I would consider a couple of things. First, look at the specifications of the rims and see what they are rated for. Secondly, consider your intended use. If you off road you need side wall height and flexibility when going over rough sections. If you camp on beaches you need to look at air down capabilities.
IMO, these reduced height rims and tires are made for the highway. If used off road you run the risk of damage to the rims when encountering get obstruction.
Finally, I'd look at the tire ratings. Bottomline, depends on use.
