2012 Porsche 911 Tires
The 2012 Porsche 911 spans an unusual moment in 911 history, with late 997 cars and the newer 991 generation overlapping in the same model year. That matters at tire level, because this is not a one-size-fits-all fitment page. The 2012 Porsche 911 uses several staggered radial tire combinations across 18-, 19-, and 20-inch wheel setups, with front and rear sizes varying by generation, trim, and winter-tire configuration. Available choices range from blackwall performance radials to Pro-Trac Street Pro III options with redline or raised white letter styling in select rear sizes. The key is matching the exact sub-model, axle position, and wheel diameter before comparing tire series or appearance.
Which Tire Size Is Right for The 2012 Porsche 911
The 2012 Porsche 911 uses 10 primary tire sizes, and the correct choice depends on the exact sub-model, whether the tire is for the front or rear, and whether the car is on an 18-, 19-, or 20-inch wheel package. This is a fully radial fitment range, and many 911 variants use staggered sizing, so confirming the specific configuration comes before comparing brands, tire series, or sidewall style.
235/40R19 is a metric radial size in which 235 is the section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 19 is the rim diameter in inches. On the 2012 Porsche 911, this size serves as a front fitment on certain Carrera (991) applications, including winter-tire configurations. Product choice in this size centers on blackwall radial performance tires, with BFGoodrich currently represented. This size should be evaluated only after confirming a 19-inch front wheel setup rather than assuming it applies across all 2012 911 variants.
Explore 235/40R19 Tires245/35R20 uses a 245-millimeter section width, a 35-series profile, radial construction, and a 20-inch rim diameter. It appears as a front tire size on certain 2012 Porsche 911 Carrera (991) and Carrera S (991) applications, making it part of the newer-generation 20-inch staggered setup. Available options include blackwall radials from BFGoodrich and Nitto across g-Force and NT555 G2 series. This size is best considered after confirming that the car carries the 20-inch front wheel package, since it is not interchangeable with the 18- and 19-inch front fitments used elsewhere in the range.
Explore 245/35R20 Tires285/35R19 is a metric radial size with a 285-millimeter section width, a 35-series profile, and a 19-inch rim diameter. On the 2012 Porsche 911, it appears as a rear size for certain Carrera (991) applications, including winter-tire listings paired with a 19-inch front setup. Selection in this size includes blackwall BFGoodrich options as well as Pro-Trac Street Pro III versions in raised white letter and redline styles. It is a useful size to compare when retaining a 19-inch rear wheel package while also deciding whether the car calls for a traditional blackwall look or a more distinctive sidewall treatment.
Explore 285/35R19 Tires295/30R20 combines a 295-millimeter section width with a low 30-series profile and a 20-inch rim diameter. This rear radial size is used on certain 2012 Porsche 911 Carrera (991) and Carrera S (991) applications, where it completes the larger-diameter staggered wheel package. Its meaning is straightforward, but its role is specific: it belongs with the 20-inch rear setup rather than with the 18- or 19-inch combinations used on other 911 trims. Choosing this size starts with confirming the wheel package and rear application, especially on cars that may have seen wheel changes after delivery.
Explore 295/30R20 Tires235/35R19 is a metric radial size that uses a 235-millimeter section width, a 35-series profile, and a 19-inch wheel diameter. It serves as a front fitment on many 2012 Porsche 911 997-based and all-wheel-drive variants, including Carrera 4, Carrera 4S, GTS, Targa 4, Targa 4S, Turbo, and Turbo S applications. Available choices in this size are blackwall radials from Nitto and BFGoodrich. This is an important size to verify carefully because it appears across many trims, but only in specific front-wheel applications within the broader 2012 911 lineup.
Explore 235/35R19 Tires235/40R18 uses a 235-millimeter section width, a 40-series sidewall, radial construction, and an 18-inch rim diameter. On the 2012 Porsche 911, it appears as a front size on certain 997-based and winter-tire applications, making it part of the smaller-diameter front setup within the model range. Available products include blackwall radial choices from BFGoodrich and Nitto across g-Force, NT555 G2, and Phenom series. This size becomes relevant when the car is running 18-inch front wheels, so wheel diameter should be confirmed before comparing tread style or brand.
Explore 235/40R18 Tires265/40R18 is a metric radial size with a 265-millimeter section width, a 40-series profile, and an 18-inch rim diameter. It serves as a rear fitment on certain 2012 Porsche 911 Carrera (997) rear applications, including winter-tire pairings with 18-inch fronts. The current product presence in this size is focused on a blackwall BFGoodrich g-Force Phenom T/A. This size should be chosen only after verifying that the car uses the narrower 18-inch rear setup rather than one of the larger 19-inch rear combinations found on other 997-based 911 trims.
Explore 265/40R18 Tires295/30R19 combines a 295-millimeter section width, a 30-series profile, radial construction, and a 19-inch rim diameter. On the 2012 Porsche 911, it appears as a rear size on certain Carrera (997), Carrera 4, Carrera 4S, Targa 4, Targa 4S, and Turbo winter-tire related applications. Its low-profile construction makes wheel diameter confirmation especially important, since it should not be confused with 295/35R18 or 295/30R20. This size is most relevant when the exact rear fitment calls for a 19-inch wheel and a winter or alternate 997-era rear setup.
Explore 295/30R19 Tires305/30R19 is a wide metric radial with a 305-millimeter section width, a 30-series profile, and a 19-inch rim diameter. It is used as a rear tire on several higher-spec 2012 Porsche 911 applications, including Carrera 4 GTS, Carrera 4S, Carrera GTS, Targa 4, Targa 4S, Turbo, and Turbo S. Buyers can compare blackwall Nitto NT555 G2 options against Pro-Trac Street Pro III versions offered in raised white letter and redline form. This size is the right place to focus when the car has the wider 19-inch rear setup and the goal includes either a conventional performance look or a more custom sidewall presentation.
