I'm very new to modding trucks and was wondering what would be the biggest tires I can put on a 2017 RTL stock rims of 18" and would be lifted 2.5" front and 1.5" rear, (So far traxda has the highest available lift), Without any rubbing. I tried to just reasearch it but it sounds really complicated and I can't really get a straight answer. I want my truck to look more aggressive. Any help would be much appreciated. Thank you.
