Tire and wheels for 96 sierra sle
 

I would like to put 33's on my truck. I'm lifting it 2in I'm wondering if that's enough to fit the tires I want

well also make sure your rear can handle it too

...and don't forget recalibrating the speedo, and adjusting your headlight.

Far too many people change the ride height of their trucks, and neglect the headlight correction, usually out of neglect or arrogance.

You'll be tall enough, but how wide a tire are you going with?
