The 2018 Ford Trucks Edge sits in the modern crossover segment where daily usability, highway comfort, and trim-dependent wheel packages all play a big role in tire choice. On this model, tire selection is less about vintage-style construction and more about matching the correct radial size to the exact trim and wheel diameter. The 2018 Ford Trucks Edge uses four primary sizes: 245/60R18, 245/55R19, 245/50R20, and 265/40R21. That means the key decision is confirming whether the vehicle is an SE, SEL, Sport, or Titanium setup before comparing replacement tires. Wheel size comes first, then profile, appearance, and intended road use.
Which Tire Size Is Right for The 2018 Ford Trucks Edge
The 2018 Ford Trucks Edge uses four primary tire sizes, and the correct one depends on the exact sub-model and wheel package. All of them are radial sizes, but they span 18-inch, 19-inch, 20-inch, and 21-inch rims, so confirming the trim and actual wheel diameter is the first step before choosing a replacement tire.
245/60R18 is a metric radial size where 245 identifies the nominal section width in millimeters, 60 is the aspect ratio, R indicates radial construction, and 18 is the rim diameter in inches. On the 2018 Ford Trucks Edge, this size is used on 18-inch wheel applications and represents a mainstream modern crossover fitment. Its proportions balance sidewall height and wheel diameter in a way that suits everyday driving and replacement shopping. This is the size to focus on when the vehicle is equipped with the covered 18-inch setup rather than the larger wheel packages.
245/50R20 follows the same modern metric radial format, with a 245-millimeter nominal width, a 50-series profile, radial construction, and a 20-inch rim diameter. On the 2018 Ford Trucks Edge, this size belongs to specific higher-trim wheel applications rather than the full model range. The lower aspect ratio gives it a different visual and fitment character than the 18-inch and 19-inch sizes, even though the width stays similar. This size should be evaluated only after confirming that the Edge is one of the sub-models equipped with the 20-inch wheel setup.
265/40R21 is a metric radial size with a wider 265-millimeter nominal section width, a 40-series profile, radial construction, and a 21-inch rim diameter. On the 2018 Ford Trucks Edge, it is tied to a specific large-wheel application rather than broad use across the lineup. Compared with the other sizes used on this model, it stands out for both width and wheel diameter, which makes wheel confirmation especially important. This is the size to review when the vehicle has the 21-inch setup and the owner wants to stay with the proper original wheel package dimensions.
245/55R19 is a modern metric radial size that uses a 245-millimeter nominal width, a 55-series profile, radial construction, and a 19-inch rim diameter. On the 2018 Ford Trucks Edge, this size applies to a specific trim-level wheel package and sits between the 18-inch and 20-inch options in overall layout. It keeps the same nominal width as several other Edge fitments while pairing it with a different sidewall proportion and wheel diameter. This size makes sense only after verifying that the vehicle is equipped with the covered 19-inch wheel configuration.
Sub-model fitment matters on the 2018 Ford Trucks Edge because tire size changes with trim and wheel package. Some versions share one straightforward size, while Sport and Titanium can use more than one, so identifying the exact configuration comes before selecting replacement tires.

2018 Ford Trucks Edge SE (AWD)
The 2018 Ford Trucks Edge SE (AWD) uses the 245/60R18 radial size. Tire selection is mainly about staying with the correct 18-inch fitment and comparing replacement options that suit the vehicle's wheel setup and intended driving use.
The 2018 Ford Trucks Edge SE (FWD) also uses the 245/60R18 radial size. That keeps replacement shopping simple, but the wheel diameter still needs to match before moving on to tread style, road manners, and general replacement priorities.
The 2018 Ford Trucks Edge SEL uses the 245/60R18 radial size as well. For this sub-model, the main task is confirming the 18-inch wheel setup and then choosing a tire that matches the vehicle's everyday use and overall ride expectations.
The 2018 Ford Trucks Edge Sport can use either 245/50R20 or 265/40R21 radial tires, depending on the wheel package. That makes wheel-diameter verification essential before replacement, since the two sizes are tied to different rims and should not be treated as the same fitment.
The 2018 Ford Trucks Edge Titanium can use either 245/50R20 or 245/55R19 radial tires. Tire selection starts with confirming whether the vehicle has the 19-inch or 20-inch wheel package, since the two sizes serve different wheel diameters and profiles.
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.
Frequently Asked Questions
Common questions for the 2018 Ford Trucks Edge usually center on trim-specific tire size, wheel diameter, choosing among the four radial fitments, and checking clearance or wheel setup before replacement.
Tire Size & Fitment
What tire size fits a 2018 Ford Trucks Edge?
The 2018 Ford Trucks Edge uses four primary tire sizes: 245/60R18, 245/55R19, 245/50R20, and 265/40R21. The correct size depends on the exact sub-model and wheel package, not just the model name alone. SE AWD, SE FWD, and SEL use 245/60R18, while Sport and Titanium can use larger wheel fitments.
The most important step is checking the actual wheel diameter on the vehicle before buying tires. A Sport can use either 20-inch or 21-inch fitment, and a Titanium can use either 19-inch or 20-inch fitment, so trim badge alone is not always enough if wheels have been changed.
What size rim does a 2018 Ford Trucks Edge use?
A 2018 Ford Trucks Edge can use 18-inch, 19-inch, 20-inch, or 21-inch rims, depending on sub-model and wheel package. The 245/60R18 size uses an 18-inch rim, 245/55R19 uses a 19-inch rim, 245/50R20 uses a 20-inch rim, and 265/40R21 uses a 21-inch rim.
