Pictures of my rear tire on front

Please correct me if I am wrong, but isn't this tire mounted backwards?  The unidirectional tread should move the water away from the tire, not towards the middle?

What size tire is that one?

I thought the same thing, but when compared to the Cobra Venom regular tire and the new Cobra it does the same thing. Here's a picture of the Venom R http://www.google.com/imgres?imgurl=http://xlforum.net/photopost/data/500/medium/Avon_Venom_110_90_19.jpg&imgrefurl=http://xlforum.net/vbportal/forums/showthread.php%3Ft%3D84431&usg=__JOGO3n9ZBekrhaFJoxHYT8NJyV8=&h=450&w=600&sz=28&hl=en&start=40&zoom=1&tbnid=_OoXtAfN4U0M3M:&tbnh=127&tbnw=170&prev=/images%3Fq%3Davon%2Bvenom%2Br%2Bmotorcycle%2Btire%26um%3D1%26hl%3Den%26client%3Dfirefox-a%26sa%3DN%26rls%3Dorg.mozilla:en-US:official%26biw%3D1280%26bih%3D560%26tbs%3Disch:10%2C855&um=1&itbs=1&ei=NiLQTNKhLqHfnQfM7P2NBg&iact=hc&vpx=638&vpy=287&dur=936&hovh=167&hovw=223&tx=133&ty=113&oei=CCLQTJ_hJoiHnQeH0NyPBg&esq=3&page=3&ndsp=21&ved=1t:429,r:10,s:40&biw=1280&bih=560

That one is a 130/90/17. Can't hardly tell any different than the stock tire. Speedo reads about the same.

Sorry for the stupid question, and I ask only out of curiosity. Why a back tire on the front? Are there advantages to it?

I'm not sure what this question is asking and I have no idea about "moving the water away from the tire, not towards the middle . . . ." I have read of others who mounted the rear tire on the front to rotate in the same direction as if mounted on the rear in order to have "appropriate water channeling" or some similar concept.

I know nothing about tread design, water channeling or water dispersion, tread laps and joints, or anything else of a scientific nature regarding tires.

The only thing I do know is that if one tends to view the tread pattern of a tire as an "arrow" the tread pattern of the front tire is exactly opposite the tread pattern of the rear tire.  When looking at the rear tire from the rear, the "arrow" points up (the tire runs in the direction of the "arrow").  When looking at the front tire from the front, the "arrow" also points up (the tire runs opposite the direction of the "arrow").  I'm not talking about the directional arrow on the sidewall, I'm talking about the angle of the tire tread.

I do not believe I have ever seen an OEM front tire mounted with the tread pattern in the same directions as the rear tire, or the tread pattern opposite of that show in Warlock's original post.

This photo shows the OEM Dunlops for the Valkyrie, with the red arrows showing the direction of rotation.

The only advantage I am aware of (other than adding a few extra choices) is that the tread depth of the rear tire is often greater than the tread depth of the corresponding front tire.

The front tire pictured in my previous post had 10,400 miles on it.  The tire below has 13,200 miles on it.

David -- Very interesting on the Venom R's.  I still question the mounting; always been told the "V" points down when viewed from the front.

Vanagon40 -- The issue is the liklihood of hydroplanning when mounted wrong.  Bad on a car, really bad when on the front of our cycles.

I do not mount my own tires.  I have three bikes and a sports car, each with unidirectional tires and all are mounted with the "V" down when looked at from the front.

I would like to hear from a tire expert on this, as the correct knowledge could save a life or two.

Anyone?

It should last longer. This is my first one so only time will tell. Also stock front tires usually has 5/32 thread depth and this one 11/32. Stock tire runs around 150 to 200 dollars and this one around 75 delivered. Lot of difference in price, but if I have any issues with this tire I will pull it and go back to the stock tire. I will be posting on how this tire handles and any issues with it. I sometime runs curves pretty hard and will be putting this one to the test.

Not a expert on tires by no means. But if you follow the V pattern down till it hits it would throw the water outwards. If the V is opposite of mine when it contacts the water it would throw the water forward and have more resistance. Just my thoughts on it.

I believe that mounting a rear on the front with rotation backward has more to do with braking than water dispersion.  Someone with more knowledge than me will surely chime in.  I have seen links to websites showing the reasons for doing so.

[Walküre]

The way I understand it, is that the belts are aligned to overlap in the direction of stress. The stress in a standard rear tire, on the rear, is during acceleration. Picture if you will, a roll of toilet paper. Lay it on the ground, and hold it IN PLACE, but try to turn it one way, like it was "accelerating", or spinning rubber. It will either stay rolled up, or try to unroll. A rear tire is made, so that under acceleration, it stays rolled up. Now, if you put that tire on the front, suddenly the stress occurs under decceleration, or braking as we know it. So, to prevent it from trying to unroll, we put the tire backwards, since the stress is backwards to it being on the rear.

Make sense? Clear as mud??

I will be putting mine backwards, when I get it. I've never heard of anyone having an adverse affect putting it on backwards.

Warlock nice looking tread. Hope it works out for you.  Look forward to your milage and handling post.
  The reason to mount backwards as explained to me a while back.

My first one after 30k. Let the air preasure get too low for too long or probably would have went 50k.

Would be great to get 15000 miles out if it. The roads around here eats tires pretty quick. Got the gray rock slag for out roads.

That's the best explanation I've seen to date. Thanks!
