Welding wheel bolt pattern

This is more exploratory in nature at the moment. 

I have a set of 16×8 billet centerline wheels. They are from the 90s.

They are dual drilled four lug pattern. They have near perfect backspace. 

I WANT to put them on my 95 Silverado. Its 5×5 pattern. 

Is it safe to have the current holes welded up by someone and then have the correct pattern drilled? What would that do to the aluminum, and the ability to polish them?

Failing welding and drilling. Does anyone have the ability to make a set of.adapters that would go from my five lug pattern to use 6+ holes of the dual drilled four lug pattern?

Do i need to scratch this idea altogether and just be happy with truck rally wheels?

Can you use the wheels you have that don't really fit to trade / sell for ones that actually fit?

The adaptor route might be OK. Can that welding be done - yes. Should it be done - not yes IMO.

Is there enough meat in the center to drill the 5 on 5 lug pattern?  Is the mounting surface large enough?  

Any decent machine shop can do the work, finding one that is willing to do so would be more problematic.

Ill grab picture of the wheels shortly. Taking a break for a minute from scrubbing nicotine and filth out of an interior. When i go back downstairs ill grab one.

One can weld up holes.

One of the cars I used to race had peg drive wheels and the hubs had four holes approx. 3/4" in size. I had them carefully filled with weld and redrilled for bolt on wheels after checking them on a lathe with a dial indicator to confirm that there was no deviation from true as a result of localized heating. Raced on them for the next 10 years. 

having said that I also agree that finding some wheels that have the right bolt pattern is a better way to go.

So, its sounds like welding may be a bad idea.....

Id also worry about the amount of material left after drilling another pattern, honestly. I base this off od using a truck rally center cap as a guide for holes (the holes are larger in the cap than the wheel by about 1/4 inch or so.

Reason for this is that i really like the design of THIS wheel. Theres very few billet wheels in 16-17 in a 5x5 pattern. and the majority of them are a little too busy. 15s are ok, but the tire selection is very limited these days. And i have a set of  15x8 wheels that need tires that i already like. 

But i cant shake the idea of these wheels on my truck, with some fat by tall all seasons 

There are professional shops that do wheel repair and re-drilling all the time.  They TIG weld the holes up and drill new ones.

Possible?  Yes.

Expensive?  Yes.

I just had a thought: what about cragar style shank lug nuts and washers? Would that allow a simple redrill and maintain strength and wheel integrity enough for 1/2 ton truck stuff?

Weld and re-drill is common practice for many in the vintage/rare wheel hobby. There are several specialty shops that will perform the task, and on a wheel like this should be no sweat for them. I can dig around on a couple FB groups I am in and try to find names as I haven't needed this type of service myself, or I betcha Chandler may have some insight as well.

Please! Local to me would be better,  save on shipping. All the Google searches ive done have come up with nothing. 

I may be pissing in the wind financially though. Dunno....

Here is a list from a stance forum:

On that list, I personally have only dealt with VR Wheels, and only to purchase a set of wheels 10yrs ago, no custom services. I still see many good reviews on them. Unfortunately, they and many others I see recommended are out in California...

One outfit closer to you who I have seen mentioned several times, is Ehrlich Wheelworks. No personal experience, but maybe worth a call to discuss your specific application with them.

What about filling the holes, welding a plate over the center and drilling the hub and new bolt pattern through the new center?   Might be overkill but also stronger?  If you do it on the backside you can drill the correct hole to make them hub-centric and also get a little more neg offset

In reply to mister billet centerline:

Listen to jfryjfry. He said exactly what I was gonna say. 
 

but let me take it to another level and suggest finding someone with CNC ability to make you a billet version of the Chevy truck rally center cap that fits the centerline wheel. Because berkeley yeah, that's why!

just make sure the lug pattern is indexed to the valve stem hole such that the valve stem is at 6 o'clock with the bow tie upright and a lug at 12.

And while we're at it, can we cock-punch anyone who puts a lead weight on the lip of a billet wheel? Please?
