Did you mean Schraeder valve, Presta cores are NOT removable.

What tool do I need to use and how do I do it? Thnx

I've had to toss only a couple defective ones due to faulty valves in about 15 years of riding. When you buy them, look for thin or stressed rubber around the base of the stem, often this is a sign of a low quality tube. My defective ones were Fishers, I only buy Pyramid mostly anymore, which are made by Kenda and very affordable. I've actually had good luck with Performance tubes too.

thnx for the input bro but I'm looking to fill the tube with slime, and need to remove the core for that reason.

Conti and Schwalbe tubes have removable presta valves. Other than those you can force the locking nut off the valve pin and let the core drop into the tube. After you put in the Slime, find the core, work it back into the valve stem and replace the nut.

I would just get the Conti or Schwalbe tubes.

That sounds like the move, thanks for the scoop
