2019 GMC Sierra SLT X31 lift and tires

[ghmallard]

I have a 2019 new body style sierra x31. Came factory with 275/60/20 all terrains. Im wanting to put 35/12.5/20's xcomp gladiators (mud tire) on this truck. Im getting a lot of you need this and that but might be sales pitch as well. Any help would be greatful. What size lift do I really need 4'' or 6"? Can I use my factory rims or do I have to buy aftermarket wells? I was told needed 8'' lift and will need aftermarket rims. If I need aftermarkets for the 12.5'' tires what width could I go with to keep factory rims

Did you ever get this done? I have a 2019 gmc x31 also and want a lift and wheel rim package done.
