Tyre pattern direction

i changed my tyres around once, and accidentally put the tyre on
backwards.

the tread wore out more in 2 weeks with little riding than it did with
3 months of lots of riding.

change it over ASAP. i wish i had

i know people, contrary to the previous post, who run their tires
backwards on purpose, because it supposedly gives 'more traction' on
one wheel.

I have no evidence to support that, as i really don't check to see if
my tires on backwards or not.
i just ride it.

Well, more traction would mean it would wear faster, wouldn't it?

I'm just thinking if it's worth it taking it off and putting it on
again, as it is a 3" tyre and when I was putting it on I bent a spoon.
I'm afraid I'll bend my rim if I take it off.

it will wear the same no matter wich way you put it on. putting it on
the recomended way will give better grip under decell (braking),
running it backwards will give you more grip under power (uphill).

Tires are designed to shed mud out of the tread while, rolling unis
don't go fast enough for this to work. Most biketrials riders, will run
the tires backwards for better grip against sliding backwards down
obstacles. The same applies to muni.

edit: you won't bend your rim. Buy good tire levers anyway, michelin's
are my fav.

So it doesn't really matter which way for street/trials and casual

running the tyre backwards will wear it down faster. i'm not gunna go
off all the technical stuff that it gives more grip uphill backwards
and what they're designed to do and all that rubbish.

i know from experience, it wore down more in 2 weeks when it was
backwards than 3 months when it was forwards.

Was it the same tyre as you normally use and were you riding the normal
amount and doing the usual tricks?

I've had it like that for about 5 weeks and it's only worn out in
places where I hop. And I ride about 4 hours a day on the average.(and
half of that time I hop). I'm kind of afraid to take it off, cause I
might damage the rim. Maybe it's just for your tyre? What tyre do you
have?

When I first read your post I was like "OOOOOOHHHHH" and ran to take
off the tyre, but only got as far as taking off the frame.

10+ years of unicycling experience (8+ muni) tells me you don't know
what you're talking about. tire pressure and ruber compound, and
terrain make way more difference in tire life than direction.

Ivan leave your tire alone unless you find you need to maximze
downhill grip. you want it backwards for trials/street you'll get more
grip when you up/gap to something and just catch the edge.

10 seconds to read a post tells me you're a jerk.

i know what i'm talking about, i build bikes and unicycles as a hobby.

you can have all the experience you want mucking about on a unicycle,
but when i've lost 1.5mm of tread in 3 months of riding, which included
learning on it, riding muni and mainly road for loads of km's, and then
when i accidentally put the tyre on backwards one day, and less than 3
weeks later i've worn down 2mm of tread, i think i know what's going
on. in that time period i rode it a lot, lot less and kept the tyre
pressure the usual.

now, i know you're not a rocket scientist (it's pretty damn obvious),
but if i lose 1.5mm in 3 months with it forwards, and 2mm in 3 weeks
with it backwards, one could pretty accuratly say that it was because
of tyre rotation.

second point.

do you think they put the arrow there just for the heck of it? it must
have some advantage in going the way it was design for. Sure it may
give you more traction going up a hill with it backwards, but what
about when you go down the hill? Uni's need grip to go forward, but at
some point they slow down and need grip there too.

well, i think we've now firmly established that my tread has worn down
due to it being backwards. unless of course your 10 years of unicycling
experience (which no doubt is much more impressive than any of the
experiences i've had in my lifetime) can haul it's [censored] over to my
garage, and show me why my tread wore down not because it was
backwards.

uh yeah dude, i don't know if you realize but these tires where built
for downhill bikes. they are built to grip when the bike is leaned out
on corners. they are designed to shed mud so they stay gripy. unicycles
put different stresses on tires than a bike, much slower (duh) and no
leaning over (duh). the arrow is totally irrelevant to unicyclists.

loads of road km's on your dh tire is the dumbest thing i've ever

I have enough tires in my garage thanks

I put my CC on backwards, from the original direction it was at when I
got it, and this was probably caused by the really thick tube that I
used, I dont think it fully expanded to fit the tire.

Anyways, after I got the tire on, I noticed it to be hard to ride, I
got that one thing I hear everyone talk about, mainly on 28 and 29ers,
where the uni pulls to the left or right, and it really sucked, but
after riding on the tire for about an hour, it goes away, but its
always showed up when I rode it for the first 3 days, now I am pretty
sure its gone, and I am used to it.

