2015 GMC Sierra Z71 - wanting a lift and tires

[Brandon W. Jones]

I just purchased this truck and Im planning putting a 3" or even a 4"suspension lift on it and Im needing to know whats the max size mud grip that I can put on it? It has stock 18″ x 8.5″ rims. (I'm considering the "Trail Grappler MudTerrain")

Welcome! I recommend that you research on this forum about leveling, lifts and tires. There is a great deal of information on these topics. Reading about others' successes and failures can save you a lot of time and money. Many of us want to raise our trucks and boost our tire sizes at one time or another. This is not a one size fits all modification and there are some potential drawbacks to consider. My research took me from wanting a 6" lift to now having a 1.5" level kit waiting to be installed! Mud grip tires are great for specific off-road uses but be sure to know the trade-offs for regular use. Keep us informed about your mods!

BDS 4 inch and Zone 4.5 inch lifts will allow you to use your stock 18's. (There is another brand as well but don't remember it) With an aggressive tread design 295/70/18 will probably be the largest tire you can fit without major rub.
