Question

tube size~ 700x35c /27x1 3/8

its for a Trek.

As puncture resistant as possible and not latex.

any idea's please?

Answer 1

They make self sealing tubes,  These can be purchased at most bike shops and some retail stores.  However, I recommend you buy tire liners.  This is a strip of flexible plastic that fits between tube and tire and protects the tube from punctures.

They do make extra thick 'thorn resistant' tubes but these are heavy and do not work as well as tire liners.  Tire liners are only found in bike shops.

Answer 2

Why not fit a standard self sealing tube tube and then put a puncture resistant plastic liner around the inside of the tyre.
