The 2009 Chevrolet Cobalt sits in the final years of Chevrolet’s compact front-wheel-drive sedan and coupe line, a model known for spanning basic commuter trims through more performance-focused versions. That wide spread matters when it comes to tires, because this Cobalt uses five different radial sizes depending on the exact sub-model and wheel package, from 15-inch fitments up to the SS’s 18-inch setup. Available choices range from blackwall performance-oriented radials to whitewall, redline, and raised white letter styles in certain sizes. The key is to match the exact trim and wheel diameter first, then choose the tire character that best suits stock appearance, everyday driving, or a more custom presentation.
Which Tire Size Is Right for The 2009 Chevrolet Cobalt
The 2009 Chevrolet Cobalt uses five primary tire sizes, and the correct one depends on the exact sub-model and wheel package. Rim diameter is the first thing to confirm, since this Cobalt appears with 15-inch, 16-inch, 17-inch, and 18-inch wheels. Some trims also show more than one size within the same sub-model family, so matching the exact trim level and current wheel setup comes before comparing brands, sidewall styles, or tire series.
A 195/60R15 tire is a metric radial with a 195-millimeter section width, a 60-series aspect ratio, radial construction, and fitment for a 15-inch rim. On the 2009 Chevrolet Cobalt, this size is one of the smaller-wheel factory fitments and is used on certain LS and LT configurations. Available choices include BFGoodrich and Michelin, with blackwall, wide whitewall, redline, and raised white letter sidewall treatments depending on the tire series. This size is a strong fitment starting point for buyers keeping a 15-inch wheel while deciding between a modern everyday look and a more distinctive appearance.
A 195/65R15 tire is a metric radial that uses the same 195-millimeter width as 195/60R15 but with a taller 65-series profile on a 15-inch rim. On the 2009 Chevrolet Cobalt, this size appears on certain LS applications and should be treated as a specific trim-and-wheel fitment rather than a universal 15-inch substitute. Its construction is modern radial, which suits the Cobalt’s late-model compact-car layout and everyday road use. Buyers considering this size should verify that the car still has the correct 15-inch wheel and compare the actual mounted size against the vehicle’s present clearance and overall setup.
A 205/55R16 tire is a metric radial with a 205-millimeter section width, a 55-series profile, and fitment for a 16-inch rim. On the 2009 Chevrolet Cobalt, it is used on certain LT trims and represents a common mid-range fitment between the smaller 15-inch setups and the sportier 17-inch and 18-inch combinations. Product choices include BFGoodrich, Michelin, and American Classic, with blackwall and wide whitewall styles plus several distinct tire series. This size is the right one to evaluate when the car is equipped with 16-inch wheels and the decision is more about tire character, appearance, and rim-width compatibility than size discovery.
A 205/50R17 tire is a metric radial using a 205-millimeter section width, a lower 50-series profile, and a 17-inch rim diameter. On the 2009 Chevrolet Cobalt, this size belongs to the LT with Sport Package, making it a trim-specific fitment rather than a general upgrade for every Cobalt. Available products include BFGoodrich, American Classic, and Vredestein, with mostly blackwall offerings plus a wide whitewall option for a more unusual visual treatment. This size deserves close attention from buyers who want to preserve the sport-package wheel setup or compare performance-oriented series without moving away from the correct 17-inch format.
A 225/40R18 tire is a metric radial with a wider 225-millimeter section width, a low 40-series profile, and fitment for an 18-inch rim. On the 2009 Chevrolet Cobalt, this size is tied to the SS and reflects that model’s larger-wheel, more aggressive tire package. Product choices in this size include BFGoodrich and Nitto, all in blackwall form across several performance-focused radial series. This is the size to pursue only when the car has the proper 18-inch wheel setup, and it should be evaluated with close attention to wheel width, suspension condition, and clearance on any modified or replacement wheel package.
Tire fitment on the 2009 Chevrolet Cobalt varies by sub-model, and in some cases even within the same trim family. Checking the exact trim and wheel diameter matters before choosing a tire, because the difference between a 15-inch LS setup and an 18-inch SS setup is substantial.

2009 Chevrolet Cobalt LS
The 2009 Chevrolet Cobalt LS uses 15-inch radial fitments, but it appears with two different size combinations within that trim. Tire selection starts with confirming which 15-inch size is on the car now, then comparing sidewall style and tire-series options where that size is available.
