The 2010 Maserati GranTurismo blends Italian grand touring character with a wide, low stance that makes tire fitment a central part of both its look and its road manners. By this point in the model’s run, the GranTurismo was established as a modern performance coupe and convertible rather than a vintage restoration case, so the tire decision is less about preserving bias-ply character and more about matching the correct staggered radial setup to the car’s configuration. This GranTurismo uses radial tires in either 20-inch or 19-inch fitments depending on sub-model. Available choices range from blackwall performance tires to raised white letter and redline options on selected rear sizes, making wheel diameter and exact front-to-rear setup the first thing to confirm.
Which Tire Size Is Right for The 2010 Maserati GranTurismo
The 2010 Maserati GranTurismo uses four primary tire sizes, and the right combination depends on both sub-model and wheel diameter. Some versions use a staggered 20-inch setup with 245/35R20 front and 285/35R20 rear, while certain coupe fitments also appear with 19-inch wheels using 245/40R19 front and 285/40R19 rear. Before choosing a tire, confirm whether the car has 19-inch or 20-inch wheels and then match the correct front and rear sizes.
Fit(s): Convertible Front, Coupe Front, and S Front
Construction: Radial|Rim: 20 in
245/35R20 is a metric radial size where 245 is the section width in millimeters, 35 is the aspect ratio, R identifies radial construction, and 20 is the wheel diameter in inches. On the 2010 Maserati GranTurismo, this size serves as a front fitment on 20-inch wheel applications, giving it a low-profile, modern performance-oriented role. Available choices include BFGoodrich and Nitto blackwall tires across series such as g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. This is the size to evaluate when the car uses the 20-inch front setup and the goal is balancing correct fitment with the preferred tire series and driving style.
285/35R20 is a wider metric radial size, with 285 denoting section width in millimeters, 35 indicating the sidewall profile, and 20 identifying the rim diameter. On the 2010 Maserati GranTurismo, it functions as the rear tire in the 20-inch staggered arrangement, pairing with 245/35R20 up front rather than serving as a universal single-size fitment. Product choices include blackwall options from BFGoodrich and Nitto, along with Pro-Trac Street Pro III versions in raised white letter and redline sidewall treatments. This rear size matters when appearance and rear-tire presentation are part of the decision, especially on cars already equipped with 20-inch wheels.
245/40R19 is a metric radial size that uses a 245-millimeter section width, a 40-series aspect ratio, and a 19-inch wheel diameter. On the 2010 Maserati GranTurismo, this size appears as a front fitment for 19-inch coupe applications, making it part of a different wheel package than the 20-inch setup used elsewhere in the range. Available selections are blackwall BFGoodrich tires in g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A series. This is the front size to verify when the coupe is running 19-inch wheels and the goal is staying with the correct rim diameter and front-to-rear stagger.
285/40R19 is a metric radial rear size, with a 285-millimeter section width, 40-series profile, and 19-inch rim diameter. On the 2010 Maserati GranTurismo, it is the rear companion to 245/40R19 on 19-inch coupe setups, so it should be treated as part of a matched staggered arrangement rather than mixed with the 20-inch front and rear sizes. This size defines the rear fitment for cars equipped with the 19-inch wheel package and helps maintain the intended relationship between front and rear tire dimensions. The key step is confirming that the car actually has the 19-inch rear wheel before selecting a replacement.
Sub-model fitment on the 2010 Maserati GranTurismo is driven mainly by front-versus-rear position and by whether the car uses 19-inch or 20-inch wheels. Checking the exact sub-model matters because the convertible and S use the 20-inch staggered setup, while the coupe can appear with either 19-inch or 20-inch front and rear sizes.

2010 Maserati GranTurismo Convertible Front
The 2010 Maserati GranTurismo Convertible Front uses the 245/35R20 radial front size as part of the 20-inch staggered setup. Tire selection here centers on choosing the right 20-inch front tire series and confirming that the car still retains the intended wheel diameter.
The 2010 Maserati GranTurismo Convertible Rear uses the 285/35R20 radial rear size, paired with the 20-inch front fitment rather than with the 19-inch coupe setup. That makes rear-sidewall style and series choice more relevant only after the 20-inch wheel package has been confirmed.
