Formula V is NOT A TIRE SOFTENER. It's a TIRE RESTORER. 

Think of a tire like a sponge. Once you have used a sponge, when it dries out it gets hard and stiff. Wet it again, it is soft and pliable again. Formula V puts the petroleum based moisture back into the tires so they can CONTINUE TO RUN SOFT FOR THE LIFE OF THE TIRE.
