Yeah man you will be fine. Those are roughly the same height and a lil more than 3/4" wider. Here is a link to a tire calculator so you can see how they compare.I have the PRG mini lift 2.5" leveling it, will a 285/65/18 tire fit on my stock wheel and not rub anywhere? I tried to search but it seems I get mixed results.
