How do the various bicycle tire anti-puncture strips compare: Kevlar, Slime, etc?

Question

I am asking about the anti-puncture strips that go between the inner tube and the tire.

Thanks to all who contribute.

Answer 1

Ride!urb is right, in my experience, anti flat tapes  are no where near as good as puncture proofed tyres, and as a back up, fit a self healing inner tube.

Some of the tapes tend to split along the length and pinch the tyre and can be difficult to fit.

Schwalbe tyres start from about £10 depending on the type and sludge tubes from about £6.

Answer 2

A kevlar casing is by far the best.   The only time I used a Slimed tube I got a flat so I consider that stuff crapola.

Answer 3

The best choice by far is a tire that has an internal puncture-resistant belt (Kevlar, Aramid, etc).   They blow away any other method of flat-prevention on the market.  

If you have a road bike, then I'd probably get the Slime strips unless you do a lot of city cycling or seem to be picking up items like heavy staples, tacks, etc.   In that case, the Mr. Tuffy liners are better, but they're a bit stiff.   The Spinskins type kevlar strips don't have a good track record....there are lots and lots of dissatisfied customers that have found they wear holes in the tube or disintegrate in 600-3000 miles.  The mfr knows this and finally addressed it (on the packaging, not by improving the product, because they can't really).  They work well, but I think they're way too expensive for a product that has some obvious problems and a short life.  

If you're using larger tires (hybrid, mountain bike, cruiser), then use Slime in the tubes or buy the pre-filled Slime tubes.  

Really, my top vote is for puncture-resistant tires, though.  

Hope this helps some.   :o)
