The 2006 Maserati Spyder belongs to an era when Italian grand touring convertibles blended sharp styling, exotic character, and modern performance into a car meant to be driven rather than merely displayed. Tire choice on this model is closely tied to its front-and-rear staggered setup, with 235/40R18 and 265/35R18 sizes used on Cambiocorsa and GT summer configurations, while the GT winter front fitment changes to 225/40R18. All primary fitments are radial 18-inch tires, so the real decision is confirming the exact front or rear application and then comparing available blackwall performance-oriented tire series. That matters for handling balance, seasonal use, and maintaining the intended stance of the car.
Which Tire Size Is Right for The 2006 Maserati Spyder
The 2006 Maserati Spyder uses three primary tire sizes, and the correct choice depends on whether you are selecting for the front or rear axle and whether the car is equipped in GT summer or GT winter form. All three sizes are radial tires for 18-inch wheels, so the key step is confirming the exact sub-model position before comparing tire series, load specifications, and rim-width compatibility.
Fit(s): Cambiocorsa Front and GT (Summer Tires) Front
Construction: Radial|Rim: 18 in
235/40R18 is a metric radial size in which 235 identifies nominal section width in millimeters, 40 is the aspect ratio, R designates radial construction, and 18 is the wheel diameter in inches. On the 2006 Maserati Spyder, this size is used as a front fitment on Cambiocorsa and GT summer applications, making steering response and front-end balance part of the selection process. Available choices include BFGoodrich and Nitto blackwall tires across g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2 lines. It is the size to evaluate when matching the car's standard summer-oriented front setup on an 18-inch wheel.
265/35R18 is a metric radial size with a 265-millimeter nominal section width, a 35-series profile, radial construction, and an 18-inch rim diameter. On the 2006 Maserati Spyder, this is the rear fitment across Cambiocorsa, GT summer, and GT winter configurations, so it plays a major role in preserving the car's staggered front-to-rear setup. Product choices include BFGoodrich and Nitto blackwall designs in the g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2 families. It is the size to confirm whenever the goal is maintaining the correct rear-wheel fitment and overall balance of the car.
225/40R18 is a metric radial size where 225 gives the nominal section width in millimeters, 40 identifies the aspect ratio, and 18 indicates the required wheel diameter. On the 2006 Maserati Spyder, this size appears as the front fitment for the GT winter tire setup, distinguishing it from the wider 235/40R18 summer front application. BFGoodrich and Nitto offer blackwall choices in several performance-oriented series, including g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. It is the right size to examine when confirming a GT winter front configuration rather than the standard summer front arrangement.
Sub-model fitment on the 2006 Maserati Spyder is position-sensitive, with separate front and rear sizes and a front-size change between GT summer and GT winter configurations. Checking the exact sub-model and axle position matters before selecting a tire, even though all applications use 18-inch radial construction.

2006 Maserati Spyder Cambiocorsa Front
The Cambiocorsa front application uses a 235/40R18 radial tire, which pairs with the wider rear fitment in the car's staggered setup. Tire selection here should focus on preserving the correct front size while comparing blackwall performance series and wheel-width compatibility.
The Cambiocorsa rear application uses a 265/35R18 radial tire on an 18-inch wheel. Choosing the correct rear size is important for maintaining the intended staggered relationship with the front axle and for comparing load and rim-width specifications among available products.
The GT summer front configuration uses 235/40R18, matching the summer-oriented front fitment shared with the Cambiocorsa application. That makes the decision less about size variation and more about selecting the right tire series within the proper front specification.
The GT summer rear configuration uses 265/35R18, the same rear size used across the other covered rear applications. Tire choice here centers on keeping the correct rear size and comparing product characteristics that suit the way the car is driven.
The GT winter front application changes to a 225/40R18 radial tire rather than the wider summer front size. That makes front-position confirmation especially important, since choosing between the two front sizes depends on the exact GT seasonal setup.
The GT winter rear application retains the 265/35R18 radial rear fitment used elsewhere on the model. Selection is therefore straightforward at the rear, provided the wheel is the correct 18-inch setup and the front tire choice has been matched to the winter configuration.
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.

Questions about 2006 Maserati Spyder tires usually come down to front-versus-rear sizing, GT summer versus GT winter fitment, 18-inch wheel confirmation, and choosing among available radial tire series. The FAQs below focus on those exact decisions and the checks that matter before road use.
Tire Size & Fitment
What tire size fits a 2006 Maserati Spyder?
The 2006 Maserati Spyder uses a staggered radial setup rather than one universal tire size. Cambiocorsa and GT summer front applications use 235/40R18, all covered rear applications use 265/35R18, and the GT winter front application uses 225/40R18.
That means the first step is identifying both the sub-model configuration and whether the tire is for the front or rear axle. A front tire that is correct for GT winter is not the same as the front tire for Cambiocorsa or GT summer, even though all of them fit 18-inch wheels.
What size rim does a 2006 Maserati Spyder use?
All three primary tire sizes on the 2006 Maserati Spyder are built for 18-inch rims. The covered fitments keep the same wheel diameter across front and rear positions, even though the tire widths and profiles differ by application.
