2017 Lincoln Trucks Tire Fitment Guide

2017 Lincoln Trucks uses 11 sizes across four models. The MKC uses 235/50R18, 235/45R19, 245/45R19, and 255/40R20; the MKT uses 235/55R19 and 255/45R20; the MKX uses 245/60R18, 245/50R20, and 265/40R21; and the Navigator uses 275/55R20 and 285/45R22. These are all radial sizes, but they do not share one common rim diameter across the full lineup.

That means year and make alone are not enough for a correct tire choice on 2017 Lincoln Trucks. Start by identifying the model, then confirm whether the vehicle has 18-, 19-, 20-, 21-, or 22-inch wheels before comparing products. Even within one model, Lincoln often offered more than one wheel package, so the tire size on the sidewall or the factory door-jamb information is the best practical starting point.

On a 2017 Lincoln Trucks application, 235/50R18 is a metric radial size. The 235 is the section width in millimeters, 50 is the aspect ratio, the R indicates radial construction, and 18 is the wheel diameter in inches. On this year and make, that size belongs to the MKC rather than being shared across every Lincoln truck or SUV in the range.

Understanding that code helps you separate a true 18-inch MKC fitment from other Lincoln sizes that may look close but mount on different wheels or carry different sidewall proportions. It also helps when comparing products within the same size, because a 235/50R18 can come from different brands while still preserving the same basic dimensional format required by the vehicle.

No, 2017 Lincoln Trucks models do not use the same tire size. The compact MKC, three-row MKT, mid-size MKX, and full-size Navigator each have their own fitment groups, and several of those models use more than one wheel diameter. The overall spread runs from 18-inch applications up to 22-inch applications, so there is no single size that covers the entire 2017 Lincoln Trucks range.

That difference matters because a tire that fits one Lincoln utility model may be completely wrong for another, even when both are from the same year. If you are unsure, verify the model name first and then match the wheel diameter already on the vehicle. Once those two points are confirmed, choosing among available tire brands and sidewall styles becomes much more straightforward.

2017 Lincoln Trucks tire offerings here are predominantly Blackwall, with an RWL option also available in 255/45R20 for the MKT. The 245/45R19, 255/40R20, and 235/50R18 selections use Blackwall styling, while 255/45R20 can be found in either Blackwall or raised white letter form depending on the product line.

For most 2017 Lincoln luxury crossovers and SUVs, Blackwall is the cleaner and more factory-like visual choice. An RWL tire changes the appearance more noticeably and may appeal to buyers who want a sportier aftermarket look rather than a subdued luxury presentation. Sidewall style does not replace fitment verification, so confirm the correct size first and then choose the appearance that best suits the vehicle’s character.

BFGoodrich, Nitto, and Pro-Trac all appear in 2017 Lincoln Trucks fitments. The 245/45R19 size is available from BFGoodrich and Nitto, 255/40R20 is available from BFGoodrich, 235/50R18 is available from BFGoodrich and Nitto, and 255/45R20 is available from BFGoodrich, Nitto, and Pro-Trac. All of those offerings are radial tires.

That gives buyers some room to choose between established performance-oriented product families while staying within the proper size for their model. Brand choice becomes most useful after the correct model and wheel diameter have been confirmed, because the broader Lincoln range does not share one interchangeable size. Once fitment is settled, you can narrow the choice by sidewall style, speed rating, and overall product character.

For 2017 Lincoln Trucks fitments where both appear, BFGoodrich g-Force Comp 2 A/S and Nitto NT555 G2 share the same radial construction and Blackwall look, but they differ in details such as weight, load specification, and fitment coverage by size. In 245/45R19, the BFGoodrich g-Force Comp 2 A/S weighs 29 pounds while the Nitto NT555 G2 weighs 29.65 pounds. In 235/50R18, the BFGoodrich g-Force Comp 2 A/S weighs 29 pounds while the Nitto NT555 G2 weighs 27.86 pounds and carries a 1,819-pound load figure at 50 psi.

Those distinctions matter most when you are comparing products within one exact size rather than across different Lincoln models. If your priority is preserving the vehicle’s specified dimensions, stay within the correct size first and then compare the series details that matter to you, such as load capacity, rim-width compatibility where published, and the overall style of tire you prefer for the way the vehicle is driven.

Published rim-width ranges are available for several 2017 Lincoln Trucks sizes. The 235/50R18 tires fit rims from 6.5 to 8.5 inches wide, the 245/45R19 tires fit 7.5 to 9.0 inches wide, the 255/45R20 tires fit 8.0 to 9.5 inches wide, and the 255/40R20 tire fits 8.5 to 10.0 inches wide. Those ranges apply to the specific tire sizes, not to every 18-, 19-, or 20-inch Lincoln wheel automatically.

Rim width is worth checking because two tires may share the same wheel diameter but still prefer different wheel widths for proper profile and support. If your 2017 Lincoln Trucks model uses one of these sizes, verify the actual wheel width before finalizing a tire choice, especially when replacing factory wheels with aftermarket ones or when comparing products across multiple fitments offered within the same model.

