I recently acquired a set of 245/75R16 goodyear wranglers with only abour 5K kms on them and would like to put them on my 1991 pajero for winter/ fall offroad use. The overall tire height for these goodyears is about the same as the 31.5 inch (15 inch rims) all season street tires on it now. Are there rims out there with the mitsu 6 bolt pattern? ( I saw toyota rims on a pickup that at a quick glance seem like they would fit). Is the swap feasible and is there anything I should look out for? Are there reasonably priced wheel suppliers out there?

all advice gratefully accepted
