The 2017 Ford GT returned Ford’s halo supercar to the road with a carbon-fiber-intensive design, dramatic aerodynamics, and a clear focus on modern high-speed performance. Its shape, stance, and chassis setup make tire choice especially important, because the car relies on a staggered fitment rather than a single all-around size. The 2017 Ford GT uses 245/35R20 in front and 325/30R20 in the rear, both radial sizes on 20-inch rims. Available choices center on modern blackwall performance radials from BFGoodrich and Nitto in several series. The key is matching the correct front or rear size to the wheel position, then checking wheel width, condition, and clearance before road use.
Which Tire Size Is Right for The 2017 Ford GT
The 2017 Ford GT uses two tire sizes, and the difference is positional rather than trim-related: 245/35R20 at the front and 325/30R20 at the rear. Both are radial fitments on 20-inch rims, so the first step is confirming whether you are replacing a front or rear tire before comparing available product lines and specifications.
245/35R20 is a modern metric radial size: 245 is the nominal section width in millimeters, 35 is the aspect ratio, R identifies radial construction, and 20 is the rim diameter in inches. On the 2017 Ford GT, this size is used at the front, where steering response, wheel-width compatibility, and overall tire condition all matter. Available options include blackwall radial designs from BFGoodrich and Nitto across series such as g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. Choosing this size means matching the front axle fitment and verifying the wheel remains within the tire’s intended width range.
325/30R20 is also a modern metric radial size, with a much wider nominal section width and a 30-series profile built around a 20-inch wheel. On the 2017 Ford GT, this is the rear tire size, so it should be treated as a dedicated rear-axle fitment rather than an interchangeable alternative to the front size. Its role in the staggered setup makes rear wheel confirmation especially important, particularly on a car that may have seen wheel changes or other modifications. Selecting this size starts with preserving the car’s front-to-rear fitment balance and making sure the rear wheel and tire package matches the existing setup.
Sub-model fitment on the 2017 Ford GT is straightforward, but tire sizing still varies by position. The covered front and rear Base fitments use different sizes, so identifying the wheel location matters before choosing a replacement tire.

2017 Ford GT Base Front
The 2017 Ford GT Base Front uses the narrower front fitment in the car’s staggered radial setup. That makes tire selection a matter of choosing the correct front size, then comparing blackwall performance tire options that suit the wheel width and intended road use.
The 2017 Ford GT Base Rear uses the wider rear tire size, separate from the front fitment. Tire selection here should focus on preserving the rear position’s correct size and confirming that the wheel, clearance, and overall setup still match the existing staggered arrangement.
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 2017 Ford GT?
The 2017 Ford GT uses a staggered tire setup with 245/35R20 at the front and 325/30R20 at the rear. Both are radial sizes designed for 20-inch rims, so this car does not use one universal tire size at all four corners.
That means the first fitment question is whether the tire being replaced is on the front or rear axle. Matching the correct position is important on a car with this type of performance-oriented setup, and any wheel changes, suspension modifications, or prior tire substitutions should be checked before installing a replacement.
What size rim does a 2017 Ford GT use?
The 2017 Ford GT uses 20-inch rims with both of its primary tire sizes. The front 245/35R20 and rear 325/30R20 are both built around a 20-inch wheel diameter, even though the tire widths and profiles differ from front to rear.
Rim diameter is only one part of the fitment picture, so it is still worth confirming the actual wheel width and wheel position before selecting a tire. A 20-inch wheel can still vary in width, and that matters when comparing front tire options such as the available 245/35R20 radial products.
Why does the 2017 Ford GT have more than one tire size?
The 2017 Ford GT uses more than one tire size because it has a staggered fitment, with a narrower front tire and a wider rear tire. In this application, 245/35R20 is used at the front and 325/30R20 is used at the rear.
A staggered setup means front and rear tires are not chosen interchangeably, even though both use 20-inch rims. The practical step is to verify which axle needs replacement, then confirm the current wheel setup and any previous modifications so the tire size remains appropriate for the car’s existing configuration.
Choosing the Right Tire
What should I consider when choosing a 245/35R20 tire for a 2017 Ford GT?
