I am running Nokian NBX Lite 26" tires on my Sun DS2-XC's. From what I have read about the DS1's and them being really hard to put tires on, unfortunately seems to apply to the DS2's as well.

Anyways I am having a hard time getting the last remaining bit of the tire bead back onto the rim after replacing a tube. I have tried tire levers but stopped for now, it just seems really tough and I don't want to destroy the tube or the tire.

On the very outer edge there is a flimsy rubber part that seems to have separated a little from the stronger part of the tire bead, I don't know what has caused it. I don't know if this is really bad, or if it is normal for this part to get chewed up after replacing tires etc. I am affraid I will have to buy new tires or something. It has worn in others areas even more, Its hard to imagine these things not detaching when taking the tires off on these rims.

Sorry if this sounds like a really basic question :(

Hmm I was able to get the tire on and back on my bike, seems to be riding fine, I am not sure what the point of this weird strand of rubber is. It is honestly so flimsy that you could pull it off with your hands without any force, I can't imagine it not being damaged by tire levers or anything. Hopefully it holds up.

I had the same problem only worse on a set of bran-new Nokian's. The wire bead seperated from the rubber that was supposed to encase it before my first ride making the tire useless. In my opinion it was bad quality control on the part of Nokian which is why I will never buy another one. Maxxis all the way...

I have Nokian studs. Mount and ground. Great tires once they are on.

Quite a wrestle getting them there lots of soap and water.

I have been doing lots of riding around in the street since I don't have a second bike for commuting, so I imagine beentween trail riding and that these tires might wear down pretty quickly, I will see how they hold up and then looking into some nicer tires (not Nokian).

Maybe next time I will try with soap and water, what do I do just take a sponge and wet the bead all the way around and try like normal?
