The 2007 Chevrolet Cobalt sits in the compact-car era when trim level and performance package had a much bigger effect on wheel and tire choice than a single model name might suggest. That matters here, because the 2007 Chevrolet Cobalt uses four different radial tire sizes across the range, from 195/60R15 on smaller-wheel cars up to 215/45R18 on the supercharged SS. The available choices also vary in character, with blackwall performance radials joined by whitewall, redline, and raised white letter options in some sizes. The key is matching the tire to the exact sub-model and wheel diameter, then deciding whether appearance, handling style, or restoration-minded presentation matters most.
Which Tire Size Is Right for The 2007 Chevrolet Cobalt
The 2007 Chevrolet Cobalt uses four primary tire sizes, and they do not apply interchangeably across the model range. Sizes vary by sub-model and wheel diameter, so the first step is confirming whether the car is an LS, LT, LTZ, SS, or SS (Supercharged), then verifying whether it carries 15-, 16-, 17-, or 18-inch wheels. Once that is settled, the real comparison becomes sidewall style, tire series, and the balance between period-inspired appearance and modern radial performance.
195/60R15 is a metric radial size: 195 is the nominal section width in millimeters, 60 is the aspect ratio, R identifies radial construction, and 15 is the wheel diameter in inches. On the 2007 Chevrolet Cobalt, this size serves the smaller-wheel end of the range and keeps the fitment centered on a 15-inch rim. Available choices include BFGoodrich and Michelin, with sidewall treatments such as wide whitewall, redline, raised white letter, and blackwall across Silvertown Radial, Radial T/A, and Primacy 3 lines. It is the right size to evaluate when the car carries the 15-inch setup and the goal is either traditional styling cues or a more contemporary road-going presentation.
205/55R16 is a metric radial size with a 205-millimeter nominal section width, a 55-series profile, radial construction, and a 16-inch rim diameter. For the 2007 Chevrolet Cobalt, this size covers certain mid-range configurations and shifts the fitment to a 16-inch wheel, so wheel confirmation matters before moving past the size itself. Product choices include BFGoodrich, Michelin, and American Classic, with blackwall and wide whitewall options and series ranging from g-Force performance tires to whitewall radials. This size makes sense when the car is built around the 16-inch wheel package and the buyer wants to compare performance-oriented tread lines against more appearance-driven alternatives.
205/50R17 uses the same 205-millimeter nominal width as the 16-inch size, but the 50-series profile and 17-inch rim change the overall fitment. On the 2007 Chevrolet Cobalt, this is the primary size for the SS and places the tire decision squarely in the performance-oriented part of the model line. BFGoodrich, American Classic, and Vredestein options are available here, mostly in blackwall form, with one whitewall alternative and series such as g-Force, Sprint Plus, and American Classic Radial. This is the size to consider when the car retains its 17-inch SS wheel setup and the choice comes down to performance-style appearance versus a more unusual custom or restoration-themed look.
215/45R18 is a metric radial size with a wider 215-millimeter nominal section, a lower 45-series profile, and an 18-inch wheel diameter. For the 2007 Chevrolet Cobalt, this size belongs to the SS (Supercharged), making wheel diameter and exact sub-model identification essential before comparing products. The available options stay focused on blackwall performance radials from BFGoodrich, including g-Force Comp 2 AS and g-Force Phenom T/A. This size is the one to evaluate when the car uses the factory-style 18-inch supercharged SS setup and the buyer wants a tire that matches that lower-profile, performance-focused stance.
Sub-model fitment on the 2007 Chevrolet Cobalt is not one-size-fits-all. Tire selection depends on identifying the exact trim first, because wheel diameter and tire size change across the LS, LT, LTZ, SS, and SS (Supercharged) lineup.

2007 Chevrolet Cobalt LS
The 2007 Chevrolet Cobalt LS uses the 195/60R15 radial size, keeping fitment straightforward around a 15-inch wheel. Tire selection then becomes a matter of choosing between blackwall, whitewall, redline, or raised white letter styling within that size.
