Yeah, the musical score during that part was the big savior. I love it, it just made it hilarious despite the tire tracks. But I like it a tad better afterward, when they're going over Grady's sunny disposition, and all the graboids suddenly swarming towards them.
I just wonder, though...that graboid wasn't about to transform yet. And the truck being dragged had to make a lot of noise...so why didn't it stop and turn and attack them? Especially after they hit the rock...it kept on going. And somehow I don't think they were loud enough to scare it.
