1987 Buick Grand National Tire Size

When it comes to the 1987 Buick Grand National, tire size plays a crucial role in both performance and aesthetics. This classic muscle car, known for its turbocharged V6 engine and sleek design, demands the right tires to ensure it handles like the beast it is. If you’re an owner or a potential buyer, understanding the stock tire size is essential for maintaining its authenticity and performance.

Stock Tire Specifications

The stock tire size for the 1987 Buick Grand National is 215/65R15. This size strikes a balance between grip and comfort, providing a stable ride while allowing the vehicle to maintain its performance characteristics. Here’s a breakdown of what those numbers mean:

• 215: This is the tire’s width in millimeters. A width of 215 mm provides a good contact patch for traction.
• 65: This is the aspect ratio, which is the height of the sidewall as a percentage of the width. A 65% ratio means the sidewall height is 65% of the tire’s width, contributing to a comfortable ride.
• R15: This indicates that the tire is radial and fits on a 15-inch wheel. The 15-inch diameter is standard for many vehicles of this era.

Why Tire Size Matters

Choosing the right tire size is not just about looks; it directly affects handling, ride quality, and safety. Here’s why sticking to the stock size is important:

• Handling: The 215/65R15 size is designed to complement the Grand National’s suspension and weight distribution, ensuring optimal grip during acceleration and cornering.
• Ride Comfort: The aspect ratio contributes to how the car absorbs bumps. A taller sidewall (like the 65% ratio) helps in providing a smoother ride over rough surfaces.
• Speedometer Accuracy: Changing tire sizes can affect your speedometer’s accuracy. Sticking to the stock size keeps your readings correct, which is crucial for safe driving.

Aftermarket Options

If you’re considering aftermarket tires, there are a few things to keep in mind. While you can find tires that fit the same dimensions, not all tires are created equal. Here are some options to consider:

1. Performance Tires: If you’re looking for better grip and handling, consider a performance tire that fits the 215/65R15 size. Brands like Michelin and Goodyear offer high-performance options.
2. All-Season Tires: For those who drive their Grand National year-round, an all-season tire can provide versatility without sacrificing too much performance.
3. Classic Tires: If you’re restoring your Grand National to its original glory, look for tires that replicate the look and feel of the original equipment.
