I bought my first truck, 2019 ram 1500 bighorn. The stock tires are 18” and the aluminum (ugly) wheels are a + 19mm offset. I desperately want to change out the rims but have no idea what I’m doing. All the rims I like are not close to a 19mm offset. I just want nicer rims but have no idea what I’m doing and what I’m supposed to be looking for. How does this work? Do I need new tires to fit new rims? Are there nice looking rims somewhere with a +19mm offset? I’m not a car person so you’ll have to dumb it down for me. Please help.
