You'll have to figure out how wide those rims are. Minimum width rim for a 205/70/14 is 5".

A 215/70/14 would be 25.9" tall. That's probably going to cause you issues with tire height if everything is stock.

Thank you for the info. The rims are 6 inches wide so I think the 205/70's will work well. Yeah, I wasn't sure about the 215's...too tall. Thanks again for everyone's help here!
