The Panaracer GravelKing Tire is designed for cyclists who are looking to expand their cycling horizons. While smooth, pristine asphalt may be nice, but some of the best views can only be found via gravel. Panaracer's 650b GravelKing tire solves that problem. Featuring a natural rubber compound, puncture protection breaker, and a special tubeless ready low rolling resistance casing, the GravelKing is truly a go-anywhere tire.

The Panaracer GravelKing 650b tire is available in multiple widths: 38mm, 42mm and 48mm. Black or brown sidewalls.

Great ride!

Panaracer GravelKing tires reliably provide a great supple ride quality with good road traction. I use these primarily for commuting through a city and haven't had too many issues with flats or punctures. My go to tires!

Comfortable and fast

I've been using Gravel Kings on my daily commuter for the past three months and these tires have encouraged me to extend my commute to work and home since I'm having too much fun riding my route.

The roads here in Houston are heavily pockmarked with potholes and these tires handle them with no problems and just roll over them without any tremendous jarring feeling. On pavement, they roll fast and grip corners well. They're also a blast to use in fine gravel, they float and move quickly and sure-footed.

I'm currently using them with tubes and on 40 psi front, 45 psi rear and have had two punctures on the rear tire. First one due to a nail, the other due to a construction staple.

Smooth ride

I just got these and did my first ride last night. I got them for my 3T for a set of winter tires. Road on a newly refinished road with chip seal and they are smooth. Took a few tries to get them to seat on my rims but i think that is the rims since i had the same type of problem with the schawlbe that i had on the rim.
