Comprehensive Wheel Joint Study

We are now finishing what is to our knowledge the most comprehensive wheel joint study yet conducted. We were contracted to test 51 different combinations of wheels, studs and lug nuts to increase understanding of joint variables, guide tightening strategies, and reduce the potential for wheel-offs. The tests included:

  • Torque-Tension
  • Static Relaxation
  • Dynamic Relaxation
  • Effect of Paint Thickness
  • Slip Load

In total, we sensored over 2,100 studs for ultrasonic tension measurement and recorded over 6,600 rundowns. If you have design or production responsibility for wheels, drums, calipers, lug nuts or for verifying their safe assembly, give us a call so we can apply our experience to your needs. Please contact Dave Archer directly at 248 894-2295.
