I have a 08 equinox that needs new tires. I have been out of work for a while and can't afford to buy winter tires but was looking at getting those all weather tires but can't find them my exact size. What else can I put on. I did notice on kijiji that there were some winter tires for sale for same vehicle but they were 215/70 r16 instead for the factory 235/65 r16. Can this be right.
