removing tire marks from concrete?

give it time to remove marks from concreate. My teacher let me mount my
6' unicycle in class, I almost got on but ended up falling off and
leaving huge black mark on the wall. Any ideas for getting black marks
off of painted walls?😄 😄

For removing tire marks on painted walls: Try an eraser.

For smooth surfaces a pan scourer might work, for concrete a stiff
brush might do it.

I left tyre marks on the walls of my living room while learning to ride.
I just moved the sofa slightly so my housemates wouldn't notice... 🙂

You know, when I was a kid I remember leaving long skid marks with my
Stingray. All it would take to remove them was getting down on my hands
and knees and blowing on them.....the powdered rubber just dispersed and
the mark disappeared. I think that the marks from uni-ing are ground in
there a little more deeply.....I haven't tried blowing on those. We use
damp paper towels on the gym floor at our meetings, but that's a whole
different surface. I'd try one of those erasers that woodworkers use to
freshen up a sanding disc.....that ought to work.

I used to have contests with my friends to see who could leave the
longest skidmark when braking on a bike. it was pretty fun....
but yeah, they'll eventually go away by themselves, sort of like chalk
drawings, they just disappear.

Thanks all 🙂
I know they will disappear in time, but I didn't want the court
"management" to get upset and say something. I tried sweeping with a
very stiff-bristled broom, but that didn't work too well.

Same here! I did them on my lil BMX b*ke when I was little. Good thing
I've got a red tire on my uni or else there'd probably be more!

i think i would take a stiff nylon briste brush and some water and just
scrub. Apply water liberally during scrubbing to help float the
particles away.

I'm assuming most of the marks were made while going forward right? So
to erase them, it's simple!: just ride backwards on the forward marks!

Pressure washer. They're getting pretty cheap. The marks will return
and look even blacker against a nice clean driveway though. Can't win.

Great 🙂
I will keep that one in mind. Maybe if I would have taken some video of
learning, then I could just play the video backwards? 🙂

Trapper, good idea, I mean this funny: pressure wash the marks off the
sidewalk and they blow right onto my neighbors trailer!
That would cause some interesting discussion, no? 😉

The marks are caused by friction between the tyre and the concrete,
which abrades a small amount of rubber from the tyre with each sharp
turn, and ingrains it in the porous surface of the concrete. This is
made worse if there is considerable weight applied to the unicycle - for
example by a rider who is built for comfort, rather than speed.

Kill two birds with one stone: smear the tread of the tyre with butter.
This will reduce the friction, and therefore the abrasion. Also, you
will have no butter to eat, and will have to make do with a low fat
spread on your sandwiches, so you will eventually apply less weight to
the unicycle.

An invoice for my consultancy fee is in the post.😎
