New tire help

[PMWZ71]

Time for new tires. I have a 2007 Tahoe z71 4wd and a 2012 Silverado z71 4wd. I just put 275/70r18 tire on the Silverado which has stock wheels and a 2" RC level. These tire have plenty of room with no rubbing. If I put the same level on the Tahoe will I be able to run the same tire with stock wheel offset? Side note Tahoe has 275/65r18 right now with no level (little larger then stock). Thanks for the input
