I think they're missing a dimension, how annoying is something to replace. In particular for car tires this called out to me. Going to an auto shop is an all day adventure for me, whereas almost anything else can easily be ordered or picked up without too much hassle. Furniture is another category though where there's a non trivial investment required to replace it. Therefore, these should be more durable, even if they're not something we're otherwise attached to. You could also think about the consequences of something breaking, and the cost of the loss of use. E.g., for a car, if it breaks down you might run the risk of an accident, and while it's broken down you might not be able to commute to work, etc., whereas some things are relatively inconsequential when they break.
