Wider tires on 2022 Yukon XL Denali

[crankin]

Hi all,

I've searched this forum a few times and couldn't find myself an actual answer and real world experience.
I have a 2022 Yukon XL Denali 6.2L with magnetic suspension
has 275/60R20 from stock now.
I have decided to go with the Michelin Defender tires but my dilemma is I want to upsize the tire.
I don't want to modify the inner wells or rub when full cut.
the 275/60R20 is equivalent to 33" tall x 10.8" wide.
I've read people using 305/50R20 which gets me the width but loose on the height (32" tall x 12" wide)
Can anyone comment what size they would suggest?
Looking for something to give the wider stance appearance also don't want to void warranty or cause the dealer to be painful.

Thanks In advance !

I can confirm for you that the 305/50x20 Michelin Defender tire will fit on your truck without rubbing. And, yes, if you choose to do this, you will need a tune to get your speedometer synched to the new tire diameter.

Can I fit a 305/55R20 with no modifications ?
