2012 Chevy Traverse Factory Tire Size Specifications
The 2012 Chevy Traverse comes equipped with two distinct factory tire size specifications from General Motors. Standard trim levels feature 245/70R17 tires while higher trim packages use 255/65R18 configurations.
Standard Tire Size Configuration
Factory specifications for base and mid-level 2012 Traverse models include 245/70R17 tires. These tires measure 245 millimeters in width with a sidewall height representing 70% of the tire width. Load index ratings for this size typically range from 108 to 110 depending on the exact tire manufacturer.
Premium Trim Tire Specifications
Higher trim levels of the 2012 Traverse use 255/65R18 factory tire sizes. Width increases to 255 millimeters while the aspect ratio decreases to 65% for improved handling characteristics. These larger diameter wheels provide enhanced road contact and steering response compared to the 17-inch standard configuration.
Tire Pressure Requirements
Recommended tire pressure for both factory sizes remains consistent at 35 PSI for front and rear positions. Cold tire pressure readings provide the most accurate measurements when checking inflation levels. Maximum load capacity varies between tire sizes with 18-inch configurations supporting slightly higher weight limits.
| Specification | 245/70R17 | 255/65R18 |
|---|---|---|
| Width (mm) | 245 | 255 |
| Aspect Ratio | 70% | 65% |
| Wheel Diameter | 17 inches | 18 inches |
| Load Index | 108-110 | 109-111 |
| Recommended PSI | 35 | 35 |
Speed Rating Classifications
Both factory tire sizes for the 2012 Traverse typically feature T or H speed ratings. T-rated tires support maximum speeds up to 118 mph while H-rated options accommodate speeds reaching 130 mph. Speed ratings directly correlate with tire construction and heat dissipation capabilities during extended driving periods.
Understanding Tire Size Numbers and What They Mean
The alphanumeric codes on your 2012 Chevy Traverse tires contain critical information about dimensions, performance capabilities, and safety specifications. We’ll break down these tire markings to help you make informed decisions about replacements and upgrades.
Reading the Tire Sidewall
The tire sidewall displays a standardized format that reveals essential specifications for your 2012 Chevy Traverse. Taking the factory 245/70R17 tire as an example, each number and letter represents exact measurements and construction details.
245 indicates the tire width in millimeters from sidewall to sidewall. This measurement determines how much rubber contacts the road surface during normal driving conditions.
70 represents the aspect ratio as a percentage of the tire width. The sidewall height equals 70% of the 245mm width, creating a sidewall height of approximately 171.5mm.
R signifies radial construction, which describes how the internal cords run perpendicular to the direction of travel. Radial tires provide better fuel economy and handling characteristics compared to bias ply alternatives.
17 specifies the wheel diameter in inches that the tire fits. Your 2012 Traverse uses either 17-inch or 18-inch wheels depending on the trim level.
Additional markings include DOT codes for manufacturing information, maximum load ratings, and recommended inflation pressures. These sidewall details help ensure proper fitment and performance for your exact vehicle application.
Decoding Load Index and Speed Rating
Load index numbers appear immediately after the tire size designation and indicate the maximum weight each tire can safely support. The 2012 Chevy Traverse factory tires carry load indexes between 108 and 111, corresponding to exact weight capacities.
| Load Index | Maximum Load Capacity |
|---|---|
| 108 | 2,205 pounds |
| 109 | 2,271 pounds |
| 110 | 2,337 pounds |
| 111 | 2,403 pounds |
Speed ratings follow the load index and use letters to designate maximum safe operating speeds. Your Traverse typically comes with either T-rated or H-rated tires based on the trim package.
T-rated tires support continuous speeds up to 118 mph and work well for standard driving conditions. Most base trim 2012 Traverse models use T-rated tires as the factory specification.
H-rated tires accommodate speeds up to 130 mph and provide enhanced high-speed stability. Higher trim packages often include H-rated tires for improved performance characteristics.
Exceeding these ratings compromises tire integrity and vehicle safety. We recommend matching or exceeding the original equipment specifications when selecting replacement tires for your 2012 Chevy Traverse.
