I bought a new 2013 Silverado Crew Cab 4X4 Z71. Love it as much as I have all my past Chevys... Here's the thing. I want to put some nice summer wheels on. I can get a great deal on some 305/35R24 with a 25mm offset and these will replace the stock 265/65-18. I'm reading that I can go up a 35 without leveling.. I'm a little skeptical but that's why I'm here. I'm ok with the leveling kit, but why do it if I don't need to. I'm just wondering if I need to order the leveling kit before my rims get shipped next week. All help and information available is greatly appreciated.

 

24s and street tires on a 4x4? And no not on the 07+ can you run 35s without a levelin kit. You barely can run 35s with a 3" lk on stock wheels only. And I want to say that as long as you keep a + offset you should be fine with that size and no levelin kit. That tire is a 32x12x24 so you should be fine. May rub a tad just trim some plastic.

 

I got the 24's on and have very little rub on them
