What backspacing is needed on a 2001 Chevy Blazer?

There's no single "backspacing" for a 2001 Chevy Blazer. The correct backspacing depends entirely on the wheel size and tire size you plan to use. Using the wrong backspacing can lead to rubbing on the suspension, steering components, or body.

To determine the correct backspacing, you need to:

1. Know your wheel size: This includes diameter and width (e.g., 15x7, 16x8).

2. Know your tire size: (e.g., 235/75R15, 265/70R16).

3. Check for clearance: This is the most important step. You'll need to measure the space available between the tire and the suspension, steering components, and body of your Blazer. This often requires physically measuring with the tire and wheel installed, or using online resources and forums specific to Blazer owners who have done similar modifications. Many online forums dedicated to Chevy Blazers offer information on wheel and tire combinations.

Without knowing your wheel and tire choice, I cannot give you a backspacing recommendation. Incorrect backspacing can lead to serious safety hazards. Consult a tire professional or experienced Blazer owner for personalized advice.
