The 2024 Porsche 718 Spyder sits at the sharp end of Porsche’s modern mid-engine roadster formula, blending open-top driving with serious chassis focus. On a car with this level of balance and responsiveness, tire fitment is not a minor detail but a central part of how the car looks, turns, and puts power down. The front fitment uses 245/35R20 radial tires, while the rear uses 295/30R20 radial tires, both on 20-inch wheels. Available choices center on modern blackwall performance radials from BFGoodrich and Nitto across several series. For any 718 Spyder owner, the key is confirming front-versus-rear placement and matching tire choice to the car’s current wheel setup and intended road use.
Which Tire Size Is Right for The 2024 Porsche 718 Spyder
The 2024 Porsche 718 Spyder uses two primary tire sizes, both in radial construction on 20-inch rims. The first step is confirming whether you are selecting a front or rear tire, since the fitment is staggered rather than interchangeable. Once that is clear, the decision shifts to comparing the available performance-oriented product lines within the correct size and checking wheel width compatibility before installation.
245/35R20 is a metric radial size in which 245 refers to nominal section width in millimeters, 35 is the aspect ratio, R identifies radial construction, and 20 is the wheel diameter in inches. On the 2024 Porsche 718 Spyder, this is the front tire size and it plays an important role in steering response and overall balance. Available options include blackwall tires from BFGoodrich and Nitto across the g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2 series. Choosing within this size means comparing the intended use of each tire and confirming the wheel falls within the supported rim-width range.
295/30R20 is a metric radial size where 295 denotes nominal section width in millimeters, 30 is the aspect ratio, R indicates radial construction, and 20 identifies the wheel diameter in inches. On the 2024 Porsche 718 Spyder, this is the rear tire size, giving the car its wider rear footprint and making front-to-rear tire selection especially important. Its meaning is less about vintage sizing conventions and more about confirming exact rear fitment on a staggered 20-inch setup. This size should be evaluated strictly as a rear application and checked carefully against the actual wheel configuration on the car.
Fitment on the covered 2024 Porsche 718 Spyder sub-models is straightforward in one sense and highly specific in another. The tire choice depends on confirming whether you are working with the front or rear position, since each uses a different 20-inch radial size.

2024 Porsche 718 Spyder RS (Center Lock) Front
The 2024 Porsche 718 Spyder RS (Center Lock) Front uses the 245/35R20 radial size. Tire selection here centers on choosing the right front application, comparing the available blackwall performance series, and confirming wheel-width compatibility on the car’s center-lock 20-inch setup.
The 2024 Porsche 718 Spyder RS (Center Lock) Rear uses the 295/30R20 radial size. That makes rear fitment a separate decision from the front, so the tire should be matched to the correct rear wheel and checked for compatibility with the vehicle’s existing staggered 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.
Best 2024 Porsche 718 Spyder Tires for Sale
Available 245/35R20 choices focus on modern blackwall radial performance tires from BFGoodrich and Nitto.

Tire questions for the 2024 Porsche 718 Spyder usually come down to staggered sizing, 20-inch rim fitment, front-versus-rear selection, and how to compare the available modern radial performance tires. The FAQs below focus on those exact issues.
Tire Size & Fitment
What tire size fits a 2024 Porsche 718 Spyder?
The 2024 Porsche 718 Spyder uses a staggered tire setup with 245/35R20 in front and 295/30R20 in the rear. Both are radial sizes designed for 20-inch wheels, so the car does not use the same tire size at all four corners.
That means the first fitment check is position on the car rather than just overall model name. A front tire should be selected as a front tire, and a rear tire should be selected as a rear tire, with wheel width and the car’s current wheel configuration confirmed before mounting.
What size rim does a 2024 Porsche 718 Spyder use?
The 2024 Porsche 718 Spyder uses 20-inch rims with both of its primary tire sizes. The front 245/35R20 and rear 295/30R20 fitments share the same rim diameter even though the tires differ in width and profile.
