  • For 22-inch upgrades: 275/45R22 or 285/45R22 are recommended to preserve ride quality
  • Wheel spacers over 1.25 inches require extended wheel studs for safe fitment
  • Always verify hub-centric fit: aftermarket wheels must match 78.1 mm center bore or use hub-centric rings
  • Z71 models with factory lift require additional clearance check before fitting wheels wider than 9.5 inches

Load Index and Speed Rating Requirements

  • Minimum load index for Tahoe tires: 113 (standard load) or 116 (extra load) depending on trim and GVWR
  • Minimum speed rating: S (112 mph) for base models; T (118 mph) or H (130 mph) recommended for highway use