OEM Tire Options for the 2012 Traverse
General Motors equipped the 2012 Chevy Traverse with two distinct factory tire configurations to match different trim levels and performance requirements. These original equipment manufacturer specifications provide optimal balance between comfort, handling, and durability for this midsize SUV.
Standard 18-Inch Wheel Configuration
Standard 18-inch wheels came factory equipped on LT and LTZ trim levels of the 2012 Traverse. The 255/65R18 tire size represents the primary configuration for these higher trim packages.
Key specifications for the 255/65R18 configuration include:
- Width: 255 millimeters across the tread
- Aspect ratio: 65% sidewall height relative to width
- Load index: 109 to 111 rating capacity
- Speed rating: H-rated for speeds up to 130 mph
- Recommended pressure: 35 PSI cold inflation
Popular OEM tire brands for this configuration included Michelin Latitude Tour HP and Bridgestone Dueler H/L Alenza tires. These all-season radials delivered enhanced ride quality and improved handling characteristics compared to the smaller 17-inch setup.
Available 20-Inch Wheel Option
Limited availability 20-inch wheels appeared on select LTZ trim packages as an optional upgrade. The 255/55R20 tire size accommodated these larger diameter wheels while maintaining similar overall diameter.
Specifications for the 255/55R20 configuration feature:
- Width: 255 millimeters tread width
- Aspect ratio: 55% reduced sidewall height
- Load index: 107 to 109 rating capacity
- Speed rating: H-rated for 130 mph maximum
- Recommended pressure: 35 PSI cold inflation
OEM tire options for 20-inch wheels typically included Michelin Latitude Tour HP and Continental CrossContact LX Sport models. These lower profile tires enhanced cornering precision and visual appeal but resulted in firmer ride characteristics and increased road noise transmission.
Plus Sizing and Alternative Tire Sizes
Plus sizing options for your 2012 Chevy Traverse expand beyond the factory specifications while maintaining proper fitment and performance standards. Alternative tire configurations can enhance vehicle aesthetics and driving characteristics when properly selected.
Benefits of Plus Sizing
Plus sizing delivers improved handling performance through reduced sidewall flex during cornering maneuvers. Larger wheel diameters paired with lower profile tires create enhanced steering responsiveness and road feedback for drivers seeking sportier characteristics.
Enhanced braking performance occurs when plus sizing accommodates larger brake components and improves heat dissipation. Visual appeal increases significantly as larger wheels and lower profile tires create a more aggressive stance and contemporary appearance.
Reduced tire squirm during acceleration and deceleration provides better traction control on dry pavement surfaces. Corner stability improves through shorter sidewalls that resist deformation under lateral forces during turns.
Recommended Alternative Sizes
Plus one sizing from the standard 245/70R17 configuration upgrades to 255/65R18 dimensions while maintaining overall diameter within acceptable tolerances. This combination preserves speedometer accuracy and clearance specifications.
Plus two sizing options include 255/60R19 configurations that provide enhanced appearance while maintaining load capacity requirements. These dimensions offer reduced sidewall height for improved handling without compromising ride quality significantly.
Conservative plus sizing to 265/65R18 increases contact patch width for improved traction while staying within manufacturer load ratings. This size maintains proper clearance from suspension components and wheel wells during full steering lock positions.
Alternative width configurations like 235/65R18 reduce rolling resistance for improved fuel economy while maintaining adequate load capacity. These narrower profiles work effectively in winter conditions and provide cost savings through lower replacement tire prices.
| Plus Size Option | Wheel Diameter | Tire Width | Aspect Ratio | Overall Diameter Change |
|---|---|---|---|---|
| 255/65R18 | 18 inches | 255mm | 65% | +0.6 inches |
| 255/60R19 | 19 inches | 255mm | 60% | +0.3 inches |
| 265/65R18 | 18 inches | 265mm | 65% | +1.2 inches |
| 235/65R18 | 18 inches | 235mm | 65% | -0.2 inches |
