Need help with tyre rotation direction

[2DIE]

I bought some Vredestein Spotted Cat tyres from CRC but I can't work out the tyre rotation direction.

I've look at Google images and people have them installed both ways, there isn't anything on the tyre with a direction either.

Should the rotation be to the left with the wide part of the block making contact first..

Or should the rotation be to the right with the narrow part of the block making contact first?

My guess would be narrow part of the block making contact first. I did have one tyre that had reverse direction if it was on the front or the rear.

Left for my money. Actually, my money is on right now I think about it.

Here are some shots courtesy of the interwebs. Looks like front points forward and rear points backwards when viewed from the top down.

I'd say that the sidewall in the photo is drive side, that way the big edges are on the braking edge and the small ones are rolling. I know the ramped edges face the front on Minions.

The blocks look like little fighter planes.... Pointy end in the direction of rotation.

Do you want them to brake or accelerate? The wide side will push/stop you best.

These rears point forward

I think you would want them to point backwards for acceleration grip on loose surfaces?

I have the front on pointing forward, I haven't put the rear on yet.

I'll put it on today (not sure which way) and write to the manafacture to confirm although like most big companies I don't expect a reply.

I won't have a front brake so I'm not sure what's best for the back in that case. Probably for braking but I assume that will wear them a lot quicker as well.

*edit*
I guess with 1 brake I should have the rear pointing forward for the extra stopping power.

Oh no, well, I'm fresh out of ideas now. toss and coin maybe ?

That makes sense.

It may not make a as big a difference. I have some Larsen's on backwards which seems to work well once they have worn a bit.

I do like rotation markers though

Go left.

I was thinking space invaders or an 8 bit dick and balls graphic.

The tyres look like they will roll pretty well on hard pack.

Damn, does remind me of the ship in Atari's Asteroids.

+1, a bit minimal Hutchy Python-esque too, if that makes sense to anyone

Rotation markers place unfair restraint on the tyre. They should be free to roll whichever way they feel.

You are man of no rules living big, wild and free. No rotation markers will contain him :heh:
I bet you even leave the toilet seat up.

He has a son to blame it on......so, of course.

You assume he lifts it up in the first place...

When you are called Boom King then anything is possible. I bet he has minders for those trivial tasks.
