I currently have a 1998 V70 T-5 (turbo 5 speed) and need snow tires for it. It has 195/60/R15 size all seasons..but I'm finding I'm not getting good traction on just wet pavement. I'm sure the snow will be an issue this winter in the Northeast!

Someone has a studded set of 4 on wheels from a 2003 S80..Gislaved Nord Frost 215/55/R16 used.. Can these be used on my V70..given that the wheels are included?? What would be the downside?
This whole set would be cheap! Any help would be great
