Stock Samurai rims are 5.5" wide and take a 205/75R15 tire. Using my BFG TA/KO tires for reference, a 215 tire is commonly spec'd for 5.5-7" rim width, the 235/75R15 size calls for 6-7" rims and the 30x9.5" for a 6.5-8.5" rim width. Although 215's do fit without changes, expect larger tires to require a lift or some body modifications.

A lot of Zukers run wide(r) tires on supposedly too-narrow rims without problems, largely because the vehicle is so light. It all depends on where and how you drive. If you're on the interstate at high speed, or crawling along in the boondocks, your needs differ. "Airing down" for traction makes narrow rims more problematic, so caution with very low tire air pressure is appropriate.

Check with the manufacturer's published data (an internet search will usually turn it up) for your preferred tires and deviate from that using your very best judgment, considering your tolerance and skills for fixing stuff wherever it may happen to break. For example, can you re-seat a tire bead by yourself in the outback? You will get a lot of opinion on forums like these (e.g. it worked for me), but it seems most prudent to start with the published data and proceed from there.

Edit: I'm thinking that if you're willing to trim the front bumper a bit and pound the inner fender seams flat, you might be able to run 235's. True, they're spec'd for a 6" rim, but that's only a half-inch larger than stock. The wider tires still fit within the fender flares, and look a lot better (IMHO). I have the Petroworks 3/4" shackles (3/8" lift) which might get you the last little bit of clearance if you need it. Not being comfortable with mis-matched tires & rims, I went with 7" rims.

You needto check local laws, in some countries it is not legal to fit a non-approved tyre size to a rim.
