suits both the MKS and MKZ. Once the sidewall style is settled, the more important decision becomes selecting the correct size and then comparing the available BFGoodrich and Nitto products within that size.

BFGoodrich and Nitto cover the available 2014 Lincoln tire sizes on this page. The 245/45R20 MKS size is available from both BFGoodrich and Nitto, the 245/40R19 MKZ size is covered by BFGoodrich, and the 245/45R18 MKZ size is available from both BFGoodrich and Nitto. All of these are radial Blackwall tires.

Brand choice becomes most meaningful after you confirm the exact size your car uses. Some sizes offer a broader mix of product lines, while others stay within one brand family. If you are deciding between options, compare speed rating, load capacity where shown, and approved rim-width range rather than assuming the same construction name or brand automatically means the same fit or road feel.

For the covered 2014 Lincoln sizes, BFGoodrich g-Force Sport Comp 2 and BFGoodrich g-Force Phenom T/A overlap in fitment but differ in some published details. In 245/45R20, the Sport Comp 2 carries a 103W rating and 1,930-pound max load at 50 psi, while the Phenom T/A carries a 103Y rating and 1,929-pound max load at 50 psi. In 245/40R19, the Sport Comp 2 is 98W with a 1,653-pound max load at 50 psi, while the Phenom T/A is 98Y with the same 1,653-pound load figure.

That comparison shows the practical difference is not basic fitment, since both lines cover the same wheel diameter and rim-width range within those sizes. The distinction is more about the exact speed rating and the specific product line you prefer. When choosing between them, make sure you are comparing within the same tire size first, then weigh the W-versus-Y speed category and any other product-level details important to your use.

Rim-width guidance for 2014 Lincoln tires varies by size. The 245/45R20 used on the MKS fits 7.5- to 9.0-inch rims, the 245/40R19 used on the MKZ fits 8.0- to 9.5-inch rims, and the 245/45R18 used on the MKZ fits 7.5- to 9.0-inch rims. Those ranges are tied to the tire size itself, not simply to the Lincoln badge or model year.

If you are replacing tires on factory wheels, staying with the same size usually keeps you within the intended width range. If the car has aftermarket wheels or a changed wheel package, verify actual wheel width before selecting a tire. A size may share the same rim diameter as another option on the car, but that does not make the approved rim-width range identical.

The available 2014 Lincoln tire products on this page are modern radial designs and include tubeless markings where that information appears, such as the 245/45R20 BFGoodrich g-Force Comp 2 A/S marked TL. Across these late-model radial applications, the fitment is consistent with tubeless passenger-car use rather than tube-type collector construction. None of the covered sizes are presented as dedicated tube-type fitments.

That said, wheel condition still matters. If a 2014 Lincoln has damaged bead seats, corrosion, or non-original wheels, those issues should be corrected before mounting any replacement tire. Treat the tire’s sidewall marking and the wheel’s condition as the final authority, especially if the car has had wheel changes or has been stored for a long period before returning to service.

A 2014 Lincoln should be stored in a cool, dry, dark space away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment. Keep the tires properly inflated, and if the car will sit for an extended period, move it occasionally to avoid long-term stress on one contact patch. These are radial tires, so they generally tolerate storage better than older bias-ply designs, but neglect still shortens tire life.

For seasonal or collector use, clean the tires, check pressures regularly, and avoid leaving the car parked on damp ground. If the vehicle will sit for many months, some owners use tire cradles or lift the car slightly to reduce static loading. Storage habits matter just as much as miles driven on a low-use luxury sedan like a 2014 Lincoln.

Tires on a 2014 Lincoln should be judged by age as much as by wear. A good rule is to begin close evaluation once a tire reaches roughly five to seven years old and to treat around ten years as a serious replacement point regardless of remaining tread. The DOT date code on the sidewall is the key reference for age, especially on a car that may not accumulate high annual mileage.

Luxury sedans that see occasional use can hide tire aging because the tread may still look deep. That makes sidewall condition, hardening, and age especially important when evaluating an MKS or MKZ. Even if the car feels fine on short local drives, older tires deserve a careful review before interstate travel or sustained highway use.

Tires on a 2014 Lincoln should be inspected before every drive and more thoroughly before any longer trip. Check for cracking, cuts, bulges, uneven tread wear, punctures, and pressure loss. Because these are modern radial sizes, also pay attention to wear patterns that can point to alignment or suspension issues rather than tire age alone.

