The 2005 Maserati Spyder blends early-2000s Italian grand-touring character with an open-top layout that still feels distinctly exotic. It is a car buyers and owners tend to approach with equal attention to appearance, balance, and road manners, which makes tire choice especially important. Fitment centers on 18-inch radial sizes, with a staggered 235/40R18 front and 265/35R18 rear setup in most configurations, while the GT winter front fitment shifts to 225/40R18. Available choices focus on modern blackwall performance radials from BFGoodrich and Nitto across several series. The key is matching the correct front or rear size to the exact configuration while keeping wheel width, seasonal setup, and intended use in mind.
Which Tire Size Is Right for The 2005 Maserati Spyder
The 2005 Maserati Spyder uses three primary tire sizes, and the right choice depends first on whether the car is a front or rear fitment and whether it is running the GT winter front setup. All three are radial tires on 18-inch rims, so the decision is less about construction and more about confirming position on the car, exact sub-model configuration, and the product characteristics that suit your driving use.
Fit(s): Cambiocorsa Front and GT (Summer Tires) Front
Construction: Radial|Rim: 18 in
A 235/40R18 tire uses a 235-millimeter nominal section width, a 40-series aspect ratio, radial construction, and an 18-inch rim diameter. On the 2005 Maserati Spyder, this size serves as a front fitment in the Cambiocorsa and GT summer configuration, making it part of the car's staggered setup rather than a universal all-around size. Available choices include BFGoodrich and Nitto products in blackwall form across g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2 series. It is the size to evaluate when maintaining the standard front stance and handling balance for those covered configurations.
A 265/35R18 tire carries a 265-millimeter nominal section width, a 35-series profile, radial construction, and an 18-inch rim diameter. This is the rear fitment across the covered 2005 Maserati Spyder configurations, so it plays a central role in preserving the intended staggered front-to-rear relationship. Product choices include BFGoodrich and Nitto blackwall radials in the g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2 families. It should be chosen only where the rear application calls for it, with wheel width and overall rear setup confirmed before final selection.
A 225/40R18 tire uses a 225-millimeter nominal section width, a 40-series aspect ratio, radial construction, and an 18-inch rim diameter. On the 2005 Maserati Spyder, this size appears as the front winter-tire fitment for the GT, distinguishing it from the wider summer front setup. BFGoodrich and Nitto offer blackwall options here as well, including g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2 series. It is the size to review when the car is equipped for that winter-oriented front configuration rather than the standard summer front arrangement.
Sub-model fitment on the 2005 Maserati Spyder is position-specific, and the front size changes between the GT summer and GT winter configurations while the rear remains consistent. Checking the exact front or rear application matters before choosing a tire, even though all covered fitments use 18-inch radial construction.

2005 Maserati Spyder Cambiocorsa Front
The 2005 Maserati Spyder Cambiocorsa Front uses the 235/40R18 radial size as the front half of the car's staggered setup. Tire selection here centers on choosing among the available blackwall performance radial series while keeping the front wheel width and intended road use in mind.
The 2005 Maserati Spyder Cambiocorsa Rear uses 265/35R18 radial tires at the rear. That makes rear-specific fitment the priority, with attention focused on selecting a compatible performance radial that matches the wheel setup and preserves the intended staggered arrangement.
The 2005 Maserati Spyder GT (Summer Tires) Front uses the same 235/40R18 radial front size found on the Cambiocorsa front application. Selection comes down to comparing the available blackwall performance radial series and confirming the car is still on the summer front wheel and tire setup.
The 2005 Maserati Spyder GT (Summer Tires) Rear uses 265/35R18 radial tires at the rear, matching the other covered rear applications. The practical decision is choosing the right rear tire within that size while confirming wheel width and overall front-to-rear pairing.
The 2005 Maserati Spyder GT (Winter Tires) Front shifts to a 225/40R18 radial front size rather than the wider summer front fitment. That makes configuration confirmation especially important, since the correct choice depends on whether the car is equipped with the winter front setup.
The 2005 Maserati Spyder GT (Winter Tires) Rear continues to use the 265/35R18 radial rear size. Tire selection is therefore straightforward at the rear, with the main concern being a proper match to the wheel and to the front size used on the winter setup.
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 2005 Maserati Spyder?
The 2005 Maserati Spyder uses three tire sizes across the covered configurations: 235/40R18, 265/35R18, and 225/40R18. Most applications use a staggered setup with 235/40R18 in front and 265/35R18 in the rear, while the GT winter front application uses 225/40R18 with the same 265/35R18 rear size.
The main step is confirming whether the car is a front or rear fitment and whether it is on the GT summer or GT winter front setup. Since all covered sizes mount on 18-inch rims, selection usually comes down to correct position on the car, wheel width, and matching the front and rear tire arrangement properly.
What size rim does a 2005 Maserati Spyder use?
The covered tire fitments for the 2005 Maserati Spyder all use an 18-inch rim diameter. That applies to the 235/40R18 front size, the 265/35R18 rear size, and the 225/40R18 winter front size.
Rim diameter is only the first check, because wheel width also matters when choosing among available tires. A car that still has 18-inch wheels can still need a different tire depending on whether the wheel is mounted at the front or rear and whether the Spyder is using the summer or winter front configuration.
