The 2018 Ford GT is a modern American supercar shaped as much by aerodynamics as by heritage, blending Ford’s endurance-racing image with an aggressively engineered road car. Its low stance, wide track, and mid-engine layout make tire selection a fitment-first decision rather than a styling exercise. This application uses staggered radial sizing, with 245/35R20 at the front and 325/30R20 at the rear, both on 20-inch rims. That means the real choice centers on using the correct front-to-rear combination and comparing available performance-oriented radial options within the proper size. Before replacing tires, it makes sense to confirm wheel specs, any modifications, and clearance at both ends of the car.
Which Tire Size Is Right for The 2018 Ford GT
The 2018 Ford GT uses two primary tire sizes, and they serve different positions on the car rather than different trim levels. Both are radial tires for 20-inch rims, with 245/35R20 used at the front and 325/30R20 used at the rear. The first step is confirming which axle you are replacing, then comparing the available tire choices in the correct size for that position.
The 245/35R20 size is a modern metric radial format: 245 indicates nominal section width in millimeters, 35 is the aspect ratio, R identifies radial construction, and 20 is the rim diameter in inches. On the 2018 Ford GT, this is the front tire size and it plays a key role in maintaining the car’s intended staggered setup. Available choices in this size include BFGoodrich and Nitto products, all with blackwall styling, across series such as g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. Choosing within this size comes down to matching the correct front fitment to the wheel and intended use.
The 325/30R20 size is also a modern metric radial, with 325 representing nominal section width in millimeters, 30 showing the aspect ratio, R denoting radial construction, and 20 identifying the wheel diameter. On the 2018 Ford GT, this is the rear tire size and it is not interchangeable with the front fitment. Its role is to preserve the GT’s wide rear stagger and overall tire balance, so axle position matters before any purchase decision. Rear tire selection should be checked against the actual wheel setup and the car’s current clearance, especially if aftermarket wheels or suspension changes are involved.
Fitment on the 2018 Ford GT is straightforward in one sense and position-specific in another. The covered front and rear applications use different sizes, so identifying whether you need the front or rear tire matters before comparing any product options.

2018 Ford GT Base Front
The 2018 Ford GT Base Front uses the 245/35R20 radial size on a 20-inch rim. For the front position, the main decision is choosing among the available blackwall radial offerings while keeping the correct staggered relationship with the rear tire.
The 2018 Ford GT Base Rear uses the 325/30R20 radial size on a 20-inch rim. Rear tire selection should stay focused on the proper wide rear fitment and on confirming wheel and clearance details if the car no longer carries its original wheel setup.
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 GT?
The 2018 Ford GT uses a staggered tire setup with two different radial sizes: 245/35R20 at the front and 325/30R20 at the rear. Both sizes are built for 20-inch rims, and they are assigned by axle position rather than by separate trim packages within this fitment set.
That means the first question is whether you need a front or rear tire, not simply whether the car is a Base model. The GT’s tire fitment depends on preserving the front-to-rear relationship, so wheel diameter, wheel width, and actual clearance should be checked carefully before mixing sizes or replacing only one end.
What size rim does a 2018 Ford GT use?
The tire fitments used on the 2018 Ford GT are both built around a 20-inch rim diameter. The front 245/35R20 and rear 325/30R20 sizes share that same rim diameter, even though the tire widths and profiles differ significantly from front to rear.
Rim diameter is only one part of the fitment picture on a staggered supercar application. It is still important to confirm the actual wheel width and overall wheel setup on the car, especially if it has aftermarket wheels, because a 20-inch diameter alone does not guarantee that every tire in the correct nominal size will suit the wheel.
Why does the 2018 Ford GT have more than one tire size?
The 2018 Ford GT uses more than one tire size because it has a staggered setup, with a narrower 245/35R20 tire at the front and a much wider 325/30R20 tire at the rear. This is a position-specific fitment, not a case of optional primary sizes for the same corner of the car.
For the owner, that means front and rear tires should be treated as separate fitment decisions. Replacing tires starts with confirming axle position, then checking that the wheel and tire combination still matches the car’s current setup, particularly if ride height, wheel offset, or other chassis details have changed since the car left stock form.
Choosing the Right Tire
What should I consider when choosing a 245/35R20 tire for a 2018 Ford GT?
Choosing a 245/35R20 tire for the 2018 Ford GT starts with confirming that you are buying for the front axle. The available options in this size are radial blackwall tires from BFGoodrich and Nitto, with differences in tire series, rim-width specifications, weight, and other product characteristics.
