The 2020 Porsche 718 Spyder sits at the focused end of the modern Porsche roadster lineup, pairing open-top driving with a distinctly performance-centered chassis and a staggered tire setup. That kind of balance makes tire choice more than a simple replacement exercise, because front and rear sizing work together to support the car’s handling character. This model uses 245/35R20 in front and 295/30R20 in back, both in radial construction on 20-inch wheels. Available choices in the front size include several BFGoodrich and Nitto blackwall performance-oriented series. The key is matching the correct position-specific size while also confirming wheel setup if the car has been altered from stock.
Which Tire Size Is Right for The 2020 Porsche 718 Spyder
The 2020 Porsche 718 Spyder uses two primary tire sizes, with one assigned to the front axle and the other to the rear. Both are radial tires for 20-inch wheels, so the first step is confirming which position you are replacing rather than choosing between alternative primary fitments. Once that is clear, the decision becomes comparing the available tire lines, specifications, and wheel compatibility for that exact front or rear size.
245/35R20 is a metric radial size in which 245 identifies the nominal section width in millimeters, 35 is the aspect ratio, R designates radial construction, and 20 is the rim diameter in inches. On the 2020 Porsche 718 Spyder, this is the front tire size, so it plays a direct role in steering feel and front-end response. Available choices in this size include BFGoodrich and Nitto blackwall performance series such as g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. Selecting this size means confirming front-wheel fitment rather than assuming the rear size is interchangeable.
295/30R20 is a metric radial size that uses a 295-millimeter nominal section width, a 30-series aspect ratio, radial construction, and a 20-inch rim diameter. On the 2020 Porsche 718 Spyder, this is the rear tire size, reflecting the car’s staggered setup rather than an alternate choice for all four corners. Its role is different from the front size, so it should be treated as a position-specific fitment tied to the rear wheel and rear clearance. Choosing this size starts with verifying that the car still retains its correct rear-wheel specification and staggered arrangement.
Fitment on the 2020 Porsche 718 Spyder is straightforward, but it is split by tire position rather than by multiple trim levels. Checking whether you need the front or rear size matters, because the car uses a staggered radial setup on 20-inch wheels.

2020 Porsche 718 Spyder Base Front
The 2020 Porsche 718 Spyder Base Front uses the front-specific radial fitment for the car’s staggered 20-inch setup. Tire selection at this position centers on choosing the correct front size and then comparing available blackwall performance tire lines that suit the car’s steering and handling role.
The 2020 Porsche 718 Spyder Base Rear uses a different radial size than the front, reflecting the Spyder’s staggered layout. That means rear tire selection should focus on the correct rear fitment first, with wheel specification and rear clearance confirmed before any substitution is considered.
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 2020 Porsche 718 Spyder?
The 2020 Porsche 718 Spyder uses a staggered tire setup, with 245/35R20 on the front and 295/30R20 on the rear. Both are radial tire sizes mounted on 20-inch wheels, so there is not one single all-around size for the car.
That means the first step is identifying whether you are replacing a front tire or a rear tire. Matching the correct position-specific size matters on a staggered Porsche, especially if the car’s wheels, suspension height, or alignment settings have been changed from the original setup.
What size rim does a 2020 Porsche 718 Spyder use?
The 2020 Porsche 718 Spyder uses 20-inch rims with both of its primary tire sizes. The front 245/35R20 and rear 295/30R20 are both built around the same rim diameter, even though the section widths and aspect ratios differ between the two positions.
Rim diameter is only part of the fitment picture on a staggered car. Wheel width and the actual front-versus-rear wheel setup should still be confirmed before replacing tires, particularly if the Spyder has aftermarket wheels or if the current wheels were swapped at some point.
Why does the 2020 Porsche 718 Spyder have more than one tire size?
The 2020 Porsche 718 Spyder has more than one tire size because it uses a staggered setup, with a narrower front tire and a wider rear tire. In this case, the front size is 245/35R20 and the rear size is 295/30R20, both in radial construction.
That arrangement means tire selection is tied to axle position rather than personal preference between two primary sizes. Replacing tires on this car starts with confirming which end of the vehicle you are working on, then checking that the wheel dimensions and overall setup still match the intended front and rear fitment.
Choosing the Right Tire
What should I consider when choosing a 245/35R20 tire for a 2020 Porsche 718 Spyder?