Wheel diameter is only part of the check, however. Front sizes such as 225/40R18 and 235/40R18 have different approved rim-width ranges than the 265/35R18 rear, so the actual wheel width should still be confirmed before choosing among available tire series.
Why does the 2006 Maserati Spyder have more than one tire size?
The 2006 Maserati Spyder uses more than one tire size because it has distinct front and rear fitments, and the GT winter front setup differs from the GT summer and Cambiocorsa front setup. Rear fitment remains 265/35R18, while the front is either 235/40R18 or 225/40R18.
This is a normal fitment pattern for a performance-oriented car with staggered sizing. It means a buyer should not assume that any 18-inch tire belongs on any corner of the car, and should instead verify axle position, seasonal configuration, and wheel width before selecting a tire.
Choosing the Right Tire
What should I consider when choosing a 2006 Maserati Spyder tire?
Start with the exact axle position and sub-model setup, since the 2006 Maserati Spyder uses staggered sizing and a different front tire for GT winter applications. All primary fitments are radial 18-inch tires, so the main variables become size accuracy, wheel-width compatibility, tire series, and load specifications where stated.
After the correct size is confirmed, compare the tire's intended role on the car. A front tire choice affects steering feel and balance with the rear, while a rear tire choice should match the staggered setup already in place, especially if the car has not remained on its original wheel package.
What brands offer tires for the 2006 Maserati Spyder?
The 2006 Maserati Spyder fitments covered here are available from BFGoodrich and Nitto. Within those brands, the tire selections include several radial performance-oriented lines across the front and rear sizes used on Cambiocorsa and GT configurations.
Brand choice is only one part of the decision. It still makes sense to compare the exact size, approved rim-width range, and the specific tire series available for the front or rear position so the tire suits the car's staggered layout instead of simply matching the wheel diameter.
What tire series are available for the 2006 Maserati Spyder?
Available series for the 2006 Maserati Spyder include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Nitto NT555 G2. These appear across the 225/40R18, 235/40R18, and 265/35R18 fitments used on the car.
Comparing series helps when deciding how to equip the car once the correct size is settled. A buyer should still review the specific front or rear application, wheel-width compatibility, and any stated load figures rather than assuming every series in an 18-inch size suits every position on the Spyder.
Restoration & Appearance
Which tire should I choose for a period-style 2006 Maserati Spyder?
A period-style 2006 Maserati Spyder still calls for the correct modern radial size at each position, since this car uses 18-inch metric radial fitments rather than vintage bias-ply sizing. The starting point is the proper staggered layout: 235/40R18 front and 265/35R18 rear for Cambiocorsa and GT summer, or 225/40R18 front with 265/35R18 rear for GT winter.
Because all of the available products here are blackwall radials, appearance differences come more from the tire series and overall presentation than from sidewall ornamentation. Buyers pursuing strict originality should also compare the car's current wheels and any marque-specific documentation before treating any one tire line as the definitive visual match.
Does correct tire fitment matter for a 2006 Maserati Spyder restoration?
Correct tire fitment matters on a 2006 Maserati Spyder restoration because the car's stance and front-to-rear balance depend on using the proper staggered radial sizes. A mismatched front size or an incorrect rear width can change the look of the car and move it away from its intended wheel-and-tire presentation.
Restoration-minded owners should confirm whether the car still has its original-style wheel dimensions or has been altered over time. Even when the wheel remains 18 inches, the right tire still depends on front versus rear position and on whether the GT setup is the summer or winter front configuration.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 Maserati Spyder?
Yes. Modifications can affect tire fitment on a 2006 Maserati Spyder even when the tire size appears close to the original specification. Aftermarket wheels, changes in wheel width or offset, suspension alterations, or body changes can influence how 225/40R18, 235/40R18, or 265/35R18 tires sit and clear.
Any Spyder that has been lowered, re-wheeled, or otherwise changed should be checked carefully before ordering replacement tires. Measuring the actual wheel width, confirming the mounted tire position, and inspecting fender and steering clearance are more useful than relying on the model name alone.
What should I inspect before driving a 2006 Maserati Spyder on new tires?
Before driving a 2006 Maserati Spyder on new tires, inspect tire pressure, wheel torque, visible sidewall condition, valve stems, and general tread condition across all four corners. It is also important to confirm that the correct front and rear sizes have been mounted in the proper positions on the car.
A short road test should be paired with a visual recheck for rubbing, unusual contact marks, or air loss, especially on a staggered setup. Cars that see limited use deserve extra attention because age, storage conditions, and long periods of inactivity can hide problems that are not obvious at first glance.
How should tires on a 2006 Maserati Spyder be maintained?
Tires on a 2006 Maserati Spyder should be maintained with regular pressure checks, routine visual inspections, and close attention to aging, cracking, bulges, cuts, or uneven wear. Because the car uses distinct front and rear sizes, maintenance also includes keeping each tire in its correct axle position.
Collector and fair-weather cars often accumulate age faster than mileage, so storage habits matter as much as tread depth. Keeping the Spyder away from prolonged heat, direct sunlight, and moisture and checking the tires before longer drives helps preserve both the tire condition and the car's road manners.