The 2010 Maserati GranTurismo Coupe Front can use either a 245/35R20 radial or a 245/40R19 radial, depending on which wheel package is on the car. Front tire selection starts with confirming whether the coupe has 20-inch or 19-inch wheels, then matching the correct staggered front size to that setup.
The 2010 Maserati GranTurismo Coupe Rear can use either 285/35R20 or 285/40R19, again depending on the wheel diameter fitted to the car. Rear tire choice should follow wheel confirmation first, then consideration of sidewall style and tire series where the selected rear size offers more than one presentation.
The 2010 Maserati GranTurismo S Front uses the 245/35R20 radial size on a 20-inch wheel. Once that front fitment is confirmed, the decision becomes choosing among available blackwall performance-oriented tire series in the correct size.
The 2010 Maserati GranTurismo S Rear uses the 285/35R20 radial rear size as part of the 20-inch staggered arrangement. Buyers choosing for this position can compare blackwall, raised white letter, and redline presentations where appearance matters alongside the correct rear sizing.

Tire Size & Fitment
What tire size fits a 2010 Maserati GranTurismo?
The 2010 Maserati GranTurismo uses a staggered radial setup, but the exact sizes depend on the configuration. The 20-inch arrangement uses 245/35R20 in front and 285/35R20 in the rear. Certain coupe applications also use a 19-inch arrangement with 245/40R19 in front and 285/40R19 in the rear.
The key is matching the correct front and rear pair to the wheels actually on the car. A GranTurismo with 20-inch wheels should stay with the 20-inch front and rear sizes, while a 19-inch coupe setup should use the 19-inch pair. Checking only one axle or ordering by model name alone can lead to a mismatch.
What size rim does a 2010 Maserati GranTurismo use?
A 2010 Maserati GranTurismo uses either 20-inch or 19-inch rims, depending on the sub-model and wheel package. The 20-inch fitments are paired with 245/35R20 front and 285/35R20 rear tires, while the 19-inch fitments are paired with 245/40R19 front and 285/40R19 rear tires.
Wheel diameter should be confirmed before choosing tires because the GranTurismo does not use one universal rim size across all covered configurations. It is also worth checking wheel width when comparing products, since some tires include stated rim-width ranges. That is especially important if the car has aftermarket wheels rather than the original wheel setup.
Why does the 2010 Maserati GranTurismo have more than one tire size?
The 2010 Maserati GranTurismo has more than one tire size because it uses staggered front and rear fitments, and because the coupe can appear with either 19-inch or 20-inch wheels. Front tires are narrower than rear tires, and the wheel diameter determines whether the car uses the 35-series 20-inch pair or the 40-series 19-inch pair.
That means the first decision is not simply choosing a brand. The car’s exact sub-model and wheel diameter need to be confirmed first, then the correct front and rear sizes can be matched to that setup. Treating the GranTurismo as a single-size application can create problems with mounting, stance, and front-to-rear balance.
Choosing the Right Tire
What should I consider when choosing a tire for a 2010 Maserati GranTurismo?
Start with the correct front and rear size pairing for the car’s wheel diameter. A 2010 Maserati GranTurismo may use 245/35R20 and 285/35R20 on 20-inch wheels, or 245/40R19 and 285/40R19 on 19-inch wheels. Once the fitment is confirmed, compare tire series, construction details, and any stated rim-width specifications.
From there, the decision becomes more about how the car is used and how the owner wants it to look. Some sizes are available only as blackwall tires, while 285/35R20 also adds raised white letter and redline choices. Matching the right size first keeps the comparison focused on meaningful differences instead of correcting avoidable fitment mistakes.
What sidewall styles are available for 2010 Maserati GranTurismo tires?
Sidewall style depends on the tire size. Blackwall options are available across the front sizes and in the 19-inch applications, while the 285/35R20 rear size also includes raised white letter and redline choices. Those appearance differences are tied to the specific rear 20-inch fitment rather than the whole GranTurismo range.
