Ed, you still have shakes?
I had shake at I think 60-70 mph and now after re-balance, I have shake at 50-60 mph. I found out the shop I was going to, their hunter machine can't do a full balance because they don't have the "latest" model.
Pepboys is just now upgrading all their wheel balancers to the top of the line Coats, but all the stores around me don't have it, only the one in South Side of Chicago (south Cicero).
So I called Just Tires, and there is one shop that can do it -- Norridge! They not only have the latest Coats machine but also the latest Hunter machine. This is pretty rare as most shops just have one or the other, as both top line models have "road force" measurements and diagnostic.
He said they can also do truck and commercial truck wheel balancing so 24" are easy.
It's $19.95/each wheel for dynamic balancing (not static!) and $95/hour for road force measurement/diagnostics.
He said I'll have no shake for sure since the wheels are perfect (I had 0 shake with Pirelli's) and that he'll run the wheels on both his machines to be 100% sure.
I'll have to put them in my FX and put on my winter's, as they won't touch spacers/adapters.
The good news for people going into 24's, is that they are becoming popular with SUV's (Escalades, Hummers, etc...) that the people I've talked to in the industry are saying, eventually all the new wheel balancers will easily handle 24's, once the stores upgrade their machines.
So right now, it's just a matter of time to find the shops that have the right machines.
This also lead me to find out why so many people have shakes with the FX, not only are our FX's sensitive, most tires shops can balance 22's, but not properly. They are only equipped to properly balance up to 20's, but the 22's will go on there but won't get the right balance from what I'm told.
Some might even get a static balance vs. a dynamic balance.
These new machines, the shop owner of Norridge says he tests using a rolling pin and also sonar! Then lasers are used to place the weights exactly where they need to be.
I'll report back when I have a chance to do all this.
