In 2006 Maserati blended Italian grand touring character with modern performance across a compact coupe and spyder range as well as the larger Quattroporte sedan. It was a year when the brand's lineup stretched from two-door sports cars to an executive four-door, but tire choice remained tightly tied to model and wheel package rather than to make alone. Across four models, 11 radial sizes appear, and the key distinction is identifying whether you have a Coupe-family car or a Quattroporte, then confirming whether it rides on 18-, 19-, or 20-inch wheels. Getting the model and wheel diameter right first is the best way to narrow the correct tire fitment.
Which Tire Size Is Right for Your 2006 Maserati
Eleven tire sizes are used across 2006 Maserati vehicles, and they vary by model rather than being shared across the full lineup. The real decision starts with confirming whether your car is a Coupe, GranSport, Spyder, or Quattroporte and then matching the correct 18-, 19-, or 20-inch rim diameter. Understanding that distinction before choosing a product saves time and helps ensure the right match.

285/35R19 is a metric radial size with a 285-millimeter section width, a 35-series aspect ratio, and a 19-inch rim diameter. BFGoodrich and Pro-Trac offer it with Blackwall and RWL sidewall styles, and speed ratings vary by product between W and Y. This size is specific to Quattroporte rear applications, so it fits buyers matching the sedan's 19-inch staggered setup and choosing between a more understated black sidewall or a more pronounced visual treatment.
Year(s): 2006|Fit(s): Quattroporte|Construction: Radial|Rim: 18 in
285/40R18 is a metric radial size using a 285-millimeter section width, a 40-series aspect ratio, and an 18-inch rim diameter. Nitto and Pro-Trac offer it with Blackwall, Redline, and RWL sidewall styles, and the available Nitto version carries a W speed rating. As a Quattroporte-specific rear size, it is the correct match for the 18-inch sedan package and gives buyers more sidewall-style choice than most of the other sizes used in 2006 Maserati vehicles.
Year(s): 2006|Fit(s): Quattroporte|Construction: Radial|Rim: 20 in
245/35R20 is a metric radial size with a 245-millimeter section width, a 35-series aspect ratio, and a 20-inch rim diameter. BFGoodrich and Nitto offer it in Blackwall styling, and the available products carry W speed ratings. This size is specific to Quattroporte applications with 20-inch front wheels, making wheel diameter confirmation especially important before selecting a tire.
Year(s): 2006|Fit(s): Quattroporte|Construction: Radial|Rim: 20 in
285/30R20 is a metric radial size with a 285-millimeter section width, a 30-series aspect ratio, and a 20-inch rim diameter. Nitto and Pro-Trac offer it with Blackwall, Redline, and RWL sidewall styles, and the available Nitto version carries a W speed rating. This is a Quattroporte-specific rear size for the 20-inch staggered setup, so it is best suited to owners confirming both the large-diameter wheel package and the sidewall look they want.
Four Maserati models are covered for 2006, and tire size varies meaningfully by model. The Coupe, GranSport, and Spyder share several 18- and 19-inch fitments, while the Quattroporte uses its own 18-, 19-, and 20-inch combinations. Select your model below to narrow the correct fitment history and tire options.
2006 Maserati Coupe
The 2006 Maserati Coupe carried the brand's Ferrari-era grand touring formula into a sleek two-door package that balanced performance with road-trip comfort. Its fitments span both 18-inch and 19-inch wheels, so identifying the wheel package is just as important as identifying the model itself.
The 2006 Maserati GranSport sharpened the Coupe formula with a more focused sporting character and a more aggressive overall presentation. Its tires mount on either 18-inch or 19-inch wheels depending on setup, with staggered front and rear sizing that should be matched carefully.
The 2006 Maserati Quattroporte was Maserati's modern luxury sport sedan, blending Italian styling with a distinctly performance-oriented personality uncommon in executive four-doors of the period. Its tires mount on 18-, 19-, or 20-inch wheels depending on configuration, and it uses its own front and rear sizes separate from the Coupe-family cars.
