Description of Challenge Gravel Grinder TLR Folding Tire - 33-622 - black / brown

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.

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.

been riding for 1 year and had no problems with them.The comfort is astonishing, theyare fast on dry roads §sandy or hardpack), less suitable for mud.

Easy to mount and keep the pressure well enough.
Die Reifen laufen richtig gut und sind komfortabel. Tubeless Montage lief unauffällig und gut
Sidewalls full of holes. Not possible to make it tubeless.
