Your post implies that the Michelins will be no different than the OEM Bridgestones. Nothing could be further from the truth.
I placed the 22" Michelin Defenders on my '16 SWB Denali at 12K miles even though there was loads of tread left on the Crapstones. The total ride has been transformed. GM would save themselves huge warranty costs if they would spec the Michelin Premier or Defender as the OEM tyres, as many owners would stop complaining of the awful ride and noise at subsequent service visits.
To any owners out there who hate the low speed lack of compliance, and who want to obtain better handling; better poor weather performance; less noise, etc; do yourselves a favour and replace the dreadful Bridgestones with either of the Michelins.
