2012 Maserati Tire Fitment Guide

2012 Maserati vehicles use seven sizes across two models: 245/35R20, 285/35R20, 245/40R19, 285/40R19, 285/30R20, 285/35R19, and 295/30R20. GranTurismo uses 245/35R20, 285/35R20, 245/40R19, and 285/40R19, while Quattroporte uses 245/35R20, 245/40R19, 285/30R20, 285/35R19, and 295/30R20. Rim-width guidance is available on some products: 245/35R20 and 245/40R19 commonly fall around 8.0 to 9.5 inches, while 285/35R19 and 285/35R20 appear around 9.5 to 11.0 inches where published.

The practical takeaway is that year and make alone are not enough for a correct match. You need to identify whether your 2012 Maserati is a GranTurismo or Quattroporte and whether it wears 19-inch or 20-inch wheels, because the front sizes may overlap while the rear sizes often do not. Treat the car as a staggered-fitment application and confirm both axle sizes before moving forward.

On a 2012 Maserati, 245/35R20 is a metric radial size. The 245 is the nominal section width in millimeters, 35 is the aspect ratio, R means radial construction, and 20 is the wheel diameter in inches. That size appears on both the GranTurismo and Quattroporte, making it one of the shared front fitments across the 2012 Maserati range.

That decoding matters because modern performance cars often combine a shared front size with different rear sizes depending on model and wheel package. If your 2012 Maserati uses 245/35R20 up front, you still need to confirm the rear size rather than assuming all four corners match. It is also wise to confirm wheel width, since several 245/35R20 products are intended for wheels around 8.0 to 9.5 inches wide.

No. The 2012 Maserati GranTurismo and 2012 Maserati Quattroporte share two front sizes, 245/35R20 and 245/40R19, but their rear sizes differ. GranTurismo uses 285/35R20 or 285/40R19, while Quattroporte uses 285/30R20, 285/35R19, or 295/30R20 depending on wheel package and application.

That difference is important because the shared Maserati branding can make the cars seem more interchangeable than they are from a tire standpoint. A quick check of the door placard, the existing tire sidewall, and the actual wheel diameter will usually settle the question. Once you know the model and wheel package, the correct front and rear pairing becomes much clearer.

2012 Maserati tires are available primarily in Blackwall form, which suits the modern Italian luxury-performance character of both the GranTurismo and Quattroporte. Certain rear sizes also open up specialty looks: 285/35R20 appears in Blackwall and RWL, 285/30R20 appears in Blackwall, RWL, and Redline, and 285/35R19 appears in Blackwall and RWL.

For most owners seeking an appearance closest to how a contemporary Maserati was typically presented, Blackwall is the most natural visual choice. RWL or Redline can create a more customized look, but they shift the car away from a stock 2012 presentation. If appearance matters as much as fitment, choose the sidewall style after you have confirmed the exact front and rear size pair.

2012 Maserati tire coverage includes BFGoodrich, Nitto, and Pro-Trac, depending on size. BFGoodrich covers 245/35R20, 285/35R20, 245/40R19, and 285/35R19, Nitto appears in 245/35R20, 285/35R20, and 285/30R20, and Pro-Trac appears in 285/35R20, 285/30R20, and 285/35R19. Some sizes stay within one brand family, while others give you a broader mix of touring, all-season, or more visually distinctive choices.

Brand selection becomes more important once you know the exact size because the range is not the same across all seven fitments. Shared front sizes tend to have a more straightforward Blackwall performance-tire selection, while some model-specific rear sizes introduce RWL or Redline alternatives. If you are trying to keep all four tires visually coordinated, check both axles together before deciding.

For 2012 Maserati fitments where both are offered, BFGoodrich g-Force Sport Comp 2 and BFGoodrich g-Force Comp 2 A/S share the same general modern radial format and usually similar wheel-diameter compatibility, but they are distinct series. In 245/35R20 and 245/40R19, both appear in Blackwall form and fit wheels around 8.0 to 9.5 inches where that specification is published. In 285/35R19, the g-Force Sport Comp 2 appears in both W and Y speed-rated versions, while the g-Force Comp 2 A/S appears as a Y-rated option with a 9.5 to 11.0-inch rim-width range.

That means the choice is less about basic fit and more about which series characteristics best suit how you use the car and which exact size you need. A buyer comparing them should pay attention to speed symbol, load figure where given, and wheel-width compatibility rather than assuming every BFGoodrich option in the same nominal size is identical. On a staggered 2012 Maserati setup, consistency across front and rear matters too.

Published rim-width ranges for 2012 Maserati tire sizes vary by size and, in some cases, by product within the same size. For 245/35R20 and 245/40R19, several products fit wheels around 8.0 to 9.5 inches. For 285/35R20, published fitment reaches from 9.5 to 11.0 inches on products where that detail appears, and 285/35R19 also falls in the 9.5 to 11.0-inch range, with one product centered more tightly around 9.50 to 10.00 inches.

The key point is to match the exact tire size to the actual wheel width on your car rather than relying on section width alone. If your 2012 Maserati has been fitted with aftermarket wheels, confirm both wheel diameter and wheel width before choosing tires. That check becomes especially important on the rear axle, where the wider 285- and 295-section sizes leave less room for guesswork.

