The 2006 Maserati GranSport sits in the last chapter of Maserati’s Ferrari-era coupe development, blending Italian grand touring character with sharper, more focused road manners than the standard 4200 platform. Tire choice matters here because the car uses staggered radial fitments, and the correct size depends first on whether it is set up in the Base 19-inch front and rear arrangement or the Winter Tires 18-inch front and rear arrangement. Available choices center on modern blackwall performance radials from BFGoodrich and Nitto across several series. For a GranSport owner, the real goal is matching the tire to the car’s exact wheel setup, intended use, and visual presentation without upsetting fitment balance.
Which Tire Size Is Right for The 2006 Maserati GranSport
The 2006 Maserati GranSport uses four primary tire sizes across two staggered front-and-rear setups, all in radial construction but split between 18-inch and 19-inch wheel packages. The first thing to confirm is the exact setup on the car, because the Base configuration and Winter Tires configuration use different front and rear sizes as well as different rim diameters.
In 225/40R18, the 225 is the nominal section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 18 is the wheel diameter in inches. On the 2006 Maserati GranSport, this size serves the front position in the Winter Tires setup, where precise wheel match matters because it is part of a staggered arrangement. Available choices include blackwall radials from BFGoodrich and Nitto in g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2 lines. This size is best evaluated by confirming the car’s 18-inch front wheel package rather than assuming it applies to every GranSport.
In 265/35R18, the 265 is the nominal section width in millimeters, 35 is the aspect ratio, R indicates radial construction, and 18 identifies the wheel diameter. This size is the rear companion to the 18-inch Winter Tires front fitment on the 2006 Maserati GranSport, so it should be viewed as part of a matched staggered set rather than as a standalone substitution. Product choices include blackwall performance radials from BFGoodrich and Nitto across g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2 series. Choosing this size starts with verifying the car is actually on the 18-inch rear wheel setup.
In 235/35R19, the 235 is the nominal section width in millimeters, 35 is the aspect ratio, R denotes radial construction, and 19 is the rim diameter in inches. On the 2006 Maserati GranSport, this size is used at the front in the Base staggered setup, making wheel diameter confirmation especially important before replacement. Available blackwall options in this size include the Nitto NT555 G2 and the BFGoodrich g-Force Phenom T/A. This front size makes sense for owners retaining the 19-inch Base configuration and wanting to stay with a modern performance-oriented radial fitment.
In 265/30R19, the 265 is the nominal section width in millimeters, 30 is the aspect ratio, R marks radial construction, and 19 indicates the wheel diameter. This is the rear size paired with the 235/35R19 front fitment in the Base 2006 Maserati GranSport setup, so maintaining the correct front-to-rear relationship is part of proper selection. Because this is a low-profile rear fitment, buyers should pay close attention to the actual wheel package on the car before ordering or mounting. It is the right size to evaluate only when the GranSport retains its 19-inch rear wheel configuration.
Sub-model fitment on the 2006 Maserati GranSport is defined by front and rear positions within two different wheel packages rather than by a single universal tire size. Checking whether the car is in Base or Winter Tires configuration matters first, and then the correct front or rear position must be matched to the tire.

2006 Maserati GranSport (Winter Tires) Front
The Winter Tires front position uses a 225/40R18 radial, making it part of the GranSport’s 18-inch staggered setup. Tire selection here centers on matching the front wheel diameter and choosing among the available blackwall performance radial series.
The Winter Tires rear position uses a 265/35R18 radial, paired specifically with the 18-inch front fitment. Selection should focus on preserving the intended staggered relationship and confirming the car remains on the correct 18-inch rear wheel package.
The Base front position uses a 235/35R19 radial as part of the 19-inch staggered arrangement. That makes tire choice less about alternate sizing and more about confirming the wheel setup and selecting the preferred performance radial offering within that exact size.
The Base rear position uses a 265/30R19 radial, completing the GranSport’s 19-inch front and rear staggered fitment. Owners should verify the rear wheel diameter and keep the tire matched to the corresponding front setup rather than treating it as a universal GranSport rear size.
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 Maserati GranSport?
The 2006 Maserati GranSport uses staggered radial tire sizes rather than one universal fitment. The Base setup uses 235/35R19 in front and 265/30R19 in the rear, while the Winter Tires setup uses 225/40R18 in front and 265/35R18 in the rear.
That means the first step is identifying which wheel package is on the car and then matching the correct front or rear position. A GranSport with changed wheels, aftermarket fitments, or seasonal wheel sets should be checked carefully before replacement so the tire size matches the actual rim diameter and staggered layout.
What size rim does a 2006 Maserati GranSport use?
A 2006 Maserati GranSport uses either 18-inch or 19-inch rims, depending on the specific setup. The Winter Tires arrangement uses 18-inch front and rear wheels, while the Base arrangement uses 19-inch front and rear wheels with different staggered tire sizes at each end.
Rim diameter is the key fitment checkpoint on this car because the tire sizes are split between two wheel packages. Before selecting tires, confirm the marking on each wheel and verify that the front and rear wheels have not been mixed, replaced, or altered from the original staggered arrangement.
