The 2010 Pontiac G6 sits at the end of Pontiac’s modern sport-sedan era, offering a blend of everyday practicality with sharper styling and a more driver-focused feel than many midsize cars of its time. For tire selection, that matters because the 2010 Pontiac G6 does not rely on one universal fitment across the lineup. It uses three primary radial sizes: 215/55R17, 225/50R17, and 225/50R18, with fitment changing by sub-model and wheel diameter. Available choices center on blackwall performance-oriented radial tires from BFGoodrich and Nitto across several g-Force and NT555 series. The key step is matching the tire to the exact trim and wheel setup before comparing style, series, and road-use priorities.
Which Tire Size Is Right for The 2010 Pontiac G6
The 2010 Pontiac G6 uses three primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. Two sizes fit 17-inch wheels, while one fits an 18-inch wheel, so the first step is confirming both the trim level and the actual wheel currently on the car before narrowing down product choices.
215/55R17 is a metric radial size in which 215 identifies the section width in millimeters, 55 is the aspect ratio, R denotes radial construction, and 17 is the wheel diameter in inches. On the 2010 Pontiac G6, this size is part of the 17-inch fitment group and suits buyers staying with the proper radial construction for that wheel setup. Available choices include BFGoodrich products in blackwall form, including the g-Force Comp 2 AS and g-Force Phenom T/A series. This size is worth selecting when the car is equipped for the 215/55R17 fitment and the goal is to keep the correct overall tire category without moving to a different wheel diameter.
225/50R17 is a metric radial size that uses a 225-millimeter nominal section width, a 50-series aspect ratio, and a 17-inch rim. For the 2010 Pontiac G6, it is one of the 17-inch primary fitments and appears across more than one sub-model, making it an important size to verify before assuming all 17-inch G6 setups are the same. Product choices include blackwall tires from BFGoodrich and Nitto, with series such as g-Force Comp 2 AS, g-Force Sport Comp 2, and NT555 G2. This size becomes the right path when the car has the corresponding 17-inch wheel setup and the owner wants to compare brands and tire character within that fitment.
225/50R18 follows the same metric radial sizing format as the 17-inch version, but the final number moves the fitment to an 18-inch wheel. On the 2010 Pontiac G6, this size is tied to 18-inch applications, so wheel diameter confirmation is essential before considering any product in this group. Available blackwall options include BFGoodrich tires in the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. This is the size to evaluate when the car is already equipped with the proper 18-inch wheel package and the goal is to stay within the correct fitment family for that setup.
Tire fitment on the 2010 Pontiac G6 varies by sub-model, and some trims use more than one primary size. Checking the exact trim matters because both tire width-profile combinations and wheel diameters change across the Base and GT configurations.

2010 Pontiac G6 Base
The 2010 Pontiac G6 Base uses two 17-inch radial fitments: 215/55R17 and 225/50R17. That means tire selection starts with confirming which wheel and tire combination is actually on the car, then comparing blackwall radial options within the correct size.
The 2010 Pontiac G6 GT can use either 225/50R17 or 225/50R18 radial tires, depending on the wheel setup. The practical difference is straightforward: confirm whether the car has 17-inch or 18-inch wheels before comparing available tire series and brand options.
The 2010 Pontiac G6 GT (Summer Only) uses the 225/50R18 radial size. Tire choice is less about sorting through multiple fitments and more about selecting the right blackwall radial product for the 18-inch wheel already on the vehicle.
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 2010 Pontiac G6?
The 2010 Pontiac G6 uses three primary tire sizes: 215/55R17, 225/50R17, and 225/50R18. All three are radial sizes, and the correct one depends on the exact sub-model and wheel package rather than the model name alone.
The first thing to confirm is whether the car has 17-inch or 18-inch wheels, then match that to the specific trim. A Base model may use either 215/55R17 or 225/50R17, while GT fitment can extend to 225/50R18, so checking the current wheel and tire placard helps prevent ordering the right width-profile combination on the wrong rim diameter.
What size rim does a 2010 Pontiac G6 use?
A 2010 Pontiac G6 uses either a 17-inch or 18-inch rim, depending on the tire size and sub-model. The 215/55R17 and 225/50R17 sizes are built for 17-inch wheels, while 225/50R18 is built for an 18-inch wheel.
Rim diameter is the most important fitment checkpoint because a 17-inch tire cannot mount on an 18-inch wheel, and an 18-inch tire cannot mount on a 17-inch wheel. It also helps to verify the actual wheel on the car, since replacement wheels or previous tire changes can blur the original trim-based fitment.
Why does the 2010 Pontiac G6 have more than one tire size?
The 2010 Pontiac G6 has more than one tire size because tire fitment changes by sub-model and wheel package. Base and GT versions do not all share the same wheel diameter or width-profile combination, so the car was offered with multiple radial sizes across the lineup.