The 2009 Chevrolet Cobalt LT (1LT) appears with either a 15-inch or 16-inch radial setup, so this trim cannot be matched by trim name alone. Wheel diameter should be confirmed first, since that determines whether the next decision is among 195/60R15 choices or 205/55R16 options.
The 2009 Chevrolet Cobalt LT (2LT) uses a 16-inch radial tire setup. That makes tire selection more straightforward, with the focus shifting from fitment identification to comparing the available blackwall and wide whitewall choices within the correct 205/55R16 size.
The 2009 Chevrolet Cobalt LT w/Sport Pkg. uses a 17-inch radial tire size that is distinct from the standard LT fitments. Tire choice here centers on keeping the proper sport-package sizing while comparing available blackwall performance styles and the whitewall alternative in 205/50R17.
The 2009 Chevrolet Cobalt SS uses the largest primary fitment in this range, with an 18-inch radial tire size. That makes wheel confirmation especially important, and buyers should compare the available blackwall performance-oriented series with attention to wheel width and overall vehicle 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.
Best 2009 Chevrolet Cobalt Tires for Sale
Available 2009 Chevrolet Cobalt tire choices vary by size, with BFGoodrich appearing across much of the range alongside Michelin, American Classic, Vredestein, and Nitto. Depending on size, the product grid includes blackwall, wide whitewall, redline, and raised white letter radials across several distinct tire series.
Tire questions for the 2009 Chevrolet Cobalt usually come down to trim-specific sizing, wheel diameter, radial tire selection, appearance choices, and checking fitment on cars that may no longer wear their original wheel package.
Tire Size & Fitment
What tire size fits a 2009 Chevrolet Cobalt?
The 2009 Chevrolet Cobalt uses five primary tire sizes: 195/60R15, 195/65R15, 205/55R16, 205/50R17, and 225/40R18. All are radial sizes, and the correct one depends on the exact sub-model and wheel package rather than the Cobalt name alone.
The practical first step is to confirm the car’s trim and actual wheel diameter. An LS, an LT with Sport Package, and an SS do not share the same tire fitment, and even some LS and LT versions appear with more than one size. Matching the current wheel setup prevents selecting the right tire in the wrong rim diameter.
What size rim does a 2009 Chevrolet Cobalt use?
A 2009 Chevrolet Cobalt can use 15-inch, 16-inch, 17-inch, or 18-inch rims depending on the sub-model and tire size. The 15-inch fitments correspond to 195/60R15 and 195/65R15, while 205/55R16, 205/50R17, and 225/40R18 match the larger wheel diameters.
Rim diameter is the most important fitment checkpoint because a tire must match the wheel it mounts to. Once diameter is confirmed, wheel width also matters, especially on the larger 17-inch and 18-inch sizes. Cars with replacement wheels should be checked carefully instead of assuming the current setup still matches original trim-based sizing.
Why does the 2009 Chevrolet Cobalt have more than one tire size?
The 2009 Chevrolet Cobalt was offered in several trims, and those trims used different wheel-and-tire packages. LS and some LT versions use smaller 15-inch or 16-inch sizes, the LT with Sport Package moves to 205/50R17, and the SS uses 225/40R18.
That means the tire decision starts with identifying the exact sub-model and then confirming the wheels currently on the car. It is common for a used compact car to have had wheels changed over time, so checking the sidewall size and wheel diameter on the vehicle is more useful than relying on model name alone.
Choosing the Right Tire
What should I consider when choosing a tire for a 2009 Chevrolet Cobalt?
Start with the correct size for the trim and wheel diameter, because the 2009 Chevrolet Cobalt uses five different primary radial fitments. After that, compare the tire’s intended character, whether that means everyday blackwall use, a sport-oriented series, or a more distinctive whitewall, redline, or raised white letter presentation where available.
Rim-width compatibility is also worth reviewing, especially on 16-inch, 17-inch, and 18-inch applications. Product details such as load capacity and tire weight can help separate one option from another, but those comparisons only matter after the correct size is established. A tire that suits the car’s current wheels and intended use is the right place to begin.
What sidewall styles are available for 2009 Chevrolet Cobalt tires?
