That depends on where you live and how much driving you do, even if you have snow tires in certain situations you're still going to need to put chains on. As for snow tires unless you live in an area that has consistent ice you would be fine with stud less snow tires instead of studded tires.
If you have questions about the correct tires for your vehicle give us a call at 541-791-2886
