I run HB tires & rims on occasion. They look good if you like big & flashy but they kill low end power & you'll definately need a high torque servo (150+). Run them on a tight on road track if you want a good laugh. I'm not trying to knock them, I still run them when I want something different or I want the ground clearance. Just be sure to take a few small jumps 1st. They REALLY affect the way the truck handles in the air.
