2015 Lincoln represented the brand’s modern luxury-sedan era, with the full-size MKS and midsize MKZ carrying distinct personalities but a shared focus on quiet highway comfort, upscale road manners, and contemporary wheel-and-tire packages. Unlike an earlier Lincoln year where one bias-ply size might cover the whole range, 2015 Lincoln uses four radial sizes spread across two models, with fitment changing by both model and rim diameter. That makes the real first step simple: confirm whether you have an MKS or an MKZ, then verify the wheel diameter already on the car before narrowing your choice to the correct 18-, 19-, or 20-inch size.
Which Tire Size Is Right for Your 2015 Lincoln
Four tire sizes are used across 2015 Lincoln vehicles, and they vary by model rather than being shared across the full range. Because every size here is a radial but the rim diameters differ between 18, 19, and 20 inches, the real decision starts with confirming whether your car is an MKS or MKZ and which wheels it wears. Understanding that distinction before choosing a product saves time and helps ensure the right match.
Year(s): 2015|Fit(s): MKS|Construction: Radial|Rim: 20 in
245/45R20 is a metric radial size with a 245-millimeter section width, a 45-series aspect ratio, radial construction, and fitment for a 20-inch wheel. This MKS-specific size is available from BFGoodrich and Nitto in Blackwall form, with speed ratings that vary by product, including W up to 168 mph and Y up to 186 mph. It suits an MKS owner who wants to stay with the larger-wheel fitment already on the car and should be confirmed against the actual wheel before selecting a tire.
Year(s): 2015|Fit(s): MKS|Construction: Radial|Rim: 19-in rim
255/45R19 is a metric radial size with a 255-millimeter section width, a 45-series aspect ratio, radial construction, and fitment for a 19-inch wheel. This MKS-specific size has no product range here, so the key takeaway is that it is not interchangeable with the MKS 20-inch fitment without matching the proper wheel diameter first. It is the right path for an MKS already equipped for 19-inch tires rather than the larger 20-inch package.
Year(s): 2015|Fit(s): MKZ|Construction: Radial|Rim: 19 in
245/40R19 is a metric radial size with a 245-millimeter section width, a 40-series aspect ratio, radial construction, and fitment for a 19-inch wheel. This MKZ-specific size is available from BFGoodrich in Blackwall form, with speed ratings that vary by product, including W up to 168 mph and Y up to 186 mph. It fits MKZ applications using the 19-inch wheel package and is the appropriate choice when preserving that lower-profile, late-model luxury-sport look.
Year(s): 2015|Fit(s): MKZ|Construction: Radial|Rim: 18 in
245/45R18 is a metric radial size with a 245-millimeter section width, a 45-series aspect ratio, radial construction, and fitment for an 18-inch wheel. This MKZ-specific size is available from BFGoodrich and Nitto in Blackwall form, with speed ratings that vary by product, including W up to 168 mph and Y up to 186 mph. It is the correct choice for MKZ models on 18-inch wheels and gives buyers the broadest product selection among the MKZ fitments shown here.
Two 2015 Lincoln models are covered here. Tire size does vary by model, so identifying whether you have an MKS or MKZ is essential before choosing a tire, and wheel diameter matters just as much as the size itself. Select your model below to narrow the fitment history and product options to the sedan you actually own.
2015 Lincoln MKS
The 2015 Lincoln MKS was Lincoln’s full-size sedan, aimed at buyers who wanted traditional American luxury in a modern, front-drive-based package. Its tires mount on either 19-inch or 20-inch wheels, reflecting the difference between standard and more aggressive wheel packages rather than a shared year-make size across the full Lincoln range.
The 2015 Lincoln MKZ was the brand’s midsize luxury sedan, with sleeker styling and a more contemporary sport-luxury character than the larger MKS. Its tires mount on either 18-inch or 19-inch wheels, so the wheel package on the car determines which of the two MKZ sizes applies.
Thirteen products are available across four tire sizes for 2015 Lincoln vehicles. The 245/45R20 has four radial Blackwall choices from BFGoodrich and Nitto, the 245/40R19 has three radial Blackwall choices from BFGoodrich, and the 245/45R18 has four radial Blackwall choices from BFGoodrich and Nitto. Confirm your model, wheel diameter, and the product’s speed rating before choosing.
These FAQs cover how 2015 Lincoln tire sizes split between MKS and MKZ models, what the metric radial codes mean, how sidewall and brand choices compare, and what to check for highway use, storage, and longer-drive preparation.
Size Basics & Fitment
What tire sizes fit 2015 Lincoln vehicles?
2015 Lincoln vehicles use four sizes split between two sedans. The Lincoln MKS uses 245/45R20 or 255/45R19, while the Lincoln MKZ uses 245/40R19 or 245/45R18. Rim diameters therefore vary by model and wheel package, covering 18-, 19-, and 20-inch applications rather than one universal year-make fitment.
