Ion Type 143 6x139.7 20x9+18 Matte Black Wheels for the 2021 GMC Yukon Denali

The 20x9 +18 offset on a 2021 GMC Yukon Denali will sit near stock positioning with a modest outward push compared to factory wheels on this platform. This moderate offset and 9-inch width support a square tire setup without requiring suspension modifications, though fender roll may be necessary if running aggressive low-profile compounds or after lowering. For a raised stance like shown, tire stretch is not recommended; maintain proper sidewall height to ensure ride quality and speedometer accuracy on the Yukon's larger frame.
