So, I had a tube blow out a few weeks ago at 35 mph
I bought a replacement tube from the local shop. The old one was 2.5x10, and that's what I asked for, but the guy brought back a 2.75/3.0x10 and said it would fit.
So, I installed the tube, but now the tire is out of round. I've checked it, deflated it and reinflated a few times, but the problem perisists. I also couldn't get the valve stem to seat properly. It's an angled one, and the base won't go flush through the rim; it might if I really beat on it. It's also not a screw in like the old one.
My question is whether my problem is user error or the wrong part. What do you guys think?
-BTW, the new tube is made in India by Prima.

Re: '97 Elite (SA50) Inner Tube Questions
I've narrowed it down to the tire not seating.
How much air should I use to seat it? I've been pumping it to 40 psi, a la car tire, but it won't seat. Tried lubing it too.

Greetings:
I'd remove the tire completely and check the bead for kinks and the carcass for any obvious flaws. Could it be that the tube went south because the tire's delaminating. There's a number stamped on the sidewall that indicates the week/year the tire was cooked. If it ends in 04 or less, just get a new one, unless your saftey's not worth $25. Most 5-year-old tires hold together just fine, but some don't.

I had a Spree tire blow out on me last year. Sounded like a gunshot at ~25mph. Almost dumped the bike too.scooterwerx wrote:out of balance tires are a scary thing, especially when they are so small!
I will admit, the tire was pretty bad, too many one wheel peels with the new scoot

You've got a point Wheelman...
I examined it and it seemed okay when off the rim.
But you guys didn't answer my question, how much pressure does it usually take to seat the beads?

A tube-type tire on a tube-type rim will not need to "seat" violently like a car tire. I hand-mounted my Pirelli and a new tube, adding pressure with a foot pump. The tire found its way gradually down to the rim flange and was correctly centered without any special effort on my part. Of course it was a new tire...

Sounds like I won't go with my plan of finding a cage to put it in and taking it to 60ish.
Thanks Wheeldude.
