Proline bowties and AKA ibeams are directional aswell, and neither of them are advertised as a directional tire
if you look at the center pins they have / \ grooves. They should face forward on top like an arrow head

Nothing directional about a PL Bowtie...

http://www.prolineracing.com/images/...ts/9025-0x.jpg

Block angles/split will be the same either direction they face when mounted...

Not seeing it with the AKA I Beams either..

http://raceaka.com/products.php?product=14101

Either tire has the ability to rotate either direction; center blocks look symmetrical to me in both cases.

Care to clarify what it is you see about each that is directional? Colored arrows pointing to the indicated areas along with pie charts and bar graphs will be appreciated.

Do these help.
the pin may be the same length but if they are run in different directions the grip levels will differ because of the way they support each other
remember the tire doesnt always have full contact with the ground so at different angles the grip levels will change.
so you are best to be running them in the same direction.

this is all another reason why i will never buy premounted tires
afew of the guys i race with have noticed that the center pins on the ibeams and bowties wear out quicker on one side than the other, and its usually because the premounts didnt come glued in the right direction

The only difference in the lugs on a bowtie are the cuts go like this / one way and like this \ the other way, what difference would that make in forward traction? you are still pulling on a flat bar either way and the small gap /or\ wouldn't make a difference in traction.
Below is the same tire just turned around:

it was explained to me like this. the surface of the tire isnt flat so the whole pin isnt always making contact. with the short side center it has more support behind the face of the pin.

so if you run the tire in different directions the grip pattern changes

it makes sence to me. i dont expect everyone will agree.

I love the caliber tires on my truggy. They are the best tire I have used so far except in mud they don't work too well. But I find that they wear out quickly. I have been using the m2 compound and usually get 2 race days on a set before they start to lose traction (3-5min quail and a 30min main). A buddy of mine told me to turn them around and run them backwards. The traction is not as good as when they are new but it's better than running them the right way after they lose traction. Not sure why it works but as long as it works I don't question it too much.

Oops and then I read the thread title completly. Revolvers are not directional I don't think it really matters. The only directional tire I know of that the mfg says it's directional is the caliber tread.
