I am looking for feedback on tire liners.

I recently had a flat that had two holes made by small slivers of
glass.

I use Continental City Ride tires at about 45 p.s.i. on an old Raleigh
3-speed.

I read some reviews on tire liners, but got conflicting experiences
with the same tire liner.

What has been your experience?

Do thicker inner tubes help?
