The 2005 Maserati Coupe sits in the modern grand touring tradition, blending Italian styling with a performance-focused chassis and a layout that rewards careful tire selection. On this car, tire fitment is not a single-size decision, because front and rear sizes differ and the GT winter setup changes the front size again. The primary fitments are all radial 18-inch tires, with 235/40R18 and 265/35R18 used on the standard staggered arrangement, while 225/40R18 appears on the GT winter front fitment. Available choices center on blackwall performance radials from BFGoodrich and Nitto, so the real task is matching the correct size to the exact front or rear position and intended use.
Which Tire Size Is Right for The 2005 Maserati Coupe
The 2005 Maserati Coupe uses three primary tire sizes, all in radial construction on 18-inch rims. Fitment depends first on whether the tire is for the front or rear axle, and second on whether the car is using the standard staggered setup or the GT winter front arrangement. Before choosing a tire, confirm the exact sub-model and wheel position so the correct size is matched to the car's actual setup.
Fit(s): Cambiocorsa Front and GT (Summer Tires) Front
Construction: Radial|Rim: 18 in
A 235/40R18 tire is a metric radial with a nominal section width of 235 millimeters, a 40-series profile, and fitment for an 18-inch rim. On the 2005 Maserati Coupe, this size serves as a front fitment on Cambiocorsa and GT models equipped with summer tires, making it part of the car's staggered performance layout. Available choices include BFGoodrich and Nitto blackwall radials across g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2 lines. This size should be evaluated as a front-position tire, with wheel width and the car's actual setup checked before selection.
A 265/35R18 tire is a metric radial that uses a 265-millimeter nominal section width, a 35-series profile, and an 18-inch rim diameter. On the 2005 Maserati Coupe, it is the rear tire size across Cambiocorsa, GT summer, and GT winter configurations, so it carries the wider rear portion of the staggered fitment. BFGoodrich and Nitto both offer blackwall options in this size, with tire series including g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. Choosing this size means confirming it is for the rear axle and matching it to the wheel width already on the car.
A 225/40R18 tire is a metric radial with a 225-millimeter nominal section width, a 40-series aspect ratio, and fitment for an 18-inch wheel. For the 2005 Maserati Coupe, this size is used on the front of the GT winter tire setup, distinguishing it from the wider summer front fitment. BFGoodrich and Nitto offer blackwall choices here as well, including g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. This is the size to consider only when the car is using the GT winter front arrangement and the front wheel specification matches the tire.
Sub-model fitment on the 2005 Maserati Coupe varies by axle position and, in one case, by seasonal setup. Checking the exact front or rear application matters here, because the rear size stays consistent while the front size changes between the standard and GT winter arrangements.

2005 Maserati Coupe Cambiocorsa Front
The Cambiocorsa front fitment uses a 235/40R18 radial tire on an 18-inch wheel. Tire selection here centers on choosing a front-position performance radial that suits the car's staggered setup and matches the wheel width already in place.
The Cambiocorsa rear fitment uses a 265/35R18 radial tire, giving the car its wider rear footprint. That makes rear-specific size confirmation especially important when comparing available blackwall performance tires and checking wheel compatibility.
The GT front summer fitment uses the same 235/40R18 radial size found on the Cambiocorsa front. Selection is mainly about choosing among the available tire series while keeping the correct front size and 18-inch wheel fitment in place.
The GT rear summer setup uses a 265/35R18 radial tire on an 18-inch rim. That keeps the wider rear arrangement consistent, so the key step is choosing a tire intended for the rear position and verifying wheel width before mounting.
The GT winter front fitment changes to a 225/40R18 radial tire rather than the summer front size. This smaller front width should be matched carefully to the wheel and seasonal setup so the front pair remains consistent with the intended winter arrangement.
The GT winter rear fitment remains at 265/35R18 radial, just as it does on the other rear applications. The main point for selection is keeping the rear size correct while confirming that the front tires follow the winter setup rather than the summer pairing.
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 questions for the 2005 Maserati Coupe usually come down to front-versus-rear sizing, the GT summer and winter front fitments, and choosing among available radial performance tires. The FAQs below focus on exact size, wheel fitment, product selection, and practical checks before road use.
Tire Size & Fitment
What tire size fits a 2005 Maserati Coupe?
The 2005 Maserati Coupe uses a staggered 18-inch radial setup rather than one universal tire size. Front fitment is 235/40R18 on Cambiocorsa and GT summer applications, rear fitment is 265/35R18, and the GT winter front fitment uses 225/40R18 while the rear remains 265/35R18.
That means the first step is identifying the exact front or rear position and whether the car is on the standard summer arrangement or the GT winter front setup. A Maserati Coupe with replacement wheels or a mixed tire set should also have the actual wheel and tire sizes checked before any new selection is made.
What size rim does a 2005 Maserati Coupe use?
The 2005 Maserati Coupe uses 18-inch rims with all three primary tire sizes on this page. The 235/40R18 front, 265/35R18 rear, and 225/40R18 GT winter front fitments are all built around the same 18-inch wheel diameter, even though the tire widths and profiles differ.
Rim diameter is only part of the fitment picture, so it helps to confirm wheel width as well before mounting a tire. The front and rear sizes use different width ranges, and that matters even when the diameter is the same. Checking the actual wheels on the car is especially important if it has ever been changed from stock-style wheel equipment.
