The 2008 Maserati GranTurismo arrived as a grand touring coupe with Italian styling, a long-hood rear-drive stance, and the kind of road presence that makes wheel and tire choice especially noticeable. On this car, fitment centers on staggered radial sizing, with different front and rear tire widths and either 19-inch or 20-inch rim diameters depending on the wheel setup. That means the real decision is not just choosing a tire brand, but confirming the correct front and rear combination and deciding how much sidewall character matters. Blackwall options dominate, while some 285/35R20 rear tires add raised white letter or redline presentation for a more customized look.
Which Tire Size Is Right for The 2008 Maserati GranTurismo
The 2008 Maserati GranTurismo uses four primary tire sizes across a staggered front-and-rear setup, and the first step is confirming whether the car is on 19-inch or 20-inch wheels. Front tires use a 245 width and rear tires use a 285 width, so choosing the right set depends on matching both wheel diameter and axle position before comparing brands, sidewall style, or tire series.
In 245/35R20, the 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 2008 Maserati GranTurismo, this size serves the front position in a 20-inch staggered setup and keeps the low-profile look expected from a modern grand touring coupe. Available choices include BFGoodrich and Nitto in blackwall form, with 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 has 20-inch front wheels and the goal is preserving the intended front-to-rear stagger.
The 245/40R19 size uses the same 245-millimeter nominal width as the 20-inch front fitment, but with a 40-series profile and a 19-inch rim diameter. It is a radial front tire size for the 2008 Maserati GranTurismo when the car is equipped with the 19-inch wheel package rather than the 20-inch setup. BFGoodrich offers this size in blackwall designs across g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A series. It should be considered only after confirming that the car is actually using 19-inch front wheels, since the matching rear size also changes with that setup.
A 285/35R20 is a wide metric radial with a 285-millimeter nominal section width, a 35-series profile, and a 20-inch rim diameter. On the 2008 Maserati GranTurismo, this size belongs at the rear when the car uses the 20-inch staggered arrangement, giving the car a broader rear tire footprint than the front. Product choices include BFGoodrich, Nitto, and Pro-Trac, with blackwall, raised white letter, and redline sidewall treatments represented in the available lineup. This is the rear size to review when appearance and wheel presentation matter just as much as matching the correct 20-inch rear fitment.
In 285/40R19, the 285 indicates nominal width in millimeters, 40 is the aspect ratio, R marks radial construction, and 19 is the rim diameter in inches. This is the rear tire size for a 2008 Maserati GranTurismo running the 19-inch staggered wheel combination, pairing with a narrower 245/40R19 front. The larger rear width remains an important part of the car's fitment balance, even though the wheel diameter differs from the 20-inch setup. This size should be selected only after confirming a 19-inch rear wheel, since the front and rear diameters need to remain matched as a set.
Fitment on the 2008 Maserati GranTurismo is straightforward in one sense and very specific in another: the covered sub-model positions are separated into front and rear tire applications. Checking whether the tire is for the front or rear axle matters just as much as confirming whether the car is on 19-inch or 20-inch wheels.

2008 Maserati GranTurismo Base Front
The 2008 Maserati GranTurismo Base Front uses a 245-width radial tire, with either a 19-inch or 20-inch fitment depending on the wheel setup. Tire selection at the front comes down to confirming wheel diameter first, then comparing blackwall product choices and series within the correct front size.
The 2008 Maserati GranTurismo Base Rear uses the wider 285-section radial tire, again split between 19-inch and 20-inch wheel configurations. Rear selection should focus on matching the correct wheel diameter and deciding whether a traditional blackwall, raised white letter, or redline presentation suits the car's intended look.
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.
Best 2008 Maserati GranTurismo Tires for Sale
Available 2008 Maserati GranTurismo tires center on radial front and rear staggered sizes from BFGoodrich, Nitto, and Pro-Trac. Buyers can compare blackwall choices across several g-Force and NT555 series, while some 285/35R20 rear options also add raised white letter or redline styling.
For the 2008 Maserati GranTurismo, the biggest questions usually involve staggered front and rear sizing, 19-inch versus 20-inch wheel fitment, radial tire selection, and how sidewall style affects the finished look.
Tire Size & Fitment
What tire size fits a 2008 Maserati GranTurismo?
The 2008 Maserati GranTurismo uses a staggered radial setup rather than one single size at all four corners. Front fitment is either 245/40R19 or 245/35R20, while rear fitment is either 285/40R19 or 285/35R20, depending on whether the car is equipped with 19-inch or 20-inch wheels.
That makes wheel diameter the first thing to confirm before choosing tires. The front and rear sizes are not interchangeable, and the 19-inch front-and-rear combination should stay paired with its matching rear size just as the 20-inch setup should stay paired with its own rear size.
What size rim does a 2008 Maserati GranTurismo use?
A 2008 Maserati GranTurismo uses either 19-inch or 20-inch rims, with staggered front and rear tire widths on both setups. The 19-inch combination uses 245/40R19 in front and 285/40R19 in the rear, while the 20-inch combination uses 245/35R20 in front and 285/35R20 in the rear.
The important point is that tire diameter must match the wheel exactly, so a 19-inch tire cannot be mounted on a 20-inch wheel or the other way around. It also helps to verify actual wheel width before comparing products, especially if the car has aftermarket wheels or a changed wheel package.
Why does the 2008 Maserati GranTurismo have more than one tire size?
