    I take the hubcaps off too, and hide them in the trunk. The technicians will snoop around (looking for the suspension override) and install them, as a "favor." I don't go to garages any more...

    Re: The official Whitewall thread

    Well, unfortunately 3 of the 4 tires I got are duds. Hence the wobble. Once they got atarted, I was invited back to watch them balance and it was obvious what was the issue is. Looks like I might be switching to Diamondbacks. Kudos to the techs at Discount Tire who threw every trick in the book at them, but when the tires themselves have a warped sense of humor, they can't perform miracles. Took it up to 55 - 65 and the steering wheel was going nuts! That's with the best two tires on the front! Dang!

    We just got some adapters to use at work if we want to do a lug centric balance. Nobody has used them yet and I don't think anybody wants to. Ill have to test them out and see if they produce different numbers than the hub centric way.

    I don't know why you would want to. Wheels are hub centric to the car, that is the way they should be mounted on the balancer, too.

    Well, I think what 69Chateau said in post 192 makes sense. I havent seen any problems with hub centric balancing but it would be neat to see if any of the older steelies balance differently between the two methods.

    I had similar problem with my car. The front tires were very old and were causing this kind of wobble from 25 to 44 mph. Once they were changed for new ones, wobbling ceased. Curiously, if those warped tires were mounted on the rear axle, they caused just a slight shimmy. Maybe it was due to worn tie rod ends.

    Re: The official Whitewall thread

    Here is an excerpt from Coker Tires FAQ page:

    "What is lug centric balancing & do you recommend it?
    Lug centric balancing simply means the wheel is affixed to the balancer by an adapter that goes through lug holes, not through the center hole of the rim. Unlike aluminum wheels, which usually have a drilled and almost perfect center hole placement, steel wheel’s center holes are stamped. This frequently causes the center hole to actually be slightly off-center. If the center hole is used to mount steel wheels to the balancer, the balance will be inaccurate and the tire will not perform at its best. Your wheel and tire ride on the studs, so you want the assembly to be balanced as it rides on the car. Yes, we recommend lug centric balancing to obtain the most accurate balance & best ride for your vehicle."

    Re: The official Whitewall thread

    The problem with that statement is that the wheels are mounted to the CAR hub centric, not lug centric. Your wheels and tire do not "ride on the lugs" like they say, they ride on the hubs of the rotors and axles. The lugs hold the wheels on the car.

    But the steel rims have a countersink in each hole that "seat" with the acorn portion of the lug nuts. Thus centering the rim at each lug bolt.

    If it was hub centric, then there wouldn't be a countersink within the steel rim and the rim side of the lug nut would be flat and/or have a washer that presses against the rim.

    I have a pair of tires I just put on my car and it shakey at 50 mph or so, annoying as heck, they have checked balance after, still bad. Something isn't right. I knew I should have got the V-rated tires.... My last set of V-rated tires had almost no weights to balance out.

    The wheel hub is always centered to the wheel studs. The holes in the rim, for the studs, are drilled in a specific pattern to match the orientation of the studs on the hub assembly. If the center of the rim was off center, the rim would be off balance in correlation to the hub assembly. Therefore, lug-centric balancing would produce a more accurate balance of the wheel.

    What tire manufacturer provided you tires that balanced but still caused the shaking? This is exactly what I'm experiencing. When watching the tires spin, you can see them wobble and shimmy right on the balancer. And that's after they've been lug-centric balanced according to the machine. To me, this means the tire has imperfections that cannot be balanced away.

    This is what I am running on my 1991 Brougham. I assume your 1984 Deville runs the same size 225/75/R15's. Mine have about 4k miles on them now, they are quiet and ride nice. Very good tires in the rain as well, but our cars have oustanding traction for a RWD vehicle though.

    Friend of mine is running the same tire on his 2004 2wd Toyota Tacoma truck, they have over 20k miles on them. His truck is pretty quiet and rides dead smooth at 80mph, and the tires still have 2/3 of the tread on them.
    I have the "XL" version (extra load) for the hearses. They work very well.

    If the center of the wheel opening was off center, you wouldn't be able to get the wheel on the car.

    Let's get this thread back on topic, please.

    More whitewalls.
