dismounting tires question

[PoorOwner]

do you need use lube when dismounting tires on a tire changer? I have seen people put it on the duckhead, all around the bead, or none at all.

 

[Old Man Roger]

I've never needed it while dismounting. Maybe some of the new super thin tires might?

A long time ago when i went to tire school, they taught us to use lube but, i don't use lube when dismounting tires. Mounting, absolutely a little dab will do you.

It might also depend on the presence of rust too.

I unfortunately have watched tire techs dismount tires without using lube daily for over 15 years now. I've been guilty of it myself from time to time too.

The truth is, lubing the beads of a tire to be dismounted lessens the chance of damaging or tearing the beads of the tire coming off and causes less wear and tear on the machine.

Doesn't hurt.

helps but not needed

 

[txvwnut]

Yes. Stiff sidewall and old tires lube helps.

Rarely I lube during dismount. But if it's low pro and stiff I'll spray some silicone spray or what ever is within reach. Never any issues.

Haven't ever seen it done either, of course couldn't hurt. Most all the motorcycle tires we remove come off the rim without problem. Going on can be another story though

I haven't done a ton of tires, but the ones I did I found that lube on dismount made things easier. And took about 2 seconds to do. Once you break the bead the put it on the machine, the round lube brush fits right in between the bead and rim and you just drag it around quick in a circle.

I'm sure it's not required (and like AngryJoe says most tires being dismounted are going in the garbage anyways) but I think it's something that makes things go a little easier. You don't get that high pitched ear piercing friction squeal noise, or the chatter you sometimes get. Just goes around smooth and easy.

I'd imagine it's also easier on the tire machine with a little lube. Which might not be a concern of yours if you just work in a shop, but more so if you own the shop / machine yourself.

I do use it during dismount and install. I spray soapy water on the bead as I break the top and brush lune on the bottom roller as it rotates. It helps tremendously.

It's personal preference, it has a lot to do with the type of machine you're using the age of the tire and the sidewall height. Most of the time now the tire needs zero Lube to be removed. When dismounting say a 245 40, a little bit of lube helps keep the tire from rolling back onto the lip of the rim

I cut my teeth working on bmws with lots of low profile and run flat tires. We used lube for removal and installation. I can see not needing it for 70 series tires, especially if they’re going in the recycle pile.

I use it from time to time on stubborn motorcycle tyres, usually not though.

Tires, wheels and tire machines come in many different sizes and types. Back in the bad old days of 13", 14" and 15" stiff tires on steel wheels, we used Ru-Glide by the gallon. Many of today's are soft, limber 18", 19" 20" and up. They slide on like rubber bands.

I mount all my own motorcycle tires with tire irons. No fancy machines.

Yes, I use real tire mounting lube (RuGlyde). I put some in a spray bottle and spritz it on.

Anything that reduces the force required is a good thing, and lubing to remove tires definitely helps. Sure, it's possible to demount tires dry, but why not make your life easier?

 

[sberry]

I been making my own glyde but its probably not a whole lot cheaper. 80% anti freeze, some crop or veg oil, crop is water soluable and a shot of liquid soap.

I almost exclusively do performance and race tires and a lot of tire "flipping" where you dismount a tire and put it back on the same wheel with the former inside on the outside (due to camber wear) and have used lube to dismount a tire one time that I could remember. Out of thousands of tires a year (just did about 100-150 tires at an event this past long weekend). I just don't see the need, but I have good Hunter equipment and am fairly skilled.

That said, using it really wouldn't hurt anything and preferring to use it wouldn't be a failing of skill in my eyes

At 150 tires in a weekend, I'd say you're experienced..lol I'm not sure I did that many in a week when I worked as a tire changer.

Good equipment, good operator, not required for dismount.

I have seen hundreds MOUNTED without lube, but I don't recommend it.

Mobile OTR truck tire busters use a gallon bottle of water with a squirt or two of their favorite liquid dish soap for lube. Because they do all the work with special sledge hammers and long bars/spoons (6') they use a LOT of lube for dismount as well as mounting.

I do the same. I put a high concentration of dawn dish soap with water in a spray bottle and spray the bead a little during dismount, then a whole lot for install. Been doing it this way for many years.
