The 2019 Lincoln MKZ sits in the final stretch of Lincoln’s midsize sedan era, blending modern luxury-sedan styling with a quieter, more refined road-going character than many sport-focused rivals. That makes tire choice especially important, because the MKZ’s ride, steering feel, and overall presentation depend heavily on keeping the right size matched to the wheel package. This model uses radial fitments in two sizes, 245/45R18 and 245/40R19, depending on sub-model and wheel setup. Available choices center on blackwall performance-oriented tire lines from BFGoodrich and Nitto. The key is confirming the exact sub-model and wheel diameter first, then choosing the tire that best suits your driving priorities and factory-style proportions.
Which Tire Size Is Right for The 2019 Lincoln MKZ
The 2019 Lincoln MKZ uses two primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. Both are radial metric sizes, but they are tied to different 18-inch and 19-inch wheel applications. Before choosing a tire, confirm whether the car is on its correct factory wheel package or has been changed to a different diameter, since that determines which size belongs on the vehicle.
Fit(s): Base, Hybrid, Reserve I, and Reserve I Hybrid
Construction: Radial|Rim: 18 in
A 245/45R18 tire uses a 245-millimeter nominal section width, a 45-series aspect ratio, radial construction, and an 18-inch rim. On the 2019 Lincoln MKZ, this size supports the sedan’s modern ride and handling balance while keeping the fitment tied to the correct 18-inch wheel package. Available choices include blackwall tires from BFGoodrich and Nitto across g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2 lines. This size is the one to evaluate if your MKZ uses 18-inch wheels and you are comparing tread character, load specification, or rim-width compatibility within the proper fitment.
Fit(s): Reserve I, Reserve I Hybrid, Reserve II, and Reserve II Hybrid
Construction: Radial|Rim: 19 in
A 245/40R19 tire keeps the same 245-millimeter nominal width but uses a lower 40-series profile on a 19-inch rim. For the 2019 Lincoln MKZ, this size is associated with 19-inch wheel applications, giving the buyer a different wheel-and-tire package rather than a casual substitute for the 18-inch setup. BFGoodrich offers this size in blackwall form through the g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A series. This is the size to focus on when the car is equipped with the correct 19-inch wheels and you want to compare series character and wheel-width range within that fitment.
Tire fitment for the 2019 Lincoln MKZ varies by sub-model, and some Reserve trims can use either of the two primary sizes depending on wheel package. Checking the exact trim and confirming whether the car is on 18-inch or 19-inch wheels is the first step before narrowing down tire choices.

2019 Lincoln MKZ Base
The 2019 Lincoln MKZ Base uses the 245/45R18 radial tire size. Tire selection here is mainly about choosing the right blackwall radial within the proper 18-inch fitment, while also confirming that the car has not been changed to a different wheel diameter.
The 2019 Lincoln MKZ Hybrid uses the 245/45R18 radial size as its primary fitment. That keeps the decision centered on selecting the right 18-inch radial tire series and verifying wheel compatibility if the vehicle has seen any aftermarket wheel changes.
The 2019 Lincoln MKZ Reserve I can use either 245/45R18 or 245/40R19, so the tire choice depends on the wheel package actually on the car. Confirming whether the vehicle carries 18-inch or 19-inch wheels matters more here than comparing tire brands first.
The 2019 Lincoln MKZ Reserve I Hybrid also appears with either 245/45R18 or 245/40R19 radial fitment. The practical step is to verify the installed wheel diameter, then compare the available blackwall radial options within that correct size.
The 2019 Lincoln MKZ Reserve II uses the 245/40R19 radial tire size. That places the decision on choosing among the available 19-inch blackwall performance-oriented series and making sure the wheel width stays within the tire’s intended range.
The 2019 Lincoln MKZ Reserve II Hybrid uses the 245/40R19 radial fitment. For this sub-model, the focus is on selecting the right 19-inch radial tire and confirming that the vehicle still carries the wheel setup intended for that lower-profile size.
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.
Best 2019 Lincoln MKZ Tires for Sale
Available 2019 Lincoln MKZ tire choices focus on 245/45R18 and 245/40R19 blackwall radials from BFGoodrich and Nitto. The main differences in the product grid come from tire series, load specification, and wheel-width compatibility within each of the two correct rim diameters.
Owners of a 2019 Lincoln MKZ usually need to sort out the correct tire size first, then compare 18-inch versus 19-inch fitment, available radial choices, and practical checks before regular road use. These questions focus on those exact decisions.
Tire Size & Fitment
What tire size fits a 2019 Lincoln MKZ?
The 2019 Lincoln MKZ uses two primary tire sizes: 245/45R18 and 245/40R19. Both are radial metric fitments, and the correct size depends on the sub-model and wheel package. Base and Hybrid models use 245/45R18, while Reserve II and Reserve II Hybrid use 245/40R19. Reserve I and Reserve I Hybrid can appear with either size.
The practical step is to confirm the actual wheel diameter on the car before choosing a tire. An 18-inch wheel takes 245/45R18, and a 19-inch wheel takes 245/40R19. If the MKZ has aftermarket wheels or a replacement wheel set, check the wheel markings and current tire size together so the new tires match the setup already in place.
What size rim does a 2019 Lincoln MKZ use?
A 2019 Lincoln MKZ uses either an 18-inch or 19-inch rim, depending on the tire size and sub-model configuration. The 245/45R18 fitment uses an 18-inch rim, and the 245/40R19 fitment uses a 19-inch rim. Both sizes are original-type radial applications for this model year.
Rim diameter is the first thing to verify because it determines which tire size belongs on the car. Wheel width matters too, especially if the vehicle has non-original wheels. Before selecting a tire, check the wheel’s diameter and width stamping, then compare that information with the intended tire’s recommended rim-width range to avoid choosing a size that does not suit the wheel.