The 2006 Maserati Spyder delivered open-top grand touring with the same basic platform family as the Coupe, but with a different ownership character centered on top-down touring and weekend use. It uses 18-inch wheels only here, with either a 225 or 235 front depending on setup and a 265 rear.
Thirty-six products are available across 11 tire sizes for 2006 Maserati vehicles. 235/35R19, 235/40R18, 265/35R18, 225/40R18, 245/45R18, 245/35R20 and related sizes are offered by BFGoodrich, Nitto, and Pro-Trac in radial construction, with Blackwall, RWL, and Redline sidewall choices depending on size; confirm your exact size first, since speed ratings can vary within the same size.
These FAQs sort out the model-specific sizing differences across the 2006 Maserati range, explain what each metric size code means, and cover sidewall style, speed rating, setup, and long-term care for modern collector use.
Size Basics & Fitment
What tire sizes fit 2006 Maserati vehicles?
2006 Maserati vehicles use 11 sizes across four models. Coupe sizes are 235/35R19, 235/40R18, 265/30R19, 265/35R18, and 225/40R18. GranSport sizes are 225/40R18, 265/35R18, 235/35R19, and 265/30R19. Spyder sizes are 235/40R18, 265/35R18, and 225/40R18. Quattroporte sizes are 245/40R19, 245/45R18, 285/35R19, 285/40R18, 245/35R20, and 285/30R20.
The practical takeaway is that year and make alone are not enough for a 2006 Maserati. You need the model first, and in many cases you also need to confirm whether the car is on 18-, 19-, or 20-inch wheels. Where rim width ranges are available, 225/40R18 fits roughly 7.5 to 9.0 inches, 235/40R18 and 245/40R19 fit about 8.0 to 9.5 inches, 265/35R18 fits about 9.0 to 10.5 inches, 245/45R18 fits about 7.5 to 9.0 inches, 285/35R19 fits about 9.5 to 11.0 inches, 285/40R18 fits about 9.5 to 11.0 inches, and 245/35R20 fits about 8.0 to 9.5 inches.
What does 235/35R19 mean on a 2006 Maserati tire?
On a 2006 Maserati, 235/35R19 means the tire is 235 millimeters wide, has a 35-series aspect ratio, uses radial construction, and mounts on a 19-inch wheel. That size appears on the Coupe and GranSport. It is one of the lower-profile front fitments in the 2006 Maserati range, paired with a 19-inch wheel rather than an 18-inch setup.
Understanding the code helps you avoid confusing it with the similar 235/40R18, which is also a 235-millimeter front size but for an 18-inch wheel and a taller sidewall. For a 2006 Maserati owner, the critical point is that the last number, 19, is the wheel diameter and cannot be substituted casually. If your car has 19-inch front wheels, this size keeps you in the intended wheel diameter family for the Coupe or GranSport.
Do all 2006 Maserati models use the same tire size?
No, 2006 Maserati models do not all use the same tire size. The Coupe, GranSport, and Spyder share several sizes, especially in 18-inch and some 19-inch applications, but the Quattroporte uses its own larger front and rear combinations and is the only model here with 20-inch fitments. Even within the Coupe-family cars, front tire width can vary between 225 and 235 in 18-inch form.
That means the correct starting point is always the exact model, followed by the actual wheel diameter on the car. A 2006 Maserati Quattroporte owner should not assume a size used on a Coupe or Spyder will translate, and a Coupe owner should not assume every 18-inch front setup uses the same width. Checking the sidewall on the current tire and verifying the wheel itself before replacement is the safest approach.
Buying the Right Tire
What sidewall styles are available for 2006 Maserati tires?
Most 2006 Maserati tire sizes on this page are available in Blackwall form, which is the dominant look across the Coupe, GranSport, Spyder, and much of the Quattroporte range. The Quattroporte rear sizes 285/35R19, 285/40R18, and 285/30R20 also add RWL and, for some sizes, Redline options through Pro-Trac. Those visual choices are size-specific rather than spread across the entire 2006 Maserati lineup.
