in have a crazy chance on brand new nitto grapplers 285/75 16 will they rub i do not have a lift. truck is sittin stock 2004 silverado 4x4 will i need to turn up my torshin bars?? please and thank you

 

on the oem wheels, I ran 285/75/16 buckshot maxxis on my '03 z71. didn't rub and didn't have to turn up the bars. But, it's hard to say if you'll need to turn up your bars or not without knowing what setting they are at now. my truck seemed to sit up a little bit higher than my buddies Z, so can't say for sure if the previous owner (I was second owner) had them turned up already or not. my torsion bar key bolts had about an 1/2" to 3/4" of thread left before the head of the bolt bottomed out on the key.
Hope this helps
