I am a factory authorized technician for Hunter equipment. The idea behind "RoadForce" is to see how round the tire/wheel assembly actually rolls with a load on it (simulated vehicle weight). You are correct that many cast wheels have little problem with low and high spots. Factory wheels are almost always better than any but the most expensive aftermarket wheels. The wheel is rarely a problem (unless it has taken a heavy blow), but the variation of sidewall stiffness in tires is pretty amazing. The most uniform tires get sorted out for use on new vehicles and the rest get sent to tire dealers. Sometimes there is enough variation in the wheel to forcematch and cancel out the variation in the tire and sometimes not.

I agree that for the most part truck suspensions are not as sensitive to the variation in sidewall stiffness, but some of the larger, more aggressive tires used on 4x4's have substantial uniformity problems. Many would be amazed at the difference in ride quality after being forcematched.

For those who would like more info on this process you can read about it at www.GSP9700.com . There is also a tab labeled Locate A GSP9700 to find a shop near you that has this equipment.

 

Never been to sea, the Hornet command I was with was Advisory, The nuts and bolt of that means that we played the bad guys to train the new guys air to air combat.

Not going the the carrier is one of my regrets after leaving the fighters, but it was not by my choice. The one time we were supposed to go to the boat Hurricane Katrina came and wrecked our plans. Hopefully I can go back to fighters and get some sea time under my belt.

 

you sound like a friend of mine. he was FDC for field artillery in the 82nd. Airborne for something like 8 years and has been to iraq twice and he has a constant ringing in his ears, he's 29 now. he said that he hears it all the time. he's a drill sergeant now so at least he shouldn't do any more damage to his ears.