For a buyer trying to preserve a clean late-model European performance appearance, Blackwall is usually the most natural visual fit. RWL or Redline options can change the character of the car noticeably and tend to be a more personalized styling choice than a factory-like one on a 2006 Maserati. If appearance matters as much as fitment, compare sidewall style at the same time you confirm the exact front and rear sizes.
What brands make tires for 2006 Maserati vehicles?
2006 Maserati tire coverage here comes from BFGoodrich, Nitto, and Pro-Trac. BFGoodrich appears across many of the 18-, 19-, and 20-inch sizes, Nitto covers a broad range of key front and rear fitments, and Pro-Trac appears mainly in certain wider Quattroporte rear sizes such as 285/35R19, 285/40R18, and 285/30R20. Brand choice therefore depends in part on which 2006 Maserati model and size you need.
A Coupe, GranSport, or Spyder owner will usually be choosing primarily between BFGoodrich and Nitto in the sizes shown here, while some Quattroporte rear fitments bring Pro-Trac into the picture for alternate sidewall styling. The smartest way to narrow brand choice is to first lock in the exact size, then compare the available sidewall look, speed rating, and rim-width compatibility within that size rather than trying to choose a brand in the abstract.
What is the difference between BFGoodrich g-Force Sport COMP-2 and BFGoodrich g-Force Phenom T/A for the 2006 Maserati?
For a 2006 Maserati, BFGoodrich g-Force Sport COMP-2 and g-Force Phenom T/A often overlap in the same size, but their exact specifications can differ. In 235/40R18, for example, the Sport COMP-2 carries a 91W rating with a 1,356-pound load figure at 51 psi, while the Phenom T/A carries a 95Y rating with a 1,521-pound load figure at 50 psi. In 265/35R18, the Sport COMP-2 appears as both 93W and 97Y versions depending on product family, while the Phenom T/A is available as 97Y with a 1,609-pound load figure at 50 psi.
That comparison shows why it is worth reading the full sidewall code and load information instead of choosing only by brand name. Two BFGoodrich tires in the same nominal size can differ in speed rating, load index, and sometimes weight. For a 2006 Maserati owner, the best comparison happens inside the exact size your car uses, with attention paid to how the car is driven and whether your priority is matching the highest speed rating available in that fitment.
Fitting & Setup
What rim width do 2006 Maserati tires require?
Rim width ranges vary by size on 2006 Maserati applications. 225/40R18 fits about 7.5 to 9.0 inches, 235/40R18 and 245/40R19 fit about 8.0 to 9.5 inches, 245/45R18 fits about 7.5 to 9.0 inches, 245/35R20 fits about 8.0 to 9.5 inches, 265/35R18 fits about 9.0 to 10.5 inches, and the wider Quattroporte rear sizes 285/35R19 and 285/40R18 fit about 9.5 to 11.0 inches.
Those ranges matter because a tire that matches the correct diameter can still be wrong for the wheel width already on the car. Front and rear wheels on a 2006 Maserati are often different widths, especially on staggered setups, so measure or verify each wheel separately if there is any doubt. Staying within the approved width range helps preserve the intended tread shape and sidewall behavior.
Do 2006 Maserati tires require inner tubes?
The tire products attached to 2006 Maserati sizes here are radial performance tires without tube-type markings, and one 285/35R19 product explicitly shows TL for tubeless. That points this lineup toward modern tubeless use rather than tube-type construction. No tube-only fitment pattern appears across the sizes used on the 2006 Maserati range.
Even so, tubeless operation depends on the wheel being suitable and in good condition, especially around the bead seat and valve stem area. If your 2006 Maserati has aftermarket wheels, repaired wheels, or a car with an unknown wheel history, confirm the wheel is intended for tubeless use before mounting. A wheel inspection is more useful here than assuming every 18-, 19-, or 20-inch rim is interchangeable in setup requirements.
