My beautiful refurbished Corona wheels have become a problem.

They came back out of balance and rather than take them the 80 miles back to Alloy Wheel Repair Specialist (AWRS) I tried my favorite local tire store. The worst problem wheel turned out to not only be out of balance but out of round also. Then measured the others and all were out of round. The outside of all was good but the interior was 0.035" to .054" out of round as measured by a computer managed Hunter force balance system.

Discussed with AWRS and they said (on the phone) that their warranty was lifetime and that I should bring the wheels back.

I went through this on some Jaguar wheels and found a specification of 0.015" maximum run out.

Now the question:

I would really like to be able to hold them to a manufacturer specification. Does anyone have documentation for a run out specification for the Corona wheels? .
 
Should be less than a millimeter on a new wheel, at least that was the green book spec for 140's.

[Typically it should take you 20 or 30 wheels to build a straight set of 4 or 5 anymore.]

Thought the wheel and tire came back already balanced. What made you take it to the tire shop for more inspection?
 
The intent at $140 per wheel was to not only make them pretty but round also.

One mm is 0.03937" so unless someone has a more definitive published specification the wheels may be within requirements.

When I drove it to the paint shop at least one of the wheel/tires was so out of balance the I couldn't drive over 50 mph.

Or jack up the car and put them on a front hub with 2 lug nuts and hold a pencil / stick up to the edge or in the bead and take a look for yourself.

Unless of course it's a particularly rare and or desirable wheel that is worth sending away for straightening and reconditioning.

Not that the Corona's are particularly rare or desirable wheels but that is the point . . . I sent them out for straightening and refinishing and 3 of the four now get a 'replace wheel' report from a Hunter road force balancing machine.

These wheels came off my 180k mile 245 so they are not virgins.

The question remains is 0.035 - 0.054 inch run out as measured on the Hunter machine within Volvo specifications? Another question: is the Hunter machine reading accurately?

I really don't want to debate these questions with the wheel folks 80 miles away from home.

Edit: Dropped the 'Volvo' in web searches and see modern aluminum wheel specifications are 0.3 mm (0.012"). Guess that provide enough of a discussion position. That is also close to the documented Jaguar specification of 0.015".

What became of the refinished wheels? Did you send them back for more massaging?
 
They are gathering dust as spare parts stacked in my garage just like a lot of things in yours. The restoration shop really did a great job on them. Straightened as best they could, stripped in a chemical bath, repainted the OEM grey and then the outside face lathe turned to bright aluminum and clear coated.

I considered using them as spares in my two Volvo's but I have already installed tires on the original spare wheels. The Bertone came with a full sized spare and butt cheeks. Really strange. Based on chassis number the Bertone was really near the end of the production run. NEL621 has the immediately previous chassis number on one of his cars and it has the space saver spare and no butt cheeks.

^ I would think that more of the Corona wheels would be in much better shape. It is a pretty solid wheel compared to other Volvo wheels.
 
I have been doing business with Voluparts in Atanta since I moved here in 1979 with only one Volvo at the time. My BFF Bill, the owner, is still there some 39 years later, Terry retired.

They had a rack of Coronas as well as racks of most every other wheel Volvo produced. The wheels had been checked and marked as to runout but probably only to two decimal places. Selected the less bent, best appearance ones and the wheel restoration store refurbished them as new and they did meet the 0.012" specification. Never was able to find a side to side runout specification which was the problem with the two that failed to meet the shop's requirements.

The wife got a new car and, as always, I got the hand-me-down which is 27 years younger than the 245. It has been sitting unloved for most of the Spring but your post this morning reminded me and I got it washed and cleaned up a bit. Took it for a 30 mile lunch and it still a nice running, nice looking car.

Think I will just keep it but need to build garage numbers 5 and 6.
