Rim and tire sizes
 

I have a 2011 silverado and I'm planning on putting a 7.5 rough country lift on it and I was just wondering would 20"x10 -24 offset with 35x12.50 federal couragia tires fit right without any cutting or rubing?

They will "fit" but it's gonna need a lot of trimmin. The kit pushes the tires out, and with the -24 offset they'll be pushed out more so it'll rub more

Would they have to trim the actually fender or just the inside? And would it make my truck look bad?

I also have a 2inch leveling kit already on it... I'm running 33x12.50R18 now but stock rims

The 7.5" rcx kit is their 5" kit with a 2.5" levelin kit on top of if. I'm pretty sure with a -24 offset on a 20x10 rim with 35x12.5 tires they'll rub metal, but maybe not. But I'm pretty positive they will

What if I put on a 3 inch zone body lift... Cause I have seen trucks run 37s with a 7.5 rcx and the zone lift

And what if I bought The rims with a positive 10 offset

With a 3" body on top you should be good with the rim and tire setup you want
