changing tires
 

I am changing my tires for the first time and i am a bot of a noob. I bought some more aggressive tires for better traction in the snow. I did the front tire first. Everything seem to go well except when i put the tube back in part of the tube seemed cramped in part of the rim. I tried to fix it but every other part of the tube was stretched out smoothly so i finished putting the tire back on the rim and filled it quite a bit. Everything seems okay but will that cramped part cause problems? Or did it fix itself when it filled up more?

Yes, it will be a problem if the tube is caught between the tire and the rim. It will eventually blow, with a very loud bang. It is important to get the tube inside all the way and the tire seated correctly. I have ruined tires because of being in a hurry and not checking to make sure everything was correct.

It depends on what you mean by "cramped". If it was wrinkled but not caught between the tire and the rim then it's OK. As said above, if any part of the tube is caught between the tire and the rim it will most likely blow.

After you have the tire install, inflate to about 10 psi, and go aound each side of the rim pushing the the tire in from the sidewall to ensure that no part of the tube is trapped between the tire bead and the rim. Then inflate to full pressure.

You have to look between the tire and the sidewall while you are doing this. Usually the tube will pop into place but occasionally it will remain stuck rather than popping into place. If that happens you usually need to pull the tire bead off and start over.
