I have some a-specs with the 235/40/18's. They tried to balance these with a static balance. They put weights on the back side of the wheel only. Below 55mph, its decent. Above, its like riding on a gravel road. The crazy thing is on a smooth road, you can't tell anything is wrong. If any imperfections are on the road, the steering wheel finds them all. My question is as much as I hate the looks of the sticky weights, won't this give it a much better balance or will it be so little its just not worth it and also, they did it on a 8.5 wheel and not a 8". Again, so little or a great difference. IMO, every little bit will make a difference but I'm coming to the experts here for some advise. Thanks!

You need a balance from a Hunter Road Force Balance machine.

What kind of suspension and tires?

A dynamic balance is the only way to get a perfect balance. If you go to a shop that has a Hunter Roadforce balancer and someone posted you can do a dynamic balance and get it to zero out and ride good. The key is put the weights as far out toward the inside/outside as you can. Also make sure that the machine has been calibrated recently. It only takes a few minutes but we do ours at work once a week to ensure balance quality.

Also have them check the roadforce on your tires. This basicaly checks the out of roundness of the tire under weight (1600 pounds I think). If it has a high roadforce it will give that "wagon" type feel but is usally at really low speeds and the smooth at mid speeds and comes back at higher speeds.

Had been going to a tire shop for 20 years and no problems until I tried to get the 245/45-17 S.4 balanced on chromed Acura wheels. They could not get the 65/75 MPH vibration corrected. Finally had it done on a Hunter Road Force machine, no more vibrations. Normally sticky weights are applied as close as possible to the spokes and weights are clamped on the outer rim area.

Having said that, if balancing were imperfect, you'd most certainly feel the vibration especially on a smooth road.
