You should know that would depend entirely on the tire chosen. Stock size, not chance to rub, 34" like I have, you wouldn't be able to drive a stock lr4. So, some care will be needed in choosing a tire and brand as some like BFG run a little small which can actually help such as when choosing the standard 265/65-18.
It is my 'guess' that size will work but people for some reason trying to use wider sections like the 285/60-18 could run into trouble on a stock vehicle. A size like 285/65-18 will definitely rub while a tallish tire 265/70-18 may still work due to being less wide at the tread.
