Mounting 18" tires

[chuckthebeatertruck]

I had a new tubeless Dunlop that would not seat at 100 psi. I let a local shop inflate it in a cage. It took 120 psi to pop.

The risk of a belt separation down the road is very real when a tire has been treated in such a fashion.

Bought 18" Firestone tires from Coker .I can not get the raised edge close to rim to be even all the way around the rim.I thnk the raised bead maybe a locator.It is wider on one side than the other. Making it look like tire id not centered on the rim ?

DANPATCH,

Have you gotten your tires properly mounted yet?
If you have not, photos of the actual problem are very helpful.

On a side note, Tire inflation should not exceed 40-50 PSI when seating the bead. If things are all correct, tires for a motorcycles will seat between 20-30 PSI. If it doesn't seat both beads by 40-50 PSI, something is wrong.

Be careful around tires,
I hope this helps,

I’ve noticed in recent years tires are getting tighter and the bead doesn’t want to seat as easily, especially on modern tubeless tires. I had a new tubeless Dunlop that would not seat at 100 psi. I let a local shop inflate it in a cage. It took 120 psi to pop. I even polished the inside of the rim as to reduce friction.

... Boiling hot sun is not a problem so tires are pliable, but using RU-GLYDE makes application much easier. Also, it will not attack rubber, or paint and that is serious problem with many slimey, gooey concoctions people are tempted to use.

So you were spoiled, Eric,

As here in the Midwest, we often had to put them in the front seats of our autos and shut the windows.

Attacking rubber, paint, or just causing corrosion is a serious concern,.. unless you are on the side of the road.

Then beer works. In moderation as always.

PS:

...The tighter a tire fits on a rim is like a belt on baggy pants.

Please explain.

Thanks in advance,

As Steve said; use RU-GLYDE. Here in Florida, Boling hot sun is not a problem so tires are pliable, but using RU-GLYDE makes application much easier. Also, it will not attack rubber, or paint and that is serious problem with many slimey, gooey concoctions people are tempted to use. The tighter a tire fits on a rim is like a belt on baggy pants.

I always let them warm up on cement in the sun and then use RU-GLYDE.
Everything is getting harder now days.

Yes I tried several lubricants

Did you try to massage it with a mallet, Dan?

Sometimes they need discipline.

Are you using tire mounting lube? It needs to be able to shift to center itself.
