Back in the day, I recall we (S&S Tire) only had one tool we used for certain wheels that was NOT designed for utilizing the center bore, and those were (going off memory) 6*5.50”......for Nissan 4WD pickups and SUV’s and some Toyota pickups and SUV’s (note these were 4WD applications with manual locking hubs = larger than average center bore). Apparently any cone that could have been used for balancing was too small, or was not compatible at all.
Yep, the Hunter version you have the link to, or Haweka. That's why I wrote 99% earlier. Most people, unfortunately including at tire stores, don't know about their existence.
But technically at least the Haweka should be used with a cone at the back of the wheel, not the normal flat disc.
See that’s where I would argue otherwise. I run my weld wheels as a daily and on the track and have reached speeds up to 160 with no vibration issues.
Since we have brought up Hunter Engineering here, you may be aware of the fact that its Road Force Variation balancers have a Smart Weight setting.
It is there to get a close-enough balance while saving on wheel weights. Time and money for the tire store. And sure enough, most people are perfectly happy with their close-enough balance.
But if you have enjoyed really well balanced wheels, you wouldn't settle for close-enough. Or bent wheels studs, for that matter.
