I was always taught that oil and grease would cause rubber to deteriorate. I don't know if that is true or not, but I was never allowed to use oil or grease on anything rubber, including tires. Also, dish soap, especially if mixed with water, can cause rust on the rims--remember, some of that soap and water mix is going to get trapped, almost permanently, inside the tire. I was only allowed to use Ru-Glide (sp?) which is a lubricant made especially for mounting tires. Must be something like the Europaste which Mitch mentions above. Note that the can Mitch shows in his picture says "rust inhibitor." Also, only "crank up the pressure" if the wheel is fastened down, like to the tire changer, or in a cage like is used for truck wheels.
I'm certainly an amateur at this, so make your own decisions; don't put too much stock in what I say. I'm only passing along what I was taught, right or wrong, by people who are smarter than me.
