Panaracer Gravel King SK TLC Folding Tyre - 700c

Aggressive knobs, natural rubber compound, puncture protection breaker and a special low rolling resistance casing make the Gravelking a go-anywhere tyre.

  • Aramid beading for durability
  • Low rolling resistance casing
  • Weight: Approx. 380g
  • Tubeless Compatible
Impressed with these tyres, roll nicely, grip well and look very cool indeed in their skinwall form. Easy to fit and responsibly puncture proof too. Perfect for a classy gravel bike.
Great grippy tyre with a lot of bang for your bucks. Ideal tyre for mixed rides (gravel, cross, pavement, etc). Although it doesn't have much offroad profile, traction is still good on dry offroad stretches. Great tyre. Great service from Merlin to! Quick dispatch and (international) delivery.
Bought a pair of Gravel King 43mm. Absolutely love these tires - super comfortable, and they look great. Bigger is just better!
Amazing tyres! Grippy and fast rolling. Some experience is required when mounting because it's tight but once you put it on you'll be happy with it's performance and look. I ordered the 'brown' and I like it!
Excellent tyres. Roll fast on road, corner well and great traction in the dirt. Run tubeless at 35-40psi.
Lightweight, great colour and superb performance.
Great dry CX or gravel tyres, good on road too - fitting was easy and set up tubeless first time - very pleased
Superb product, highly reccommended for gravel and they are fast on road.
Look awesome in the tan wall, and also sealed up easily running tubeless
Well made and super tough tyre. Have bashed it over sandstone, gravel, rock drops and gutters. I run it tubeless and it's been bullet proof! Rolls well with lots of small knobs in the middle and heaps of grip in corners (I have it on the front). About to buy another one!
Took few minutes to setup as tubeless. Really enjoyed my first ride on these gravel tires.
43 mm's are excellent so far. No tools needed for mounting! Running tubeless low pressure on Hunt wheels without any problem.
Seem really good. Roll great on road and been good on trails/gravel. Would recommend
Very bulky, low rolling resistance, very easy to mount on rims.
I believe Gravel King SKs are the best tyre for mixed on/off use and super on everything except mud (which they collect excessively). Sizing has been revised so that the purchased "38" is actually 38mm mounted, and it weighs about 450gm. This contrasts with "40" SKs bought a year ago which measured 43mm mounted and weighed 495gm - the same tyres now listed as "42" I expect.
Ordered the 32 mm black/brown ones and they look and feel amazing, pretty robust yet comfortable. Set them up tubeless, my first! Was a bit worried but pretty straight forward to sit them on the wheels on the first go, no leaks! Absolutely love it!
Great tyre, setup as tubeless which panaracer say is fine up to 55 psi.. Bit of a faff, but inflated with a tube first to get them to pop onto the rim, then removed the tube and added sealant, used a Co2 to inflate.. been fine ever since.
Very resistant tyre for hard surface !
Mounted tubeless quite easily on the Hunt wheels I purchased. Took a week or so to seal which isn't too bad. Faster on tarmac than I expected and really good on everything else, except for thicker mud which is understandable given the tread pattern. Used for commuting on bike paths and weekend rides on fire trails and gravel roads. Definitely recommend!
Great tyre. No problem with setting it tubless.
Set these up tubeless on my gravel / CX bike. Only used on road so far (commuting) but seem to be fairly smooth running and grippy on road (for a gravel tyre) on road. Set up tubeless was easy - seated straight away using Airshot tank.
For some reason one tire went on easy, the other was a royal pain. But they roll good on pavement for a gravel tire, though my previous tires were Clement MXP's. Only ridden on dry dirt and gravel so far and they're fantastic. Based on minimal tread, Mud will be probably not be so good. Not why I bought them though.
Superb gravel tyres. Plenty of grip and the brown wall version looks mint on my Mason Bokeh
Tightest beads I can remember in years; I guess this should reassure most above and beyond the added hassle of fitting. Sidewalls not as supple as the tyres they make for Soma, Compass, etc. - this is the only disappointment, although I guess their partner companies would be pretty pissed if they were selling equivalent tyres at almost half the price. On a positive, there's no leakage, personally i'd rather suffer adding extra sealant and the faff that comes with it. Come up to size and weight as per manufacturer claims
Easy to fit, seem like a good balance of knobs and tread for both road and gravel. Roll on the road OK and on hard packed gravel OK as well. Have not tried on loose gravel or mud yet.
