Hello, I've got a set of GoodYear Viva Touring tires on all 4 wheels right now. There is only 6/32 left on the tread. What is the best type of year-round tires for this car that would also give good traction in rainy and the occasional icy (black ice) roads. here in the southeast it doesn't snow much, just occasionally, but there are patches on black ice in the early AM. Thanks for any info!
