The 2018 Ford Taurus sits at the end of a long-running full-size Ford sedan line, blending modern comfort with a broad range of trim personalities, from everyday family transportation to the more aggressive SHO. Tire fitment matters on this car because the 2018 Ford Taurus uses three different radial sizes depending on sub-model and wheel package: 235/55R18, 255/45R19, and 245/45R20. That means the first step is confirming the exact trim and wheel diameter before choosing among available tire series and sidewall treatments. For owners focused on appearance, everyday road manners, or preserving the intended stance, matching the right size to the car’s actual wheel setup is the key decision.
Which Tire Size Is Right for The 2018 Ford Taurus
The 2018 Ford Taurus uses three primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. All three are radial metric sizes, but they do not share the same rim size, so the first step is confirming whether the car has 18-inch, 19-inch, or 20-inch wheels before comparing tire choices.
255/45R19 is a metric radial size that uses a 255-millimeter nominal section width, a 45-series profile, and a 19-inch wheel diameter. On the 2018 Ford Taurus, this size applies only to certain configurations, so it should not be assumed across the full model range. Its wider section and dedicated 19-inch fitment make it a trim-specific choice rather than a general Taurus replacement size. This is the size to evaluate when the car already wears 19-inch wheels and the goal is to keep the intended fitment rather than converting to another wheel and tire combination.
235/55R18 is a modern metric radial size with a 235-millimeter section width, a 55-series profile, and an 18-inch rim diameter. On the 2018 Ford Taurus, it is used on trims equipped with 18-inch wheels, making wheel diameter the key fitment checkpoint before replacing the tires. Its sizing format is familiar to modern drivers, but it still needs to match the actual wheel and trim package on the car. This size is the right path when maintaining an 18-inch Taurus setup and avoiding unnecessary changes to wheel diameter or overall fitment strategy.
Tire fitment on the 2018 Ford Taurus varies by sub-model, and some trims are associated with more than one wheel and tire package. Checking the exact trim matters here because the Taurus spans 18-inch, 19-inch, and 20-inch wheel diameters.

2018 Ford Taurus Limited
The 2018 Ford Taurus Limited uses either a 245/45R20 or 255/45R19 radial tire, so the actual wheel diameter on the car needs to be confirmed before ordering. That makes this trim more about verifying the existing wheel package than simply choosing among tire brands.
The 2018 Ford Taurus SE uses the 235/55R18 radial size on an 18-inch wheel. Tire selection for this trim centers on staying with the correct 18-inch fitment and then comparing product character, construction details, and intended road use.
The 2018 Ford Taurus SEL can use either 235/55R18 or 245/45R20, depending on wheel setup. This trim requires an especially careful wheel check, since tire choice depends on whether the car is equipped with 18-inch or 20-inch wheels.
The 2018 Ford Taurus SHO uses the 245/45R20 radial size. For this trim, the decision is less about identifying the size and more about choosing among the available 20-inch tire series and sidewall treatments that suit the car’s look and use.
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.

Tire Size & Fitment
What tire size fits a 2018 Ford Taurus?
A 2018 Ford Taurus can use 235/55R18, 255/45R19, or 245/45R20, depending on the sub-model and wheel package. All three are radial tire sizes, but they are tied to different rim diameters, so there is not one universal size for every Taurus trim.
The practical step is to confirm the exact trim and the actual wheel diameter on the car before replacing tires. The SE uses 235/55R18, the SHO uses 245/45R20, the Limited can use 245/45R20 or 255/45R19, and the SEL can use 235/55R18 or 245/45R20.
What size rim does a 2018 Ford Taurus use?
The 2018 Ford Taurus uses three different rim diameters depending on configuration: 18-inch, 19-inch, and 20-inch. Those wheel sizes correspond to 235/55R18, 255/45R19, and 245/45R20 tires, so the rim diameter and tire size need to match exactly.
Checking the wheel itself is important because several Taurus trims were associated with more than one tire size. A Limited or SEL owner should verify whether the car has its original wheels or an aftermarket setup, since the wrong rim diameter will immediately rule out a tire even when the vehicle year and model are correct.
Why does the 2018 Ford Taurus have more than one tire size?
The 2018 Ford Taurus has more than one tire size because different sub-models and wheel packages used different wheel diameters. The range spans 18-inch, 19-inch, and 20-inch wheels, so tire fitment changes with the trim and the wheel package rather than staying the same across the full Taurus lineup.
That matters because a Taurus owner cannot choose by year and model alone. The wheel diameter on the car must be confirmed first, especially on Limited and SEL trims that can appear with more than one fitment. Matching the existing wheel setup is the starting point before comparing tread style, sidewall look, or brand.
Choosing the Right Tire
What should I consider when choosing a 245/45R20 tire for a 2018 Ford Taurus?
