How it works
|
TRU-BALANCE products are a one of a kind, patented wheel centering system, which centers the wheel to the wheel stud rather than the hub pilot.

The problem lies in the design of the hub piloted wheels. |

The theory is that the hub pilots center the wheel. This is not so. The fact is gravity causes the weight of the wheel and tire to rest only on the upper one or two pilots, leaving a gap on the remaining pilots.(Figure A) This is evident by the rust marks left on older wheels where the hub pilots touched. This results in the wheel and hub not being on center with each other, thereby creating an egg shaped motion when rotated. This uneven motion causes rolling resistance. Even with proper balancing of a hub piloted “centered” wheel, you are still off center. When you are off center you can't get a smooth ride. The bottom line is, you can’t balance an egg. |

The TRU-BALANCE wheel centering products bypass the hub pilot and actually center the wheel to the wheel studs using the 12, 4 and 8 o’clock positions. (Figure B) Only 3 sleeves or pins are required to find true center. The center is maintained even as the wheels rotate as the pin/sleeve location is always maintained. Perfect centering of the wheel and tires ensures the driver of a smooth, balanced ride. NOTE: When using TRU-BALANCE products in conjunction with any of the ring type balancers , always use small hole and reem out to size. Using the larger hole on the ring balancers will cause them to drop down 1/6" and cause more vibration. |