That means the buyer decision starts with identifying the exact trim and confirming the wheel currently installed on the vehicle. Once that is clear, the size choice becomes straightforward, and the next comparison shifts to product series, brand, and intended road use rather than trying to force a single tire size across every G6 configuration.
Choosing the Right Tire
What should I consider when choosing a 2010 Pontiac G6 tire?
Start with the correct size for the exact 2010 Pontiac G6 sub-model and wheel diameter, since the car uses 215/55R17, 225/50R17, or 225/50R18 depending on configuration. After size is confirmed, compare radial construction details such as tire series, rim-width compatibility, load figures where shown, and the kind of driving the car actually sees.
A daily-driven G6 may lead you toward one type of all-season or street-performance option, while a more enthusiast-oriented setup may point you toward a different series in the same size. Sidewall appearance is simple here because the available choices are blackwall, so most of the decision comes down to fitment accuracy and product character within the correct size.
What brands offer tires for the 2010 Pontiac G6?
BFGoodrich and Nitto both offer tires for the 2010 Pontiac G6, though brand availability depends on the exact size. BFGoodrich appears across all three fitment groups, while Nitto is available in the 225/50R17 size through the NT555 G2 line.
Brand comparison only matters after the correct size is established, because not every series is offered in every G6 fitment. Once the size is narrowed down, it makes sense to compare the available choices by series, rim-width specification, load capacity when stated, and whether the tire’s overall character matches how the car is driven and maintained.
What tire series are available for the 2010 Pontiac G6?
The 2010 Pontiac G6 is served by several tire series, including BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Nitto NT555 G2. Availability varies by size, so the series you can choose from depends on whether the car uses 215/55R17, 225/50R17, or 225/50R18.
Series selection helps distinguish the personality of the tire once basic fitment is settled. A useful approach is to compare which series are offered in the correct size, then look at supporting details such as wheel-width range, load figure when given, and whether the tire suits a routine street-driven G6 or a setup with a stronger emphasis on responsive road manners.
Restoration & Appearance
Which tire should I choose for a period-style 2010 Pontiac G6?
A period-style 2010 Pontiac G6 tire choice starts with keeping the correct original fitment family for the car’s trim and wheel diameter: 215/55R17, 225/50R17, or 225/50R18. Since the available products are all blackwall radials, the visual presentation stays consistent with a clean late-2000s to early-2010s appearance.
The better comparison is not old-versus-new construction, but which modern radial series best matches how the car will be used and presented. Owners chasing a highly authentic restoration standard should also compare the current wheel and tire setup against vehicle-specific historical references, since trim packages and wheel changes over time can affect appearance as much as tire choice.
Does correct tire fitment matter for a 2010 Pontiac G6 restoration?
Correct tire fitment matters on a 2010 Pontiac G6 restoration because the car used more than one size and more than one wheel diameter. Choosing the proper 17-inch or 18-inch fitment helps preserve the intended stance, proportions, and overall visual balance of the specific Base or GT configuration.
Restoration-minded buyers should confirm both the exact trim and the wheels currently on the car before selecting tires. Even when the appearance difference seems subtle on paper, moving from one width-profile combination to another can change how the car sits in the wheel opening, so careful fitment matching is part of getting the finished look right.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2010 Pontiac G6?
Yes, modifications can affect tire fitment on a 2010 Pontiac G6 even when the tire size appears close to stock. Aftermarket wheels, changes in wheel width, altered offset, lowered suspension, or body changes can all influence how a 215/55R17, 225/50R17, or 225/50R18 tire sits and clears.
That is why the actual wheel on the car should be checked rather than relying only on trim-level assumptions. Clearance at the fender, strut, and steering range should be confirmed any time the car has been altered, especially when a previous owner may have changed wheels without keeping the original G6 size and diameter combination.
What should I inspect before driving a 2010 Pontiac G6 on new tires?
Before driving a 2010 Pontiac G6 on new tires, inspect the wheels for damage, confirm the correct tire size and rim diameter, and make sure all four tires are set to suitable pressures for the vehicle setup. It is also smart to check valve stems, lug hardware, and general mounting condition before putting miles on the car.
A quick road-use check should also include suspension condition, alignment behavior, and any signs of rubbing at full steering lock or over bumps. Fresh tires can reveal issues that old worn tires masked, so the first drives should be used to listen for contact, feel for vibration, and confirm stable tracking and braking response.
How often should tires on a 2010 Pontiac G6 be inspected?
Tires on a 2010 Pontiac G6 should be inspected regularly, not just when tread looks low. Pressure, tread wear pattern, sidewall condition, and any cuts, bulges, or punctures deserve routine attention whether the car is driven daily or spends long periods parked between outings.
A practical habit is to check them before longer drives and during normal maintenance intervals, especially on a car that may have seen wheel changes or uneven alignment wear over time. Looking early for air loss or irregular wear helps protect the correct 17-inch or 18-inch fitment and can prevent a minor problem from becoming a larger road-use issue.
