Tire changing tips

#1
Anybody have any good tips on changing mini bike tires , maybe a inexpensive home made machine . I don't really want to buy a harbor freight p o c ,when I probably have enough scrap laying oround the shop to build my own. Just wondering if anybody may have any good tips that may have worked out for them? :helpsmilie::helpsmilie:

Also I've taken 3 3/4 pieces of ply wood and glued them together. Then cut a hole just slightly bigger than the rim. Put a solid piece of steel over it and used a hydrolic press. But I normally use a old cat foot peg and a B.F.H. If you do it right you won't ruin a tire. I haven't yet.
Good luck.

I had a 3wheeler with tubeless tires.. I cut through the sidewalls close to the rim with an old steak knife on both sides. I then used pb blaster to soak both sides and used 2 flathead screwdrivers to break the bead. Ive heard too many stories of guys taking their minibike rims to tire shops and getting the tires removed and the rims getting bent.

If the rims are two piece, remove the hardware and deflate the tire completely. Spray the bead of the the tire with WD40 on both sides. Then inflate the tire completely until the rims pops off. It may take a couple of trys. Tubes are cheaper than rims...

This worked like a charm :thumbsup: I twisted 2 crew drivers along the bead while it was inflated. I only had to fight one side, 3 out of 4 popped right off :smile: Thank you Jacks!

Thanks for the quick responds guys! I'll try them all and search for the video now. I really thought the tires would be the easiest part of the build but has proven to be the toughest so far!

That seems like a great idea. I will have to try that on my MX back wheel because the front wheel almost killed me. :laugh:

We have kids on here, as well as younger men with very little experience in mechanics.

Today most of our city is involved with a fund raiser to support an individual working at a large tire shop who had one explode in his face on May 16th. They landed a helo at the shop and flew him to Phoenix- the damage to his face was that bad.

Everyone who has read my posts over the years knows I am not a safety freak. I don't post about eye protection, helmets, or condoms.

However, anyone attempting to separate an unsecured a split rim wheel using air pressure is putting themselves at risk of eating a wheel half, or pieces of a wheel half, or rubber to the point where they require a medevac out of their back yard, several years of facial reconstruction surgery, and permanent disability and disfigurement. (If it doesn't kill them)

This includes over inflating ANY tire.

Please, do not do this, and if you do, do not talk about it. I fully realize some of us live dangerously, and have a clue as to how much air we're using, pop-offs in place, cages, etc.

I have posted before about using an old ford bumper jack.The base has curves in it that can get very close to the rim.Place the tire and rim under the base of the jack,then the bumper part under your trailer hitch or something solid.Jack up the jack....Presto

This posting is based on using discretionary common sense.... Seeing that most of the members are over the age of forty... I see no reason for concern...... Of corse everyone is entitled to an opinion....

Duly noted, looking back I could have put a chain through the center hole and around both wheel halves and the tire.

Don't worry about me. I am overly safe.:thumbsup: I still have all 10 fingers from working with the grinder/cut off wheel all the time. Thank you for the concerns Dave.:thumbsup:

I think you're a decent man, and do a nice job on restoring your bikes.

My comments have nothing to do with "my" opinion. There is nothing in your recommendation that would fly in any hot rod, or mechanic-based circles, nor be allowed in any tire shop.

135 PSI Yard Tractor with side wall damage. Most of our home compressors could handle this. Imagine what happens when the rust or corrosion between split 6" rims suddenly lets go at say, 30 PSI. Who is in the garage helping you?

Carry on. I realize people get ass hurt, but in this case, I don't give a damn.