The 2007 Chevrolet Cobalt LT can use either a 195/60R15 or 205/55R16 radial, so the actual wheel package must be confirmed before selecting a tire. That difference affects both rim diameter and the range of available tire series, sidewall styles, and performance-oriented options.
The 2007 Chevrolet Cobalt LTZ uses the 205/55R16 radial size on a 16-inch wheel. Choosing within that fitment means comparing blackwall performance radials against wide whitewall options, depending on whether the priority is road feel or appearance.
The 2007 Chevrolet Cobalt SS uses the 205/50R17 radial size, tying the car to a 17-inch wheel and a more performance-focused fitment. Tire choice centers on blackwall sport-oriented lines, with one whitewall alternative for a very different visual direction.
The 2007 Chevrolet Cobalt SS (Supercharged) uses 215/45R18, the largest primary fitment in the 2007 Cobalt range. That makes wheel confirmation especially important, and the available choices stay focused on blackwall performance radial options suited to an 18-inch 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.

The product grid is most useful for comparing the exact tire size first, then series character, sidewall treatment, and wheel-width compatibility.
2007 Chevrolet Cobalt tire questions usually come down to trim-specific sizing, wheel diameter, and how the available radial choices differ by style and use. The FAQs below focus on exact fitment, product selection, and the checks worth making before putting the car back on the road.
Tire Size & Fitment
What tire size fits a 2007 Chevrolet Cobalt?
A 2007 Chevrolet Cobalt can use 195/60R15, 205/55R16, 205/50R17, or 215/45R18, depending on the sub-model and wheel package. The LS uses 195/60R15, the LT uses either 195/60R15 or 205/55R16, the LTZ uses 205/55R16, the SS uses 205/50R17, and the SS (Supercharged) uses 215/45R18.
The most important step is matching the tire size to the exact trim and actual wheel diameter on the car. A Cobalt with changed wheels, replacement rims, or a used-car history may not still wear its original setup, so the sidewall size and wheel measurement should be checked before choosing a tire.
What size rim does a 2007 Chevrolet Cobalt use?
The 2007 Chevrolet Cobalt uses four rim diameters across the model line: 15, 16, 17, and 18 inches. The 195/60R15 fits a 15-inch rim, 205/55R16 fits a 16-inch rim, 205/50R17 fits a 17-inch rim, and 215/45R18 fits an 18-inch rim.
Rim diameter is the first fitment checkpoint because each tire size is built around a specific wheel diameter. Once that is confirmed, it also helps to compare wheel width against the tire's approved range, especially on cars with aftermarket wheels or trim levels like the LT that could have left the factory with more than one tire size.
Why does the 2007 Chevrolet Cobalt have more than one tire size?
The 2007 Chevrolet Cobalt has more than one tire size because different sub-models use different wheel packages. The range runs from 15-inch fitments on LS models to 18-inch fitments on the SS (Supercharged), with the LT, LTZ, and SS filling the middle with their own wheel and tire combinations.
That means the model name alone is not enough to choose a tire. The trim level, the wheel diameter actually on the car, and any past modifications all affect what belongs there now, so a quick check of the wheel and the existing sidewall size prevents ordering a tire meant for a different Cobalt setup.
Choosing the Right Tire
What should I consider when choosing a 2007 Chevrolet Cobalt tire?
Start with the exact tire size and wheel diameter used by the specific 2007 Chevrolet Cobalt sub-model. After that, compare the tire's construction, approved rim-width range, sidewall style, and series character, because the available choices range from straightforward blackwall radials to whitewall, redline, and raised white letter designs in certain sizes.
The right choice depends on how the car is used and how it should look. A performance-oriented SS may point a buyer toward sport radial lines, while an LS or LT owner may care more about traditional styling cues or a cleaner touring appearance, so use, wheel setup, and visual goals should be weighed together.
What sidewall styles are available for 2007 Chevrolet Cobalt tires?