Can the original 2006 Maserati wheels be used with all tire sizes?
No, the original 2006 Maserati wheels cannot be treated as universal across all 11 sizes. The lineup spans 18-, 19-, and 20-inch diameters, and those wheel diameters must match the corresponding tire exactly. The Quattroporte also uses wider rear sizes than the Coupe-family cars, so wheel width and model family matter just as much as diameter.
A 2006 Maserati owner should think in complete front-and-rear packages rather than single tire sizes. If the car already wears its original wheels, matching the existing sidewall size is usually the cleanest starting point. If the car has been changed from stock at some point, verify both the wheel diameter and the wheel width before ordering replacement tires, especially on staggered cars where front and rear fitments differ substantially.
Maintenance, Storage & Longevity
How should I store a 2006 Maserati when the tires are fitted?
A 2006 Maserati should be stored in a cool, dry, dark garage away from direct sunlight, electric motors, battery chargers, furnaces, and other ozone-producing equipment that can age rubber. Keep the tires clean, maintain inflation, and move the car periodically so one section of the tread is not carrying the load for months at a time. Radials generally resist flat spotting better than old-style bias-ply tires, but any low-profile performance tire can still develop temporary shape change during long static storage.
For seasonal or collector use, the goal is to reduce stress, heat cycling, and prolonged contact pressure. If the car will sit for an extended period, some owners prefer tire cradles or stands to minimize flat spotting while still supporting the vehicle properly. A 2006 Maserati with staggered wheels should also have each tire returned to the correct corner after any storage-related service so the matched sizing stays in place.
How long do tires on a 2006 Maserati typically last?
On a 2006 Maserati, tire age usually matters more than mileage because many of these cars are driven occasionally rather than daily. A sound rule is to begin evaluating tires closely once they are around five to seven years old and to treat roughly ten years from the DOT date code as the point where replacement deserves serious consideration even if tread remains. Heat, storage conditions, and inflation history all influence how quickly the rubber ages.
That means a lightly used 2006 Maserati can still need tires well before the tread is worn out. Sidewall checking, hardening rubber, repeated air loss, and vibration after balancing are all signs age may be overtaking serviceability. Reading the DOT date code on each tire gives a far clearer picture than judging by appearance alone, especially on cars that spend long stretches in indoor storage.
How often should tires on a 2006 Maserati be inspected?
Tires on a 2006 Maserati should be inspected before every drive and again before any longer highway outing. Look for cracking, cuts, punctures, bulges, uneven wear, and pressure loss, and pay particular attention to the inside shoulder on low-profile staggered fitments where wear is easy to miss at a glance. Valve stems should also be checked as part of the inspection routine.
Frequent inspection matters because these cars often sit for periods and then return to use at speed, which can expose age-related issues quickly. A quick walkaround is not enough if the car has been stored or recently driven over rough pavement. Using a pressure gauge, checking the spare if one is carried, and looking closely at both front and rear fitments helps catch problems before they become a roadside interruption.
Restoration & Authenticity
What tires were originally fitted to the 2006 Maserati Coupe?
A 2006 Maserati Coupe belongs to the modern performance era, so radial tires were the original construction type rather than bias-ply. The Coupe uses combinations that include 18-inch and 19-inch fitments, with front and rear sizes staggered according to the wheel package on the car. That makes size accuracy and wheel diameter accuracy more important than chasing a generic replacement based only on the model name.
For a stock-appearing restoration or preservation car, the first target should be matching the original size format, front-to-rear relationship, and sidewall look appropriate to a mid-2000s Italian GT. A 2006 Maserati Coupe is recent enough that modern blackwall radial appearance is usually the authentic visual baseline. If your car has unusual wheels, export-market history, or a known factory option package, a Maserati specialist or marque club can help confirm the exact original combination.
Does correct tire fitment matter for showing a 2006 Maserati?