Why does the 2005 Maserati Coupe have more than one tire size?
More than one tire size appears on the 2005 Maserati Coupe because the car uses a staggered front-and-rear arrangement, and the GT winter setup changes the front size. The rear remains 265/35R18 across the covered configurations, while the front is either 235/40R18 or 225/40R18 depending on application.
That makes fitment more specific than simply matching the year and model. Tire choice depends on wheel position first, then the exact sub-model and seasonal setup. A buyer comparing options should avoid assuming that a front size and rear size can be interchanged just because both mount on 18-inch wheels.
Choosing the Right Tire
What should I consider when choosing a 2005 Maserati Coupe tire?
Start with the correct size for the exact axle position and setup, because the 2005 Maserati Coupe uses different front and rear sizes and a separate GT winter front fitment. From there, compare radial tire series, wheel-width compatibility, load figures where stated, and whether the car is being kept in a standard summer-style arrangement or a winter-oriented front setup.
The available choices are all blackwall radials, so the decision is less about appearance variation and more about selecting the right product within the correct size. A car with changed wheels, suspension work, or an uneven existing tire setup should have those details checked before choosing a replacement tire.
What brands offer tires for the 2005 Maserati Coupe?
Tires for the 2005 Maserati Coupe are available from BFGoodrich and Nitto in the primary 18-inch fitment sizes. BFGoodrich options include the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series, while Nitto offerings include the NT555 G2.
Brand choice should still come after confirming the correct size for the front or rear position. Once the size is settled, compare each tire's wheel-width range and general product character within that size rather than choosing by brand alone. That approach is especially helpful on a staggered setup where front and rear tires serve different roles.
What tire series are available for the 2005 Maserati Coupe?
The 2005 Maserati Coupe is supported by several radial tire series in its 18-inch sizes, including BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Nitto NT555 G2. Those series appear across the front and rear fitment sizes, giving the buyer several ways to stay within the correct dimensions.
Choosing between series is mainly a matter of matching the product to the exact size and wheel position, then comparing details such as wheel-width specification and load figures where they are stated. Keeping the front pair and rear pair consistent by size and intended use is just as important as choosing the series itself.
Restoration & Appearance
Which tire should I choose for a period-style 2005 Maserati Coupe?
A period-style approach for a 2005 Maserati Coupe still begins with the correct modern radial fitment, since this car uses 18-inch metric radial sizes rather than vintage bias-ply sizing. The key fitments are 235/40R18 front and 265/35R18 rear in the standard staggered arrangement, with 225/40R18 used on the GT winter front application.
Appearance is more restrained here because the available products are blackwall tires, which suit the Coupe's contemporary grand touring character. For owners focused on exact delivery-era presentation, it is worth confirming wheel design, seasonal setup, and period documentation for the car itself before settling on a final tire choice.
Does correct tire fitment matter for a 2005 Maserati Coupe restoration?
Correct tire fitment matters on a 2005 Maserati Coupe restoration because the car's stance and intended setup rely on a specific staggered size relationship. Using the right front and rear sizes preserves the visual balance of the car, and the GT winter front fitment adds another detail that should be matched carefully if that configuration is being recreated.
A restoration-minded buyer should verify the actual wheel set on the car before choosing tires, especially if it has changed hands or been modified. Even on a newer collector vehicle, the right dimensions do more than fill the wheel openings; they help keep the finished car faithful to its intended character and road-ready presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2005 Maserati Coupe?
Yes, modifications can affect tire fitment on a 2005 Maserati Coupe even when the tire size looks correct on paper. Aftermarket wheels, changes in wheel width, suspension alterations, or ride-height changes can all influence how a 235/40R18, 265/35R18, or 225/40R18 tire sits and clears under the car.
That is especially important on a staggered setup, where front and rear tires already differ in width and profile. Any car with non-original wheels should have the actual rim size confirmed, then checked for clearance at full steering lock and through suspension travel before a new set of tires is chosen.
What should I inspect before driving a 2005 Maserati Coupe on new tires?
Before driving a 2005 Maserati Coupe on new tires, inspect the wheel condition, verify that the correct front and rear sizes were mounted, and make sure inflation pressures are set properly for the tire and vehicle setup. It also helps to look for any immediate signs of rubbing, uneven seating on the rim, or valve stem issues after installation.
A short initial drive should be followed by another visual check for clearance and air retention, especially on a car with staggered sizing. The suspension, alignment, and brake components also deserve attention on a performance grand tourer, because worn chassis parts can affect how even a correctly sized tire behaves on the road.
How often should tires on a 2005 Maserati Coupe be inspected?
Tires on a 2005 Maserati Coupe should be inspected regularly, not just when tread wear becomes obvious. On a low-mileage or collector-kept car, age-related issues such as cracking, flat spotting from storage, cuts, bulges, or gradual air loss can matter just as much as mileage-related wear.
A practical routine is to check pressures and visible condition before drives, then give the tires a closer inspection any time the car has been stored for a long period. Cars with staggered fitments benefit from careful monitoring because front and rear tires can wear differently, making early inspection useful for catching setup or alignment issues.