The available 2017 Lincoln Trucks products here are modern radial designs without tube-type markings, and none of these fitments indicate a tube-required construction. That points toward tubeless use for the available 245/45R19, 255/40R20, 235/50R18, and 255/45R20 product lines. Lincoln’s 2017 crossover and SUV platforms were built in the modern tubeless era rather than around vintage tube-type wheel practice.

The practical step is to confirm the actual wheel condition and valve-stem setup before installation. A damaged bead seat or compromised valve stem can cause air-loss issues even with the correct tubeless tire. If the vehicle has replacement wheels, have the wheel inspected as closely as the tire size itself, since correct sizing does not compensate for a wheel that is no longer sealing properly.

A 2017 Lincoln Trucks vehicle stores best in a cool, dry, dark space away from direct sunlight, electric motors, welders, furnaces, or other ozone-producing equipment that can age rubber prematurely. Keep the tires properly inflated during storage, and avoid leaving the vehicle parked for long periods on wet ground or in areas with major temperature swings. Radial tires generally tolerate storage better than older bias-ply designs, but they still benefit from periodic movement.

If the vehicle will sit for months, roll it occasionally to change the contact patch or place it on stands if storage conditions and suspension support allow. That helps reduce long-term stress in one spot of the tread and sidewall. For a luxury SUV or crossover that may see seasonal use, careful storage does as much for tire longevity as choosing the right brand in the first place.

On a 2017 Lincoln Trucks vehicle, tire age is usually more important than mileage alone, especially if the vehicle is driven occasionally. A sound rule is to begin evaluating tires closely around five to seven years of age and to treat the ten-year point as a serious replacement threshold regardless of remaining tread. The DOT date code on the sidewall is the clearest way to confirm the tire’s actual age.

That matters because a lightly driven luxury SUV can still age its tires out before wearing them out. Sidewall weathering, internal aging, and long periods of inactivity can reduce confidence even when tread depth still looks usable. If a 2017 Lincoln Trucks model spends more time parked than driven, age-based inspection is the right maintenance habit rather than waiting for mileage alone to dictate replacement.

Tires on a 2017 Lincoln Trucks should be checked before every drive and again before any longer highway trip. Look for cracking, cuts, bulges, irregular wear, punctures, and pressure loss, and make sure the tread is wearing evenly across the tire. Because these are modern tubeless radial fitments, valve stems and bead sealing condition deserve attention along with the tread and sidewalls.

Regular inspection is especially important on a vehicle that alternates between short local use and occasional long trips, since low annual mileage can hide age-related issues. A quick walkaround catches many problems early, while a more detailed inspection a few times a year helps identify alignment or suspension wear that may show up first through the tires. Tires often provide the earliest warning that a larger chassis issue needs attention.

Yes, the available 2017 Lincoln Trucks products shown here are modern radial tires intended for normal road use, and several carry substantial speed capability. The visible speed ratings are W and Y, with W approved to 168 mph and Y approved for 186 mph and above. Those ratings are well beyond ordinary highway speeds, so in real-world use the condition of the tire, correct inflation, and the vehicle’s own suspension and braking condition matter more than raw speed ceiling.

Safe highway use still depends on matching the correct size to the exact model and wheel diameter, because an otherwise high-quality tire is not safe if it is the wrong fitment. Before a trip, verify pressure, inspect for visible aging or damage, and make sure the tires are wearing evenly. On a heavy luxury SUV like a Navigator, carrying capacity and overall condition deserve just as much attention as speed rating.

Inflation pressure for 2017 Lincoln Trucks should follow the vehicle manufacturer’s recommendation first, with the tire’s own maximum-pressure marking used as a tire-capacity reference rather than a blanket operating target. Among the available products here, 235/50R18 appears with load figures such as 1,609 at 51 psi and 1,819 at 50 psi; 245/45R19 reaches 1,874 pounds at 50 psi; 255/40R20 reaches 1,819 pounds at 50 psi; and 255/45R20 appears at 1,819 at 51 psi on one product.

Those figures should not be transferred from one size to another or from one Lincoln model to the next. The practical approach is to use the factory placard or owner’s manual for everyday inflation, then confirm that the chosen tire’s load capability suits the vehicle at that pressure. If you are changing product lines within the same size, review the sidewall markings instead of assuming every tire in that size uses the same pressure relationship.

Before a longer trip in a 2017 Lincoln Trucks vehicle, inspect all four tires for cracking, cuts, bulges, punctures, uneven wear, and proper cold inflation pressure. Check the valve stems, confirm the spare is usable, and make sure tread depth is consistent enough for wet-weather confidence. A long-drive inspection should also include a quick look at alignment clues such as feathering or one-sided wear, since those issues often show up first through the tires.

Tires are only one part of the pre-trip checklist on a vehicle of this type, so it is wise to pair that inspection with a review of brakes, suspension, fluids, battery condition, and lights. On 2017 Lincoln Trucks models that use larger 20-, 21-, or 22-inch wheel packages, a curb-damaged wheel or tire sidewall deserves extra scrutiny. Catching a small issue in the driveway is much easier than dealing with it on the road.
