Featuring a shallow, micro-textured centreline for impressively low rolling-resistance, this pacy effort does not shirk when it comes to confident and composed riding. Keeping you upright through corners are well-spaced shoulder lugs which cling to whatever is available to keep you upright and in control. Well-protected by its 120 TPI Nylon casing and integrated PPS Puncture Protection Strip, as well as its Vulcanised finish, not much will deter this tyre from rolling you to new levels of gravel-grinding excellence. Coming complete with a fast-rolling diamond centre, this tyre is perfect for all-around gravel and adventure riding.

Technologies:
Vulcanized Tubeless Ready (VTR): The highest level of performance offered by car, truck and motorcycle tyre manufacturers is a vulcanized tubeless system. While this is an old technology for cars and trucks, for bicycles it is relatively new and did not even have an internationally accepted design standard (ISO or ETRTO) until recent years. By eliminating the inner tube it is possible to lower the weight and create a softer, more comfortable, more efficient, lower rolling resistance tyre system by running lower tyre pressure. Challenge started introducing Vulcanized Tubeless Ready (VTR) tyres in recent years because the ISO and ETRTO standards for proper VTR tire and rim fit have finally been completed. These standards ensure your safety and your ability to fit and service the tyres with hand tools.

Challenge Gravel Grinder Tubeless Vulcanised Tyre is rated 1.8 out of 5 by 5.
Rated 2 out of 5 by Jb9981 from Roll quickly These roll well, but have had issues with the tread wobbling as spin the wheel (looks like it is out of true).

Rated 3 out of 5 by xap85 from They're 'ok'...for the right conditions. Have used these 42c gg tyres for a couple of months now. They're 493g on the kitchen scales and come up at 44.5mm wide on an internal rim of 20mm-so check your clearances. Positives are the comfort provided by running them tubeless at lower pressures and the increased width. They roll well on tarmac, hardpack and dry off road conditions. They are not designed for muddy, wet off road conditions. On the negative side I would agree with other reviews about the robustness of this tyre-the side walls do appear a bit thin and I wonder if this is why the come up so wide on the rims? I've had plenty of punctures, known and unknown, but no catastrophic failures. I swear by the Orange endurance sealant, which works wonders with plugging holes from sharp thorns etc.

Rated 1 out of 5 by Lansbury67 from Side wall pants The first tyre that a hole in the side wall, would not seal on the wheel. The second went on all ok. First ride out and a large split on the side wall. Tried to fix out on the ride, no luck. Wife’s not happy as the rest of the sealant is now in her car. WOULD NEVER buy this make of tyre again.

Rated 2 out of 5 by Boxrick from Overweight, slippy, puncture easily and expensive I purchased a set of these tyres to go on my gravel bike. The 38mm version came in around 440g, well above the advertised 380g. When I was using them they were slippy on both on and offroad surfaces and the nobbles began to wear fast. I then purchased a set of Gravelking SK 38 at 1/2 the cost, roll much nicer, much more grippy on road and gravel surfaces. Save your money and get a better tyre for less!
