Feel Like A Winner With This Race Day Tire

When your bike's tires seem to be wearing a little thin, you know it's time to upgrade. No matter if you prefer gravel or dirt, the Panaracer GravelKing SS is the ultimate race day tire. With durable construction and the power to crush through long miles of gravel, you'll be on a whole new level with these 650b tires.

The SS features an all-new tread pattern consisting of a smoother, diamond pattern center with more aggressive side lugs. This tread pattern allows the rider to keep the speed going into corners and maintain control throughout any transition a gravel ride could present. The GravelKing SS incorporates a supple 126 TPI casing with a nylon puncture-resistant belt and Panaracer's proprietary ZSG (Zero Slip Grip) compound. For those extra demanding courses or rides with sharp flint rock, the SS is the tire for you.

Make the most of your next race day with the Panaracer GravelKing SS 650b Tire for any of your dryer gravel and dirt needs. Featuring advanced extra alpha cord protection on the casting, this construction allows for a winning ride every time.

    Super Leaky, lots of punctures

    One of these tires is working ok, the other one is constantly slow leaking and wont hold pressure overnight... a spray bottle of water shows small bubbles coming out all over the tread of the tire... no amount of sealant will stop it. Now I've gotten two punctures right in the center of the tread that sealant was unable to seal... so going to look for an alternative.

    Stiff yet fragile

    Bought these because I wanted a fast Groad tire with enough volume to handle some fast descending over the rough stuff.

    Very stiff side walls take away corning feel and make for a rough ride until you drop the pressure down to nearly 20psi.

    2nd ride out, on a well maintained almost 2 lane gravel road, I hit something and ended up with a slice as wide as my finger plus a second hole near the bead.

    Incredibly disappointing.