Do all 2019 Lincoln MKZ sub-models use the same tire size?
No, 2019 Lincoln MKZ sub-models do not all use the same tire size. Base and Hybrid models use 245/45R18, while Reserve II and Reserve II Hybrid use 245/40R19. Reserve I and Reserve I Hybrid are the mixed-fitment trims, since they can use either 245/45R18 or 245/40R19 depending on the wheel package.
That variation means trim name alone is not always enough, especially on Reserve I and Reserve I Hybrid cars. A quick look at the current tire sidewall or the wheel diameter will usually settle the question. This matters because the two sizes fit different rim diameters, so choosing by appearance or width alone can lead to the wrong tire for the wheel on the car.
Choosing the Right Tire
What should I consider when choosing a 245/45R18 tire for a 2019 Lincoln MKZ?
A 245/45R18 tire for a 2019 Lincoln MKZ should first match the car’s 18-inch wheel setup. Within that size, the available choices include blackwall radial designs from BFGoodrich and Nitto, with series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2.
Once the size is confirmed, compare the tire’s intended character, wheel-width range, and load specification rather than focusing only on brand name. A buyer may prefer one series for all-season-oriented use and another for a more performance-focused presentation. It also helps to compare the current wheel width on the car so the selected tire suits the wheel properly.
What brands offer tires for the 2019 Lincoln MKZ?
Tires for the 2019 Lincoln MKZ are available from BFGoodrich and Nitto in the applicable sizes on this page. BFGoodrich appears in both 245/45R18 and 245/40R19, while Nitto appears in 245/45R18. All of the available choices are radial blackwall tires aimed at modern road use.
Brand is only one part of the decision. It is worth comparing which series each brand offers in your exact size, along with wheel-width compatibility and any stated load specification. That approach keeps the choice centered on the car’s actual fitment and your intended use, rather than assuming that every tire in the same size will suit the MKZ the same way.
What tire series are available for the 2019 Lincoln MKZ?
The 2019 Lincoln MKZ is covered here by several modern radial tire series, including BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2. Series availability depends on whether the car uses 245/45R18 or 245/40R19.
Comparing by series can be helpful because it shows the buyer where the real product differences are within the correct size. Some owners will be looking for a more everyday road-going tire character, while others may want a more aggressive performance-oriented option. The important thing is to narrow the search to the correct size and rim diameter first, then compare series within that fitment.
Restoration & Appearance
Does correct tire fitment matter for a 2019 Lincoln MKZ restoration or preservation project?
Yes, correct tire fitment still matters on a 2019 Lincoln MKZ, even though this is a modern luxury sedan rather than a vintage restoration case. Keeping the right 245/45R18 or 245/40R19 size on the correct wheel diameter helps preserve the car’s intended stance, wheel-to-tire proportion, and overall presentation.
For a preservation-minded owner, the goal is usually to stay close to the proper size and wheel package rather than treating tire replacement as a styling shortcut. An MKZ that has changed wheel diameters may look different and drive differently than intended. Checking trim, wheel size, and current fitment together helps maintain a more authentic appearance for the car.
How does tire construction affect the appearance of a preserved 2019 Lincoln MKZ?
On a 2019 Lincoln MKZ, tire construction is straightforward because the primary fitments are radial. That means the appearance question is less about bias-ply versus radial and more about staying with the proper modern metric size, profile, and wheel diameter so the car keeps its intended luxury-sedan look.
A lower-profile 245/40R19 presents differently than a 245/45R18 because each belongs to a different wheel package. Blackwall sidewalls are the common visual theme across the available products, so the main appearance choice comes from selecting the correct size for the sub-model and wheel. For a clean preserved look, avoid treating the two sizes as casual substitutes.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Lincoln MKZ?
Yes, modifications can affect tire fitment on a 2019 Lincoln MKZ. Wheel changes, suspension alterations, lowering, and non-original offsets can all change whether 245/45R18 or 245/40R19 remains appropriate for the car. Even when the tire size looks close, the wheel diameter and wheel width still need to match the intended fitment.
A modified MKZ should be checked as it sits, not only by original trim designation. Measuring the actual wheel diameter and width, then checking clearance at full steering lock and normal ride height, is a sensible approach. That helps prevent choosing a tire based only on the badge on the trunk when the chassis or wheel setup may no longer match factory-style dimensions.
What should I inspect before driving a 2019 Lincoln MKZ on new tires?
Before driving a 2019 Lincoln MKZ on new tires, inspect wheel condition, confirm the tire size matches the wheel diameter, and make sure inflation is set correctly for the application. It also helps to check for rubbing clearance, proper lug torque, and any signs that the car has wheel or suspension changes that could affect the new fitment.
A short test drive followed by another visual inspection is a smart next step. Listen for contact noise, watch for vibration, and look at inner fender and suspension clearance afterward. On a sedan like the MKZ, those checks are especially useful when moving between trims, replacing damaged wheels, or installing tires on a car with a wheel setup that may not be original.
How often should tires on a 2019 Lincoln MKZ be inspected?
Tires on a 2019 Lincoln MKZ should be inspected regularly, not just when tread looks low. Checking pressure, tread wear pattern, sidewall condition, and any sign of cuts, bulges, or air loss on a routine schedule helps catch problems before they affect ride quality or safety. This matters on both 245/45R18 and 245/40R19 fitments.
A monthly walkaround is a sensible baseline, with a closer inspection before longer trips or after striking road hazards. Uneven wear can point to alignment, suspension, or inflation issues rather than a tire problem alone. Since the MKZ uses two different wheel-and-tire packages across the model range, it is also worth confirming that all four tires match the intended size on the car.
