getting waves out of new tires?

Okay, for years I've just filled them up to max psi, deflate, repeat a few times, then ride them wavey for a while (like a few days, or around the block a few times) until the waveyness goes away. Is there a better way?

The waves are from being folded for so long. Know what I'm talking about?

I just lay them out in my garage for a few days. It doesn't completely straighten the bead but it works well enough that I can get them on the wheel without having to fight them.

By wavey do you mean the tire wobbles even though the rim is perfectly true?

Different tires and rim combinations seem to create a mixed bag of wavey-ness. In my experience, Continental Explorers are the best bead-seating tires I've used, I just pump them up and they're always straight without any fuss. One the the worst is the Geax Sturdy, but I love this tire so I put up with it. Pumping up the tire to the correct air pressure just doesn't "plop" the beads in place and it stays wavey no matter what.

I've fixed this by first inflating the tire to about 5-7 psi... then I "knead" the tire where needed until the wave is gone. I look at both sides and check where the tire bead is sunken-in too much or showing-up too high. Once the tire spins nice and true with the rim, I pump it up to full pressure.

The waves are like you said, but from being folded for so long. I've never had such an issue before (normally I just ride and they "work" themselves out.) Its not the bead, that is seated correct, its the upper. But these specialized tires, damn, are a mess, even tubless.

I have occasionally run across tires molded a bit out of round or askew.

Oh wow... I've never come across anything like that.

I can't see the molds being wrong... I work for a company that used to be a plastics molding company. The only thing I can think of is, those tires must've been folded or packaged way too early before the rubber has fully cured after coming off the mold... that, or stacked badly in hot storage.

Given the opportunity, I would return a tire like that and get a new replacement. That's definitely a faulty tire and should be covered under some sort of manufacturer's warranty.
