2014 Maserati Tire Fitment Guide

2014 Maserati vehicles use nine sizes across three models. The Ghibli uses 235/50R18, 275/45R18, 245/45R19, 275/40R19, 245/40R20, 285/35R20, 245/35R21, and 285/30R21. The GranTurismo uses 245/35R20 and 285/35R20. The Quattroporte uses 245/45R19, 275/40R19, 245/40R20, 285/35R20, 245/35R21, and 285/30R21. Rim diameters span 18, 19, 20, and 21 inches, and available rim-width guidance includes 6.5 to 8.5 inches for 235/50R18, 7.5 to 9 inches for 245/45R19, 9 to 11 inches for 275/40R19, 8 to 9.5 inches for 245/35R20 and 245/40R20, 9.5 to 11 inches for 285/35R20, and 12 inches for 275/45R18.

The practical takeaway is that year and make alone are not enough for a 2014 Maserati. You need the exact model and, in many cases, the wheel package because these cars often use staggered front-and-rear sizing. Once that is confirmed, the correct tire choice becomes much clearer and you can compare brand, sidewall style, and speed rating within the proper size instead of sorting through sizes that belong to a different Maserati model.

On a 2014 Maserati, 235/50R18 is a metric radial size. The 235 is the nominal section width in millimeters, 50 is the aspect ratio, R means radial construction, and 18 is the wheel diameter in inches. This size appears on the Ghibli and is supported by products with W speed ratings to 112 mph, with some versions carrying load figures up to 1,819 pounds at 50 psi.

That decoding matters because it tells you both the tire’s basic proportions and the wheel diameter it belongs on. A 235/50R18 cannot substitute for a 19-, 20-, or 21-inch Maserati fitment, even if the car is from the same model year. If your Ghibli uses the 18-inch setup, compare tires within this exact size and then verify that your wheel falls within the approved rim-width range before making a final choice.

No. 2014 Maserati fitments vary significantly by model. The GranTurismo uses only a 20-inch staggered pairing of 245/35R20 front and 285/35R20 rear, while the Quattroporte uses 19-, 20-, and 21-inch combinations. The Ghibli has the broadest spread, covering 18-, 19-, 20-, and 21-inch setups. The only size shared across all three models is 285/35R20.

That means a tire search for a 2014 Maserati should always start with model identification, and then move to the wheel diameter already on the car. Two cars from the same year can share one rear size but use entirely different front sizes, which is especially common on performance-oriented Italian sedans and coupes. If the wheel package has been changed over time, verify the size printed on the current tire and compare it to the wheel diameter before choosing a replacement.

Most 2014 Maserati tire sizes here are available as Blackwall radials, which suits the modern, performance-luxury character of these cars. Two 20-inch sizes add another visual option: 245/40R20 and 285/35R20 are also available with raised white letters. The other supported sizes remain Blackwall only.

For most owners, Blackwall is the natural appearance choice because it aligns with how late-model Maseratis were typically presented. Raised white letters create a more overtly performance-oriented look that some buyers may prefer, but they change the visual tone of the car more noticeably than a Blackwall tire does. If presentation matters as much as fitment, choose the correct size first and then decide whether you want a more understated or more aggressive sidewall style.

2014 Maserati sizes are covered by BFGoodrich, Nitto, Pro-Trac, and M&H Racemaster, depending on the size. BFGoodrich and Nitto appear across several of the 18-, 19-, and 20-inch fitments. Pro-Trac appears in 245/40R20 and 285/35R20, while M&H Racemaster appears in 275/45R18.

Brand choice on a 2014 Maserati is shaped heavily by the exact size rather than by the make alone. Some fitments offer several mainstream radial options, while others are much narrower and point you toward a more specialized product. That makes it useful to identify your precise front and rear sizes first, then compare the brands that serve those sizes instead of assuming the same tire line spans the entire Maserati range.

In 245/35R20 for a 2014 Maserati, BFGoodrich and Nitto both offer Blackwall radial choices with W speed ratings to 112 mph. BFGoodrich spans multiple series in this size and includes options with an 8 to 9.5-inch rim-width range, while the Nitto NT555 G2 also serves the size in an XL-rated form. Product weights fall in a close range, from about 27.14 to 29 pounds among the versions shown here.

That means the decision is less about basic fitment and more about the character of the specific tire line you prefer within the same size. If your GranTurismo uses 245/35R20 at the front, compare the tire series, load index, and wheel-width compatibility on your actual wheel before deciding. Staying inside the correct size keeps the geometry intact, while those finer differences help you narrow the tire that best matches your use.

Rim-width guidance depends on the exact 2014 Maserati size. 235/50R18 fits 6.5 to 8.5-inch wheels, 245/45R19 fits 7.5 to 9-inch wheels, 275/40R19 fits 9 to 11-inch wheels, 245/35R20 and 245/40R20 fit 8 to 9.5-inch wheels, and 285/35R20 fits 9.5 to 11-inch wheels. The 275/45R18 product shown here uses a 12-inch rim. Those ranges are specific to the tire size and product family, not a blanket rule for every Maserati wheel.

Wheel width matters because it affects sidewall shape, tread support, and how the tire sits on the car. A wheel that falls outside the approved range can alter handling feel and wear pattern even when the rim diameter is correct. Before choosing a replacement tire, match the size on the car to the actual wheel diameter and width rather than assuming any tire with the right diameter will behave correctly.

