Hi!… I am new to this forum and I am not schooled on tire upgrades and what not… my current vehicle is a 2014 jeep wrangler unlimited sport.. The rims I have on there now are 17 x 8 1/2… The tires that are currently on there are 255/75R17…on the box The rims came in it says ET = -18 which I looked up I believe means the offset is 4.25… I will not be going off-road with this vehicle at all I am just “theming“ it… that being said..my question is can I put 285/70 tires on those rims and not have to get a lift or put spacers… I understand I might have to trim or take off that piece of plastic that’s just under the fender because of possible rubbing on that… I have been looking at different forums and I’m not sure if I will have to do something with the gears… I hope I’m asking this all the right way.. because if I have to do a lift or put spacers in or mess with the gears I won’t do it was just hoping I can put the larger tire on there and be done with it… any info would be great thanks for replying in advance! I attached a photo of the outside of the box the rims came in also
