Pardon me, but I've been in a meeting and obviously missed the scented snow tires post...
 

It's not often that I am presented with a vehicular or technical subject with which I am unfamiliar so I am mystified by the concept of a scented tire.

Please fill me in.

Now that you're married, Jill is supposed to do that, per the contract.

She probably knows what they are but doesn't want to embarras me.