A quick walkaround is enough for routine use, but a hands-on inspection becomes more important when the car has been sitting. Look at the inner sidewall if possible, confirm valve stem condition, and verify that the spare is still serviceable. Catching a problem early is especially valuable on a premium sedan, where quiet road manners can sometimes mask a tire issue until it becomes more serious.

The 2014 Lincoln MKS came from the factory era of modern radial passenger-car tires, not vintage bias-ply construction. Within this year and make, the MKS uses either 245/45R20 or 255/45R19 depending on the wheel package. That means originality starts with matching the correct modern metric radial size to the specific car rather than choosing an antique-style construction.

For an accurate restoration or preservation-minded replacement, confirm the original size from the door placard, owner’s literature, or the car’s original wheel package before selecting a tire. Since wheel and trim combinations can affect which of the two MKS sizes applies, marque specialists and Lincoln forums can help verify what belongs on a particular car if its wheels have been changed over time.

Yes, correct tire fitment matters when showing a 2014 Lincoln, even though it is a newer collector-era vehicle. Judges and knowledgeable enthusiasts will notice if an MKS or MKZ wears the wrong diameter, incorrect overall profile, or a size that does not match the car’s factory wheel package. On a 2014 vehicle, authenticity usually centers on proper modern metric radial sizing and an era-appropriate Blackwall appearance.

The practical point is that authenticity for a 2014 Lincoln is more subtle than for a mid-century collector car. You are less likely to be judged on wide whitewalls or bias-ply details and more likely to be judged on whether the wheel-and-tire package looks factory-correct. Event standards vary, so check the rules of the club or show where the car will be judged.

For 2014 Lincoln fitments where both appear, BFGoodrich g-Force Comp 2 A/S and Nitto NT555 G2 share the same basic wheel diameter within a given size but differ in their published details. In 245/45R18, the BFGoodrich g-Force Comp 2 A/S is a 96W tire, while the Nitto NT555 G2 is a 100W XL tire with a 1,764-pound max load at 50 psi. In 245/45R20, the Nitto NT555 G2 is a 103W XL tire, while the BFGoodrich all-season option carries a 103Y designation.

For a 2014 Lincoln owner who wants a factory-correct overall look, both remain modern Blackwall radial choices. The distinction is in the exact load and speed specification, plus the individual product line itself. Compare them within the same tire size only, because the 18-inch MKZ fitment and 20-inch MKS fitment serve different wheel packages and should not be mixed when judging authenticity or selecting replacements.

Yes, the available 2014 Lincoln tire sizes are modern radial highway-capable designs, and the covered products carry W and Y speed ratings. W corresponds to 168 mph, while Y corresponds to 186+ mph. Those figures are far beyond normal U.S. highway speeds, so in everyday use the limiting factor on a 2014 Lincoln is more likely to be tire age, inflation, alignment, or the car’s overall mechanical condition than the speed symbol itself.

That does not mean any old tire is automatically roadworthy. A worn, cracked, or underinflated tire remains a risk even if the original speed rating was high. For a luxury sedan like the MKS or MKZ, highway confidence comes from the right size, sound condition, proper pressure, and a suspension and brake system that are in equally good order.

Inflation pressure for 2014 Lincoln tires should follow the vehicle manufacturer’s recommendation for the exact model and size, with the tire’s own sidewall figures understood as maximum load-at-pressure ratings rather than default operating pressures. Among the available products, examples include 1,930 pounds at 50 psi for 245/45R20, 1,653 pounds at 50 psi for 245/40R19, and 1,764 pounds at 50 psi for some 245/45R18 applications.

Those numbers should not be transferred from one size to another or treated as the everyday cold pressure for every MKS or MKZ. The safe approach is to use the door placard or owner’s manual for the car’s intended operating pressure, then confirm that the replacement tire’s rating meets the application. That keeps the tire working within its design range without overgeneralizing from a max-load figure.

Before a longer drive in a 2014 Lincoln, inspect all four tires for cracks, cuts, punctures, bulges, irregular tread wear, and correct cold inflation pressure. Make sure the size on the car matches the wheel package it is mounted on, especially if the vehicle has changed hands or has aftermarket wheels. Check the spare as well, since an aged or neglected spare can turn a small problem into a trip-ending one.

Tires are only one part of the pre-drive checklist on a modern collector-era Lincoln. It is wise to confirm brake condition, fluid levels, battery health, and suspension feel before committing to a long highway trip. Starting with a careful tire inspection helps you catch the most common problems early, but the best road-trip preparation looks at the entire car as a system.
