2009 Chevy Cobalt Factory Tire Specifications
The 2009 Chevrolet Cobalt comes equipped with exact factory tire dimensions that ensure optimal performance and safety. Understanding these original equipment manufacturer specifications helps maintain proper vehicle handling characteristics and prevents potential drivetrain issues.
Standard Tire Size Options
Our research reveals that 2009 Chevy Cobalt models use several tire size configurations depending on the trim level and package options. Base model Cobalts feature P195/60R15 tires as the primary factory specification. Sport and SS variants receive larger P205/55R16 tires for enhanced performance capabilities.
| Trim Level | Tire Size | Application |
|---|---|---|
| Base/LS | P195/60R15 | Standard equipment |
| LT/Sport | P205/55R16 | Performance package |
| SS | P205/55R16 | High performance variant |
Load index ratings for these factory specifications range from 87 to 91 depending on the exact tire size. Speed ratings typically fall within the S to H categories for standard applications.
Rim Diameter and Width Requirements
Factory wheel specifications for the 2009 Cobalt correspond directly to the approved tire sizes. Fifteen inch wheels accommodate the P195/60R15 configuration with a standard width of 6 inches. Sixteen inch wheels support the P205/55R16 setup using a 6.5 inch width measurement.
Bolt pattern remains consistent across all 2009 Cobalt models at 5x110mm spacing. Offset measurements typically range between +41mm to +45mm depending on the exact wheel design and trim level requirements.
Hub bore diameter measures 65.1mm for proper wheel centering on the vehicle hub assembly. These specifications ensure proper fitment and maintain the vehicle’s intended suspension geometry for optimal handling performance.
Understanding Tire Size Numbers for Your Cobalt
Reading tire size numbers becomes straightforward once you understand the standardized format. We’ll break down each component of the tire sizing system to help you make informed decisions about your 2009 Cobalt’s tires.
Decoding the Tire Size Format
Tire sizes follow a exact pattern: Tire Width / Aspect Ratio R Rim Size. The P195/60R15 tires on the Cobalt LS model demonstrate this format perfectly, where each number serves a distinct purpose.
Tire Width appears as the first number and measures the tire’s width in millimeters from sidewall to sidewall. The 195 in P195/60R15 indicates a 195-millimeter width, while the 205 in P205/55R16 represents a 205-millimeter width found on LT models.
Aspect Ratio follows the width number and expresses the sidewall height as a percentage of the tire width. A 60 aspect ratio means the sidewall height equals 60% of the tire’s width, creating a taller sidewall profile.
Wheel Size appears after the “R” designation and indicates the wheel diameter in inches. Your Cobalt accommodates 15-inch, 16-inch, or 17-inch wheels depending on the trim level and package selection.
What Each Number Means for Performance
Each tire dimension directly impacts your Cobalt’s driving characteristics and performance capabilities. Lower aspect ratios like the 50 found in P205/50R17 Sport Package tires create shorter sidewalls that enhance handling precision and steering response.
Width variations between 195mm and 205mm affect contact patch size and grip levels. The wider 205mm tires on LT models provide increased traction compared to the 195mm base tires, particularly during cornering and acceleration.
Aspect ratio changes significantly influence ride quality and handling balance. The 65 aspect ratio on LS models (195/65R15) delivers a comfortable ride over rough surfaces, while the 50 aspect ratio on Sport Package wheels prioritizes responsive handling over comfort.
Wheel diameter increases from 15 to 17 inches reduce sidewall flex and improve steering precision. Larger wheels also accommodate performance brake upgrades but may transmit more road imperfections to the cabin.
OEM vs Aftermarket Tire Options
Your 2009 Chevy Cobalt’s tire selection extends beyond factory specifications to include many aftermarket alternatives. We explore both original equipment recommendations and compatible alternative sizes to help you make informed tire purchasing decisions.
Original Equipment Manufacturer Recommendations
Chevrolet equipped the 2009 Cobalt with exact tire sizes based on trim level configurations. The LS trim features 195/65R15 tires as standard equipment from the factory. LT trim models offer three distinct wheel and tire combinations depending on your selected package options.
Standard LT models use 195/60R15 tires mounted on 15-inch wheels for everyday driving performance. Upgraded LT configurations include 205/55R16 tires on 16-inch wheels for enhanced handling characteristics. Sport Package LT models receive 205/50R17 tires on 17-inch wheels to maximize cornering precision and road feedback.