Excellent tyre! Used it in 38c for a 150 km long gravel, trail and mud race and it was really good on all the gravel parts and even gave me some grip in the mud. And no punctures :)
The Gravel King 700x43mm have proven to be a great purchase. Offered at a very competitive price and delivered promptly by Merlin, they've been on the bike for just over a week now. Set up tubeless, they were a tight squeeze to get on my Hope Tech XC rims. Out of interest I tried to seal the beads with a regular track pump, but couldn't. However, using the Bontrager Flash Charger they sealed first time and, other than dropping from around 40psi to 30-35psi after the first couple of rides, have held their pressure. They roll really well and reasonably quietly on tarmac and metal roads and, in my opinion, inspire more confidence than wider, chunkier pair of tyres (Nano 2.1") on my gravel bike which is used primarily on tarmac, metal roads, sustrans routes and only very occasionally anything that could be classed a trail. Other reviews I've read indicate that durability will be as good as many other tyres. I'm seriously considering the 35mm version of these for the cross bike. My opinion is highly favourable. My only complaint is that I couldn't get them with the tan sidewalls!
Really happy with these tires. I ride on a mix of gravel and paved roads and they roll very well on both. The handling on gravel is secure and well footed. Big test will be how resistant they are to punctures, which was the main reason I switched. But they seem more rugged than the previous tires I was using.
Great tyres have them on two bikes now and great service from Merlin
I am running these as tubeless and they took several days to seal, but have since worked flawlessly. I have ridden them mostly on a mixture of pavement and gravel roads and I have been very impressed at the low rolling resistance and relative comfort. I have also used them on single track, but grip in the wet is poor and generally it is not a good idea. After about 500 km they are showing little wear so i am hopeful that they will last. Nil punctures so far.
The best gravel tyres in the market
First foray into gravel tubeless tires...easy to set up, tread pattern perfect for on/off road jaunts and just the right width.
Great product fast rolling on road super grip in sketchy surfaces.
Decent tires all round, bit fiddly to get on to start but once on they work well. Not bomb proof against punctures.
Great tyres for mixed gravel and road rides. Low rolling resistance and do well on hard pack and light sand.
Great tyre to go on my crosser for a bit of gravel grinding. Went on easily with no need for anything other than my standard track pump & some soapy water.
Brilliant all rounder. Rolls surprisingly well on road but copes with rough off road
Great tire, I think this is the best in category. A good casing and uses a really great compound.
Can`t believe the difference between these and 32c tyres... They just fit my CX bike with a couple of mm to spare... ride quality is so much better... smooth...takes the bumps well.. still keep up with the roadies ... and no pinch flats.
The tires work as promised. Great grip on all types of gravel and low rolling resistance on the pavement.
Gravel King is a good name for these puppies. While many brands 40C gravel tyres run small, these run a tad large and measured 42mm on Hed Ardennes -- making them in truth more than 5mm wider than WTB Nanos. Given this the 475gm (measured) weight isn't so bad. They fit -- and nearly max out -- the rear clearance on my Kinesis ATR perfectly, and do the job on dry dirt sand and pebble surfaces. Have not tried mud yet but they should be OK. No problems with the tubeless seal either. Solid product.
I purchased these tyres to use for some riding on unsealed roads on my CX bike. If I'm honest the 32mm tyre doesn't offer a whole lot in terms of ride comfort nor are they confidence inspiring on the loose stuff. I'd probably go for the 40mm option if I had my time again.
Huge air chamber, meassures 43mm on DT460db rims (17mm internal). Can be ridden safely as low as 2.2bars, in the woods I would probably go upwards 2.8 or 3 bars to keep the tyre on the rims. Easiest tyre ever to seal tubelss ever: I've tried tubeless ready MTB tyres from Michelin, Geax and Schwalbe + 35mm Compass road tires. Grip: like glue on wet and slippery autumn surfaces. Rolling resistance - not as low as on my 35mm Compass with exralight casing though. You won`t notice the diference between a herringbone thread and this SK on pavement. I doubt that Schwalbes more expensive G-ones can compete. Casing is really subtle and comparable to Vittoria`s Pave open and Pave tubular. Weight: heavy due to the size. Affects acceleration but when setup tubeless you`re not far from a Compass or 32mm Gravelking with butyl tubes. Still lighter that a pair of +30mm Gatorskin, Durano's or Paelsa's. Cost: dirt cheap for a tire this quality - that would cover all gravelking from the skinny slick 23mm throughout the range. Durability: so far no punctures, based on my experience with compass tires suing same compound I'd say they will be really hard to wear out or puncture. Wind resistance: probably the only drawback - but that`s unavoidable for a tire this size. It can really be felt in headwind or when exceeding 30-35km/h. Merlin. please carry the slick 26, 28 and 32mm editions. This new pannaracer range is unbelievable in regards to rolling resistance smoothness, grip, durability and cost - while still keeping close to the weight of a top end clincher/tubless. And they are a hell of lot lighter than Swchwalbes less durable S-one / G-one range. The 23-32 slicks are identical to Compass's non-extralights.