Why does the 2005 Maserati Spyder have more than one tire size?
The 2005 Maserati Spyder has more than one tire size because it uses position-specific fitment and a staggered setup. Front applications use either 235/40R18 or 225/40R18 depending on configuration, while the rear application uses 265/35R18.
That means the right tire cannot be chosen by year, make, and model alone. The car's exact setup has to be confirmed first, especially at the front, where the GT summer and GT winter configurations differ. Once the position and configuration are clear, the remaining decision is which radial tire series best suits the car's use.
Choosing the Right Tire
What should I consider when choosing a 2005 Maserati Spyder tire?
Start with the exact size required for the tire's position on the car, since the 2005 Maserati Spyder uses different front and rear sizes and the GT winter front setup changes again. All covered fitments are 18-inch radials, so the main comparison points are correct size, wheel-width compatibility, tire series, and load specification.
After that, think about how the Spyder is actually used. A car driven mainly in fair-weather touring may lead to a different choice than one that sees more varied road conditions. Matching the proper front and rear combination matters just as much as brand selection, because the staggered setup is part of the car's overall fitment strategy.
What brands offer tires for the 2005 Maserati Spyder?
BFGoodrich and Nitto both offer tires in the covered 2005 Maserati Spyder sizes. Across 235/40R18, 265/35R18, and 225/40R18, the available lines include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Nitto NT555 G2.
Brand alone should not decide the purchase. It makes more sense to compare which series is available in the exact front or rear size needed, then check wheel-width specifications and the role the tire will play on the car. For a staggered setup like the Spyder's, consistency across the set is usually part of a well-sorted selection.
What tire series are available for the 2005 Maserati Spyder?
The available series for the 2005 Maserati Spyder include BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2. These appear across the covered 18-inch front and rear fitment sizes.
Series choice matters because it helps separate one product's character from another even when the size is the same. Once the correct front or rear fitment is confirmed, compare series by their intended use, wheel-width specification, and other product details rather than choosing only by name or by assuming one 18-inch radial is interchangeable with another.
Restoration & Appearance
Which tire should I choose for a period-style 2005 Maserati Spyder?
A period-style 2005 Maserati Spyder still needs to begin with the correct modern radial size for its exact front or rear application. Since the covered choices are all blackwall 18-inch radials, the decision usually comes down to selecting a tire series that suits the car's visual presentation while staying faithful to its contemporary grand-touring character.
Appearance should be balanced with fitment discipline. The Spyder's staggered layout means the right visual effect depends on keeping the correct front-to-rear size relationship, not just choosing an attractive tread or sidewall. For buyers pursuing a very exact historical presentation, marque-specific references can help confirm how the car was originally equipped.
Does correct tire fitment matter for a 2005 Maserati Spyder restoration?
Correct tire fitment matters on a 2005 Maserati Spyder restoration because the car uses a specific 18-inch staggered layout, and the front fitment can differ between summer and winter GT configurations. Using the wrong size can change the visual stance and move the car away from the setup intended for that configuration.
Restoration-minded buyers should verify whether the car still has its original wheel arrangement or has been altered over time. That check is especially important on a newer collector car, where later wheel swaps are common. Confirming the correct front and rear sizes first makes it much easier to choose a tire that looks appropriate and fits properly.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2005 Maserati Spyder?
Yes, modifications can affect tire fitment on a 2005 Maserati Spyder even when the wheel remains 18 inches in diameter. Aftermarket wheels, changes in wheel width, suspension alterations, and ride-height changes can all influence how a 235/40R18, 225/40R18, or 265/35R18 tire sits in the car.
A Spyder that has been lowered or fitted with non-original wheels should be checked carefully for steering, fender, and inner-clearance issues before a tire is selected. It also helps to confirm that the front and rear wheel setup still matches the intended staggered arrangement, since position-specific fitment is central to this car.
What should I inspect before driving a 2005 Maserati Spyder on new tires?
Before driving a 2005 Maserati Spyder on new tires, inspect tire pressure, wheel condition, lug torque, and the basic condition of the suspension and steering components. It is also wise to confirm that the correct size has been installed at each corner, especially because the car uses a staggered front and rear setup.
A short, careful road test is a smart next step. Listen for rubbing, feel for vibration, and check that the car tracks cleanly without unusual steering behavior. Collector and specialty cars sometimes spend long periods parked, so a fresh set of tires should be paired with a broader look at alignment, age-related component wear, and any stored-flat spotting issues.
What should I check before a longer drive in a 2005 Maserati Spyder?
Before a longer drive, confirm that the 2005 Maserati Spyder has the correct front and rear tire sizes, proper inflation, and no visible cracking, bulges, cuts, or irregular wear. Since the rear uses 265/35R18 and the front size depends on configuration, a quick position-by-position check is worth doing.
Longer trips also make wheel and clearance checks more important, especially on a car with aftermarket wheels or suspension changes. Looking over tread condition, valve stems, and signs of slow air loss can prevent roadside problems. On a low-use Spyder, tire age and general condition matter just as much as remaining tread depth.
