I'd like to hear from drivers that have used 4 season (mountain snowflake) tires like the Goodyear Assurance Weatherready or other brands. Here in Edmonton we don't get a huge amount of snow. In spring we can have 2 months of sunny dry pavement and then get a dump of snow that lasts a few days. Also on trips to the mountains there can be patches of snow. Not looking for high performance just decent traction. I have dedicated winters now but they aren't much better than all season tires on ice. I think replacing the tires every 2 1/2 to 3 years would be better that replacing 2 sets every 5 to 6 like I am now.
