The 2007 Maserati GranSport sits at the end of Maserati’s coupe-and-convertible performance evolution before the brand moved fully into the next generation of GT cars. It blends Italian grand-touring character with sharper sporting intent, which makes tire fitment especially important to the way the car looks and responds on the road. This model uses radial tires, with 19-inch front and rear sizing for the Base and Spyder configurations and an 18-inch front and rear winter setup. Available choices center on modern performance-oriented blackwall radials from BFGoodrich and Nitto. The key is matching the exact front or rear size to the wheel package already on the car before comparing tire series and seasonal intent.
Which Tire Size Is Right for The 2007 Maserati GranSport
Four primary tire sizes apply to the 2007 Maserati GranSport, and the right choice depends first on whether the car has the 18-inch winter tire setup or the 19-inch Base or Spyder wheel package. This is also a staggered fitment, so front and rear sizes are different. Before selecting a tire, confirm both the sub-model and the wheel diameter currently on the car.
225/40R18 is a metric radial size in which 225 indicates the section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 18 is the wheel diameter in inches. On the 2007 Maserati GranSport, this size serves as the front fitment for the winter tire setup. Available choices are blackwall radials from BFGoodrich and Nitto across g-Force and NT555 G2 series. This size should be evaluated when the car is already equipped with the 18-inch winter front wheel package rather than the standard 19-inch arrangement.
265/35R18 is a metric radial size with a 265-millimeter nominal section width, a 35-series profile, and an 18-inch rim diameter. On the 2007 Maserati GranSport, it is the rear companion to the 18-inch winter front size, creating the correct staggered winter setup. Product options include blackwall performance radials from BFGoodrich and Nitto in several g-Force and NT555 G2 lines. This size belongs on GranSport cars using the 18-inch rear winter wheel package, so rear wheel diameter and width should be confirmed before comparing tire series.
235/35R19 is a metric radial size where 235 is the nominal section width in millimeters, 35 is the aspect ratio, and 19 is the required rim diameter. This is the front tire size used on 2007 Maserati GranSport Base and Spyder models with the 19-inch wheel setup. Available blackwall choices include Nitto NT555 G2 and BFGoodrich g-Force Phenom T/A. It is the size to focus on when maintaining the car’s standard front fitment and preserving the intended staggered relationship with the 19-inch rear tire.
265/30R19 is a metric radial size with a 265-millimeter nominal section width, a low 30-series profile, and a 19-inch wheel diameter. On the 2007 Maserati GranSport, this is the rear tire size paired with the 235/35R19 front on Base and Spyder configurations. Its low-profile, wide rear format is central to the car’s staggered performance fitment. Tire selection should start with confirming that the rear wheels are the original 19-inch setup, especially on cars that may have seen aftermarket wheel changes or seasonal wheel swaps.
Sub-model fitment on the 2007 Maserati GranSport is straightforward once the wheel package is identified. Base and Spyder models share the same 19-inch staggered setup, while the winter tire configuration uses a separate 18-inch front and rear pairing, so checking the exact sub-model and wheel diameter matters before choosing tires.

2007 Maserati GranSport (Winter Tires) Front
The winter front configuration uses the 225/40R18 radial size rather than the standard 19-inch front fitment. That makes this position-specific choice dependent on the 18-inch winter wheel setup, with selection centered on blackwall performance radial options that match the existing seasonal package.
The winter rear configuration uses 265/35R18, paired with the 18-inch winter front tire in a staggered arrangement. Tire selection here should stay focused on the rear winter wheel package and on maintaining the intended front-to-rear size relationship rather than mixing it with the 19-inch rear setup.
The Base front fitment uses 235/35R19 radial tires on the 19-inch wheel package. This keeps tire choice focused on preserving the standard front sizing while comparing the available blackwall tire series that suit the car’s existing wheels and road-use goals.
The Base rear fitment uses 265/30R19, forming the rear half of the factory-style 19-inch staggered setup. Selecting this size means confirming that the car still carries the correct 19-inch rear wheels and maintaining the proper front-and-rear pairing for appearance and fitment balance.
The Spyder front fitment matches the coupe-based Base setup with a 235/35R19 radial tire. That shared sizing simplifies tire selection, but the front wheel diameter still needs to be confirmed on any car that may have been modified or converted to a seasonal wheel package.
The Spyder rear fitment uses 265/30R19, the same rear size as the Base model on the standard 19-inch setup. Tire choice should keep that staggered arrangement intact and should be checked against the actual rear wheel size on the car before selecting a replacement.
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 2007 Maserati GranSport?
The 2007 Maserati GranSport uses a staggered radial tire setup, and the exact sizes depend on the wheel package. Base and Spyder models use 235/35R19 in front and 265/30R19 in the rear. The winter tire setup uses 225/40R18 in front and 265/35R18 in the rear.
The important step is confirming whether the car has the 19-inch standard setup or the 18-inch winter package before ordering tires. Front and rear sizes are different, so replacing only one axle still requires matching the correct position-specific size. Any car with aftermarket wheels should have both wheel diameter and tire size checked at each corner.
What size rim does a 2007 Maserati GranSport use?
A 2007 Maserati GranSport uses either 18-inch or 19-inch rims, depending on the tire setup. The winter package uses 18-inch rims with 225/40R18 front and 265/35R18 rear tires. Base and Spyder models use 19-inch rims with 235/35R19 front and 265/30R19 rear tires.
Rim diameter is the first fitment point to verify because none of these tire sizes crosses between 18-inch and 19-inch wheels. The car also uses wider rear tires than front tires, so wheel width matters along with diameter. Checking the markings on each wheel and the existing tire sidewall helps prevent mixing standard and winter-package sizes.
