So uh... tire/valve stem alignment, 1 side only?
#51
When you stop to fix a flat, sometimes in the initial examination you find the hole in the tire, but sometimes you don't or you aren't sure. Then you have to find the leak in the tube and match it up with the sometimes hidden object lodged in the tire that made the leak, and remove it or else you get another flat in a couple miles.
It's a PITA that tire manufacturers decided that having 2 logos was worth more to them than our need to find the hole in the tire. So now unless you're really careful with tire/tube alignment after you take off the flatted tire, you have to say the hole is either here . . . or there. I much preferred the old way of having the logo on one side only. Logo went over the valve stem on the QR side. Then it was much easier to figure it out.

I haven't used tire levers in 20 years. I don't carry them. I find that I can't see the inside of the tire as well that way, so it's harder to see what came through or find the piece of radial wire, etc. It's at least as quick to pop the whole tire and tube assembly off at once by hand, since the first bead only takes seconds to remount by hand. And then I'm certain I've seen and removed any problems. I'm also backward from some experts, in that I mount the bead at the valve first and the opposite side last, by hand of course. Just my experience and method.

I don't know what tire rim combo you are using but there is no way I could pop off the first bead by hand. That what the levers are for. Then I put them away as I never use levers to install a tire.

WTF are you talking about?
If you are kidding then...uh..ha, ha? If you are trolling then bite me.
If not, I think you misunderstood.
The alignment of the valve stem and the tire logo isn't to help you find the lalve hole on the rim (although several brands help with this by using different coloured spokes). It is so than once you find the hole IN THE TUBE that caused your flat, you know where to look on the tire for debris that may still be embedded there and that will cause another flat.

You can just as easily find the spot in the tire to check by referencing the position of the valve stem in the wheel, regardless of if you have the label lined up. Lining up the label, while it sounds logical, is unnecessary -- but still used to justify yet another cycling ritual. I'm sure someone will chime in about the tire moving around the rim -- people have a hard time giving up their religions -- I'll just say you can believe what you want.

I thought the different colored spoke was slightly heavier to balance the weight of the weld. Have I fallen victim to another one?

Not the first bead. Around here, we pop the whole thing off at once, both beads with the tube inside. It's not hard. I've done it with pretty much any rim and tire combo on which I've happened to change a tube. Exception for an early Cane Creek wheel that was almost impossible with levers.

In case anyone is surprised I say that wire bead tires are actually looser, that is in fact the case. Since they don't stretch as much over their lifetime as Kevlar bead tires do, they don't have to start out as tight. Lots of things are possible with wire bead tires that are not with folding tires.

The way Presta valves are made, they do not allow any sort of dirt or water entry when the valve sealing nut on the end is closed. A cap is not necessary to seal out the elements. This is not the case on Schrader valves with removable valve core. Dirt and moisture can get inside those and cause problems, making the valve cap a necessity.