I do know on some, actually, most tires, the tread faces a direction,
which makes it easier to roll with that direction, having it on
backwards adds more traction and pulling issues on pavement, but when
jumping and on dirt, it will help.

I am not sure about it wearing out more, I guess it could happen on
some tires, guess you gotta get lucky, or unlucky. one of those works.

Maybe I should just put the whole wheel on backwards. That way I
wouldn't have to actually take the tyre off. I would tighten the pedals
once a week or so to make sure they stay tight. That'd be much easier
than messing with the tyre.

loads of road km's on your dh tire is the dumbest thing i've ever
heard. You're worried about tread life?

i'll calm down in my own time thankyou, i don't need somebody who i
don't know who lives on the ohter side of the world to tell me what to
do with my emotions.

wow you've been doing custom fabrication on rally cars professionally
for a few years? that's just so relevant to the topic.

loads of road km's on my dh tire is the dumbest thing you've ever

you musn't hear much.

dumb would be me every time i want to ride on the road changing my
tyre. i'd have to change it every 2 days. i'd rather ride my dh tyre
than spend all that time switchting tyres thankyou.

what do you mean unicycles don't lean over? i lean over on my unicycle
for turns all the time.

i originally said that from my experience, that riding with the tyre on
backwards wears down the tread faster.

you disagreed and said that because you've been such a hot-shot
unicycle rider for so long that i don't know what i'm talking about.

i don't know what you're on about, like seriously?
are you trying to impress me with all these figures and job's you've
told me about?

when i ride a tyre for 3 months and get 1.5mm of tread worn off, and
when i ride that same tyre backwards for 3 weeks and get 2mm of tread
wear, i think it's fair enough to say that it was because it was
backwards. surely, you don't need experience to tell you that?

Putting the wheel in backwards will mean the pedals will come loose
despite regular tightening and will try to fall out at the worst moment
also riding with the pedals the slightest bit loose totally kills
cranks and rips out the thread.

If you want to put the wheel in backwards you will have to pull off the
cranks and swap them round, which is probably more work than just
pulling the tire off

I'd disagree with what you're saying here completely, faster riders do
ride fast enough for the mud shedding properties of the tyre to be
useful. They also lean over to rail corners on downhills in a similar
way to bike riders. If you're just doing trials, then maybe not, but
muni riding certainly uses the tyres in a much more similar way to a
bike than you're suggesting.

Also, different tyres have very different tread designs, so you can't
make sweeping generalisations about running them backwards. For example
some tyres (IRC make some like this) are designed to be run one
direction on the front for braking, and one direction on the back for
acceleration. With tyres with a single direction on them, what you get
or lose by running them backwards basically depends on what they're
designed for primarily.

It's also pretty obvious that if running the tyre backwards affects the
way in which the tyre rides, it must be affecting the way in which it
contacts the ground, making it grip more in some situations and less in
others. Depending on your riding style this will clearly make a
difference to the wear rate, although it might not be significant.

To be honest though, all this stuff about more traction, or more
protection against slipping backwards by running the tyre the wrong way
is all the sort of stuff that only people who'd be better off just
practicing more care about. I've ridden a brand new gazz with it on
backwards until it wore out, and several the right way round and it
made no difference to the ride.

Can you swap the cranks around?
That's good, cause I was gonna take them off anyway to grease them.
Maybe I should do that. I have splined hub. That seems to solve both my
problems. Are you sure I can do that?

yeah sure, go for it. cause you've got splined you can take them off and
put them back on whenever you want because you won't wear them down
like standard taper.

just make sure you take them off properly, dont whack them with
anything!

instead of taking my tyre off and turning it the right way i just took
the cranks off and switched the wheel around. (i was changing crank
sizes anyway).

what brand of hub do you have?

i think with the koxx splined you need a crank puller.

with the KH i think it's got a self extracting bit but i'm not sure,
neither am i with profiles.

(you might be able to just pull them off with your hands)

if you've got a DX if you undo the pinch bolt on the crank and the bolt
holding it in to the hub, you should be able to pull it off i think.

(don't take my word for any of this, i think that's how it is but i'm
not too sure)
