Ok. I think your tire size now is something along the lines of 265/65/17. What you can do is go with 265/70/17 or 285/65/17 (check availability of size).

First option given is about an inch taller or so but is the same width. The second option is a little bit taller than stock, almost as tall as the first but a little wider.

both will fit with minor trimming to back of mudflap. No biggie.
