Yet another size question - Ridge Grappler

[zomby]

Hey all. Noob to the world here and want to clarify before I step into tires/lift.

Currently I am a bone stock 2025 Sierra 1500 AT4. Base rims/tires. I am planning to add the 1.75 leveling kit from Rough Country. After that I am getting new rims (18 vs the 20), and Ridge Grapplers for tire.

With just the 1.75 level kit, and an 18 rim. What size tire is the biggest I can go? I am ok if I need to do a mudflap delete or a teeny bit of trimming. Also ok if I need to add a spacer as long as it's not crazy.

Sorry if any of this is dumb.

Thanks

I can't tell you the tire size with 18's since I have 20's, but what I would suggest is to get a rim with a negative offset rather than running a wheel spacer. I got new rims with 0 offset and I have about an inch poke outside the fender, if that's what you're looking for.
Good luck!
