I've got the 97x Saab... the stock tire size is a 255/55/18 ... I'm thinking of buying a set of snow tires for next year in 265 60 18 ... it comes up as 1.5" taller then stock overall ... or .75" taller on each sidewall... that'll fit right? Was looking to see what might be just a bit taller so I can get a bit more ground clearance when pushing thru snow...
