Description Super tough. Mud ready.
EXT stands for Extreme Conditions and it's for good reason. When you want the strength and puncture resistance of the GravelKing and the ability to confidently ride through the muddiest conditions and most aggressive gravel, the Gravel King EXT is your answer.
The EXT has sides reinforced with Protite Shield technology, a bead-to-bead nylon puncture belt, resulting in a 4ply, super-tough casing.
Unique to this tire is the aggressive tread pattern, designed for the most extreme of conditions; on the roads less traveled.
Available in 700c x 33mm

Perfect for the mud I bought them for
I ran these for Landrun 2020 and they were an essential part of the kit that got me across the finish line. They cut through the Oklahoma mud, gripped well when I needed them too and didnt build up too much. Extremely happy that I ran those tires for the race and happy with the way theyve worked on non-muddy gravel roads

Good traction, but fragile in PNW mixed conditions
by Roverlord

I ran these for about 1K miles in size 38mm in a variety of conditions in the PNW, primarily Forest Service gravel and dirt roads of varying quality, plus some local dirt and root singletrack. I used them tubeless with Stan's sealant. While they provide good traction in nearly all conditions, I found the sidewalls to be pretty fragile. I had to retire them after the rear tire would no longer reliably hold air pressure after suffering many cuts that the Stan's sealant could not effectively seal. I tried gluing the worst of the cuts, but that did not help much.
If you are riding on primarily loose gravel and dirt doubletrack without rough granite or sharp shale, these may work well.