Matching the 20-inch diameter is only the starting point. The wheel’s actual width still matters, especially on a staggered performance application, so the tire should be checked against the wheel in use rather than assuming any 20-inch wheel is automatically suitable.
Why does the 2024 Porsche 718 Spyder have more than one tire size?
The 2024 Porsche 718 Spyder uses more than one tire size because it has a staggered setup, with a narrower front tire and a wider rear tire. In this fitment, 245/35R20 is used at the front and 295/30R20 is used at the rear.
A staggered arrangement means the front and rear positions serve different roles, so size selection is not interchangeable. Tire replacement should start by identifying the axle involved, then confirming the wheel setup on the car, especially if any wheel, suspension, or alignment-related changes have been made.
Choosing the Right Tire
What should I consider when choosing a 245/35R20 tire for a 2024 Porsche 718 Spyder?
Start with the correct front size, which is 245/35R20, and confirm radial construction on a 20-inch wheel. From there, the real comparison is among the available blackwall performance tire lines, including BFGoodrich g-Force series options and the Nitto NT555 G2.
The best choice depends on how the car is used and whether the wheel matches the tire’s supported width range where stated. It also helps to compare product details such as tire series character, load-related specifications when given, and how closely the tire matches the rest of the car’s setup.
What sidewall styles are available for 2024 Porsche 718 Spyder tires?
The available 245/35R20 products for the 2024 Porsche 718 Spyder use a blackwall sidewall style. That keeps the presentation clean and modern, which suits the car’s contemporary performance-roadster character without introducing vintage-style sidewall treatments.
Sidewall style still matters even when the choice is straightforward, because it affects the overall look of the car once mounted. On this application, the more important decisions usually shift toward selecting the right tire series, confirming wheel-width compatibility, and keeping the correct front-versus-rear fitment intact.
What brands offer tires for the 2024 Porsche 718 Spyder?
Available 245/35R20 tires for the 2024 Porsche 718 Spyder come from BFGoodrich and Nitto. BFGoodrich appears across several g-Force series, while Nitto is represented by the NT555 G2, giving the front size a useful spread of modern performance-oriented choices.
Brand should be considered alongside the tire’s series, application, and wheel fitment rather than as a stand-alone decision. Comparing the supported rim-width range where stated and keeping the tire matched to the proper front position will usually matter more than choosing by brand name alone.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2024 Porsche 718 Spyder?
Yes, modifications can affect tire fitment on a 2024 Porsche 718 Spyder even when the tire size itself is correct. Changes such as aftermarket wheels, altered offsets, suspension adjustments, or ride-height changes can influence how a 245/35R20 front or 295/30R20 rear tire sits in the wheel opening.
That is especially important on a staggered 20-inch setup, where front and rear clearances are already serving different roles. Any modified car should have wheel dimensions, tire position, and steering or suspension clearance checked carefully before assuming the standard size will behave the same way.
What should I inspect before driving a 2024 Porsche 718 Spyder on new tires?
Before driving on new tires, inspect the wheel diameter and width, confirm the front and rear tires are installed in their correct positions, and check inflation, bead seating, and overall condition. It also helps to look for any rubbing risk at full steering lock or through normal suspension movement.
A short initial drive followed by a recheck is a sensible step on a car with low-profile 20-inch tires. Pay attention to air loss, unusual vibration, and any signs of contact, since a performance-oriented staggered setup leaves less room for casual assumptions about fitment.
What should I check before a longer drive in a 2024 Porsche 718 Spyder?
Before a longer drive, check tire pressure, tread condition, and the sidewalls for cuts, bulges, or impact damage. On a 2024 Porsche 718 Spyder, it is also worth confirming that the front 245/35R20 and rear 295/30R20 tires remain correctly matched to their positions.
Longer trips put more emphasis on consistency across the full setup, so any recent wheel work, alignment changes, or suspension adjustments deserve another look. A quick inspection for uneven wear and any sign of rubbing can prevent a small fitment issue from becoming a larger road-use problem.