Sidewall choices for the 2007 Chevrolet Cobalt include blackwall, wide whitewall, redline, and RWL, depending on size. The broadest appearance variety is found in 195/60R15, while 205/55R16 and 205/50R17 mix blackwall choices with selected whitewall options, and 215/45R18 stays focused on blackwall performance radials.
That variety gives the Cobalt owner a very different visual outcome without changing the basic fitment. Sidewall style should still be chosen within the correct tire size for the sub-model, since an appearance preference does not override wheel diameter, profile, or the tire's compatibility with the wheel already on the car.
What brands offer tires for the 2007 Chevrolet Cobalt?
Brands available for the 2007 Chevrolet Cobalt include BFGoodrich, Michelin, American Classic, and Vredestein, depending on tire size. Some sizes lean heavily toward blackwall performance tires, while others also include whitewall, redline, or raised white letter choices that change the car's appearance more than its basic fitment category.
Brand should be compared alongside size, series, and sidewall treatment rather than treated as the only decision point. A buyer looking at a 15-inch LS setup may have very different visual options than someone choosing tires for an 18-inch SS (Supercharged), so the exact Cobalt configuration still leads the process.
Restoration & Appearance
Which tire should I choose for a period-style 2007 Chevrolet Cobalt?
A period-style 2007 Chevrolet Cobalt tire starts with the correct trim-specific size, then moves to a sidewall and tire series that match the look you want. In the smaller sizes, choices such as wide whitewall, redline, and raised white letter create a distinctly different visual character from a modern blackwall touring or performance radial.
The most convincing result usually comes from keeping the right wheel diameter and profile for the sub-model rather than forcing a style from another Cobalt trim. For owners pursuing exact originality, it is worth checking period sales literature, window-sticker documentation, or marque-specific references before settling on a sidewall treatment.
How does tire construction affect the appearance of a restored 2007 Chevrolet Cobalt?
On a 2007 Chevrolet Cobalt, construction is simpler than on many older collector vehicles because the primary fitments are all radial. The visual difference comes less from bias-ply versus radial and more from sidewall treatment, tread character, and whether the tire presents as a plain blackwall, whitewall, redline, or raised white letter design.
That makes the restoration decision more about matching the car's era and personality than preserving an older construction type. An SS can look right with a performance-style blackwall, while an LS or LT may take on a more custom or nostalgic feel with whitewall or redline options in the correct size.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2007 Chevrolet Cobalt?
Yes, modifications can change tire fitment on a 2007 Chevrolet Cobalt even when the model name stays the same. Aftermarket wheels, changes in wheel width or offset, lowered suspension, and prior brake or body changes can all affect which tire size clears properly, especially on the larger 17-inch and 18-inch setups.
A modified car should be checked by measuring the actual wheel diameter and width and by inspecting clearance at the fender, strut, and steering range. That matters just as much on an LT with mixed possible fitments as it does on an SS, because the correct catalog size still has to match the car's current hardware.
What should I inspect before driving a 2007 Chevrolet Cobalt on new tires?
Before driving a 2007 Chevrolet Cobalt on new tires, inspect the wheels for damage, confirm the tire size matches the sub-model and rim diameter, and make sure inflation is set correctly for the vehicle's service requirements. It is also smart to look over the valve stems, lug torque, and basic suspension condition before heading out.
A short test drive should include checks for rubbing, vibration, pull, or unusual steering feel. Those symptoms can point to wheel damage, alignment issues, or a mismatch between the tire and wheel setup, and catching them early is especially important on cars that have sat for a while or have had wheel changes.
What should I check before a longer drive in a 2007 Chevrolet Cobalt?
Before a longer drive, a 2007 Chevrolet Cobalt should have its tire pressures checked cold, its tread and sidewalls inspected for cuts or bulges, and its wheels rechecked for any sign of looseness or damage. Cars that spend long periods parked also deserve a careful look for flat spotting, cracking, or slow air loss.
It also helps to confirm that the tire age and overall condition still match the kind of use planned for the car. Even the correct size cannot make up for old, deteriorated rubber, and a quick clearance and pressure check is worthwhile whenever the Cobalt has aftermarket wheels or sees mixed city and highway use.