More than one tire size applies because the 2008 Maserati GranTurismo uses a staggered arrangement with narrower front tires and wider rear tires, and it was fitted with either 19-inch or 20-inch wheel diameters. That creates four primary sizes across the complete fitment picture rather than one universal size.
The practical takeaway is that the car needs both the correct axle position and the correct wheel diameter confirmed before a tire is chosen. A front size should not be selected for the rear, and a 19-inch combination should not be mixed casually with a 20-inch combination without checking the full wheel-and-tire setup.
Choosing the Right Tire
What should I consider when choosing tires for a 2008 Maserati GranTurismo?
Start with the car's exact wheel diameter and axle position, because the 2008 Maserati GranTurismo uses staggered radial sizes with different front and rear widths. Once the correct size is confirmed, compare construction details, acceptable rim-width ranges where stated, and the kind of use the car sees, whether that is touring, fair-weather driving, or occasional spirited road use.
Appearance also matters on a car like this. Most available choices are blackwall, but some 285/35R20 rear tires are offered with raised white letter or redline sidewalls, so the final decision can shape the car's visual character as much as its fitment.
What sidewall styles are available for 2008 Maserati GranTurismo tires?
Blackwall is the main sidewall style available for 2008 Maserati GranTurismo tire fitments, especially in the front sizes and in several rear options. The 285/35R20 rear size also adds sidewall variety with raised white letter and redline versions through the Pro-Trac Street Pro III line.
That means sidewall choice becomes part of the decision mainly on 20-inch rear fitment. A blackwall keeps the presentation understated and modern, while raised white letter or redline styling changes the look noticeably, so it makes sense to choose the sidewall treatment that matches the car's wheels and overall theme.
What brands offer tires for the 2008 Maserati GranTurismo?
BFGoodrich, Nitto, and Pro-Trac offer tires within the available 2008 Maserati GranTurismo fitments. BFGoodrich appears across several front and rear sizes with g-Force series choices, Nitto is available in the NT555 G2 line, and Pro-Trac appears in 285/35R20 with Street Pro III rear options.
Brand choice is best treated as part of a broader comparison rather than the only factor. It helps to look at which size each brand covers, whether the tire is front or rear fitment, what sidewall style is offered, and whether the wheel width on the car matches the tire's stated range.
Restoration & Appearance
Which tire should I choose for a period-style 2008 Maserati GranTurismo?
A period-style approach for a 2008 Maserati GranTurismo starts by preserving the correct staggered sizing and the correct 19-inch or 20-inch wheel diameter already on the car. Since this is a modern grand touring coupe with radial fitment, the most natural appearance usually comes from staying within the proper front and rear dimensions first, then selecting the tire series and sidewall treatment that suit the car's presentation.
Blackwall tires maintain the most understated look, while certain 285/35R20 rear options introduce a more customized visual statement through raised white letter or redline styling. If exact delivery-era appearance matters, it is worth checking marque references and the car's original wheel setup before making a cosmetic change.
How does tire choice affect the appearance of a 2008 Maserati GranTurismo?
Tire choice affects a 2008 Maserati GranTurismo visually through wheel diameter, sidewall height, sidewall treatment, and the front-to-rear stagger that gives the car its planted stance. A 19-inch setup and a 20-inch setup both belong to this model, but each creates a different overall presentation because the profile and wheel proportion change with the diameter.
Sidewall style matters most on the 285/35R20 rear fitment, where blackwall, raised white letter, and redline options are available. Keeping the correct stagger is just as important as choosing the sidewall look, because the car's appearance can feel out of balance if the front and rear sizing relationship is altered.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2008 Maserati GranTurismo?
Yes, modifications can affect tire fitment on a 2008 Maserati GranTurismo, especially because the car already uses a staggered setup with specific front and rear sizes. Aftermarket wheels, altered wheel widths, suspension changes, or lowering can all influence whether the intended 19-inch or 20-inch tire combination still has the proper clearance and wheel compatibility.
A modified car should be checked for actual wheel diameter, wheel width, and clearance at both steering lock and normal ride height before new tires are selected. Even when the tire size itself is correct for the model, a changed setup can alter the result enough to require closer measurement.
What should I inspect before driving a 2008 Maserati GranTurismo on new tires?
Before driving a 2008 Maserati GranTurismo on new tires, inspect basic installation and vehicle-condition items rather than focusing only on the tire sidewall. Confirm front and rear sizes are mounted in the correct positions, verify air pressure, and look over the wheels for damage or irregular bead seating after installation.
It also helps to check alignment condition, suspension wear, and clearance around the fenders and inner wheel housings. A short initial drive followed by another pressure check and a quick visual inspection can reveal rubbing, uneven seating, or other issues before the car is taken on a longer trip.
What should I check before a longer drive in a 2008 Maserati GranTurismo?
Before a longer drive, make sure the 2008 Maserati GranTurismo's tires are the correct front and rear sizes for the wheel diameter on the car and that pressures are set consistently. The tread and sidewalls should also be inspected for cuts, bulges, cracking, or signs of air loss, especially if the car is driven infrequently.
Wheel torque, alignment behavior, and overall ride feel deserve attention as well. A staggered setup puts more importance on having the correct pairings at each axle, so it is smart to catch any mismatch, uneven wear pattern, or clearance issue before highway miles turn a small problem into a larger one.