Choosing a 245/35R20 for a 2020 Porsche 718 Spyder starts with using the correct front size and confirming that the tire is intended for a 20-inch wheel. Available options in this size include blackwall radial choices from BFGoodrich and Nitto across several performance-oriented tire series.
After size and wheel diameter are confirmed, compare the tire series, rim-width specifications, load details where stated, and the type of driving the car actually sees. A Spyder used mainly for fair-weather road driving may call for a different product emphasis than one that spends more time on longer highway runs.
What sidewall styles are available for 2020 Porsche 718 Spyder tires?
The available 245/35R20 tire choices for the 2020 Porsche 718 Spyder use a blackwall sidewall style. That keeps the look clean and modern, which suits the contemporary performance character of the car without introducing whitewall, redline, or other vintage-oriented sidewall treatments.
Sidewall style is still worth checking because appearance can matter on an open sports car as much as raw fitment does. Once the correct size and wheel compatibility are confirmed, blackwall becomes part of the visual presentation, while the main remaining differences come from tire series, specifications, and brand choice.
What brands offer tires for the 2020 Porsche 718 Spyder?
Available front-size tires for the 2020 Porsche 718 Spyder come from BFGoodrich and Nitto. In 245/35R20, BFGoodrich appears across several g-Force series, while Nitto is represented by the NT555 G2, giving the buyer more than one performance-oriented radial option to compare.
Brand alone should not make the decision on a staggered setup like this. It is more useful to compare the exact tire series, published rim-width compatibility, and any load or weight details that matter to your intended use, while keeping the front position and 20-inch wheel requirement fixed.
Restoration & Appearance
Does correct tire fitment matter for a 2020 Porsche 718 Spyder restoration?
Correct tire fitment still matters on a 2020 Porsche 718 Spyder, even though the conversation is less about vintage bias-ply authenticity and more about preserving the car’s intended modern staggered setup. Using the proper front and rear sizes helps maintain the visual stance and fitment balance the car was designed around.
For an appearance-focused project, tire choice should begin with the correct axle-specific sizes and 20-inch wheel fitment before moving on to brand or tire series. If the car has already been modified, checking wheel dimensions and overall presentation is especially important so the finished look stays proportional and purposeful.
How does tire construction affect the appearance of a restored 2020 Porsche 718 Spyder?
On a 2020 Porsche 718 Spyder, tire construction is straightforward because the primary fitment is radial. That means appearance differences are shaped less by bias-ply versus radial concerns and more by keeping the proper low-profile front and rear sizing that gives the car its modern, planted stance.
A restoration-oriented owner will usually get the best visual result by maintaining the staggered layout and avoiding substitutions that disrupt the car’s proportions. Sidewall style is also part of the presentation, and the available front-size choices use blackwall construction that complements the Spyder’s contemporary performance look.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Porsche 718 Spyder?
Yes, modifications can affect tire fitment on a 2020 Porsche 718 Spyder. Aftermarket wheels, changes in wheel width, altered suspension height, alignment changes, or body modifications can all influence how the front 245/35R20 and rear 295/30R20 sizes sit within the available space.
A modified Spyder should have wheel diameter, wheel width, and clearance checked at both ends of the car before any replacement tire is chosen. Steering clearance up front and fender or suspension clearance at the rear deserve special attention, since a staggered setup leaves less room for guessing.
What should I inspect before driving a 2020 Porsche 718 Spyder on new tires?
Before driving a 2020 Porsche 718 Spyder on new tires, inspect basic installation and condition points such as correct front-versus-rear placement, air pressure, valve condition, wheel hardware, and visible clearance around the tire. It is also worth checking for any rubbing marks or contact points after the car is back on the ground.
A short, careful test drive is a smart next step, followed by another look at pressures and clearance. Because the Spyder uses a staggered performance setup, any mismatch in position, wheel specification, or alignment can show up quickly in the way the car tracks, steers, or responds over bumps.
What should I check before a longer drive in a 2020 Porsche 718 Spyder?
Before a longer drive in a 2020 Porsche 718 Spyder, check tire pressure, tread condition, and the sidewalls for cuts, bulges, or cracking. A quick visual inspection of both the 245/35R20 front tires and 295/30R20 rear tires helps confirm that the staggered setup is still in sound condition for road use.
Longer drives also justify checking for slow air loss and making sure the tires are wearing evenly across the tread. On a car that may see seasonal or low-mileage use, age and storage conditions matter too, so any tire that shows deterioration should be evaluated before relying on it for distance driving.