2012 Maserati fitments are modern radial sizes, and one 285/35R20 product is explicitly marked TL for tubeless use. Other products in these sizes use standard modern radial sizing language without tube-type markings, which aligns with contemporary tubeless performance fitments. Nothing in these 2012 Maserati sizes points toward a traditional tube-type collector application.

Even so, wheel condition still matters. If a 2012 Maserati is running original wheels, inspect the bead seats and valve-stem condition carefully; if it is running custom wheels, make sure the wheel was designed for tubeless radial use in the first place. Tube decisions should follow the wheel manufacturer’s guidance rather than being assumed from tire size alone.

A 2012 Maserati can use more than one tire-size combination on the same model line, but the compatibility is tied to wheel diameter. The shared 245/35R20 and model-specific 20-inch rear sizes belong on 20-inch wheels, while 245/40R19 and the model-specific 19-inch rear sizes belong on 19-inch wheels. That means a 19-inch wheel cannot interchange directly with a 20-inch tire, even if the overall look of the fitment seems similar.

For an original-wheel car, start by confirming whether the car was equipped with the 19-inch or 20-inch package. After that, verify the wheel width against the tire you plan to use, especially on the rear axle where the GranTurismo and Quattroporte diverge. The front sizes may overlap between models, but the rear pair is what usually determines whether a fitment is truly correct.

A stored 2012 Maserati should sit in a cool, dry, dark space away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment that can age rubber prematurely. Keep the tires clean, maintain inflation pressure, and move the car periodically so the same section of tread is not carrying the load for months at a time. Modern radial tires resist static flat-spotting better than older bias-ply designs, but long stationary periods still harden tires and stress sidewalls.

Owners who store a 2012 Maserati for a season often benefit from a simple routine: clean the tires, set pressure before storage, roll the car occasionally, and inspect for sidewall cracking before the next drive. If the car will be parked for an extended period, supports under the suspension can reduce prolonged loading. Good storage habits preserve both appearance and road manners when the car returns to use.

On a low-mileage 2012 Maserati, tire age is usually more important than tread depth. A sensible collector-car practice is to evaluate tires closely once they reach about five to seven years of age and to treat roughly ten years from the DOT date code as a serious replacement point, even if the tread still looks usable. That principle matters on performance tires because rubber compounds can age out before they wear out.

Maserati owners often put relatively few miles on a GranTurismo or Quattroporte, which can make old tires look deceptively healthy. Date code, sidewall condition, and how the tire holds pressure are better guides than mileage alone. If the car still rides on older tires from a previous owner, checking the date code should be one of the first steps before any sustained road use.

Tires on a 2012 Maserati deserve a quick inspection before every drive and a more careful check before any longer outing. Look for sidewall cracking, punctures, bulges, uneven wear, damage from curb contact, and any sign that pressure has dropped since the last use. Because these are low-profile radial fitments, small losses in pressure can affect handling feel more quickly than they might on a taller sidewall tire.

A regular inspection routine helps catch issues before they become expensive wheel or suspension problems. On a staggered Maserati fitment, compare both front tires to each other and both rear tires to each other so uneven wear patterns stand out. If one tire is aging differently from the others, that can be a clue to alignment, inflation, or storage conditions that deserve attention.

Yes, the tire sizes used on 2012 Maserati vehicles are modern radial performance sizes suitable for normal highway use when they are in good condition, properly inflated, and matched to the correct wheels. Speed-rated products in these fitments include W-rated tires with a 168 mph ceiling and Y-rated tires with a 186 mph ceiling, depending on size and product. Those ratings are far beyond ordinary U.S. highway speeds.

Real-world highway safety depends at least as much on tire age, inflation, alignment, and the overall condition of the car as it does on the speed symbol. A 2012 Maserati may have the performance capability to challenge the tire less than an aging suspension component or neglected brake system will challenge the driver. Make tire condition part of a complete roadworthiness check, not a stand-alone decision.

Inflation pressure for a 2012 Maserati should begin with the factory vehicle recommendation for the exact model, wheel package, and front-to-rear size combination. Some tire options also publish maximum load and pressure figures, such as 245/35R20 at 1521 pounds at 50 psi, 245/40R19 at 1653 pounds at 50 psi, and 285/35R19 up to 1930 pounds at 50 psi on certain products. Those figures describe the tire’s rated capacity, not necessarily the carmaker’s everyday operating pressure.

Use the Maserati placard or owner’s manual as the day-to-day target, then compare it with the tire manufacturer’s rating for the exact tire you choose. Do not transfer a pressure number from one size to another, especially on a staggered setup where front and rear sizes differ. A pressure that is sensible for a 245 front tire may not be appropriate for a wider rear fitment.

Before a longer drive in a 2012 Maserati, inspect all four tires for cracking, cuts, bulges, punctures, and uneven wear, then verify cold inflation pressure and confirm that the spare or mobility plan is still usable. Pay close attention to low-profile sidewalls, since impact damage from potholes can be less obvious than it is on taller tires. Also check valve stems and wheel condition while you are there.

That tire inspection should be part of a broader pre-trip review that suits a high-performance luxury car: brakes, fluids, battery condition, and suspension feel matter just as much. If the car has been sitting, the first few miles should be treated as a shakedown rather than a full-speed departure. A careful check beforehand is the easiest way to enjoy a 2012 Maserati without letting a preventable tire issue spoil the drive.
