Paul,
I've used Schwalbe Marathon Pluses for a couple of years now. They are great tires. As they age though, they tend to be more susceptible to flats. Recently, my wife's tire had a sliver of glass that went past the Smart Guard layer (5 mm thick, Schwalbe claims) and just barely nicked the Schwalbe AV17 tube, causing a slow leak. I've ordered Mr. Tuffy liners, but was wondering if you used any talcum powder on the inside of the tires, as I've heard some people suggest? Also, have you checked for any abrasion on the inner tube where the Tuffy liner ends meet? Any problems there? Thanks.
Just checked my records on one of our Schwalbe Marathon Pluses, in this case, one my wife has been riding on. She rode on it for 23 months and 6202 miles with no flats. After that, she started to get a few flats, five over a period of 32 months and 8668 miles. So, as the Marathon Plus ages, it becomes more susceptible to flats. These flats were caused by long slivers of glass or tacks/nails. I am going to try the lightweight Mr. Tuffy liner on her tire because, believe it or not, the treads are still good--only pockmarked.