These OEM specifications maintain optimal speedometer calibration and preserve manufacturer warranty coverage. Factory tire sizes ensure proper load carrying capacity and speed rating compatibility with your Cobalt’s suspension and braking systems.
Popular Alternative Tire Sizes
Aftermarket tire options provide flexibility while maintaining safety standards when properly matched to OEM specifications. We recommend selecting alternatives that match your original tire’s load index and speed rating for consistent performance.
Popular 15-inch alternatives for 195/65R15 factory tires include sizes with equivalent load carrying capacity and temperature resistance ratings. Drivers seeking 16-inch replacements for 205/55R16 OEM tires can choose from multiple brands offering identical dimensional specifications.
Performance oriented 17-inch alternatives to 205/50R17 factory tires expand selection while preserving handling characteristics. Tire professionals can verify compatibility between aftermarket options and your Cobalt’s exact requirements before installation.

Seasonal Tire Considerations
Selecting the appropriate tire type for your 2009 Chevy Cobalt depends on your local climate conditions and driving patterns. Different seasonal tire options provide varying levels of performance across weather conditions.
All-Season vs Summer Tires
All-season tires offer versatility for most driving conditions throughout the year and remain the popular choice among 2009 Cobalt owners. These tires provide moderate performance across various weather conditions without requiring seasonal changes. Summer tires deliver superior traction and handling in dry conditions, making them ideal for warmer climates. But, summer tires aren’t recommended for areas with frequent snow or ice conditions.
Performance characteristics differ significantly between these tire types for your Cobalt’s standard sizes (195/65R15, 195/60R15, 205/55R16, 205/50R17, and 225/40R18). All-season options maintain consistent grip in temperatures ranging from 45°F to 85°F, while summer tires excel in temperatures above 50°F but lose effectiveness in cold weather.
Winter Tire Recommendations
Winter tires become essential for areas with heavy snowfall or icy road conditions. These specialized tires provide enhanced grip and traction in cold weather conditions, ensuring safer driving for your 2009 Chevy Cobalt. Michelin, Continental, and Goodyear manufacture winter tire ranges that match your vehicle’s standard sizes.
Temperature performance distinguishes winter tires from other seasonal options, with optimal effectiveness below 45°F. Installation timing matters significantly – we recommend mounting winter tires when temperatures consistently drop below 45°F and removing them when spring temperatures exceed 50°F regularly. Always verify your vehicle’s doorjamb specifications or owner’s manual for precise tire size recommendations before purchasing winter tires for your 2009 Cobalt.
Tire Replacement Cost and Where to Buy
Replacement tire costs for your 2009 Chevy Cobalt typically range from $70 to $130 per tire for mid-range options across all factory sizes. Budget-conscious drivers can find quality tires starting around $50 each while premium performance tires may cost $150 or more per tire depending on the brand and exact features.
Several major retailers offer competitive pricing and professional installation services for Cobalt tire replacements. Goodyear Auto Service centers provide comprehensive tire services with warranty coverage and can source all factory-specified sizes for your trim level. Discount Tire locations offer extensive inventory selection and often feature promotional pricing on popular tire brands suitable for the Cobalt’s 15-inch 16-inch and 17-inch wheel configurations.
Big O Tires represents another reliable option for purchasing and installing tires with locations nationwide and expertise in matching the correct specifications for your exact Cobalt package. These retailers maintain inventory for the 195/60R15 205/55R16 195/65R15 and 205/50R17 sizes commonly found on different Cobalt trims.
Online tire retailers frequently offer lower prices compared to traditional brick-and-mortar stores though you’ll need to arrange separate installation services. Popular online platforms include Tire Rack Discount Tire Direct and Amazon which provide detailed tire specifications and customer reviews to help guide your selection process.
Local tire shops and automotive service centers often provide personalized service and competitive pricing especially when purchasing complete sets of four tires. These businesses typically offer installation mounting balancing and disposal of old tires as package deals.
| Retailer Type | Price Range Per Tire | Installation Available | Warranty Options |
|---|---|---|---|
| Goodyear Auto Service | $80-$140 | Yes | Tread life warranty |
