[net.bicycle] tire savers & such

fred@umcp-cs.UUCP (05/20/84)

In reference to the recent discussion of tire savers: No one seems
to have mentioned this:

I have installed on my bike two strips of PVC plastic of about the
width of the tire tread and about 1/8" thick, inside the tire
between it and the inner tube, for preventing flats.  They don't
seem to add noticeably to the weight of the wheel. The pair I bought
were sold under the trade name: ``Mr. Tuffy'', and cost $11.

Do they work? Well, I haven't had a flat with them in, but I haven't
been using them for a long enough to tell.

Anyone else have any opinions on these?

I commute more than 20 miles per day.  For the first 6 months of my commute
I had flats every 2 to 4 weeks.  I put "Mr. Tuffy" between my inner tube 
and my tire since then.  I have ridden with "Mr. Tuffy" for more than
6 months now.  I have had 3 flats.  One flat was due to a 1 inch nail 
going through the tire, "Mr. Tuffy" and my inner tube.  I felt something
bumping down the road for a little while but I did not think much of this
and decided to keep on going.  If I would have stopped I may have saved 
a flat.  The other two flats were due to cuts in my inner tube.  I do not
know if the inner tube got cut from improper mounting of the tube inside
the tire or if I hit a pothole that cut the tube on the rim.

There is one problem with "Mr. Tuffy."  It is relatively light but I 
noticed a significant difference in the acceleration of my bicycle. 
All high performance tires have very low mass.  For commuting this is
not much of a problem.  I rarely have to stop and start.
