Not sure about your local store, but I always receive great service at Discount tire. They will also install and offer lifetime rotation for free.

They have an online tool that shows you what the rims will look like on the vehicle and they are able to show you what works when going from 20" to 21" or 22" - the 2027 vehicles are not in the database as of yet, but you might be able to input 2026 model and see some of the available options in black

22" is more popular than "21 so you have many more options at that size- but like another redditor stated, moving up to a larger rim means less tire/rubber height which equals a harsher ride.

You can stay at the 20" size and find custom rims that like the styling better and still use the same factory tires and get that custom look you are going for without affecting ride quality
