Description of Challenge Gravel Grinder TLR Folding Tire - 42-622 - black/black

This Tubeless Ready all around gravel tire is designed for long rides over gravel roads. Thanks to the Puncture Protection System it is also suitable for a rougher everyday use. The flat tread in the middle keeps the rolling resistance low while the higher side knobs offer the needed cornering grip.

This folding tire with a 120 TPI casing made of nylon is very supple and comes with a Puncture Protection Strip (PPS), which is an extra layer of highly resistant material between the casing and the tire to reduce the risk of punctures.
Weight supplement: 38-622 | manufacturer information)

Note: Tubeless Ready tires require tubeless compatible rims/wheels, tubeless valves, tubeless rim tape and sealing fluid for tubeless mounting. Sealant fluid is not required for tubeless UST tires, but is recommended for increased puncture protection. Installation should only be carried out by qualified personnel.

I had the same sealing problem but only for a few days. I used Continental Revo Sealant, rotated the wheel on its sides for a day and it sealed perfectly. I've heard that Panaracer sealant is also good for porous sidewalls.
My problem is, that after a year a few bubbles formed under the tread. Now I'll throw them in the trash as I think it might be dangerous to ride this way.
While it was working well I really liked these tires. Excellent grip, low rolling resistance and very comfortable (42-622).

Неожиданно плохо. Unexpectedly bad.
Покрышку не удаётся заклеить.Давление быстро падает.Всё время появляются маленькие отверстия на боковой поверхности покрышки.
Stan's NoTubes Rim Tape,Squirt Seal Tire Sealant 100ml,LifeLine Universal Tubeless Presta Valves.Моя вторая покрышка Challenge Gravel только 38-622 имеет такую же проблему! Почитал отзывы в интернете-у всех одинаковая проблема!The tire fails to glue. The pressure drops quickly. Small holes appear on the side of the tire all the time. Stan's NoTubes Rim Tape, Squirt Seal Tire Sealant 100ml, LifeLine Universal Tubeless Presta Valves. My second Challenge Gravel tire only 38-622 has the same problem! I read reviews on the Internet, everyone has the same problem!

Leider bei mir das gleiche Problem wie bereits bei der 38mm Version hier zu lesen: Die Reifenflanken sind nicht dicht (mit Schwalbe Doc Blue und Stans NoTubes) und verlieren schleichend Luft. Im Wasserbad sieht man die Bläschen. Nutzt man die 4 Bar Maximaldruck aus, kommt es sogar zu kleinen Platzern in der Karkasse. Schade, retour angefordert.

Bike24: Wir bedauern die Schwierigkeiten mit dem Produkt sehr. Nehmen Sie bitte Kontakt mit unserem Kundenservice auf, wenn Sie das Produkt bei Bike24 erworben haben. Das Service-Team von Bike24 ist Ihr Partner auf dem Weg zu einer zufriedenstellenden und nachhaltigen Lösung.

unbedingt probieren.
Seit Conti den Speed King in 45 E.T.R.T.O. aus dem Programm genommen hat, ist das für mich DER Reifen, der auf Asphalt läuft, wie Lottchen, im Gelände ausreichend Grip bietet und mit seinem geringen Gewicht - vor allem tubeless - ausgezeichnetes Handling bietet. Wer ihn in seinen Rahmen bekommt, sollte es mit diesem Reifen ruhig mal ne Nummer breiter probieren.
