It will fit fine, I'm sure....being around 31" tall. Offset might be worth looking at, just in case though. BUT, 18" wheels may look different on these trucks. Personal taste is the main thing, but I will say that I don't see a lot of this era of truck on much bigger than 16" rims.

I've had 32x11.5r15 and 33x12.5r15 on stock height 4x4 blazers. You may have a touch of rubbing on the 33's.
