Any old tire busters out there?

[Roothawg]

Having a problem getting the new tires for the fly to seat for the intial airing up. I know about the old trick wher ya light the starting fluid but these are magnesium and I would rather not do that. Last resort would be taking it to a tire shop and having them do it on the machine but I am cheap........

make sure the schrader valve is removed from the valve stem.

use a motorcycle tie down to cinch down the center of the tire (tread).

should work...

[Roothawg]

Cool man thanks. I'll giver a try.

Sometimes it helps to take the restrictive tip off your air blower to get the most air in the tire as quickly as possible.

Take it to a tire shop that does truck tires.They will put a bead sealer goop on the bead that look's like stringy Murphy'Oil Soap and use a pressurized 10 gal. can of air with a 2 inch ball valve feeding a wide mouth tip.Air chuck on valve stem,ct loose the ball valve and instant seat of the bead. He'll probly do it for free !

I vote for a ratchet strap.... All though, have not done it personally with a large tire.

[Fat Hack]

The strap around the middle of the tread is a good idea for the home based tire buster, and it's the way old tire busters like myself HAD to do some of the oddball trailer and ATC tires and wheels that came along once in a while.

When I worked with semi truck tires, we had a big metal canister that had a large, flat discharge nozzle. The can would hold compressed air, and could be handled with two hands by a single person. Pulling the 'trigger' discharged a HUGE blast of air into the tire and often did the trick in just one try. ALOT safer than the lighter and starting fluid trick!

That basic principle can work for ya at home, but you need a good compressor with a BIG discharge nozzle!

Try the strap first.

(A combination of the strap PLUS air fired into the tire from the bead area might work, too.)

I got it but I haven't had any luck with the out of round problem. That freakin thing is still 1/4" out of round. I built a homemade giant dial indicator out of a sawhorse, a level and other various junk. I don't understand why these freakin tires won't center on the rim. I even greased the bead area to try and speed that process up. WTF?

[DrJ]

That big of a bump sounds like a separated tread.
Unless the "bump" moves around to different parts of the tire when you remount it.
Is the high spot alway in the same part of the tread?

(We don't care how they do it outside of California...) http://www.jalopyjournal.com/ubbthreads/images/graemlins/grin.gif

DrJ, he had the same problem with the radials. Are you sure the rims are straight and true.?

[CURIOUS RASH]

<font color="green"> Them some old rims.

Can it be that the bead design has changed enough over the years?

Pretend I know nothing about tires and wheels

I have used the strap around the center and it's worked for me most of the times..
I've also used wood blocks to hold the bead apart overnight. It give's you a little more width when it's time to mount them.

however, I also have a friend that has a set of magnesium hilibrand's that require tubes..
i'm not sure if it was because of bead design or pourosity of the wheel.

I just had the same problem with a loader tire at work the other day. Bead wouldn't seat straight for crap. We had the tire laying down on the ground...I stood it up on end with the problem area at the top. Then, inflate the tire to about 15-20 psi. then, once beads are seated and minimal air in tire, lay it down and slug the sidewall with a rubber mallet. If the beads are lubed up pretty well, they should work themselves out sooner or later.

For regular car tires we have a machine that will run a plastic wheel around the bead and help it seat. The rubber mallet works fine for stuff that isn't 20" aluminium on a stupid honda.

Good luck!

The wheels are cast. They are the American Racing 12 spoke , spindle mount. I had this problem at the track so I bought brand new tires made for drag racing. These are bias instead of the radials. I lubed up the bead aired it up to 10 lbs bounced it on the low side. Aired it up to 60 lbs beat on it with a mallet.....it never ends. Tomorrow the wheels go to the tire shop and they can jack with it.

This kinda weird crap happens to me only because I am so lucky.....

[CURIOUS RASH]

<font color="green">It happens to you cuz you are so damn purty.

Purty boys never win. </font>

[gowjob29]

Just go down to your friendly Discount Tire. I work there and they'll do it for free.

[Roothawg]

The tires never quite "pop" like the bead totally seats. I had about 60 lbs in em but I was afarid to put too much more in em. They are only a 4 ply drag tire. How much air do ya'll use to seat em?

[Roothawg]

Rashy, I thought once I bought my "lucky" John Force firesuit my luck would be like yours.....

[CURIOUS RASH]

<font color="green"> You want your luck to be like mine?

CONGRATS!

Was it all you hoped it would be? </font>

[KnuckleBuster]

Sometimes as little as 15-20 pounds will seat 'em, but I've had tires well over 65 pounds before they seat. Not really a good thing, but hey.

If they are old rims, they probably won't "pop." The newer rims have a pretty pronounced lip that causes the tires to pop, where the older stuff just sorta slides into place.

[CURIOUS RASH]

<font color="green"> Don't you think slapping them into the pavement at a high rate of speed would seat them if they were going to?

It's always done wonders for my head </font>

[Roothawg]

Ever had one that won't center up? I hope this isn't some defective crap that has been in some barn waiting for an ebay sucker for 45 years.......

[CURIOUS RASH]

<font color="green">HAve them spin em on a balancer without tires first and see what happens. </font>

[Roothawg]

The weird thing is it actually held air and we never noticed it til the car was jumping up and down as vd rash mentioned.

I can see the area that won't seat but can't do anything about it. I can get it closer but a wobble is a wobble.

[Roothawg]

The wheels are true...that I can tell. It's about 6 inches of bead that sits off center. It's not as pronounced as it was at the drags but it still ain't right.

[CURIOUS RASH]

<font color="green"> Could it be that those wheels are a hair larger/smaller in diameter than todays tires?

They look like they came off a FARMALL or some old combine.

Try the John Deere supplier next door. </font>

[Tony]

I've done what Knucklebuster said too, the mallet to the sidewall deal..
All but one tire ( one of them big ass low profile rollers) mounted for me.
I have also had up around 60 lbs to seat a bead..makes one hell of a bang once it does..
i've used everything from silicone, penetrating oil, and of course bead lube to get some on..
some are a bitch.

good luck..

Rat.

[Rocky]

You said it before, Root...take 'em to the tire shop and let some old grizzled, hairy-backed gorilla with mucho experience work his magic....

[Roothawg]

I figure if the shop tears it up they have insurance.......

[SamIyam]

Break them down, rotate the tire 180 degrees and then check to see if the "lump" is in the same spot... if so... it may be the wheel... When I popped the tires on the BFD 12 spokes... they did not pop like the hundreds of other tires I had installed before... I think it has a bit to do with the lube and probably more to do with the style of bead built into the rim... anyway, try rotating it and then measuring it... if it changes with the tire... it may be that the tire isn't seated or that the tire is off...