The supported 2014 Maserati sizes here are radial designs, and 285/35R20 includes a tubeless marking on one product. No tube-type markings appear in these modern metric sizes. That points buyers toward tubeless fitments rather than inner-tube use for the applications covered here.

Even so, the safest approach is to confirm the exact sidewall marking on the product you choose and make sure the wheel itself is suitable for tubeless service. A modern Maserati normally relies on a tubeless wheel-and-tire system, so the condition of the bead seat and valve stem matters just as much as the tire size. If a car has had aftermarket wheels fitted, confirm compatibility before mounting a new set.

Original 2014 Maserati wheels can only be used with tire sizes that match their actual rim diameter and suitable width. The fitments here span 18, 19, 20, and 21 inches, so an 18-inch wheel cannot accept a 19-, 20-, or 21-inch tire, and a 20-inch wheel cannot accept an 18- or 21-inch tire. Several sizes also require different wheel widths, especially as the tire gets wider at the rear of a staggered setup.

That means factory wheels remain perfectly usable when they still match the intended tire size, but they are not universal across the 2014 Maserati range. If your car still wears its original wheel package, stay with the front and rear diameters it was built around. If the wheels have been changed at some point, verify both diameter and width before assuming that another Maserati size from the same year will interchange cleanly.

A 2014 Maserati should be stored out of direct sunlight, away from electric motors, welders, furnaces, or other ozone-producing equipment, and on a clean, dry surface. Keep the tires properly inflated during storage and move the car periodically if it will sit for extended stretches. Modern radials generally tolerate storage better than older bias-ply designs, but they still age from heat, UV exposure, and long static loading.

For a collector or fair-weather Maserati, storage conditions often matter more than annual mileage. If the car will remain parked for months, rolling it occasionally helps avoid flat spotting and keeps the contact patch from taking a set. Owners who maintain a spare wheel-and-tire set should protect those tires the same way, since a pristine-looking spare can still age out if it has spent years in heat or sunlight.

On a 2014 Maserati, tire life should be judged by age and condition as much as by tread depth. A good working rule is to begin careful evaluation around five to seven years and to treat about ten years as the point where replacement deserves serious consideration, even on low-mileage collector cars. The DOT date code on the tire tells you when each tire was made.

That matters because many specialty or low-use cars accumulate very few miles but still spend years exposed to heat cycles, garage conditions, and occasional underinflation. A tire can look serviceable at a glance while hardening or developing subtle sidewall cracking. If your 2014 Maserati sees seasonal use, combine date-code checking with a hands-on inspection so age does not catch you by surprise before a longer highway trip.

Tires on a 2014 Maserati should be inspected before every drive and more thoroughly before any extended outing. Check inflation pressure, tread condition, sidewall cracking, cuts, bulges, and any sign that the tire is losing air between drives. Because these cars often run staggered, low-profile fitments, it is especially important to look for damage from curbs or potholes along the outer sidewall and bead area.

Frequent inspection is one of the simplest ways to protect both the tires and the wheels on a performance-oriented Maserati. A quick visual walkaround can catch a problem that would be easy to miss on a car that only comes out on weekends. If the tires have been sitting for a while, inspect them before driving rather than after, since pressure loss and age-related cracking usually show up long before the first mile of the day.

Yes, the supported 2014 Maserati sizes here are radial highway tires, and the products shown for these fitments carry W or Y speed ratings where ratings appear. W-rated tires are rated to 112 mph, and Y-rated tires are rated to 186 mph-plus. That places them comfortably within normal U.S. highway use when the tires are in sound condition and correctly inflated.

Real-world safety on a 2014 Maserati depends on more than speed rating alone. Tire age, air pressure, alignment, suspension condition, and brake health all matter, especially on cars with wide rear tires and low-profile sidewalls. Choose the correct size for the exact model and wheel package, then confirm that all four tires are healthy enough for service before treating any highway trip as routine.

Inflation pressure for a 2014 Maserati should start with the vehicle’s factory recommendation for its exact model and wheel package, then be checked against the tire’s own rated pressure information. Among the sizes here, some products show maximum load and pressure figures such as 1,819 pounds at 50 psi for certain 235/50R18 tires, 1,874 pounds at 50 psi for some 245/45R19 tires, 2,039 pounds at 50 psi for some 275/40R19 tires, and 1,323 pounds at 35 psi for the 275/45R18 M&H radial.

Those figures are not a universal inflation target for every 2014 Maserati. They describe the tire’s rated capacity at a stated pressure, not necessarily the pressure you should run day to day. Use the car’s placard or owner’s manual for the intended operating pressure, then make sure the tire itself is suitable for that application. Never transfer a pressure figure from one Maserati size to another just because the cars share the same model year.

Before a longer drive in a 2014 Maserati, inspect each tire for cracking, punctures, bulges, uneven wear, and proper cold inflation pressure. Confirm that the front and rear sizes match the car’s intended staggered setup, and check the spare as well if the car carries one. Pay close attention to low-profile 19-, 20-, and 21-inch fitments, since sidewall damage can be less obvious than on a taller tire.

Tires are only one part of the pre-drive routine on a modern collectible Maserati, but they are one of the easiest items to verify before leaving home. It is smart to pair the tire inspection with a quick check of brakes, fluids, battery condition, and any warning lights. When the car has been parked for a while, a careful first inspection is far more useful than assuming a low-mileage tire is automatically ready for a highway run.
