The 2008 Grand Prix comes in several trims, each with its own recommended tire size. Here’s a breakdown:

Why Tire Size Matters
Choosing the correct tire size is not just a matter of aesthetics. Here’s why it’s crucial:

Checking Your Tire Size
If you’re unsure about your current tire size, you can find it in several places:
