I currently reside in Indiana where winter is not too bad. But this is my first winter with 18in wheels and my p7000SS. I know P7000 is not the greatest tire made but I bought em since they were not that expensive, and they are supposdly be all season tires. Now I am at a point where I hardly have traction in any wet condition. Being a poor college student, I have option to replace two rear tires.getting winter tires is not an option for me. SO What would be my best choic? Get a new pair of tires if so what are some good year round tires in 18in??
