Orderd a set of Stop Flats 2 tire liners along w/a set of Schwalbe Marathon Plus and tubes. The Stop Flats 2 product advertizes itself as having a 'hard plastic' surface towards the inside of the tires and a softer coating towards the tube. The implication being a combo of Spinskinz and Mr Tuffys. Well, its a straight up croc. What you receive in effect is a 2-toned Mr tuffy. There's NO descernable difference in the 'hardness' of the 2 different colored material that make up the liner. So, I'm calling BS on this product.

I'm a hardcore Nu-teck guy and wanted to give pneumatics a shot, so I got the, generally conceded, best on the market. 700x28mm. LOVE the tires, hate the liners. Stick w/Spinskinz and Mr Tuffys and avoid this product.

I thought they were Mr Tuffy's and they had just changed their name?

Have you had any flats?

they are mr tuffys with a namechange, they do have two densities of polymer in the liners, and why you would ever think about putting tuffies in marathon plusses is beyond me.

I have purchased my 1st set of the marathon plus and I am 1,600 miles into them with no flats. I don't know why you would want to add the extra weight. They are already heavy enough.

Put some slime in there, too.

You're probably right. My bad.

Yes, as a matter of fact I had a huge blowout less than 1 mile into my commute. Later, I fgured out I'd over pumped the tube and it blew right where the liner ended. No damage to the tire, though...it just blew the bead off the rim.

Wiseass... Get a life.

Like I said in the beginning of the post, I'm an airless tire guy(for commuting)and wanted to eliminate all the variables. Marathon Plus w/liners still roll faster than airless.

I'm like nashcommguy in that i get a little bit fanatical about not getting flats for reasons of convenience and money-saving. I've never had a Marathon Plus tire or an airless tire, but I tried using more than one tire liner inside a kevlar-belted bontrager tire, and the stupid bits of wire/glass one picks up in Philadelphia still would poke through. I noticed, however, that the types of 26" tires with lots of rubber, that provide at least 5mm of distance between the tube and the road surface.... never get flats from these common bits of glass and wire we have here that are less than 4mm long. (who would have guessed!) I have become convinced that a way to avoid flats where I live is to avoid tires that allow the tube to come within 5mm of the road surface. I'm thinking about inserting one of the lightweight pieces of foam pipe-insulation you can buy at Home Despot as a buffer between my tube and the road. (This will do nothing against nails, but I had 1 or 2 nails drive themselves through my kevlar belted tire when I was using it, anyway)
