Got the same. Very cool!  Thanks Huge. |

Motorbike, waaaayyyyyy too many highway miles there. I can't believe that you're showing thread without the wear bars showing. WOW! |

Yeah, I hate that I have to ride about 40 miles on straight roads just to get to any decent curvy roads. The edges of my tires show hardly any wear so the wear bars are worthless for me. I honestly thought I had another 1,000 miles to go on that tire. Look at the tread indentations on either side immediately next to the area where the cords are showing. |

I finally ordered my replacement front PR3 this week. Ron Ayers had the best tire price, but they wanted $12 for shipping. Amazon.com had the tire for $2 higher, but with free shipping. I ordered it Tuesday night and it showed up today.
I haven't found anyplace that is consistently the lowest price on any brand of tire. It's always worth the trouble to do a little internet shopping before you buy. |

I am not saying that it is but this looks very much like an over inflated tire. Add lots of weight and hot roads and it will wear out in no time.
As far as "special" rated tires you only need to use those rated by the bikes maker for its max "all up weight" as stated in the hand book.
A lot of highway miles does "kill off" the profile of rubber which is why it is a problem on any good handling bike. Most of the time this is only half the life of the rubber. The Uly however, and I do not know why, is able to run its rubber to near the end of its life and still run good. It is one of the things that I love about this bike. |

Uly Man, I agree that it does look like my tire was run over inflated. I have been running 36 PSI in the rear, 34 PSI in the front. I am heavy, at 230 lbs but generally run alone with empty bags and probably 10 lbs of tools etc in the trunk.
I do have a theory however as to how my tire wore out so quickly. When I was still running the stock warped rotor, it shook so much that I was inadvertently using the rear brake way more than I really like to, just to avoid the shudder during stops. A lot of that rubber may have been scrubbed off while braking, even though the rear brake is weak, at best.
Also, these XB engines have a lot of compression braking, in my opinion. When I slow to stop, I downshift as I am slowing as opposed to just pulling the clutch and freewheeling to a stop. I will probably never change that as I have always done it that way.
Speaking of warped rotors, one of the front rotors warped on the last Gold Wing I bought new in 1986. I must be doing something wrong. I never replaced that rotor but IIRC, the new rotor would have been $300 from Honda, way back then!  |

"Angel ST". This tire, unlike the PR2, is not a duel compound tire. In other words the same all over and not harder in the middle, for good highway miles, and soft on the edges for more/better grip in turns/bends.
As far as a rotor goes? If the Buell one goes it is MUCH less to replace than a pair as you should do on a twin disc system. And of course the need for two sets of pads as well.
"I have always done it that way." And is the right way to do it.
I would advise on the PR2/PR3s. |

Uly_man- I have read that the Pirelli Angels are single compound, but they use a tempering process that makes the center of the tread harder than the shoulders. Perhaps it doesn't work as well as dual-compund rubber, but it's a different means of trying to achieve the same end result. |

Uly_man, I now have the new EBR rotor and mounting kit and EBC HH Pads on front and new EBC HH Pads on the rear. I also just mounted a new Angel GT on the rear. My front brake is working great so we'll see how this all works out this time.
My Gold Wing had a balanced braking system, one front brake is controlled by the foot pedal, along with the rear brake. The other front brake is controlled only by the front brake lever on the handlebar. I had a lot of pulsing on the rotor that is controlled only by the hand lever. I sold it that way and never heard anything back from the new owner, even after I told him it was something he might consider fixing. Thanks. |

"they use a tempering process that makes the center of the tread harder than the shoulders." Interesting and NOT stated on there site or any place I have ever seen.
Buell said there belts would last a life time? Wheel bearings are ok for 50k. I have the only bottle of JD that never empties? Also those those big sexy women will not leave me alone. |

That looks just like a Dunlop D205 that did that to me on my M2. It just looks worn out to me... if you don't have the location or temperament to wear the edges, that's how they die.
If the middle wasn't shot, you could literally get the sides just as worn as the middle in 1 or 2 days of hard riding in the mountains. |

Maybe I could sell the old tire to my brother to run on his 1125R on track days? 
I went for a 200 mile ride yesterday and I was very conscientious of the ratio of straight roads compared to curves. I am guessing 75% of my ride was on straight. I suppose I could haul my bike to the curvy roads, ride back and forth on them and haul it home again but what fun is that? Maybe I'll just move to Colorado....
There is one nice road in SE MN. Houston, Mn to Caledonia. Doesn't get much curvier than that but it is at least an hour from home. Seems like every time I get on that road, I end up getting behind a soccer mom's minivan full of kids. |

My just-changed front PR3 had an unusual (not really weird, just atypical) wear pattern: the center of the tread was probably good for at least another 1000 miles, and the shoulders would have been good for at least another 4 or 5 weekends in the twisties. OTOH the region between the center tread and the shoulders (say 1 inch away from the centerline, and about 1 inch wide on either side) was well into the wearbars, and the water-channeling "sipes" were almost completely gone. My guess is most of that wear resulted from slight lean angles during interstate commuting on concrete pavement. I would have pushed it farther but I figured that's one place it's probably very important to have good tread for street riding, especially given all the rain we've been having lately. |

I have seen the same plenty of times, though not nearly that far off center. Your freeways must have quite a crown. |

The PR2 and PR3's strike a pretty good balance of a harder center and softer edges. I like how they are wearing on my Uly. Better than the Pirelli Scorpion Syncs.
No shortage of peg scraping cornering, but a good long life for mostly straight commuting. |

Was this a front tire? That sort of wear is not all that unusual. Braking forces flatten the central area of the front tire and the wear at the edge of the braking contact patch may create deeper wear. |

I've gotten pretty good life out of the Roadsmarts, over 8K.
Fairly even wear with 90% freeway commute to work and back. Time for new tires though. |

Yea, it was a front. The wear was just different from the Pirelli Scorpion Syncs I'd always run up to this set. Center of tire is not really flattened; it's just off-center where most of the wear occurred. Here's a couple of mediocre cell cam pics. You can see how the profile of the tire is worn in the first pic. The 2nd pic shows how the sipes are almost gone on between the shoulders and the center:
