I have a 2017 Ranger Z521c and I am looking to upgrade the stock 14" wheels that have 215/75R14 tires on them. Can I upgrade from the 14x6 wheels to 18x9 wheels and am I able to run wheels with up to -15mm offset without rubbing the fenders? I have run a tire calculator and have found tires that will be equal to the height of the stock tires on the 14" wheels now just not sure on how tall and wide I can go with aftermarket wheels.
