The 2006 Ford GT was built as a modern supercar with unmistakable links to Ford's mid-engine endurance-racing heritage, so tire fitment is a core part of preserving the car's stance, balance, and intended road manners. Unlike many vintage applications that revolve around one all-around size, the 2006 Ford GT uses a staggered radial setup with 235/45R18 in front and 315/40R19 in the rear. That makes wheel position just as important as size selection. Available choices in the front size center on blackwall BFGoodrich radial performance tires across several g-Force series. Before choosing replacements, confirm front-versus-rear fitment, wheel dimensions, and whether the car still retains its original wheel setup.
Which Tire Size Is Right for The 2006 Ford GT
The 2006 Ford GT uses two primary tire sizes, and they are position-specific rather than interchangeable. The front tire is 235/45R18 on an 18-inch rim, while the rear tire is 315/40R19 on a 19-inch rim, so the first step is confirming which axle you are replacing and verifying wheel diameter before comparing tire options.
In 235/45R18, the 235 identifies nominal section width in millimeters, 45 is the aspect ratio, R denotes radial construction, and 18 is the rim diameter in inches. On the 2006 Ford GT, this is the front tire size, making it part of the car's staggered setup rather than a universal fitment for every wheel position. Available choices in this size include BFGoodrich blackwall radials in several g-Force series. That makes the decision less about basic size fitment and more about selecting the right performance-oriented tire within the correct front-wheel dimensions.
In 315/40R19, the 315 identifies nominal section width in millimeters, 40 is the aspect ratio, R indicates radial construction, and 19 is the rim diameter in inches. On the 2006 Ford GT, this is the rear tire size, so it works as the wider back-half fitment in the factory-style staggered arrangement. Its role is distinct from the front tire and should not be evaluated as a substitute for the 18-inch front application. Choosing this size starts with confirming the rear wheel position and making sure the wheel diameter and overall setup have not been changed from stock.
Fitment on the 2006 Ford GT is straightforward once wheel position is identified, because the covered front and rear applications use different tire sizes. Checking the exact sub-model matters here mainly to separate the front 18-inch fitment from the rear 19-inch fitment before selecting a tire.

2006 Ford GT Base Front
The 2006 Ford GT Base Front uses a 235/45R18 radial tire, which serves as the front half of the car's staggered setup. Tire selection at this position centers on choosing the correct 18-inch front fitment and comparing available blackwall radial options within that size.
The 2006 Ford GT Base Rear uses a 315/40R19 radial tire, giving the rear axle its own distinct wheel and tire specification. That means replacement decisions should focus on the correct 19-inch rear fitment and on confirming that wheel dimensions and rear clearance remain consistent with the car's current 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 2006 Ford GT?
The 2006 Ford GT uses a staggered radial tire setup with 235/45R18 in front and 315/40R19 in the rear. Those are two different primary sizes, and each one belongs to a specific wheel position rather than serving as an all-around fitment for the car.
Selecting the right tire starts with confirming whether the replacement is for the front or rear axle. Because the Ford GT also uses different rim diameters front and rear, any replacement should be checked against the actual wheel on the car, especially if aftermarket wheels or previous tire changes may have altered the setup.
What size rim does a 2006 Ford GT use?
The 2006 Ford GT uses an 18-inch front rim with the 235/45R18 tire and a 19-inch rear rim with the 315/40R19 tire. The staggered wheel diameters are part of the car's original fitment pattern and are tied directly to the two different tire sizes.
That makes rim-diameter confirmation one of the first checks before ordering replacement tires. A front tire must match the 18-inch front wheel, and a rear tire must match the 19-inch rear wheel, so wheel position and actual wheel size should both be verified before comparing tire series or other product differences.
Why does the 2006 Ford GT have more than one tire size?
The 2006 Ford GT has more than one tire size because it uses a staggered setup, with a narrower 235/45R18 tire in front and a much wider 315/40R19 tire in the rear. That arrangement is part of the vehicle's design rather than a sign of conflicting fitments.
For the owner, the practical takeaway is simple: front and rear tires should be treated as separate fitment decisions. Tire replacement begins by identifying the wheel position, then confirming the wheel diameter and current wheel setup so the new tire matches the axle it is meant to serve.
Choosing the Right Tire
What should I consider when choosing a 235/45R18 tire for a 2006 Ford GT?
Start with the basics: the 2006 Ford GT front application uses 235/45R18 radial tires on an 18-inch rim. In this size, available choices include BFGoodrich blackwall tires across several g-Force series, with rim-width specifications around the 7.5- to 9-inch range and some variation in weight and load details.
The best comparison points are the tire series, the intended road use, and how closely the wheel matches the tire's approved rim-width range. It also helps to verify whether the car still has its original-style wheel package, since wheel changes can affect how a given front tire sits and performs.
What sidewall styles are available for 2006 Ford GT tires?
The available 235/45R18 products for the 2006 Ford GT front fitment use a blackwall sidewall style. That keeps the presentation modern and performance-oriented, which suits the GT's contemporary supercar character rather than a vintage whitewall or period muscle-car sidewall treatment.
Sidewall appearance still matters because it influences how the tire looks against the wheel and bodywork. Once the correct front size is confirmed, the remaining decision is less about decorative sidewall variety and more about choosing the right tire series and specifications for the way the car will be driven and presented.
What brands offer tires for the 2006 Ford GT?
For the 235/45R18 front size used on the 2006 Ford GT, the available products come from BFGoodrich. Those offerings span multiple g-Force series, so brand choice is not the main dividing line here in the way it might be on an older car with broader cross-brand variety.
That means tire selection comes down to comparing the differences within the BFGoodrich lineup rather than choosing between competing manufacturers in the same displayed fitment. Looking at tire series, rim-width compatibility, stated load details where present, and the car's intended use will be more useful than focusing on brand alone.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 Ford GT?
Yes. Modifications can affect tire fitment on a 2006 Ford GT, especially if the car has aftermarket wheels, suspension changes, altered ride height, or bodywork changes around the wheel openings. Even when the nominal tire size stays the same, wheel width and related geometry can change how the tire sits on the car.
Any GT with non-stock wheels or chassis changes deserves a closer look before replacement tires are chosen. Confirm the actual front and rear wheel diameters first, then check wheel width, steering clearance up front, and body or suspension clearance at the rear so the new tires suit the car's current configuration.
What should I inspect before driving a 2006 Ford GT on new tires?
Before driving a 2006 Ford GT on new tires, inspect the wheels for damage, confirm that the front and rear tire sizes are mounted in the correct positions, and make sure inflation is set appropriately for the tires being used. It also helps to look for valve-stem condition, bead sealing, and any signs of rubbing or uneven previous wear.
A short, careful road test is worthwhile after installation. Pay attention to steering feel, vibration, and any clearance issues at low speed first, then recheck air pressure after the tires have settled. On a car like the GT, even small setup issues are easier to address early than after extended driving.
What should I check before a longer drive in a 2006 Ford GT?
Before a longer drive in a 2006 Ford GT, check tread condition, air pressure, wheel fastener torque, and the general condition of the tires for cuts, bulges, cracking, or air loss. On a low-use performance car, tire age and storage history matter just as much as tread depth.
A longer trip also calls for confirming that the staggered setup is still correct, with the 18-inch front and 19-inch rear fitments in their proper positions. Looking over the suspension, alignment behavior, and any signs of contact inside the wheel wells can help prevent a small issue from becoming a roadside problem.
