Understanding Tire Size Numbers and Ratings
Understanding tire specifications becomes straightforward once we decode the alphanumeric sequence stamped on every tire sidewall. These numbers and letters contain crucial information about your 2015 Chevy Equinox’s tire capabilities and limitations.
Reading the Tire Sidewall
Tire sidewall markings follow a standardized format that tells us exactly what we’re looking at. The sequence starts with tire width measured in millimeters, followed by the aspect ratio as a percentage of the width. Next comes the construction type (typically “R” for radial), then the wheel diameter in inches.
For the 2015 Chevy Equinox’s 225/65R17 specification, the 225 represents the tire width of 225 millimeters. The 65 indicates the sidewall height equals 65% of the tire width. R signifies radial construction, while 17 denotes the wheel diameter in inches.
Additional markings include the load index and speed rating, which appear after the basic size information. DOT codes indicate manufacturing date and location. Maximum pressure ratings show the highest safe inflation level for that exact tire.
Load Index and Speed Rating
Load index numbers correspond to exact weight capacities that each tire can safely support. The standard load index of 102 for 2015 Chevy Equinox tires means each tire carries up to 1,874 pounds. This capacity ensures safe operation when the vehicle reaches its maximum loaded weight.
Speed ratings use letters to indicate maximum safe operating speeds under optimal conditions. H-rated tires handle speeds up to 130 mph, while V-rated versions support speeds up to 149 mph. Premium trim packages typically include V-rated tires for enhanced performance capabilities.
| Rating Type | 2015 Equinox Specification | Capacity/Speed |
|---|---|---|
| Load Index | 102 | 1,874 pounds per tire |
| Speed Rating H | Standard on most models | 130 mph maximum |
| Speed Rating V | Premium configurations | 149 mph maximum |
Exceeding these ratings compromises tire integrity and vehicle safety. Manufacturers engineer these specifications to match the Equinox’s performance characteristics and weight distribution. Replacement tires must meet or exceed the original equipment load index and speed rating requirements.

Maintenance Tips for Optimal Performance
Proper tire maintenance extends the lifespan of your 2015 Chevy Equinox tires while ensuring consistent performance across all driving conditions. Regular maintenance practices protect your investment and maintain the safety standards established by the factory specifications.
Rotation and Alignment
Rotating tires every 6,000 to 8,000 miles prevents uneven wear patterns that commonly develop on the Equinox’s front-wheel-drive configuration. Front tires typically wear faster due to steering, braking, and acceleration forces, making rotation essential for maximizing tread life across all four positions.
Following the forward cross pattern works best for the Equinox’s directional stability requirements. Move the front tires straight back to the rear positions, then cross the rear tires to the opposite front positions. This pattern accommodates the vehicle’s weight distribution and maintains proper traction characteristics.
Checking wheel alignment every 12,000 miles or when you notice steering pull prevents premature tire wear on your 225/65R17, 225/60R18, or 225/55R19 tires. Misalignment causes rapid edge wear that can reduce tire life by 30% to 50%, particularly affecting the outer edges of the tread pattern.
Professional alignment services typically cost $75 to $150 but save hundreds in premature tire replacement. Alignment specifications for the 2015 Equinox include precise camber, caster, and toe settings that maintain the load index rating of 102 across all tire positions.
Pressure Monitoring
Maintaining proper tire pressure optimizes fuel efficiency and ensures your tires operate within their designed load capacity of 1,874 pounds per tire. The 2015 Equinox’s tire pressure monitoring system alerts you when pressure drops below safe levels, but monthly manual checks provide better maintenance control.
Checking pressure when tires are cold gives the most accurate readings for your Equinox’s specifications. Temperature changes affect pressure by approximately 1 PSI for every 10-degree Fahrenheit variation, making seasonal adjustments necessary for consistent performance.
Standard pressure recommendations range from 32 to 35 PSI depending on your exact tire size and load conditions. The 225/65R17 configuration typically requires 33 PSI, while the 225/60R18 and 225/55R19 sizes operate optimally at 35 PSI for balanced wear patterns.
Underinflation by just 5 PSI reduces fuel economy by 2% to 3% and increases tire wear along the outer edges. Overinflation creates center wear patterns and reduces the contact patch, compromising the traction characteristics essential for the Equinox’s electronic stability systems.
Digital pressure gauges provide accuracy within 0.5 PSI and cost $15 to $30 for reliable long-term use. Checking pressure monthly and before long trips maintains the H-rated or V-rated speed capabilities while preserving the structural integrity of your radial construction tires.
