I would agree with everyone Wallards is not the place to have other than stock tires mounted even then I question that hell my walmart won't even let me put tires other than what "the book" says I definately would go to a tire store such as discount, goodyear ect.. where I live there are a lot of hipsanics that have little shops that can do it also and very cheap so I would definately look around also what is the width of the rims? you can go to tirerack.com and it will tell you the reccomended rim width too for each tire size I looked at tire rack and the size is 205/50/17 but if you go with 40 series it you should go with 215 but I don't know for sure when I worked at a tire store the rule was if you dropped a series then you went up one tire size so in theory 215's should fit but I haven't seen the rims
