This topic reminds me of a post on some other car forum where a guy wondered why his Lexus IS300 spun out and lost control in the wet, hitting a tree, after he had Armor All'd his tires... the whole tire. He thought the sidewalls looked so good all wet and shiny he decided to grease up the tread too.
EDIT: Found the thread
HERE on a Lexus IS forum.
Sorry for the

but it's too funny.
