Get grinding.

Reinforced for long grinds down bumpy gravel roads, the Panaracer GravelKing 650b Tire features an Anti-Flat Casing that prevents inconvenient flats when you're a long way from help. This version of the GravelKing satisfies the needs of 650b gravel bikes and touring rigs gaining popularity with riders seeking agility and increased stand-over.

The grippy tread pattern inspires confidence across the jarring surfaces and loose rubble common to gravel stretches and off-road stretches. ZSG Natural Compound balances a low rolling resistance with tread longevity, giving you the best in efficiency and durability along mixed gravel and asphalt surfaces, seeing you'll encounter both on adventurous tours and everyday gravel grinds. Please note, this isn't the best tire for mucky conditions, as Panaracer developed a mud-specific version of this tire for sloppy muck.

Unanswered Question

Referring specifically to the 650b 42mm black option, are these tubeless tires? The photo only shows “TLC” on the brown sidewall, and the description only lists clincher, but a previous answered question and the Panaracer website suggests they are able to be used tubeless. Thanks!

Is this really the 42mm or the 48mm? I haven't been able to find the 650bx42mm sk anywhere.

Yes, it is all of our measurements are given by the producer and are accurate.

Shows pics of a slick and one with knobs... assuming the correct one listed is the knobby version?

Hey, This is the tire with Knobs. I am sorry, the slick photo is incorrect.

The write up / description/ buying options are not consistent. Is this a 650B or 650C? They are quite different.
