The Avid Triad M4 Light Weight Wheel Nuts are possibly the lightest 10th scale wheel nuts on the market (0.3g/ea). The unique Triad design utilizes only three corners of the nut instead of 6 to give the nut its lighter weight. But don't think this takes away from the torque handling capabilities. With a quality wheel wrench you can crank these puppies down and the serrations will add the confidence you need for keeping them as you shred that PVC.