Why does the 2006 Maserati GranSport have more than one tire size?
The 2006 Maserati GranSport has more than one tire size because it uses staggered front and rear fitments, and it also appears in both 18-inch Winter Tires and 19-inch Base wheel setups. That creates four primary sizes across the covered configurations rather than one all-around specification.
For the owner, that means tire selection is not just about year and model. The car’s exact wheel package and axle position must be confirmed first, since using a front size in the rear, or selecting an 18-inch tire for a 19-inch wheel, creates an immediate fitment mismatch.
Choosing the Right Tire
What should I consider when choosing a 2006 Maserati GranSport tire?
Start with the exact tire size and wheel package on the car, because the 2006 Maserati GranSport uses staggered radial fitments in either 18-inch or 19-inch form. Once size is confirmed, the next decision is comparing the available product lines for the appropriate front or rear position.
Useful comparison points include rim-width compatibility where stated, load figures where stated, tire series, and the intended role of the car. A GranSport kept close to its established road setup should stay with the correct staggered dimensions, while any modified car deserves an extra check for wheel width and clearance.
What sidewall styles are available for 2006 Maserati GranSport tires?
The available 2006 Maserati GranSport tire choices in these sizes are blackwall radials. That gives the car a clean, modern performance presentation consistent across the BFGoodrich and Nitto options offered in the covered 18-inch and 19-inch sizes.
Since there is no sidewall-style split here, selection comes down more to size accuracy, wheel compatibility, and tire series than to appearance treatment. For owners concerned with the finished look, blackwall keeps the focus on the wheel design and the GranSport’s low-profile staggered stance.
What brands offer tires for the 2006 Maserati GranSport?
BFGoodrich and Nitto offer tires for the 2006 Maserati GranSport in the covered fitments. Depending on the size, choices include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and the Nitto NT555 G2.
Brand choice should be considered alongside the exact tire size needed for the front or rear position. Not every series appears in every GranSport size, so the practical comparison is brand plus series within the correct wheel diameter and axle placement rather than choosing a brand first and fitment second.
Restoration & Appearance
Which tire should I choose for a period-style 2006 Maserati GranSport?
A period-style approach for a 2006 Maserati GranSport still begins with the correct staggered radial size for the actual wheel package on the car. Because the available fitments here are modern blackwall performance radials, the visual character stays clean and contemporary rather than overtly retro.
For a car kept close to its original roadgoing presentation, preserving the proper 18-inch Winter Tires or 19-inch Base front-and-rear relationship matters more than chasing cosmetic variation. Exact originality questions are best settled with marque-specific references if the goal extends beyond correct size, stance, and general visual character.
Does correct tire fitment matter for a 2006 Maserati GranSport restoration?
Correct tire fitment matters on a 2006 Maserati GranSport because the car’s appearance and stance depend on the proper staggered relationship between front and rear sizes. Using the wrong diameter or mixing the 18-inch and 19-inch setups can change the visual balance even before road behavior becomes part of the conversation.
A restoration-minded owner should confirm wheel diameter, front and rear placement, and the overall look desired before selecting tires. Even on a newer collector car, staying with the proper size family helps preserve the GranSport’s intended proportions and avoids turning a careful restoration into a wheel-and-tire mismatch.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 Maserati GranSport?
Yes, modifications can affect tire fitment on a 2006 Maserati GranSport. Aftermarket wheels, altered offsets, suspension changes, or ride-height changes can all influence whether the correct 18-inch or 19-inch staggered tire sizes still suit the car’s actual front and rear setup.
Any GranSport that has been changed from stock-style wheel or suspension dimensions should be measured carefully before replacing tires. Pay particular attention to wheel diameter, wheel width, front-to-rear matching, and clearance at full steering lock and suspension movement so the new tires suit the car as it sits now.
What should I inspect before driving a 2006 Maserati GranSport on new tires?
Before driving a 2006 Maserati GranSport on new tires, inspect the wheel size, mounting direction, air pressure, and front-to-rear placement to be sure each tire matches its intended position. It also makes sense to check for any visible rubbing risk, wheel damage, or uneven suspension issues.
A staggered car deserves a little extra attention because front and rear sizes are not interchangeable. After installation, confirm that the steering turns freely, the tires clear the body and suspension, and the car has been set up properly if alignment or wheel changes were part of the tire replacement process.
How often should tires on a 2006 Maserati GranSport be inspected?
Tires on a 2006 Maserati GranSport should be inspected regularly, especially if the car is driven seasonally or spends long periods parked. Look for pressure loss, sidewall cracking, bulges, cuts, irregular tread wear, and any sign that front and rear tires have been rotated or positioned incorrectly.
Low-use performance cars can age their tires even when tread still looks acceptable, so visual checks before each drive are worthwhile. A more complete inspection at routine service intervals helps catch wheel damage, alignment wear, and clearance issues early, particularly on a GranSport running low-profile staggered tires.