That makes sidewall selection a secondary decision after wheel diameter and axle position are confirmed. Owners keeping a restrained modern look may prefer blackwall tires, while those wanting a more customized presentation may look at raised white letter or redline on the rear. The important step is choosing a style within the correct size, not using sidewall preference to drive fitment.
What brands offer tires for the 2010 Maserati GranTurismo?
Available brands for the 2010 Maserati GranTurismo include BFGoodrich, Nitto, and Pro-Trac, depending on size. BFGoodrich appears across several front and rear fitments in g-Force series, Nitto offers NT555 G2 options in selected 20-inch sizes, and Pro-Trac appears in the 285/35R20 rear size with multiple sidewall presentations.
Brand should be compared alongside size, wheel diameter, and product character rather than treated as the only decision. Some brands are present only in certain fitments, and some appearance options exist only in one rear size. It helps to narrow the search by the car’s actual wheel setup first, then compare the available brand and series choices within that fitment.
Restoration & Appearance
Which tire should I choose for a period-style 2010 Maserati GranTurismo?
A period-style approach on a 2010 Maserati GranTurismo still starts with the correct modern radial size for the car’s wheel setup. Since this is a contemporary grand touring car rather than a bias-ply-era restoration, the visual decision is usually about keeping the proper staggered stance and selecting a sidewall treatment that suits the car’s presentation.
Most fitments are blackwall, which maintains the clean, understated look many owners want on a modern Maserati. On cars using 285/35R20 at the rear, raised white letter and redline options create a more customized appearance. When exact showroom-era appearance matters, wheel style and overall presentation should be checked just as carefully as tire size.
How does tire construction affect the appearance of a restored 2010 Maserati GranTurismo?
On the 2010 Maserati GranTurismo, construction is straightforward because the primary fitments are radial tires throughout. The visual differences come less from bias-ply-versus-radial considerations and more from profile, wheel diameter, and sidewall style. A 19-inch setup and a 20-inch setup can change the car’s stance noticeably even when both are correct applications.
For an appearance-focused project, the main concern is keeping the intended front-to-rear stagger and matching the tire profile to the wheel package already on the car. Sidewall treatment also matters, especially where blackwall, raised white letter, and redline options exist. A clean, cohesive look usually comes from consistency across all four positions rather than from one standout tire choice.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2010 Maserati GranTurismo?
Yes, modifications can affect tire fitment on a 2010 Maserati GranTurismo even when the tire size itself is correct. Aftermarket wheels, changes in wheel width, altered offset, suspension lowering, and body or fender changes can all influence clearance at the front or rear. That is especially important on a low-profile staggered setup.
A GranTurismo that no longer has its original wheel and suspension configuration should be checked carefully before new tires are chosen. Confirm wheel diameter first, then inspect width and available clearance at steering lock and through suspension travel. On a modified car, the published size may still be right in theory, but the installed setup needs its own verification.
What should I inspect before driving a 2010 Maserati GranTurismo on new tires?
Before driving a 2010 Maserati GranTurismo on new tires, confirm that the front and rear sizes match the car’s wheel package and that all four tires are mounted in the correct positions. It is also wise to inspect wheel condition, valve stems, and visible clearance around suspension components, inner liners, and fender edges.
After installation, check air pressure regularly and pay attention to any rubbing, vibration, or uneven behavior during the first miles. A car that has been stored or driven infrequently also deserves a quick inspection of suspension bushings, alignment condition, and brake components. New tires perform best when the rest of the chassis is ready for road use as well.
What should I check before a longer drive in a 2010 Maserati GranTurismo?
Before a longer drive, make sure the 2010 Maserati GranTurismo is on the correct staggered tire sizes for its 19-inch or 20-inch setup and that inflation is consistent across all four tires. Inspect tread and sidewalls for cuts, bulges, cracking, or signs of air loss, especially if the car spends long periods parked between drives.
A longer trip is also a good time to confirm that the tires are wearing evenly and that there is no contact under steering or suspension movement. On cars with recent wheel changes or suspension work, a brief local test drive before heading out can reveal issues early. Collector-minded maintenance habits still matter even on a modern grand tourer.