Do all 2007 Maserati GranSport sub-models use the same tire size?
No. The 2007 Maserati GranSport Base and GranSport Spyder share the same 19-inch staggered tire sizes, with 235/35R19 in front and 265/30R19 in the rear. The winter tire configuration uses a different 18-inch staggered setup, with 225/40R18 front and 265/35R18 rear.
That difference means sub-model name alone is not always enough; the actual wheel package on the car should be confirmed too. A GranSport may have seasonal wheels installed, or a previous owner may have changed the setup. Matching the correct front and rear sizes to the wheels already fitted is more important than assuming every GranSport uses the same combination.
Choosing the Right Tire
What should I consider when choosing a tire for a 2007 Maserati GranSport?
Start with the exact front or rear size and the wheel diameter already on the car. A 2007 Maserati GranSport uses a staggered setup, so the front and rear tires are not interchangeable, and the car may be on either the 19-inch standard arrangement or the 18-inch winter package.
Once size is confirmed, compare the available radial tire series by intended use, rim-width compatibility where stated, and any relevant load specification. Because this car relies on low-profile performance sizing, it is also worth checking the current wheel condition and making sure the replacement tire matches the position it is meant for rather than treating all four corners the same.
What brands offer tires for the 2007 Maserati GranSport?
Tires for the 2007 Maserati GranSport are available from BFGoodrich and Nitto across the applicable 18-inch and 19-inch sizes. Depending on size, the available series include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Nitto NT555 G2.
Brand choice should come after the correct size and wheel package are verified. Some sizes have more series choices than others, especially in the 18-inch winter setup, while the 19-inch front fitment has a narrower selection. Comparing brand options by tire series and fitment specifications is more useful here than choosing by brand name alone.
What sidewall styles are available for 2007 Maserati GranSport tires?
The available tires for the 2007 Maserati GranSport use a blackwall sidewall style. That applies across the BFGoodrich and Nitto products offered in the relevant 18-inch and 19-inch sizes, which keeps the appearance modern and understated rather than introducing whitewalls, raised white letters, or stripe treatments.
That consistency simplifies the visual decision, so selection comes down more to size, wheel package, and tire series than to sidewall appearance. For an owner focused on maintaining the GranSport’s contemporary sport-GT look, blackwall is the natural direction. The remaining comparison points are the exact front or rear fitment and the performance-oriented product line offered in that size.
Restoration & Appearance
Which tire should I choose for a period-style 2007 Maserati GranSport?
A period-style approach on a 2007 Maserati GranSport usually means staying with the correct staggered radial size for the wheel package already on the car. That means 235/35R19 front and 265/30R19 rear for Base and Spyder models, or 225/40R18 front and 265/35R18 rear for the winter setup.
Because this is a modern performance-era Maserati, appearance is shaped more by proper sizing and sidewall profile than by vintage-style sidewall treatments. Keeping the correct wheel diameter and front-to-rear proportion preserves the car’s intended stance. On a collector-grade car, comparing the current setup against original owner documentation or marque references is still worthwhile before changing wheel and tire specifications.
Does correct tire fitment matter for a 2007 Maserati GranSport restoration?
Yes. Correct tire fitment has a major effect on the appearance and stance of a 2007 Maserati GranSport because the car uses low-profile staggered sizes tailored to specific 18-inch or 19-inch wheel packages. Using the wrong front or rear size can alter the visual balance and create avoidable fitment complications.
Restoration-minded owners should look beyond brand alone and make sure the tire size matches the wheel diameter and axle position exactly. This matters even more on cars that have changed hands several times, since wheel swaps are common. Preserving the intended front-and-rear relationship is one of the simplest ways to keep the car looking right without making unsupported originality assumptions.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2007 Maserati GranSport?
Yes. Modifications can affect tire fitment on a 2007 Maserati GranSport, especially because the car uses low-profile staggered sizes on either 18-inch or 19-inch wheels. Aftermarket wheels, different offsets, suspension changes, or ride-height adjustments can all change how much room is available at the fender, inner wheelhouse, and steering components.
A GranSport that no longer has its original wheel setup should have each wheel diameter and width checked before new tires are selected. Clearance at full steering lock and under suspension compression is just as important as the number printed on the sidewall. That extra verification matters most when replacing one axle at a time or returning a modified car to stock-style sizing.
What should I inspect before driving a 2007 Maserati GranSport on new tires?
Before driving a 2007 Maserati GranSport on new tires, inspect the wheels for damage, verify that the front and rear sizes match the correct positions, and make sure inflation is set appropriately for the installed tires and vehicle use. It is also smart to confirm that valve stems, balancing, and mounting condition are all in order.
A quick follow-up check after the first miles is worthwhile on a low-profile staggered setup like this one. Look for any signs of rubbing, uneven seating, vibration, or air loss, and pay attention to steering feel if the car has not been driven recently. On a collector or seasonal vehicle, fresh tires should also prompt a broader inspection of alignment and suspension condition.
How should tires on a collector 2007 Maserati GranSport be maintained?
Tires on a collector 2007 Maserati GranSport should be inspected regularly even if the car is driven infrequently. Check for pressure loss, sidewall cracking, tread damage, bulges, and uneven wear, and keep the car stored away from prolonged sunlight, moisture, and ozone sources when possible.
Low annual mileage does not stop tires from aging, so time and condition matter as much as tread depth on a collectible GranSport. It also helps to verify that the car still wears the proper front and rear sizes for its wheel package, since seasonal or previous-owner changes can complicate replacement. Any sign of age-related deterioration deserves attention before extended road use.
