I got new type-s wheels with tires already mounted with TPMS insde. The tires are not on the car. So when I went to check out the condition of the tires, I rolled it, and noticed that there was some noise. It sounded like a small ball rolling inside the tires (like a marble rolling down a plastic pipe. I am just curious to what this noise. Does anyone have any idea?

With the non-TPMS valve stems-When the people cut the valve stem before removal, the inner ball of the stem can fall inside the tire hence the rolling noise. Might even be a rivet or part from the TPMS assembly.

Definitely something inside the tire. I've seen it happen before. It has the potential to make a balancing nightmare.

Is that bad thing? I was planning to replace the TPMS with valve system. Will that be a better option?

Something? what could it be? lol. So why would it make balancing a nightmare?

As the tire gets up to speed it's going to eventually stick to one spot and stay there throwing it off balance. It will change position every time you take off so there's no way to balance it.

It would take a little bit of weight to throw things off but look at how little weight they add to the rims to balance your tires. This thing that's rolling around inside of your tire is on the outside diameter so it will have even more of an effect. If it's extremely light you might not notice it. If not, it will be out of balance at high speeds.

If you're going to replace the TPMS sensors with a regular valve stem, the shop will need to break the tire down in order to remove the sensor and install the rubber stem so have them remove what ever the object might be. Post it here to complete the puzzle.

Will do. Is it bad to have the wheel run on valve system by the way?

When you say run on a valve stem, are you asking about running the car on a standard valve, not TPMS. No problem, unless the car is equipped with a TPM system, then the alarm will sound evertime you start the car and the display will be lit.

If the car is an '06 or above you can always make an air tight container with the 4 TPMS sensors inside and keep in trunk.

Replaced it with the valve system and took out the TPMS and still that ball rolling noise still occurred. Any idea?

Jesstzn

Did you tell the tire shop there was a noise so they could look for it ? If not they would have just broke the bead and removed the tpms and and wouldn't have looked for it or even totally removed the tire from the rim.
