I have a tire issue that I hope someone can help with. A year ago I hung a pair of 1 yr old Pasela TG 35's on a hook in the garage. I recently went to re-install them on my Sam and one of them will not seat evenly all the way around the rim (Velocity Dyad) no matter what I do. I put several hundred miles on these before mothballing them and they were fine.
Any idea what might have happened, or how to fix it? Can I just hope to "ride it round" again over time.
Thanks in advance.

Maybe try soapy water around the bead then air it up w/ a compressor
to get it to pop into place. Similar to how a tubeless gets set.

If you can ride them. Pump them up and put a few miles on them. I did this with a set of marathons that were folded up in storage too long and it evened them out. It got better over time.

Coincidental to see this post. Just got back from a ride, and had the
same problem today, with Jack Browns on OCR Velocity rear rim.
Flatted in the midst of gale force winds (riding up Old Donner Pass Rd
in the Sierra). Threw a new tube in the JAck Brown, and the thing has
a serious assymetrical low spot opposite the valve stem. Stopped the
ride, deflated the tire, reinflated, same problem. Rode back over the
pass, about 15 miles, and the thing is still completely unbalanced.

have never had this problem previously. Hmmm. The wheel/rim/tire
appears to ride ok - - aside from the asymmetrical flat spot but I'm
worried about a sudden pinch flat, or the tire rolling off the rim
during a steep descent.

Oh how we all hate that...
I wish I knew a quick remedy... but the best way to attack this seems
to start with soapy water and lots of air...

When this has failed to fix the problem I have resorted to leaving the
soapiness on the tire, overinflating the tire and riding it around.
This has often worked for me... give it a try.

Peace,

If it's the problem I'm picturing in my mind, the bead is seated too
deap opposite the valve. One other solution may be to deflate the
tube to about 10psi or so and re-seat the bead evenly around by thumb
pressure. Loosen the stem nut all the way too.

Have had it happen a couple of times, usually on my 26" wheel bikes.
(Including the Atlantis when I had that bike.)

Well I'm glad to know I'm not the only one with this frustration. Yes, in my case, like Max's, there is a low spot caused by the bead not seating out in the correct position, though mine is just to one side of the valve stem, not on the opposite side.

I previously thought this poroblem was the product of some particular rim - tire combos. I have an old set of 26" Araya twin-hollow type rims that have never taken any Schwalbe tire, though my old Ritchey mtb tires seat just fine. I had assumed that the problem was a combination of a slightly small bead and the fact that twin hollow profiles provide a place for the bead to "go"- between the hollows- that a box section rim didn't. But my current problem doesn't follow that pattern.

Maybe I'll try the soap and ride technique next.

Thanks

Pete

Problem solved, with the soap suds solution:

Deflated tire. Liberal application of of soapy water at the bead.
Inflate a bit, work the tire to get it seated, that inflate the rest
of the way. Most of the asymmetry was gone by that point, then I
worked it a bit with a Park Tire Seating tool - - basically a set of
channelocks with concave grip for the tire - - and the tire now seats
perfectly and looks great.

best,

Max
