Prompted by this thread I changed out the Rolly Poly/Ruffy Tuffy front/rear
combo on my road bike wheels to the pair of (what I have considered to
be special event) Grand Bois Cerf 28mm tires. I rode them for 25 mountainy
miles yesterday and enjoyed their feel immensely. Today I got a front
goathead flat. This is the 3rd flat I have had on these tires in about a
dozen rides. This is by far the worst flat record of any tire I have used,
ever. I understand I cannot say this will be the flat record for me in the
future or for you in your environment, but my faith in the tire is shaken
and it affects the enjoyment of my ride. I am putting more effort into
scanning the road or trying to stay off the dirtier portions of the road
instead of enjoying the view or thinking my deep thoughts. {~;

When I got home I fixed the flat, pulled the GB Cerfs and replaced them
with the RP/RT combo. As I was changing them, I weighed them on my Park
digital spring scale. To the nearest ounce, the Cerf was 10oz, Rolly
Poly 11oz, Ruffy Tuffy 13oz, Jack Brown Green 33mm was 12-13oz. All of
these tires are made by Panasonic. Now I believe Jan Heine's rollout tire
comparisons are valid. But for me to flat every second or third ride is
just not worth the lower rolling resistance or an ounce or two of rotating
weight.