Yes, correct tire fitment matters for showing a 2006 Maserati, even though the car is far newer than a traditional concours-era classic. Judges and knowledgeable enthusiasts will notice incorrect front-to-rear sizing, the wrong rim diameter, or an out-of-character sidewall look. On a car from this period, overall presentation usually favors the proper low-profile radial format and a wheel-and-tire package that matches the car's original visual stance.
The practical effect is that tire size is part of authenticity, not just drivability. A Quattroporte wearing the wrong rear profile or a Coupe-family car wearing the wrong front width can look subtly off even before anyone checks the sidewall. If the car is being prepared for marque judging rather than casual display, confirm the exact fitment against the car's original specifications and event standards before mounting a new set.
What is the difference between BFGoodrich g-Force COMP-2 A/S and Nitto NT555 G2 for the 2006 Maserati?
For a 2006 Maserati, BFGoodrich g-Force COMP-2 A/S and Nitto NT555 G2 overlap in several sizes but do not always carry the same detailed specs. In 245/45R18, for instance, the Nitto NT555 G2 is a 100W XL tire with a 1,764-pound load figure at 50 psi, while the BFGoodrich g-Force COMP-2 A/S in that size is a 96W product. In 265/35R18, the Nitto appears as 97W XL with a 1,609-pound load figure at 50 psi, while the BFGoodrich g-Force COMP-2 A/S is also 97W XL but with its own construction and weight characteristics.
That means the comparison is best made size by size instead of assuming one family always mirrors the other. Both are modern radial choices that suit the overall character of a 2006 Maserati, but the exact load index, sidewall marking, and weight can shift between them. If originality of appearance matters, compare the sidewall presentation as carefully as the speed and load details before choosing.
Safety & Road Use
Are 2006 Maserati tires safe for highway driving?
Yes, the tire sizes used on 2006 Maserati vehicles here are modern radial performance tires with speed ratings that include W and Y, depending on size and product. W corresponds to 168 mph and Y corresponds to 186 mph and above in standard rating convention. Those ratings comfortably cover normal U.S. highway use, and they align with the kind of high-performance grand touring mission these Maseratis were designed around.
Real-world highway safety still depends on more than the sidewall letter. Tire age, inflation, alignment, suspension condition, and brake condition are just as important on a 2006 Maserati as the nominal speed rating itself. On an older exotic or luxury performance car, the mechanical condition of the car often becomes the limiting factor long before a properly rated modern radial tire does.
What inflation pressure should I use for 2006 Maserati tires?
Inflation pressure on a 2006 Maserati should follow the vehicle placard or owner's manual for the baseline setting, because front and rear pressures can differ on staggered applications. Several tire products here also show their maximum load at 50 or 51 psi, depending on size and product, but that is a load-and-pressure capacity figure rather than a blanket operating recommendation. Examples include 235/40R18 at 1,521 pounds at 50 psi in one product, 265/35R18 at 1,609 pounds at 50 psi in one product, and 285/40R18 at 2,039 pounds at 50 psi in one product.
The key is not to transfer a pressure figure from one size to another or from one axle to the other. A 2006 Maserati Quattroporte rear tire and a Coupe front tire can have very different operating needs even if both are high-performance radials. Start with the car's factory guidance, then confirm the tire manufacturer's pressure limits and load details for the exact size and product on the car.
What should I check before taking a 2006 Maserati on a longer drive?
Before taking a 2006 Maserati on a longer drive, inspect all four tires for cracking, punctures, bulges, unusual shoulder wear, and proper cold inflation pressure. Check the valve stems, look closely at the inside sidewalls if the car has wide rear tires, and make sure front and rear sizes are correctly matched side to side. If the car carries a spare or inflation kit, confirm that it is present and serviceable.
Tires are only one part of the pre-drive routine on a 2006 Maserati. It also makes sense to confirm fluid levels, brake feel, battery condition, and suspension composure before a trip, especially if the car has been sitting. A few careful minutes in the garage can prevent the most common age-related problems and make the drive more enjoyable once the car is out on the road.
