Just picked up a 2021 K5 EX awd and realized it didn't come with a spare tire. I'm thinking of adding one, but I've heard that awd systems can get messed up if the spare doesn't match the rolling diameter of the stock tires.
Do I really need to go full size to avoid damaging the drivetrain, or is a donut okay for short term use? Would appreciate some insight before I go hunting for the right setup.
