rotational tyre direction?

[trials hoe]

So I just stuck a new tyre on the back (super tacky high roller) and I'm a bit spoiled for grip as it is, but I'm wondering if there would be a benefit from running it the opposite way round to the stated rotation direction specified on the sidewall with regards to maximizing the level of grip?

The way I look at it, tyres have a designated directional rotation pattern so they can 'cut' through loose or muddy surfaces and shed any material caught in the tread while also minimizing rolling resitance. with trials muddy/sandy ect. surfaces are like the mortal enemy (to me anyway, i avoid them like the plague) and practicality is an area ignored with the whole trails scene, so a specific rotational direction becomes a moot point right?

Using an example the tryall stickys have a tread pattern the other way round to a conventional tyre, with 'normal' tyres like this /\ and the stickys like this \/ as you look down on the tyre from above....if you get what I mean

I've been wondering about this and the advantage (if there was to be one) will only me marginal, but every little advantage is always going to be a good thing anyway, so anybody else had this thought?

that depends on the threads design,but yeah,most tyres get a lot more grip when put on like

-on the front "arrow"pointing forwards"

-on the rear "arrow" pointing backwards"

you´ll have to try,as every tyre reacts different in different positions.

but you cant damage anything,do it.

Well the forces are backwards in trials mostly so what you've done may help? If you do a pedal up for example you're more likely to grip instead of slip down perhaps?

I tried this on my big betty running square edge on rotation seemed to help

yeah if you look at the try-all tyres the arrows point backwards.

The arrows are mainly there for water displacement.
