For the tire item above, Nokian snow tires are going to wear very fast if you are driving them above 40 deg outside as they are not meant for those temps at all. Also for the tire wear/camber comment, the car from the factory does not run excessive camber. If it is lowered, it will run more and if desired you can correct with adjustable control arms, but unless you are crazy low, even that amount of camber is not excessive even for the street. More likely the bad upper control arms were causing the outside wear on the tire by allowing it to be misaligned more.
