Replacing a tire on a wide 5 wheel, adaptor needed?

Yes, your tire shop will need an adaptor to spin balance the new tire.  Ask the tire shop if they have one in order to spin balance the new tire.  If they don't know what you are talking about, find another tire shop.

Some guys buy the adaptor for themselves so they can loan it to the tire shop for their tires.  But, you should be able to find a tire shop with one.

And, just because they have the adaptor doesn't mean they know what they're doing.  I remember the time I was having Bridgestone Potenzas mounted at a Firestone store.  They were taking forever to balance the tires and I finally stuck my nose into it.  Well, they had the adaptor but were having a heck-of-a-time trying to balance with the only two lugs (out of 5) they could find.

After speaking to the manager, we agreed that Firestone would pay another tire shop that knew how to balance wide-5s for me to go to.  Still, had I not stuck my nose in it I think they were at about the point of giving up and I was going to get the spyder back with new, expensive, unbalanced tires.

Thanks RS-60 mark!

I found this adaptor and I think it's what I need... I'm guessing I can remove the lug bolts out of the middle, move them to the outside holes, then mount this adaptor to the wheel, and then the middle holes would be what the tire shop uses...

Nope. What you're looking for is something like this:

Is this the wheel balance adapter that Warren needs ?

I believe so. Those were sold by Mainley by Design and they closed shop a few years back. I bought a gear shift knob from them and it was excellent. They had the wheel balancers too and I'm 99% certain that is it.

There's this one (no I don't know about shipping from Europe) :

This one(Europe too) : https://www.buttysbits.com/?pr...alance-machine-plate

CSP also sells one, but it's about 100 Euros.

A lot of guys buy these wheel adapters(they come in pairs) and either sell the other or gift it:

I have a Mainely by Design, but sadly they aren't around any more.

i had the mainley one, passed it on to new owner..i remember they had some cool oil pan filter where U didnt have to take off all those tiny nuts to drain oil..

This is the same as the Mainely Custom By Design version that Danny has:

Charles Navarro picked up some of the product line from Mainely Custom.

That’s a lot of cabbage. Must be the P markup.

Sometimes you can buy a single wide five wheel adapter on the SAMBA cheap,  bolt it to each wide five wheel you need to mount and balance.

ln engineering does everything Porsche, parts, motor overhauls etc. They are very pricey.

@wardog (Warren)  I live in Lumberton, TX and work in Beaumont.  Not sure how far into Louisiana you are, but I would be glad to loan you my adapter.

Thanks everybody! Greg from Vintage is going to hook me up!  Hey James, thanks for the offer! I'd like to have one for future needs but I really appreciate it.

I no longer have a use for my Mainly balance adapter shown above. If anyone wants it, it'll go for $100 and postage cost.

I bought mine from Ron Lummus Racing.  Go under wheels and tires and you will see a wide 5 balancer.   www.ronlummusracing.com

Wow, that one is pricy too!

I think somebody with a CNC lathe and mill setup should make these. Half-inch thick plate aluminum, a circle drill jig and a 12 x 1.5mm tap. Easy-peasy.

On second thought, you could water-jet cut the whole thing, then tap the holes. BAM!

Go for it Danny. you don't need 1/2" either.......jump on it Dude....easy $$$$ for a retired guy, eh ? How much for the setup..? ....how many can you sell at about $10 profit each. You could probably make more money as a wire splicer on the side.

Thanks again everyone for the help. This forum and the people in it are the best!  

David & swdoering, thanks for the offer and the link! I have one on the way but truly appreciate your help.

Somebody with a flatbed laser could blow those out in batches of 100 in an hour or less. Tap the holes on a mill and you're done before lunch.

Thanks, David, but I'm good. I've got a hobby business in my retirement. I help selected people with engine, transaxle, and motor work.

In my initial post, I said "somebody with" so that would be not me, and someone already set up.