Start with the basics: 245/35R20 is the front tire size for the 2017 Ford GT, so the tire must match that position and the 20-inch wheel diameter. From there, the main comparison points are radial tire series, stated rim-width range, load specification where shown, and overall intended use.
Available front-tire choices include BFGoodrich and Nitto blackwall radials in several performance-oriented series. The most useful approach is to compare the tire’s dimensions and wheel-width suitability against the actual front wheel on the car, especially if the GT no longer wears its original wheel and suspension setup.
What sidewall styles are available for 2017 Ford GT tires?
The available 245/35R20 tire choices for the 2017 Ford GT use a blackwall sidewall treatment. That keeps the appearance firmly modern and performance-oriented, which suits the car’s contemporary supercar character and avoids the period-style sidewall distinctions seen on vintage applications.
Since the visible sidewall style is consistent, the real differences come from tire series and specification details rather than whitewall, redline, or raised-letter appearance changes. For most owners, the more important comparison points will be front-position fitment, wheel-width compatibility, and choosing a tire series that matches how the car is driven.
What brands offer tires for the 2017 Ford GT?
The available 245/35R20 front tire options for the 2017 Ford GT come from BFGoodrich and Nitto. Within those brands, the choices include several radial performance series, giving the owner more than one path within the correct front size.
Brand alone should not decide the tire selection. It makes more sense to compare each tire’s series, intended character, published wheel-width range where stated, and any load specification that appears, then make sure the tire matches the front wheel and current setup on the car before installation.
Restoration & Appearance
Which tire should I choose for a period-style 2017 Ford GT?
A period-style approach on a 2017 Ford GT still means staying with its modern staggered radial sizing rather than trying to give it a vintage tire presentation. The core fitment remains 245/35R20 in front and 325/30R20 in the rear, both on 20-inch rims.
Because this car belongs to a modern supercar era, appearance choices come more from preserving the correct front-to-rear stance than from sidewall ornamentation. The safest visual strategy is to retain the proper axle-specific sizing and select a tire that keeps the car’s intended low-profile, blackwall look without introducing mismatched proportions.
Does correct tire fitment matter for a 2017 Ford GT restoration?
Correct tire fitment matters on a 2017 Ford GT because the car’s appearance and road manners both depend on its staggered front and rear sizing. Using the proper 245/35R20 front and 325/30R20 rear arrangement helps preserve the proportions and stance that define the car’s modern design.
Even on a newer collector vehicle, it is worth confirming the actual wheel package before replacing tires. Cars that have been displayed, stored, or modified may no longer wear the same wheels they left with, so checking wheel dimensions, clearance, and tire age is just as important as choosing the right size code.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Ford GT?
Yes. Any change to wheels, wheel width, offset, suspension height, or body clearance can affect tire fitment on a 2017 Ford GT. That matters even more on a car with a staggered setup, because the front 245/35R20 and rear 325/30R20 serve different positions and should not be treated as interchangeable.
A GT with aftermarket wheels or altered ride height deserves a careful measurement check before new tires go on. Wheel diameter, wheel width, steering clearance, and rear fender clearance should all be reviewed so the replacement tire matches the car’s current configuration rather than an assumed stock setup.
What should I inspect before driving a 2017 Ford GT on new tires?
Before road use, inspect wheel condition, tire pressure, valve stems, and the basic front and rear fitment to make sure each size is mounted in the correct position. It is also smart to look over suspension components, alignment condition, and any signs that an older tire rubbed or contacted the bodywork.
A low-use collector-performance car can hide age-related issues even when tread looks fine. Checking for air loss, sidewall damage, and signs of previous impact or storage-related deterioration helps avoid putting fresh tires onto a setup that still has unresolved wheel, alignment, or clearance problems.
How should tires on a collector 2017 Ford GT be maintained?
Tires on a collector 2017 Ford GT should be maintained with regular pressure checks, routine visual inspections, and attention to age as well as tread. Even a car driven sparingly should have its tires examined for cracking, bulges, cuts, irregular wear, and any slow loss of air.
Storage conditions matter on a high-value car that may sit for long periods. Keeping the GT away from prolonged heat, direct sunlight, moisture, and ozone sources can help protect the tires, while periodic checks of wheel condition and clearance make it easier to spot issues before the next drive.
