Expert Buying Guide for 2008 GMC Yukon
For your 2008 GMC Yukon, the 6x139.7 bolt pattern is shared across 1992–2025 models, offering broad wheel compatibility. Critical: the 78.1mm center bore must be matched exactly; aftermarket wheels with larger bores require hub-centric rings to prevent vibration and hub damage. Offset must stay within 20–30mm; deviating risks rubbing or poor handling. Always use 14x1.5 lug nuts with correct seat type—factory wheels use cone seats; aftermarket may require ball or conical. Improper seating can cause wheel loss. Verify thread pitch and seat before installation.