Explore 305/30R19 Tires295/35R18 uses a 295-millimeter section width, a 35-series profile, radial construction, and an 18-inch rim diameter.

Frequently Asked Questions
Fitment questions on the 2012 Porsche 911 usually come down to axle position, wheel diameter, and generation-specific staggered sizing. The FAQs below focus on exact tire size, radial fitment, product choice, appearance, and the checks worth making before road use.
Tire Size & Fitment
What tire size fits a 2012 Porsche 911?
The 2012 Porsche 911 does not use one universal tire size. Fitment spans 10 radial sizes: 235/40R19, 245/35R20, 285/35R19, 295/30R20, 235/35R19, 235/40R18, 265/40R18, 295/30R19, 305/30R19, and 295/35R18, depending on generation, trim, front or rear position, and winter-tire setup.
Most 2012 911 applications are staggered, so the front and rear sizes are not the same. The practical first step is to confirm the exact sub-model and axle position, then verify whether the car is on 18-, 19-, or 20-inch wheels before selecting a tire.
What size rim does a 2012 Porsche 911 use?
A 2012 Porsche 911 can use 18-inch, 19-inch, or 20-inch rims, depending on the version of the car and the specific front or rear fitment. The tire range includes 18-inch sizes such as 235/40R18 and 295/35R18, 19-inch sizes such as 235/35R19 and 305/30R19, and 20-inch sizes such as 245/35R20 and 295/30R20.
Rim diameter should be confirmed before anything else, because several sub-models share similar width numbers while using different wheel diameters. On a staggered 911, it is also important to check the front and rear separately rather than assuming both ends of the car use the same wheel size.
Why does the 2012 Porsche 911 have more than one tire size?
The 2012 Porsche 911 covers both 997-based and 991-based cars, along with Carrera, Carrera S, Carrera 4, GTS, Targa, Turbo, and winter-tire configurations. Those versions use different wheel packages and staggered front-to-rear combinations, which is why the fitment range includes multiple sizes across 18-, 19-, and 20-inch rims.
That variety means the correct tire cannot be chosen by year and model name alone. Matching the exact trim, generation, axle position, and current wheel diameter is the reliable way to avoid choosing a front size for a rear application or mixing sizes from a different setup.
Choosing the Right Tire
What should I consider when choosing a 2012 Porsche 911 tire?
Start with the exact tire size for the specific 2012 Porsche 911 sub-model and axle position, because this model year uses multiple staggered combinations. After size is confirmed, compare radial construction details such as rim-width compatibility where stated, load figures where available, tire series, and sidewall treatment in the sizes that fit the car.
The right choice depends on how the car is used and how it is set up today. A 911 on stock-diameter wheels may only need a product comparison within one size, while a car with alternate seasonal wheels or changed rear widths needs wheel and clearance checks before any tire decision.
What sidewall styles are available for 2012 Porsche 911 tires?
Blackwall is the most common sidewall style across the available 2012 Porsche 911 tire sizes. In select rear sizes, especially 285/35R19, 305/30R19, and 295/35R18, Pro-Trac Street Pro III tires are also available with redline or raised white letter sidewalls.
That means appearance can vary quite a bit depending on the exact size your 911 uses. Buyers looking for a cleaner contemporary presentation usually stay with blackwall, while redline or raised white letter options create a more customized look and should be chosen only in the sizes that match the car's rear fitment.
What brands offer tires for the 2012 Porsche 911?
BFGoodrich, Nitto, and Pro-Trac all have fitments within the 2012 Porsche 911 size range. BFGoodrich appears across several front and rear sizes in g-Force and Phenom series, Nitto is available in NT555 G2 sizes, and Pro-Trac appears in select rear applications through the Street Pro III line.
Brand choice should come after the fitment basics are settled. Once the exact size, axle position, and wheel diameter are confirmed, the useful comparison becomes tread line, sidewall style, stated rim-width range where available, and whether the tire suits the car's intended road use and visual style.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2012 Porsche 911?
Yes. A 2012 Porsche 911 is especially sensitive to fitment changes because many versions use staggered front and rear sizes and more than one wheel diameter. Aftermarket wheels, changes in rear width, altered offsets, suspension changes, or lowered ride height can all affect which tire size can be used without clearance issues.
The safest approach is to verify the wheel diameter and actual tire size currently on the car before replacing anything. It also helps to check steering clearance, fender clearance, and inner suspension clearance at both ends, particularly on cars that no longer retain their original wheel and tire layout.
What should I inspect before driving a 2012 Porsche 911 on new tires?
Check that the front and rear tires match the intended staggered setup for the exact 2012 Porsche 911 configuration. Confirm proper mounting direction if applicable, verify tire pressure, and inspect the wheels for damage, bent flanges, or signs that the tire bead may not seat correctly on the rim.
A short visual inspection under the car is also worthwhile. Look for rubbing points near liners, suspension components, and rear inner clearances, then recheck pressure after the first drives. On a 911 with mixed wheel sizes or seasonal wheel sets, confirming every size twice is better than assuming the previous combination was correct.
What should I check before a longer drive in a 2012 Porsche 911?
Before a longer drive, inspect tread condition, air pressure, sidewall condition, and the age-related health of all four tires. On a 2012 Porsche 911, it is also important to confirm that the front and rear sizes remain properly matched to the staggered setup and that no slow air loss is developing.
Longer trips put more emphasis on consistency across the full set. A careful owner should also check for vibration, irregular wear, and any signs of contact after recent wheel or tire changes. Collector or low-use 911s deserve extra attention because tires can age out long before they appear heavily worn.
