I would strongly consdier trying- NO Balance.

I run a set of 10*6 wellers ( steel wheels)   - i personally hand mounted each tyre- Aired them up- and put on car.

No vibration no shaking- no track issues- simply rolls fine up to 65mph ( dont know much past that)

anyhow

Just my thought. 

Just FYI. You might find this interesting, and maybe give you some info to toss out to shops that say it can't be done.

No one in town will balance them and I have called and asked dozens of places.  Not even specialists.  Not even "old-school" specialists. Nor race car shops.  

The conclusion is: If these wheels are to be used in the midwest.  They'll need to be modified.  And considering the wheels are on the heavy side, they are kinda worthless.  Its a shame since they look pretty good.

Obviously the wheels were balance-able in the 70's.  Times change.

The problem isn't the wheels, the problem is the place that is doing the balancing.
Go somewhere else.
I can think of some wheels that don't even have centre holes.

Isn't it amazing that Leyland would make - and sell - millions of wheels that can't be balanced....

I think you need to find a proper (old school) specialist.  I never (sic) had any issues with getting those wheels balanced when we had them on my Daughter's car..

Why not try asking Heritage (who sold you the wheels??) how you get them balanced....

Even the balancing machines that balance "lug-centric" need a 37mm opening in the center.  So, I figure I'll just have to put the wheels on a lathe.  And do the job myself; cutting out a 37mm center hole.

"back in the old days'... my uncle had a service station. The wheel balancer he had was a flying saucer-shaped thing that somehow clamped onto the rim and had a couple of concentric knobs to calcualte balance. The wheel was spun on the car by an electric motor with a small hard wheel on it that was pressed agais the tread surface of the tire. He would spin the wheel up to about highway speed and push and pull on the concentric knobs. I think they adjusted weights inside the flying saucer thing. When the wheel spun without vibration, it was in balance. He then read the scales on the knob shafts or pointers or something (I never did see what), they told him where and how much weight to add. Once the weights were added, he'd re-spin to verify balance.... I guess the indicators would end up at "zero" if the wheel weights were right.

In an old car repair book I have there are instructions for balancing wheels on the car

look for a place that does trailers. Maybe they can help you.

You can buy a cheap bubble balancer at Harbour Freight along with stick on wheel weights.

Just a note, they are not Rostyle wheels, they are Italian Firsat wheels. They were fitted to some Innocenti Minis and the Australian Leyland Mini S.

Will they fit on your hubs ?

The shop just needs to use a lug-centric adapter. If they don't know what that is, go somewhere else.

.that's a lot of weights on one side

I would tell you to balance them at home, but all of the balancing methods I know require a perfectly round and perfectly centered hole in the middle. If the machinist still can't get them perfectly circular, maybe consider going slightly larger to get them perfect and find a cap (or machine one) to fit.

A few months ago I bought some ROstyle steel wheels from Heritage Garage in California.   Soon I found out these wheels might be totally useles.  Only because no one would mount/balance tires on them because they don't have a circular center hole.  

So I paid local "british car experts" Quality Coaches here in the Twin Cities $100 to machine them round.  They are not round and are still way too small to fit onto the cone on a balancing machine.

Anyone have any experience getting these style of wheels balanced? Some people have mentioned "bubble balancing", but no one around here does that.
