I have alot of envy for the Schwalbe Marathon crowd, with their thornproof extra layer of protection. A premium 120tpi fatbike tire has no such protection; something I guess that is so because these tires are made to run anywhere from 30 psi down to single digits in snow and sand conditions. And for that to happen in low pressure, the side wall and the tread has to be pliable and flexible to match the terrain.
You learn pretty quick what needs to be done in fixing a roadside flat: remove handlebar bag, LCD display; rear bag(s), put rear cassette gear in highest gear (smallest sprocket); shift front chain ring to granny gear, disconnect rear rack (not pictured here) from rear thru axle. Find a shady spot, preferably grass. Put towel under saddle to prevent wear of seat cushion. Watch for ticks....
Alot of grief over that little white dot, which turned out to be a quarter inch thorn I picked up on the shoulder of the road. An asphalt shoulder. And that tiny thorn also pierced the Mr Tuffy Liner that I was using on at this time. In my thousands of miles riding first a Specialized Fatboy, then this Haibike, those little white dots have been the cause for a lot of grief on my rides.
March, 2019 and another 1/4 inch thorn did me in, I had enough. I went tubeless! Bought the flashing tape to tape up the underside of the rim. Bought the Orange Seal Sub Zero. Special tubeless tire valves. Bought the fancy, expensive Dyna Plug plugging kit, pictured above, along with extra plugs. The tubeless gunk inside the tire is supposed to take care of the tiny thorns (which they did). For larger holes, the Dyna Plug comes into play. But I found out in summer of that year that the Dyna Plug cannot fill a gash in the tire tread. Well, I made it work, stuffing all of the extra Dyna Plugs I carried with me, along with a 10 mph max speed that somehow got me home. The tubeless experiment went on until July of 2020 when another tire gash convinced me tubeless is not right for me. Tip of the day: When your tubeless tire explodes (yes, that happened to me, too), it's best to quickly wipe up ALL of the sealant on the bike, underside of the rack, saddle, all those small areas where dirt collects; that's where the sealant goes, too. And when it dries, it's a bear to get off. Ask me how I know this, too!
Tannus Armour was ramping up when I went all-in with their tire liner system. I was skeptical, especially after looking at the small tube they include with their fat tire liner system. But, it does work...
October 2020 had another roadside flat repair as a 1/4 inch thorn pierced the rear tire, T/A and pricked the tube ever so slightly. As the tire was going flat, I remembered the Tannus boast of riding on the flat with that liner. Maybe so with a small 700c tire but certainly not with a fatbike tire. I did not want to risk bending the rims, so I just pulled over and went about patching the tube. These fat tires look cool and all. They move easily and roll very nice. But their profile presents over 75% of tire contact patch more than what the commuter crowd shows with their contact patch. The odds are so much greater to get flattened out. But you do build up those tire patching and fixing skills.
That flat in October 2020 was the last flat I've gotten on the Haibike Full FatSix. I estimate some 5 thousand miles later on that rear tire, we come to this, a severely worn rear flat tire that was replaced with a new Schwalbe Jumbo Jim in December, 2021. That is a personal record for me and still am floored that actually happened.The trick to this longevity? What alot of you folks have figured out: staying mindful of the debris in the shoulders in which you ride in. Riding more on the white line when it is safe to do so. Taking care when riding off road to avoid dropped small tree branches, especially thorny locust trees. Not going off trail, where alot of thorny plants reside. And a ton of luck. Especially that!
