PANARACER GravelKing SS 650B × 48 Tyre – ZSG Natural, AX-α, Tubeless Compatible, Black/Brown (RF650B48-GKSS-D)

PANARACER GravelKing SS 650B × 48 Black/Brown is a fast gravel tyre featuring a semi-slick tread pattern that blends efficient rolling on tarmac with confidence on gravel and hardpack roads. It is ideal for spirited gravel rides, endurance outings, and race use on mostly dry surfaces.

The combination of a micro-diamond centre tread, more pronounced shoulder knobs, compliant AX-α Advanced Extra Alpha Cord casing, and Anti-Flat Casing puncture protection offers a balanced blend of speed, comfort, and durability. The tasteful black tread with brown sidewalls gives any bike a classic gravel aesthetic.

GravelKing SS – fast semi-slick tread design

The SS (Semi-Slick) designation defines a tread design featuring a low-profile centre tread combined with more pronounced cornering knobs.

The central diamond-textured section promotes minimal rolling resistance and quick acceleration on pavement, hardpack gravel, and smooth dirt tracks.

Side knobs provide grip through corners, helping to maintain full control when leaning on unpaved surfaces.

This tyre is best suited to dry and firm courses. For deep mud or very loose ground, a tyre with a more aggressive tread is recommended.

ZSG Natural Compound – speed and grip

The ZSG Natural Compound (Zero Slip Grip) rubber compound is engineered for low rolling resistance, reliable grip, and solid tread life.

It sustains high rolling speeds on tarmac while delivering dependable traction over gravel and packed field paths.

AX-α Advanced Extra Alpha Cord – supple casing construction

AX-α Advanced Extra Alpha Cord technology employs fine, highly dense cords woven into the tyre casing.

This build enhances suppleness, lowers overall weight, and absorbs surface chatter. The tyre conforms effortlessly to the ground, resulting in a smooth, fatigue-reducing ride feel over long distances.

Anti-Flat Casing – dependable puncture protection

The Anti-Flat Casing reinforcement layer shields against punctures and sidewall cuts caused by small, sharp debris and stones.

It is specifically engineered to raise durability across gravel trails without sacrificing casing compliance.

48 mm width for comfort and stability

The 650B × 48 (ETRTO 48-584) size corresponds to a 27.5" wheel diameter with an approximate width of 1.90".

A high air volume tyre allows riders to run lower pressures to damp vibration and chatter effectively. The 48 mm width brings stability, comfort, and secure bike handling on coarse gravel and broken roads.

Always verify rim compatibility and adequate frame/fork clearance before fitting.

Tubeless Compatible – tubeless-ready operation

Engineered with a Tubeless Compatible design, this tyre supports tubeless setups when combined with a tubeless rim, valve, and liquid sealant.

Tubeless setups seal small punctures instantly and permit fine-tuning air pressure according to terrain and load.

The tyre can also be run with a standard inner tube if desired.

Maximum pressure is 350 kPa, approx. 3.5 bar / 50 PSI. Always observe the pressure limits specified by your rim manufacturer.

Folding bead and classic styling

Equipped with a folding bead, the tyre is lightweight and easy to install, store, or pack as a spare.

A weight of approximately 540 g represents a well-balanced compromise between volume, comfort, and protection.

The Black/Brown colourway pairs a black contact surface with brown sidewalls, perfectly complementing both vintage and modern gravel builds.
