i have a 2020 Yukon XL Denali and I have 20" wheels all around. I am about to install the Brembo performance front brakes that will not allow for the 18" spare tire to be used up front. If you have a front tire flat, you have to remove a rear tire, install the spare in the rear, then install the 20" rear tire up front. I'd really like to just put a used 20" wheel with a beater tire back there and call it good. Anyone have this problem and will my solution work?