Start with the actual 20-inch wheel setup and confirm that 245/45R20 is the correct fitment for the car’s trim. From there, selection comes down to comparing radial tire series, rim-width compatibility where stated, sidewall presentation, and useful specs such as load capacity or weight when those details matter to the intended use.
The available 245/45R20 assortment includes Blackwall, Redline, and RWL options, so appearance can be part of the decision as well. Buyers comparing BFGoodrich, Nitto, and Pro-Trac tires should focus on matching the car’s wheel, intended driving style, and visual preference rather than assuming every 20-inch tire serves the same purpose.
What sidewall styles are available for 2018 Ford Taurus tires?
For the available 245/45R20 fitment on the 2018 Ford Taurus, sidewall choices include Blackwall, Redline, and RWL. That gives this size a wider appearance range than a simple modern replacement tire, especially for owners who want either a subdued look or something with more visual character.
Sidewall style should be chosen after the correct size and wheel diameter are confirmed. A Blackwall keeps the look understated, while Redline and RWL add a more noticeable visual accent. Those differences do not change the need to stay with the proper 245/45R20 fitment for trims and wheel packages that use the 20-inch size.
What brands offer tires for the 2018 Ford Taurus?
Within the available 245/45R20 fitment for the 2018 Ford Taurus, brands include BFGoodrich, Nitto, and Pro-Trac. Those choices span several tire series, giving Taurus owners more than one way to approach the 20-inch radial fitment used on certain trims, including both performance-oriented and appearance-focused options.
Brand choice should come after size confirmation, especially since not every Taurus trim uses the same wheel diameter. Once 245/45R20 is confirmed, compare each tire by series, sidewall treatment, and any stated rim-width or load details that matter to the car’s setup. The goal is the right match for the vehicle’s actual wheel package and intended use.
Restoration & Appearance
Which tire should I choose for a period-style 2018 Ford Taurus?
A period-style approach on a 2018 Ford Taurus starts with keeping the correct original-size fitment for the trim and wheel diameter already on the car. Since the Taurus uses modern radial sizes, the appearance decision is less about vintage construction and more about selecting a tire that preserves the car’s intended stance and overall visual balance.
On 20-inch applications, sidewall treatment becomes part of that appearance choice because Blackwall, Redline, and RWL options are available. Owners aiming for a more stock-leaning presentation usually begin with the correct size first, then decide whether they want a subtle look or a more expressive sidewall within that same fitment.
How does tire construction affect the appearance of a restored 2018 Ford Taurus?
On a 2018 Ford Taurus, tire construction is straightforward because the primary fitments are radial. That means the visual effect comes more from the correct modern profile and wheel diameter than from choosing between bias-ply and radial construction, which is a bigger issue on older collector vehicles.
Appearance still changes noticeably when the tire size is wrong for the wheel package or when the sidewall style differs from the look you want. Keeping the proper 18-inch, 19-inch, or 20-inch fitment helps maintain the Taurus’s intended proportions, while Blackwall, Redline, or RWL options can shift the final presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Ford Taurus?
Yes. Modifications can affect tire fitment on a 2018 Ford Taurus, especially if the car has aftermarket wheels, suspension changes, or body alterations that differ from its original wheel package. Since this model already uses multiple factory wheel diameters, even a small change in setup can alter what tire size is appropriate.
A Taurus with non-stock wheels should be checked for wheel diameter, width, and clearance before new tires are chosen. Steering travel, fender clearance, and suspension movement all matter once the car has been altered. Staying with the correct trim-specific size is the safest starting point, but the actual vehicle setup always has the final say.
What should I inspect before driving a 2018 Ford Taurus on new tires?
Before driving a 2018 Ford Taurus on new tires, inspect the wheel size, confirm the tire size matches that wheel, and look over the wheels themselves for damage or irregular wear signs. It also helps to check valve stems, lug torque, inflation pressure, and basic suspension condition before the car goes back into regular road use.
A short follow-up inspection after the first miles is also worthwhile. Watch for uneven wear, rubbing, vibration, or steering pull that could point to alignment or clearance issues. On trims that could use more than one factory size, this step is especially important because the correct tire depends on the actual wheel package installed on the car.
How often should tires on a 2018 Ford Taurus be inspected?
Tires on a 2018 Ford Taurus should be inspected regularly, not only when replacement time arrives. A quick visual check for uneven wear, cuts, bulges, cracking, or air loss is a good habit, and pressure should be checked routinely because modern radial fitment depends on proper inflation for both handling and tread life.
A more careful inspection is especially useful before longer drives or after the car has been stored for a while. Since the Taurus can wear 18-inch, 19-inch, or 20-inch wheel packages, it is smart to recheck that the installed tire size matches the wheel before rotating, replacing, or troubleshooting ride and handling concerns.
