The Coker Commuting season is over here in California, now that we’ve switched
back to standard time. It’s dark by 6pm, so I ride my bike. I had been meaning
to rotate the tire on the Coker for a while since it has two very worn areas
under and above the pedals. Last night, prepared with Geoff’s collection of big
metal tire irons, we set to work. It was a pleasant surprise. The tire is supple
and unseating one side was really easy. Better than that, the tube wasn’t at all
stuck to the tire, so the actual rotating it 90 degrees was simple. Reseating
the tire took about 15 seconds, without any tools.
This was after somewhat over 600 miles of riding - it will now probably last
until 1000 miles or so. That’s less than I expected, since I get maybe 1200
miles on a rear road bike tire, but there are only half the number of wheels.
Has anyone had to change tires yet on the Coker? How many miles did you get? I
already bought a spare from unicyclesource.com.
Also, lately I’ve been running it at 40psi instead of the recommended 32 which
feels and rides great. I commuted one-way today on it and set a new speed
record, 11.9mph average!

I’ve gotten over 1300 miles on my coker tire. Two threads of the first ply were
showing at the beginning of the UAM and by the end, the second ply of threads
were seen. The tires have 4 plys. >>
Someone told me the tire for a Coker was $100. Is that true?

I hope the commuting season wont end too soon here. I couldn’t see traveling
around campus from class to class without my coker.

I have mine at about 50 psi, and it can go up higher without any problem. Having
a higher pressure makes the ride feel a lot better!

You light wieght , I’ve been cokering after dark as long as I’ve been cokering,
its no harder. Theres all that expanse of forks to fit light too and it feels
like your going faster in the dark too.

I ride mine above the recomended PSI too, definately makes it easier, at just
32 psi the tire is kinda squidy and slugish, I think I’m on about 45/ 50 psi
at the mo.
sarah who has just been given a new front light for her coker, now its dark by
5pm and she starts work at 6pm.
I’m on my second tire, but not sure of the distance since I don’t have a cycle
computer. I’ve been doing alot of spins on the coker which of course wears out
the tire faster. I like it inflated to 50psi, had a major blowout at 58psi. The
coker is my favorite unicycle out of my collection of 19.
Check out their website ( http://www.coker.com/ ) and you’ll see that the
company is “Coker Tire” and they probably make more mony selling tires for
vintage vehicles than they do selling unicycles.
By the way, if they did decide to give away the unicycles, I’d gladly buy the
tire to go with it!
Shipping the coker tire is expensive. I bought a replacement tire and tube +
shipping for $75 dollars. The guy at coker was nice enough to ship the coker
tire NOT in a box, saving some bux. The UPS person said she never saw something
shipped quite like that…
The tube arrived seperately
I still havent put the new tire on… Today on the way home I tried to hop a
curb (while carrying hamburger fries and drink) and the uni dropped. The
pedal is now bent really bad. How the heck am I going to get to work
tomorrow…? errrgggg
Chris Carey Anaheim CA Lost my car, have to ride the coker 8 miles to work, 8
miles home

I tried overinflating my Coker as well, but the bead would not stay in the rim
on one side, exposing the tube at which point I quickly deflated the tire. Every
attempt at seating the tire at 40-50 psi failed in exactly this way. So, I’ve
been sticking with 32 psi which works great!
The road riding is much smoother at lower psi anyway. Also, MUNI riding at lower
psi reduces the jolt of bumps much better than higher psi.
For those that overinflate the Coker tire: Setting the bead on a larger diameter
tire is tricky. An overinflated (50 psi) Coker tire bead could slip off the rim,
blow your tube, and injure the rider as well. Hopefully, you will be going less
than 20 mph when this happens and can jump safely to the ground, possibly
rolling into ball as well.
Has anyone else had a problem keeping the Coker tire seated at 50 psi? I’ve just
now considered applying glue or a slip resistant compound to the inside of the
rim. Has anyone tried that?
