Hallo,

benutzt jemand von Euch die GreenTyres Schaumstoffreifen? Diese sollen
den Vorteil haben, absolut pannensicher zu sein, da kein Mantel/Schlauch
etc. Ich wuerde aus begreiflichen Gruenden (ueberall Glassplitter auf
Radwegen) sowas gerne an mein Stadtrad machen. Kevlareinlagen sind
sicherlich eine Alternative, aber das Prinzip von diesen Reifen finde
ich ganz interessant, hab nur noch keinen Haendler gefunden.

Gruss,
Adrian


Hier Auszuege aus einem r.b. Posting ueber diese Reifen:

>Anyway, these tyres are supposed to offer:-
>
>Freedom from punctures.
>Ride comfort (as normal tyre).
>Light weight (c. 60% of a normal tyre + tube).
>Long life (3-4 times the life of a normal tyre).
>Good price (same as a normal tyre + tube).
>Can be made in various (apparent) pressures.
>Made from a single synthetic rubber (hi-density foam), no CFC's
>and can easily be recycled.
>
[...]
>So on with the review:
>
>Appearance:
>
>     They look just like a normal road tyre.  Low profile
>     tread.  There are two nylon cords embedded in the base
>     of the tyre wall.  (Where the steel bands are in a normal
>     tyre.)
>
>Fitting:
>
>     The tyres are about 10% undersized.  That meant that my
>     27" tyres had an internal diameter of about 24 1/2".
>     I was convinced that I'd been sent the wrong tyres and
>     just could not get them over the rims of my wheels.

>     I was then shown how to fit them by a GreenTyres expert
>     (one of the company directors happened to be in my area
>     for a meeting and called in to my house on his way home!)
>
>     The technique is to first give them a good stretch with
>     your feet and hands (heave! - and keep that back straight!)
>
>     Then hold them to the rims with a couple of tie-wraps and then
>     lever the tyres into place.  No special tools needed  (but
>     a plastic mixing spoon or spatula is a good lever).  Takes
>     about 3 mins when you have the knack!

>In Use:
>
>     The Green Courier is a road/racing tyre and so has an
>     "apparent pressure" of about 100psi.  
>
>     We (my wife and I) have now been about 30 miles each
>     on our new tyres (hay fever was acting up, so I couldn't
>     go too far).  I really couldn't tell the difference between
>     these tyres and my normal ones.  (I'm not good enough
>     a cyclist to really notice the 6oz weight saving on each
>     wheel.)
>
>     No problems with overheating, rolling resistance or anything
>     else.  We rode over various surfaces including sticky tarmac
>     and new granite chippings.  No problems at all.

>Conclusion:

>     Freedom from punctures and more importantly not having to
>     blow my tyres up before riding are quite important to me.
>
>     Now I can have that and weight reduction and longer life.

>     Got to be worth a try!