That means year and make alone are not enough to choose a tire for a 2015 Lincoln. Start by confirming whether you have an MKS or an MKZ, then verify the wheel diameter already fitted to the car. If the wheel has been changed from stock, the mounted tire size and the actual wheel dimensions should both be checked before you settle on a replacement.
What does 245/45R20 mean on a 2015 Lincoln tire?
On a 2015 Lincoln tire, 245/45R20 means the tire is 245 millimeters wide, the sidewall height is 45 percent of that width, the R identifies radial construction, and the tire fits a 20-inch wheel. In this year-make range, that size applies to the Lincoln MKS rather than the MKZ.
The important practical point is that the final number, 20, is the wheel diameter and cannot be mixed with a 19- or 18-inch wheel. A 2015 Lincoln owner looking at 245/45R20 should confirm that the car is an MKS equipped with the 20-inch package, then compare speed rating, brand, and load specification within that exact size.
Do all 2015 Lincoln models use the same tire size?
No, 2015 Lincoln models do not use the same tire size. The MKS and MKZ each have their own two-size range, and none of the four sizes is shared across both models. Even where two sizes share a 19-inch rim diameter, they are still different sizes with different width and profile numbers.
That separation matters because an MKS owner should not assume a 19-inch MKZ tire will substitute for a 19-inch MKS tire, or vice versa. Once you confirm the model, inspect the sidewall on the tires already on the car and compare it to the wheel diameter before replacing anything. That approach prevents ordering a tire that matches the year but not the actual Lincoln model.
Buying the Right Tire
What sidewall styles are available for 2015 Lincoln tires?
2015 Lincoln tire choices here are all Blackwall radials. The 245/45R20, 245/40R19, and 245/45R18 sizes each have Blackwall options, which fits the modern luxury-sedan character of the MKS and MKZ. No whitewall or vintage sidewall treatment appears in these sizes.
For most 2015 Lincoln owners, that makes the visual decision straightforward: the main differences come from size, brand, and speed rating rather than from sidewall style. If appearance matters, compare how different tread families and shoulder shapes look on the wheel, but keep the size code and wheel diameter as the first priority because those determine whether the tire belongs on your car at all.
What brands make tires for 2015 Lincoln vehicles?
BFGoodrich and Nitto cover the available 2015 Lincoln fitments here. BFGoodrich appears in 245/45R20, 245/40R19, and 245/45R18, while Nitto appears in 245/45R20 and 245/45R18. The 255/45R19 MKS size is part of the year’s fitment picture as well, even though no product range is shown here for that size.
Brand choice matters most after you have confirmed the correct size for your MKS or MKZ. Within the same size, compare the tire series for intended use, then review speed rating and load specification so the tire suits how the car is driven. On a 2015 Lincoln, selecting the right fitment comes first and brand preference comes second.
What is the difference between BFGoodrich g-Force Sport COMP-2 and BFGoodrich g-Force Phenom T/A for the 2015 Lincoln?
For 2015 Lincoln sizes where both appear, the BFGoodrich g-Force Sport COMP-2 and g-Force Phenom T/A share the same basic fitment category but differ in speed rating and some published specifications. In 245/45R20, the Sport COMP-2 carries a 103W rating and about 30 pounds, while the Phenom T/A carries a 103Y rating, a 1,929-pound load figure at 50 psi, and about 30.73 pounds. In 245/40R19, the Sport COMP-2 is 98W at about 28 pounds, while the Phenom T/A is 98Y at about 28 pounds. In 245/45R18, the Sport COMP-2 is 96W with a 1,565-pound load figure at 51 psi, while the Phenom T/A is 100Y with a 1,764-pound load figure at 50 psi and a lower published weight.
Those distinctions matter if you are choosing between two products in the same exact size. A 2015 Lincoln owner comparing them should match the tire not only to wheel diameter and section/profile size, but also to the speed symbol and load requirement that make sense for the car’s use. When two tires share the fitment, the finer points are in the sidewall markings and published specs rather than in basic wheel compatibility.
Fitting & Setup
What rim width do 2015 Lincoln tires require?
Several 2015 Lincoln sizes have published rim-width ranges. The 245/45R20 fits 7.5- to 9.0-inch wheels, the 245/40R19 fits 8.0- to 9.5-inch wheels, and the 245/45R18 fits 7.5- to 9.0-inch wheels. Those ranges are tied to the specific tire size, not to 2015 Lincoln as a whole.
That means a wheel that works with one 2015 Lincoln size should not be assumed correct for another size without checking. If your MKS or MKZ has aftermarket wheels, measure or confirm the wheel width before choosing a tire. Staying inside the tire’s approved rim-width range helps preserve intended section shape, tread contact, and overall fit on the vehicle.
Do 2015 Lincoln tires require inner tubes?
The available 2015 Lincoln products here are modern radial tires and include tubeless markings in at least part of the range, but tube status is not presented the same way on every product. Because of that variation in marking style, the safest approach is to confirm the exact sidewall designation on the tire you choose and match it to the wheel type on the car.
