Hello all, I have a 2013 5.7 Louisiana edition. I?ve owned it for over 3 years and although I love my truck, it?s time to knock the average off it.. so far I have a 3/1 ready lift & some smoked out tail lights. My 275/55R20?s are worn out and it?s finally time to go bigger. 90% sure I will be going with Ridge Grappler 35/12.5R20?s on my stock TSS rims (50+). I?m wanting them to stick out a inch or a little more so trying to figure out how big of a spacer to use. Thinking 1.25 will do the trick and not cause to many extra rubbing issues. Top it off with some bushwhacker flares and be excited to drive around again.. Any thoughts or advice are welcomed.. Already found many helpful info in here like the front fender/ skidplate tuck..
