I'm about to give up here...

when one dynamic balances one MUST/SHOULD place the weights as directed by the Computerized balancing machine at both the outermost and innermost postion on the wheel. That puts weights on the outside of the rim.....

To avoid putting the weights on the outside of the rim (one goal of mine), you must then FOOL the balancer by placing LOTS MORE weight as far to the outside on the inner side rim so it has the same affect as if it were mounted completely outboard. There comes the rub.... that can often amount to WAY MORE weight added to your wheel/tire assembly than is considered acceptable.. like 7 / 8 / 9 ounces and up to account for a 1.5+ ounce weight hooked to the outside of the rim.

These 7.5X 15" Trigos simply do not allow one to get far enough to the outer face of the rim from the back side.... to cut the FOOL THE MACHINE WEIGHT down to an acceptable amount. The 18 / 20 / 22 / 23" rims available today are constructed such that you can hide ALL of the weights on the inner side of the wheel while achieving a complete dynamic balance.

We went through this for 3 hours on the Hunter DSP9700 Vibration Control System (this gave us the match mounting data), and a Hunter DSP9000 Dynamic Balancer where we checked each wheel for weight load differential and roundness (well within acceptable standards).

Once the assemblies were match mounted, the 9700 was calling for 8+ ounces (THE BEST VALUE ACHIEVED ON ONE OF THE NEW BFG's) to acheive the same result of 1.5 ounces applied to the outer lip of the rim, an UNACCEPTABLE AMOUNT BY ANY STANDARDS.

The final result for the static balance after match mounting was 2.5 ounces on one and 2 ounces on the other assembly, located on the very center inside surface of the rim. A subsequent spin-up on the DSP9000 showed both assemblies in an acceptable range.

For more info on the 9700 and all that is going on here... you can visit:

The acid test, of course, will come when the recipient vehicle is put on the road.

Whew...... thats it on this topic for me....