Most late-model Lincoln applications use tubeless wheel-and-tire setups, but a buyer should still verify condition at the wheel itself. If the wheel has been repaired, modified, or replaced, make sure the valve stem, bead seat, and wheel construction suit the tire you plan to run. Tube decisions should be made by the specific tire and wheel combination, not by year and make alone.
Maintenance, Storage & Longevity
How should I store a 2015 Lincoln when the tires are fitted?
A stored 2015 Lincoln should be kept out of direct sunlight, away from electric motors and ozone sources, and on a dry surface with stable temperatures. Clean tires before storage, keep them properly inflated, and move the car periodically so one section of the tread does not carry the load in the same spot for months at a time. Radials generally resist flat-spotting better than older bias-ply designs, but long static storage is still hard on any collector or low-use tire.
If the car will sit for an extended season, many owners use tire cradles or place the vehicle on stands while keeping the suspension supported appropriately. The goal is to reduce stress, slow sidewall aging, and avoid permanent shape changes. When the car comes back into use, inspect every tire closely before heading onto the road.
How long do tires on a 2015 Lincoln typically last?
Tires on a 2015 Lincoln should be evaluated by age as much as by mileage. A low-use luxury sedan can have plenty of tread left while the rubber is already aging, so a five- to seven-year inspection habit is sensible, and replacement becomes a serious consideration as tires approach about ten years from their DOT date code. Heat, storage conditions, inflation habits, and driving style all influence that timeline.
For many MKS and MKZ owners, age matters more than wear bars because these cars may cover modest annual mileage. Check the four-digit DOT date code on the sidewall, then look at the overall condition of the casing and tread. If the tires are older, harder, or visibly cracking, replacement deserves attention even when tread depth still looks acceptable.
How often should tires on a 2015 Lincoln be inspected?
Tires on a 2015 Lincoln should be inspected before every drive, with a more thorough check before any longer trip. Look for cracking, cuts, punctures, bulges, uneven wear, and pressure loss, and make sure the tread is wearing evenly across the tire. Pay attention to the spare as well, since age affects it even when it never touches the road.
Regular inspection is especially important on a heavier luxury sedan because alignment changes, underinflation, or suspension wear can show up at the tires first. If one corner looks different from the others, do not assume it is just cosmetic. Catching a sidewall issue or a slow pressure leak early is far easier than discovering it after the car is already loaded for a trip.
Safety & Road Use
Are 2015 Lincoln tires safe for highway driving?
Yes, the 2015 Lincoln tire sizes covered here are modern radial designs intended for contemporary road use, and the available products carry W and Y speed ratings. W corresponds to 168 mph, while Y corresponds to 186 mph, both well beyond normal U.S. highway speeds. In everyday use, the condition of the tire, correct inflation, and the mechanical health of the car matter more than the headline speed symbol alone.
A sound MKS or MKZ on correctly matched tires can be entirely appropriate for highway touring, but any 2015 Lincoln should still be treated as a complete system. Check alignment, brakes, suspension condition, and tire age before extended high-speed travel. Even a high-rated radial is only as trustworthy as the wheel, valve stem, and chassis components supporting it.
What inflation pressure should I use for 2015 Lincoln tires?
Inflation pressure for 2015 Lincoln tires should follow the vehicle placard or owner’s manual first, because factory pressure targets are set for the specific model and wheel package. Tire pressure figures tied to the reproduction and performance products themselves describe maximum rated load conditions, not a universal everyday setting. Among the available sizes here, examples include 1,930 pounds at 50 psi for one 245/45R20 tire, 1,653 pounds at 50 psi for one 245/40R19 tire, and 1,565 to 1,764 pounds at 50 to 51 psi across 245/45R18 choices.
The practical takeaway is not to transfer one tire’s pressure figure to every 2015 Lincoln fitment. Use the car’s placard for baseline cold inflation, then confirm the chosen tire’s own sidewall information and manufacturer guidance if you are comparing different load indexes. That keeps the pressure matched to both the car and the tire rather than to a generic number.
What should I check before taking a 2015 Lincoln on a longer drive?
Before a longer drive in a 2015 Lincoln, inspect each tire for sidewall cracking, cuts, punctures, bulges, and uneven tread wear, then verify cold pressure and make sure the spare is serviceable. Confirm that all four tires match the car’s intended size for its wheel diameter, since MKS and MKZ fitments are not interchangeable across the whole year-make range. A quick look at valve stems, wheel condition, and any signs of rubbing is worthwhile too.
That tire check should be part of a broader pre-trip routine on any luxury sedan, especially one that may spend periods in low-use service. Brakes, fluids, battery condition, lights, and suspension should be reviewed alongside the tires. If anything feels off during the first miles, such as vibration, pull, or steering heaviness, stop and inspect before continuing.
