What wheels fit a 2004 Trailblazer?

For a 2004 Trailblazer, you typically need a six-lug wheel with a 6x139.7 mm (6x5.5 in) bolt pattern, a center bore around 66.0 mm, and lug nuts sized for 14 mm studs. Wheels ranging from 15 to 18 inches in diameter can fit, provided the offset and width are appropriate to avoid rubbing or brake clearance issues. Always verify exact fit with the wheel manufacturer for your specific trim and brake setup.


Core fitment specs


Key dimensions you must match when selecting wheels for a 2004 Trailblazer.



  • Bolt pattern: 6x139.7 mm (6 on 5.5 inches)

  • Center bore: 66.0 mm

  • Lug nuts: 14 mm hex, typically with a 1.5 thread pitch; conical (60-degree) seat

  • Hub bore compatibility: aftermarket wheels may require hub-centric rings if the bore is larger than 66.0 mm


Keeping these specs in check ensures the wheel mounts correctly and centers properly on the hub.


Wheel sizes and offsets to consider


Ranges that commonly work on the 2004 Trailblazer, with attention to brake clearance and fender/quarter-panel clearance.



  • 15x7 inches, ET roughly 31–36

  • 16x7 inches, ET roughly 25–40

  • 17x7 inches, ET roughly 25–40

  • 18x7.5–8 inches, ET roughly 25–42


These ranges are general guidelines. The exact offset you need depends on wheel width, tire size, and whether any brake upgrades were performed. Wider wheels or larger tires may require a higher offset or minor fender modifications to avoid rubbing.


Cross-compatibility with related GM models


Other GM SUVs and trucks that share the same bolt pattern are commonly used to source aftermarket wheels. However, fitment can vary by brake package and trim.



  • GMC Envoy (similar generation and brakes)

  • Chevrolet TrailBlazer (same platform and brakes)

  • Related GM models with 6x139.7 mm bolt pattern


When using wheels from other models, confirm hub bore size, brake caliper clearance, and ABS sensor positioning. Hub rings or slight trimming may be required for a proper fit.


Practical fit and shopping checklist


Before purchasing wheels for a 2004 Trailblazer, run through these checks to avoid surprises at installation.



  • Confirm wheel bolt pattern and center bore exactly match or use hub-centric rings if needed

  • Verify brake caliper clearance and tire width to prevent rubbing at full turning radius

  • Check load rating and speed rating to match or exceed factory specifications

  • Measure backspacing or offset and compare with the vehicle’s existing setup to maintain proper track width

  • Ensure the wheel width and tire size won’t interfere with the ABS tone ring, sensors, or suspension components


With careful verification, aftermarket or OEM wheels can dramatically change the TrailBlazer’s look and performance without compromising safety or reliability.


Summary


The 2004 Trailblazer uses a 6x139.7 mm bolt pattern and a 66.0 mm center bore, accepting 15–18 inch wheels as long as the offset and width are suitable. Typical offsets range from the mid-20s to low 40s depending on wheel width, with 15x7 to 18x8 formats commonly seen on the market. Always verify fitment with the wheel manufacturer, and consider hub-centric rings and braking clearance to ensure proper, safe installation. If you’re unsure, consult a professional tire/wikel shop for a hands-on fit check.

How to confirm your vehicle's specific size
  • Check the driver's side door jamb: A sticker on the door frame will list the original tire size and the recommended inflation pressure. 
  • Look at the sidewall of your current tires: The tire itself will have its size printed on the sidewall, which is the most direct way to know what is currently on your vehicle.
