Rain tires

Talked to Goodyear this morning about rain tires.  It was a short conversation, they don't make rain tires for my car.  Avon, the other tire company do have rain tires, but you know how I feel about running Avons.
I do have a third choice, groove my own tires.  I wood need to purchase a tire grooving iron,  there not much money and I could use a old set of my Goodyears.  This just might work.
