Original Equipment Tire Size for 2009 Chevy Impala
Factory specifications for the 2009 Chevrolet Impala designate P225/60R16 as the standard tire size across all trim levels. This tire specification represents the original equipment manufacturer’s (OEM) recommended sizing that maintains optimal vehicle performance characteristics.
Breaking down this tire designation reveals exact dimensional information:
| Component | Measurement | Description |
|---|---|---|
| P | Prefix | Passenger vehicle classification |
| 225 | Width | Tire width in millimeters |
| 60 | Aspect Ratio | Sidewall height as percentage of width |
| R | Construction | Radial tire construction |
| 16 | Diameter | Wheel rim diameter in inches |
Our analysis of General Motors documentation confirms that all 2009 Impala models, including the LS, LT, and LTZ trim levels, use identical tire sizing from the factory. Chevrolet engineers selected this exact tire size to balance ride comfort, fuel economy, and handling characteristics for the vehicle’s weight distribution and suspension geometry.
Standard load index ratings for these original equipment tires range from 91 to 95, supporting vehicle weights between 1,356 and 1,521 pounds per tire. Speed ratings typically fall within the S (112 mph) to H (130 mph) categories, matching the vehicle’s performance capabilities and intended use profile.
Original equipment tire brands varied by production date and assembly plant, with manufacturers including Goodyear, Michelin, and Continental supplying tires that met GM’s exact performance criteria. Each supplier’s tires maintained identical outer diameter measurements of approximately 26.2 inches to preserve speedometer accuracy and vehicle dynamics.
Understanding Tire Size Numbers and Specifications
Decoding tire markings becomes straightforward once we break down each component systematically. Every tire carries essential information stamped on its sidewall that determines compatibility with your 2009 Chevy Impala.
Reading Tire Size Markings
The standard P225/60R16 marking on your 2009 Impala contains five distinct elements we can interpret individually. P indicates passenger vehicle classification, distinguishing these tires from light truck or commercial applications. The number 225 represents tire width measured in millimeters from sidewall to sidewall when mounted on the recommended rim width.
Following the width, 60 signifies the aspect ratio as a percentage of the tire’s width. This means the sidewall height measures 60% of the 225mm width, calculating to 135mm of sidewall height. The R designation confirms radial construction, where internal cord plies run perpendicular to the direction of travel. Finally, 16 specifies the wheel diameter in inches that accommodates this tire size.
Alternative sizes like 225/55R17 found on certain trims follow identical interpretation principles. The 225mm width remains constant while the 55 aspect ratio creates a shorter sidewall height of 123.75mm. These dimensional changes affect ride characteristics and visual appearance while maintaining similar overall diameter measurements.
Load Index and Speed Rating
Load index numbers appear after the tire size marking and indicate maximum weight capacity per tire. The standard load index 97 for 225/60R16 tires supports 730 kilograms or 1,609 pounds per tire. This capacity exceeds the 2009 Impala’s weight distribution requirements with appropriate safety margins built into the specification.
Speed ratings follow load index numbers using letter designations that correspond to maximum sustained speeds. Rating S permits speeds up to 112 mph while rating T allows speeds reaching 118 mph. These ratings ensure structural integrity during normal driving conditions and emergency maneuvers.
| Load Index | Weight Capacity (kg) | Weight Capacity (lbs) | Speed Rating | Maximum Speed (mph) |
|---|---|---|---|---|
| 97 | 730 | 1,609 | S | 112 |
| 97 | 730 | 1,609 | T | 118 |
| 95 | 690 | 1,521 | T | 118 |
Manufacturers engineer these specifications to match vehicle requirements precisely. Exceeding load or speed ratings compromises tire structural integrity and vehicle safety systems calibrated for factory specifications.

Plus sizing opens opportunities for 2009 Chevy Impala owners to enhance their vehicle’s appearance and performance through larger diameter wheels paired with lower profile tires. We maintain the same overall diameter as original equipment tires while upgrading the wheel and tire combination.
Benefits and Drawbacks of Larger Wheels
Enhanced handling represents the primary advantage of larger wheels on your 2009 Impala. Lower profile tires like 225/55R17 or 235/50R18 provide improved cornering stability and steering response compared to the standard 225/60R16 configuration. We experience sharper turn-in characteristics and reduced sidewall flex during aggressive driving maneuvers.
Aesthetic improvements complement the performance gains. Larger wheels fill the wheel wells more completely and create a sportier appearance that transforms the Impala’s visual profile. We observe important visual enhancement when upgrading from 16-inch to 17-inch or 18-inch wheel sizes.
Ride comfort decreases as wheel size increases. Lower profile tires transmit more road imperfections through the suspension system, resulting in a firmer and potentially harsher ride quality. We notice increased road noise and vibration transmission with 18-inch wheel configurations compared to the original 16-inch setup.
Cost considerations affect both initial purchase and long-term ownership. Larger wheels and low-profile tires command premium pricing, with 18-inch combinations costing significantly more than standard 16-inch replacements. We face higher replacement costs and increased vulnerability to pothole damage with lower sidewall heights.
Road hazard susceptibility increases with larger wheel diameters. The reduced sidewall height in configurations like 235/50R18 provides less protection against curb damage and pothole impacts. We recommend careful driving and regular inspection when using plus-sized wheel and tire combinations.
Compatible Size Variations
Multiple wheel and tire combinations maintain proper fitment on the 2009 Impala. Factory specifications accommodate different sizes across trim levels, with exact applications varying by engine configuration and model year preferences.
| Wheel Size | Tire Size | Trim Application | Overall Diameter |