Sidewall style depends on size, but the 2009 Chevrolet Cobalt is available with blackwall, wide whitewall, redline, and raised white letter options in certain fitments. The broadest appearance variety appears in the smaller sizes, while the larger 18-inch SS fitment stays focused on blackwall performance-oriented choices.
That makes appearance selection partly a size decision as well as a styling decision. Buyers keeping a 15-inch or 16-inch setup may have more room to pursue a custom or restoration-inspired look, while a 17-inch or 18-inch car will usually lean toward a more modern performance presentation. The sidewall treatment should still be chosen within the correct tire size first.
What brands offer tires for the 2009 Chevrolet Cobalt?
Tires for the 2009 Chevrolet Cobalt are available from BFGoodrich, Michelin, American Classic, Vredestein, and Nitto, depending on size. BFGoodrich appears across much of the size range, while other brands show up in more specific fitments or styling niches such as whitewall or specialty radial offerings.
Brand choice should come after confirming the correct size and wheel diameter. Once that is settled, compare each brand’s available series, sidewall style, rim-width range, and any stated load details that matter for the car’s setup. A 15-inch commuter-oriented Cobalt and an 18-inch SS naturally lead to very different brand-and-series comparisons.
Restoration & Appearance
Which tire should I choose for a period-style 2009 Chevrolet Cobalt?
A period-style choice for a 2009 Chevrolet Cobalt starts with keeping the correct tire size for the exact trim and wheel diameter. Once that is established, the available sidewall treatment becomes the main appearance decision, with certain 15-inch, 16-inch, and 17-inch sizes offering wide whitewall, redline, or raised white letter options alongside standard blackwall radials.
The right visual direction depends on whether the car is being preserved in a stock-like late-2000s look or given a more personalized presentation. Because appearance packages and dealer-level changes can complicate originality on newer collector cars, buyers focused on exact restoration detail should compare the car against factory literature or marque-specific references before choosing a specialty sidewall.
Does correct tire fitment matter for a 2009 Chevrolet Cobalt restoration?
Correct tire fitment matters on a 2009 Chevrolet Cobalt restoration because the model used multiple wheel diameters and noticeably different tire profiles across its trim range. A 15-inch LS-style setup, a 17-inch Sport Package arrangement, and an 18-inch SS fitment create very different visual proportions even before brand or sidewall style enters the decision.
Using the proper size helps the car sit and present the way that trim was intended to look. It also keeps the restoration from being undermined by a tire that appears out of scale for the wheel package. Before final selection, confirm that the car still carries the intended wheels rather than replacements added sometime after its original sale.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2009 Chevrolet Cobalt?
Yes. Modifications can affect tire fitment on a 2009 Chevrolet Cobalt, especially if the car has aftermarket wheels, suspension changes, lowering components, or body alterations. Those changes can influence wheel width, offset, steering travel, and clearance even when the tire size on paper seems close to the original trim-based fitment.
A Cobalt with replacement wheels should be checked at the car rather than judged by trim name alone. Confirm the actual wheel diameter and width, then look for clearance at full steering lock and through suspension movement. That step matters most on 17-inch and 18-inch combinations, where lower-profile tires leave less room for fitment errors.
What should I inspect before driving a 2009 Chevrolet Cobalt on new tires?
Before driving a 2009 Chevrolet Cobalt on new tires, inspect basic installation and condition items such as correct tire size, proper inflation, secure lug hardware, and visible clearance around the fenders and suspension. It is also smart to look for any rubbing points, sidewall contact, or uneven seating that could indicate a wheel or fitment problem.
A short low-speed test drive can reveal pull, vibration, or interference before the car is used more seriously. Rechecking inflation after the first drive is worthwhile, especially on a car that may have sat for a long period. Any uncertainty about wheel compatibility or tire-to-body clearance should be addressed before regular road use.
How often should tires on a 2009 Chevrolet Cobalt be inspected?
Tires on a 2009 Chevrolet Cobalt should be inspected regularly, not just when tread looks worn. A quick visual check before routine driving is sensible, and a more deliberate inspection at service intervals helps catch cracking, cuts, punctures, uneven wear, bulges, and pressure loss before they become larger problems.
That routine matters even more on a low-mileage Cobalt that spends time parked, because age and storage can affect a tire long before tread is used up. Air pressure, sidewall condition, and wear pattern should all be reviewed together. On cars with sport packages or larger wheel setups, staying ahead of alignment and suspension issues is especially important.
