I made the 2nd and 3rd belt for MRT tires, you know the ones that go on School Buses and big rigs? I also spent a lot of time on the RTS tire machines. I do know what I am talking about regarding the construction of tires.
As my comment about front/rear tires being illogical, what is illogical about it? The HD Dunlop tires says on the side of it that it is a FRONT tire. I put it on the back of my bike. Again, what is illogical about it? It was a 16" tire, and it rides fine.
That was a good job, I hated to lose it. But got in a little trouble, the Feds didn't like my 2nd income, lmao.
I worked at a GoodYear tire plant for almost 8 years. Goodyears, Kellys, Dunlops, and one other generic brand were the SAME EXACT TIRE! The machines made the same raw tire, some went to GY molds, some to K, Some to Dunops. Same tire, just different branding on the sidewalls.
As far as front versus rear, today I put a "front" tire on the rear of my Sportster. Are there any safety issues with that? It is a Dunlop HD tire. Thank you.[/quote]
Your comment at the the end if illogical. Not sure what you are trying to say.
BTW - were you a janitor or tire designer at Goodyear? That might make difference on the credibility of your statement too!!!

I've ridden 100K's of miles with D402's and although the groove-tracking behavior is irritating I've never found it to be dangerous in any way. BTW Dunlop Elite 3's, which I'm running now, also reduce the wandering considerably. Also, I don't think Avon or Metzeler make a tire in the '09 sizes yet, do they? I know there is no Elite 3 yet.

While toe 402s wander can be unerving, I'd hardly call them 'dangerous' As far as the 407 and 408s, I have ridden them thousands of miles and had absolutely no problems with wandering like the 402s.

Look at the way a tire rotates, the tire on the red bike would have the point in the V hit the ground first, thus channeling the water up the groove and out the side of the tire...
The tire on the blue bike, the ends of the V hit the ground first and channel water up to the point in the V, this will give the water no where to go....
The reverse V seems much better....

you're mentioning something interesting as far as how the tread pattern will affect the hydroplaning effect. water doen't know what direction to go. so if the grooves were at a ninety degree from center, like pointing straight out to the sidewall, it'd work the same. just wait till they wear out and hopefully soon the elite 3 will be out for the 09 models. fantastic tire.

A buddy of mine found Harley Davidson's explanation to the tire issue. The new tire (D408F) has replaced the D407F. They say it will offer increased tire wear. Here's where he found it:

I don't know what to think of wet weather riding and how it will expel the water. When you look at the tire from the front, the grooves look backward, but the grooves are actually pointing back and out on the actual contact patch on the ground, so it makes sense to me that water may be pushed out more efficiently. Who knows, it may actually be an improvement.