The best comparison points are the exact size, the wheel it will be mounted on, and how closely the product matches the car’s intended use. A front tire for this application should also be considered as part of the complete staggered setup, so it makes sense to think about how it pairs with the rear fitment rather than treating it as an isolated purchase.
What sidewall styles are available for 2018 Ford GT tires?
The currently available 245/35R20 products for the 2018 Ford GT use blackwall sidewalls. That keeps the appearance focused on a modern, understated performance look rather than on vintage-style whitewall, redline, or raised-letter treatments that belong to very different vehicle eras and tire categories.
Since sidewall style is not a major variable here, the more useful comparison points are tire series, brand, and wheel compatibility. On a car like the GT, the visual result also depends heavily on the front-to-rear stagger and the wheel design, so maintaining the proper proportions usually matters more than searching for alternate sidewall decoration.
What brands offer tires for the 2018 Ford GT?
BFGoodrich and Nitto offer available tire choices within the 245/35R20 fitment used on the front of the 2018 Ford GT. BFGoodrich appears across multiple series, including g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A, while Nitto is represented by the NT555 G2.
Brand alone should not be the only deciding factor on a staggered performance application. It helps to compare the specific tire series, the published rim-width range where available, and how the tire will be used, then confirm that the selected front tire still makes sense alongside the rear size and the car’s actual wheel setup.
Restoration & Appearance
Does correct tire fitment matter for a 2018 Ford GT restoration?
Correct tire fitment still matters on a 2018 Ford GT, even though it belongs to a modern rather than a vintage tire era. The car’s visual character depends heavily on its low profile, large wheel diameter, and pronounced front-to-rear stagger, so the right size relationship is a major part of preserving its intended appearance.
That makes size accuracy more important than searching for nostalgic sidewall details. A restoration-minded owner should confirm front-versus-rear sizing, wheel dimensions, and overall presentation before making a change, and anyone pursuing exact historical accuracy should also compare the car against marque-specific references and its individual build history.
How does tire construction affect the appearance of a restored 2018 Ford GT?
On the 2018 Ford GT, tire construction is straightforward because the primary fitments are radial. Visually, that means the car’s appearance is defined less by a bias-ply-versus-radial choice and more by maintaining the proper modern low-profile look created by the 245/35R20 front and 325/30R20 rear sizing.
For a restoration-oriented result, the key is keeping the staggered stance and matching the tire to the wheel correctly. Sidewall presentation is also simpler here because the available front products are blackwall designs, so the focus shifts to preserving proportion, clearance, and the purposeful supercar profile that belongs to this generation of GT.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Ford GT?
Yes, modifications can affect tire fitment on a 2018 Ford GT, even when the nominal tire size stays the same. Aftermarket wheels, changes in wheel offset or width, altered ride height, and suspension adjustments can all influence how a 245/35R20 front or 325/30R20 rear tire sits within the available space.
That is especially important on a low, wide car with a pronounced staggered setup. Any owner considering replacement tires should confirm wheel dimensions, steering clearance at the front, and body or suspension clearance at both ends before assuming a familiar size will behave the same way on a modified chassis.
What should I inspect before driving a 2018 Ford GT on new tires?
Before driving a 2018 Ford GT on new tires, inspect the wheel condition, verify that the front and rear tires are mounted in the correct positions, and confirm inflation is appropriate for the installed tires. It also helps to look over valve stems, check for any visible rubbing points, and make sure the tires seat properly on the wheels.
A careful first inspection matters because the GT uses different tire sizes at each end and has limited clearance compared with ordinary road cars. After a short initial drive, recheck pressure and look for any signs of contact, uneven wear, or vibration so small fitment issues can be caught before longer or faster use.
What should I check before a longer drive in a 2018 Ford GT?
Before a longer drive in a 2018 Ford GT, check tire pressure, tread condition, and the sidewalls for cuts, bulges, or cracking. Make sure the staggered 245/35R20 front and 325/30R20 rear setup remains intact, and look for any signs of air loss or uneven wear that could point to alignment or wheel issues.
Collector and low-mileage cars often spend long periods parked, so age and storage condition matter as much as tread depth. A longer trip is also a good reason to inspect for debris damage, confirm the wheels are secure, and pay attention to any change in steering feel or ride behavior once the car is back on the road.