Rim diameter needs to match the tire size exactly, so this is the first thing to confirm when replacing tires. Looking only at tread width can be misleading, since several Edge sizes share a similar width but require different wheel diameters and different sidewall proportions.
Do all 2018 Ford Trucks Edge sub-models use the same tire size?
No. The 2018 Ford Trucks Edge uses different tire sizes across its sub-models. SE AWD, SE FWD, and SEL use 245/60R18, while Sport uses either 245/50R20 or 265/40R21, and Titanium uses either 245/55R19 or 245/50R20.
That variation means replacement shopping should start with the exact trim and actual wheel setup on the vehicle. It is especially important on Sport and Titanium models, where more than one factory wheel diameter applies, and previous wheel changes can make a quick visual check worthwhile before ordering.
Choosing the Right Tire
What should I consider when choosing a 2018 Ford Trucks Edge tire?
Start with the correct tire size for the exact 2018 Ford Trucks Edge sub-model and wheel diameter. This model uses four different radial fitments, so size confirmation comes before any other comparison. Once that is settled, the next considerations are the vehicle's use, preferred ride feel, and the importance of staying with the current wheel package.
A practical comparison should include rim diameter, width category, and sidewall profile rather than looking at one measurement in isolation. It also helps to inspect whether the Edge still has its original wheel setup, because aftermarket wheels or previous tire substitutions can change what belongs on the vehicle now.
How do I choose between the available 2018 Ford Trucks Edge tire sizes?
The available tire sizes are not interchangeable choices across the whole 2018 Ford Trucks Edge range. Each size belongs to a particular sub-model or wheel package, so the correct decision is based on the wheel diameter already on the vehicle. A 245/60R18 setup serves a different application than a 245/50R20, 245/55R19, or 265/40R21 setup.
The simplest approach is to confirm the trim, read the size on the current tire, and verify the wheel diameter directly. That matters most on Sport and Titanium models, where more than one wheel package exists and selecting by model name alone can lead to the wrong replacement size.
Which tire size should I use for my 2018 Ford Trucks Edge sub-model?
The right size depends on the sub-model. SE AWD, SE FWD, and SEL use 245/60R18. Sport uses either 245/50R20 or 265/40R21, while Titanium uses either 245/55R19 or 245/50R20. Every one of these is a radial fitment, but the wheel diameters and sidewall profiles differ.
Checking the sub-model is helpful, but confirming the actual wheel package is even more important when two sizes are possible within the same trim. Reading the current sidewall and measuring wheel diameter gives the clearest path, especially if the Edge has seen wheel upgrades or replacement wheels over time.
Restoration & Appearance
Does correct tire fitment matter for a 2018 Ford Trucks Edge restoration?
Yes. Even on a newer vehicle like the 2018 Ford Trucks Edge, correct tire fitment still matters if the goal is to keep the vehicle close to its proper trim-level presentation. The Edge uses multiple wheel-and-tire combinations, and each one affects the vehicle's stance, sidewall profile, and overall visual balance.
A restoration-minded owner should begin by confirming the exact sub-model and wheel diameter that belong on the vehicle now. That keeps the appearance consistent with the intended setup and helps avoid mixing sizes that may look out of place even if they appear close at a glance.
How does tire size affect the appearance of a 2018 Ford Trucks Edge?
Tire size changes the look of a 2018 Ford Trucks Edge because each fitment pairs a different wheel diameter with a different sidewall profile. An 18-inch 245/60R18 setup presents more sidewall, while the 20-inch and 21-inch sizes create a larger-wheel, lower-profile appearance tied to specific trim packages.
That visual difference is one reason wheel confirmation matters before replacement. Owners who want to preserve the intended look of an SE, SEL, Sport, or Titanium should stay focused on the size matched to that wheel package rather than choosing by width alone or by what happens to be already installed.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Ford Trucks Edge?
Yes. Modifications can affect tire fitment on a 2018 Ford Trucks Edge even when the tire size seems close to one of the standard options. Aftermarket wheels, changes in wheel offset, suspension lowering, or body alterations can all influence how a tire sits within the wheel opening and how much clearance remains.
That is why the current setup should be checked rather than assuming the vehicle still matches its original trim package. A changed wheel diameter or offset can alter the correct replacement path, and clearance at the fender, suspension, and steering range should be verified before mounting new tires.
What should I inspect before driving a 2018 Ford Trucks Edge on new tires?
Before driving a 2018 Ford Trucks Edge on new tires, inspect the wheel size, confirm the installed tire size matches the wheel diameter, and check that tire pressures are set properly. It is also smart to look over the suspension and steering components so the new tires are not being asked to work around worn hardware.
A short inspection drive should include listening for rubbing, checking straight-line behavior, and making sure the tires clear through normal steering movement. Rechecking pressure after the first miles is a good habit, and any vibration or contact issue should be addressed before putting the vehicle into regular service.
How often should tires on a 2018 Ford Trucks Edge be inspected?
Tires on a 2018 Ford Trucks Edge should be inspected regularly, not just when replacement time arrives. Frequent checks for uneven wear, cuts, bulges, embedded debris, and visible air loss help catch problems early. On a vehicle with multiple possible wheel packages, routine inspection also helps confirm that the current tire setup still matches the intended application.
A monthly pressure and condition check is a sensible routine, with an extra inspection before longer trips. It also helps to look closely after pothole impacts or curb contact, since low-profile 20-inch and 21-inch fitments can deserve especially careful wheel and sidewall inspection afterward.
