Porsche 718 Spyder Tires

Porsche 718 Spyder models from 2020 through 2025 use two tire sizes: 245/35R20 and 295/30R20. Both sizes fit 20-inch wheels, and both are modern radial sizes. The smaller 245/35R20 size and the wider 295/30R20 size are used together as a staggered setup rather than as interchangeable alternatives.

That means a Porsche 718 Spyder owner should identify whether the tire being replaced is on the front axle or the rear axle before choosing a size. If the car already wears mixed sizes front to rear, preserve that arrangement unless you are working from factory wheel and tire specifications for a complete wheel package change.

On a Porsche 718 Spyder, 245/35R20 is a modern metric radial size. The 245 is the nominal section width in millimeters, 35 is the aspect ratio, meaning the sidewall height is 35 percent of the section width, R identifies radial construction, and 20 is the wheel diameter in inches. That size is used throughout the 2020-2025 model range.

Reading the code correctly helps avoid one of the most common mistakes on modern staggered sports cars: matching wheel diameter but missing width and profile. On a Porsche 718 Spyder, the size code must be checked along with tire position on the car, because the front and rear tires are different even though both mount on 20-inch wheels.

On a Porsche 718 Spyder, 295/30R20 identifies a wide, low-profile radial tire sized for a 20-inch wheel. The 295 is the nominal section width in millimeters, 30 is the aspect ratio, R means radial construction, and 20 is the rim diameter in inches. This size is used across the full 2020-2025 production span alongside the smaller companion size.

Because this is the wider and lower-profile of the two listed sizes, it should be matched carefully to the correct wheel position. A Porsche 718 Spyder owner replacing only one pair of tires should verify the sidewall marking on the car and keep the intended front-to-rear relationship intact rather than selecting by wheel diameter alone.

A 2023 Porsche 718 Spyder uses the same two sizes found across the 2020-2025 range: 245/35R20 and 295/30R20. Both fit 20-inch wheels, but they serve different axle positions in a staggered arrangement. The correct choice depends on whether you are replacing front tires or rear tires.

Start by reading the size molded into the sidewall of the tires currently on the car and comparing front and rear. If the car has been modified, also check the wheel itself and any service records so you are matching the actual setup on the vehicle instead of assuming both ends use the same tire.

The listed Porsche 718 Spyder tire options come from BFGoodrich and Nitto. Within those brands, the available series include BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2. All of the listed products for this application are radial blackwall tires.

That gives a Porsche 718 Spyder owner a choice between more than one brand while staying within the correct general size family. The practical step is to sort first by the required front or rear size, then compare the available series within that exact size rather than choosing purely by brand name.

The listed Porsche 718 Spyder tires are all blackwall designs. No whitewall or specialty sidewall treatment appears in the available products for these sizes. That suits the modern, performance-oriented character of the 2020-2025 Porsche 718 Spyder and keeps the focus on the correct metric radial fitment.

For a Porsche 718 Spyder owner, this means sidewall appearance is straightforward and the real selection work centers on size, axle position, and tire series. If visual consistency matters, compare both front and rear choices so the car carries the same brand family and sidewall style across the full staggered set.

The available Porsche 718 Spyder tire series listed here are BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2. All are radial tires in modern metric sizing, but they represent different product families within the overall performance tire category. The distinction here is series choice within the correct size rather than a shift between bias-ply and radial construction.

That means a Porsche 718 Spyder owner can narrow the search in two stages. First confirm whether the tire is for the 245/35R20 front or the 295/30R20 rear position, then compare the available series in that exact size so the tire’s intended performance character matches how the car is driven and maintained.

A Porsche 718 Spyder should be stored on a clean, dry surface away from direct sunlight, ozone sources, and major temperature swings when the tires are fitted. Proper inflation matters during storage, especially with low-profile 20-inch radial tires, because underinflation can encourage flat-spotting and sidewall stress. Clean tires and wheels before storage so brake dust and road residue are not left sitting on the rubber.

If the Porsche 718 Spyder will sit for extended periods, move it occasionally or support it in a way that reduces constant load on one contact patch. Owners who drive the car seasonally should also recheck pressures before the next outing, since a collector or fair-weather car can lose pressure while standing still.

Tires on a Porsche 718 Spyder should be inspected regularly even if the car is driven infrequently. Check pressures, sidewall condition, tread wear pattern, and any signs of cuts, punctures, or impact damage before road use and again after spirited driving or long storage. Low-profile radial tires can show wear or damage that is easy to miss unless the inspection is deliberate.

A practical routine is to inspect the Porsche 718 Spyder before every meaningful drive and give it a more thorough check at seasonal intervals. Pay special attention to inner shoulder wear and any mismatch in front-to-rear condition, since a staggered setup can hide developing problems if the owner only looks at the visible outer sidewalls.

A Porsche 718 Spyder tire should be replaced when it shows age cracking, impact damage, irregular wear, repeated air loss, or any structural concern, even if the tread still looks usable. Collector and enthusiast cars often age their tires out before they wear them out, especially when annual mileage is modest. Tread depth alone is not a complete measure of serviceability on a low-use performance car.

The sensible approach is to evaluate the full condition of each Porsche 718 Spyder tire rather than waiting for obvious baldness. If the car has sat for long periods, has an unknown tire age, or shows vibration and harshness that did not exist before, have the tires inspected closely and replace as a set on the affected axle when needed.

The listed Porsche 718 Spyder tires are modern radial road tires in the correct 20-inch size family for this application. Public-road safety depends on more than size alone, including tire age, condition, inflation, matching front and rear fitment, and the mechanical state of the car. A correct size on paper is only one part of a safe setup.

Before driving a Porsche 718 Spyder on public roads, make sure the tires on each axle match properly, pressures are set correctly, and there is no visible damage or abnormal wear. If the car has been stored, recently purchased, or fitted with unfamiliar wheels, give the entire tire and wheel package a careful inspection before regular use.

Before driving a Porsche 718 Spyder, check tire pressure, visible tread and sidewall condition, and the actual size installed at each axle. Confirm that the front tires match each other, the rear tires match each other, and that the car retains the intended staggered relationship between the smaller front size and wider rear size. Also look for any sign of curb damage or puncture repair concerns.

That quick inspection matters on a Porsche 718 Spyder because low-profile 20-inch tires can react noticeably to pressure loss and impact damage. If the car has been parked for a while, take the first miles gently and pay attention to vibration, pull, or steering response changes that suggest the tires need a closer evaluation.

A Porsche 718 Spyder should only be driven at speeds appropriate to the condition, age, and rating of the tires actually fitted to the car. The listed products include modern radial performance tires, but real-world speed capability is affected by inflation, load, alignment, heat, and whether the tires are fresh and sound. Tire condition always overrides theoretical capability.

For a Porsche 718 Spyder owner, the practical rule is to build speed only after confirming that the tires are recent, evenly worn, properly inflated, and correctly matched to the front and rear wheels. Any uncertainty about tire age, storage history, or previous damage is reason to keep speeds conservative until the tires have been professionally evaluated.
