Question on mounting clinchers HELP !

[Steve Swan]

hope you dont mind my getting in your questions/answers but i would like to know from folks that have actually lost a clincher as to why. the only one i lost was prob. my fault im thinking. as i did not check air pressure one time it happened. tube had the valve steam ripped off the tube. i assume pressure being low allowed the tire to slip on the rim and rip off the steam. have other folks seen this or is the steam still intact? after that ride to the ditch i drilled opposite the steams and installed tire locks. do still check psi before riding too. thanks. gary

Gary, i'm good for all the talk on this clincher topic as we can get.

What i have been hearing, tire air pressures should be checked EVERY ride, around 35 psi for 3.85x20.

I had a new clincher tire pop off as I was filling with air, after mounting. It was a frightening experience and I had nightmares thinking that a clincher could pop off when riding. So here's what I did to prevent clincher pop offs.
1. I used a wax and silicone remover solvent to wash off any mold release on the tire bead.
2. I scuffed the tire bead with 80 grit sand paper.
3. I sandblasted off the slippery shiny paint inside the rim clincher area. (this required some creative masking techniques to protect an assembled wheel)
4. I used no lube to mount the tires.
5. Initially ran with 45 psi for a coupe of hundred miles. I found the ride to be terrible with this high psi.
I'm down to 30 psi and now high speed handling is better and the ride is softer.

Probably, no one has done all this but I feel safer and sleep better.

Steve, maybe you should consult this lady.

[Steve Swan]

Wow.... she rocks ! She is a babe ! Hopefully I'll be at least half the man ! The only thing she's missing is a grin.....! btw, what a wonderful picture !

[Steve Swan]

Wonder if she'd give me that tool kit ?

Where did you obtain "wax & silicone remover" ?

[harleytoprock]

Any auto paint supplier will have wax and silicone remover. About $12. a quart.

Today is my first day of so called 'retirement' and yesterday was my last day of work after 43 years service in healthcare; amazing and actually pretty disgusting the past 4 years to be on the sheeit.end of the stick feeling the brunt of the corporatizing of health care. i've always worked in the trenches and with corporatization, we've experienced breath taking staff cuts while the corporation gives Peyton Manning $4mil to be spokesman for one year. his voice is in a barrage of ads on all the radio stations and his voice answers the phone when a customer calls and staff are too busy to be near the phone to answer it. It's being said in 50 years about 6 major corporations will own and operate all the healthcare providers in the country. healthcare delivery is being ravaged by corporate administrators interested only in the bottom line. All that being said, these 43 years have enriched my life immeasurably. around 30 of those 43 years have been in mental health and substance use. Happy retirement, Steve !

i really appreciate all the posts i've got on the clincher rim topic. especially enjoyed the pic from Eric of the gal putting on tires on her bike around 1915 or so. looks like both front and rear wheels are off her bike. Would appreciate hearing comments on the white inner tube lying on the ground..... !? is her bike somewhere near the 1915 year ?

i've concluded Coker 3.85x20 tires are a different and perhaps less pliable compound than tires from the 20's era. if not a harder compound, then the Coker's are stiffer. oh well, it really does not matter.

Today, i took an old rusted cl.rim and cut the bead off one side of the rim. as "harleytoprock" mentioned the late Gene Baron making up a tire stretcher, my plan is to make up a similar tool using a screw jack to stretch the diameter of the tire enough to slip it over my restored wheels' rims. other than use a tire iron, i did not use or do anything special to get the tire on this modified rim. i was duly impressed how differently the clincher tire behaves during installation compared to a drop center tire going on it's rim. Without a doubt, the tire will go on a standard 20" rim, but not without at least toasting a few hours in the hot sunshine. i figure what the heck, if the tool doesn't do the trick, then i'll muscle 'em on with my getting old hands. Either way, i can't let my self be outdone by a girl who made it look relatively effortless over 100 years ago. here's a couple pics of the one tire on the modified rim. waiting for my jack to arrive in the mail. once i get the jack, more pics to follow. until then, i'm leaving the tire on the modified rim to help stretch it a bit

i am really impressed how very nice the 3.85x20 setup looks in contrast to the 4.00x19, side by side the 3.85x20 has very visibly larger diameter and narrower width. will definitely give it more of a bicycle look. i can hardly wait to get the wheels finished. Wednesday, this was my drive into work, 15" overnight. Tuesday, the high was 74 degrees. C'mon, sunshine !!!!!

I've heard to put rim inside tire,then work beads over rim from both sides.

Steve, thank you for your years of service in the healthcare field. People don't realize how vital doctors, nurses, and caregivers are until they need them.

Amen to that Eric.

^^And congrats on the retirement, you'll have more time now to spend with your toys, right?

[Steve Swan]

Thank you, Gentleman ! one of the most amazing aspects of my life work has been, "i've never seen it all." just when i thought i did or had, the uniqueness of our humanity would reveal it's self in a way i had not seen or heard until that moment. With the utmost of dignity, grace and courage i've seen people rise to tragedy and challenges. and at other times marvel how someone could behave or have the perception they did and survive as long as they had.

and yes, more time to spend with the toys, but also to get out and experience more of the fullness and goodness of life.
