They took my original D407 tires off at about 9,100 miles.  The rear was far worse than the front.  I've heard from UFO_HOG (Bryan) and others the 408F works well. 

But what about the rear?

[sem_bunda]

I've got the 408F and 407R, almost 12k miles and no cupping, barely noticeable whining noise from rear that disappears if I have BSR or t-bag on.  I would think by now the cupping would have begun.  Can't be road conditions because I've been on all kinds of roads in several states.  What gives for so many SERG to have cupping and others not?  Doesn't make sense to me.

I noticed on one of the replies earlier someone mentioned getting 30k on a tire?

[GregKhougaz]

I think the "whining" is indicative of cupping.  But if it's only barely noticable after 12K miles... that's very good!

The second set of tires now ( front 408 , rear 407 ) was better than the first , they both will be replaced today because cupping started again with about 8k miles on them , i hear them whining .
 When I look at the front-tire then i can see that the right side is more cupped than the left one , that is because of driving right side of street than you have right-turns that are closer than all left-turns on the street , so you have to brake more for right turns and you have to lean more into them .
The rest of the tire would still be good for another 5k miles riding straight on .
But it is getting winter and a new set of tires should be not the cause of slippering .
Also the rear tire would be goog enough for another 5k miles in the summer (but not in the winter) for me .
The tires on my Fatboy had to be replaced at maximum 4k miles , so 8k on the SERG is double , i don`t want to complain.
And it is surely a question of riding style , aggressive or not , how much miles the tires will be good enough .

I managed to get 14,300 out of my first set. I was happy with that.

That shows that you are able to handle your bike carefully enough to save your tires , i wish i could also .

Dealer just replace my rear D407 it was cupped 3/32. The bike had 10700 miles. Sure is nice to ride a quite bike again, hard to beleive the cupped tire made that much noise.

Brad,  Great jog.        If you don't mind, please tell us what you had to do to get the replacement.  It may help some of the folks here.  Thanks!

I just asked and 2 hours later I had a new tire installed including labor (same with the front tire 2 months ago new D408). My dealer understands the D407 are junk!! The shop foreman had just returned from the Mother Ship in Milwaukee and they had allot of discussions on the D407 issues he claimed.

I took Petunia in yesterday for her final service of the year before she goes into storage for the winter.    The service manager called me today and informed me that the front D407 tire is starting to cup.  Then he ask me if they could replace my D407 front tire with a D408 at no cost.      I guess it was starting to show at 4400 miles.

The dealer took a big jump in warm and fuzzies today.

good service from the dealer , wish all would be like him .
