Bluff Park, Alabama - God's Country! 2011 PW VV | All of a sudden the rear tire has gone away! Left side way worse. How much is left? Just under 10k on the odometer.

Perry Hall, MD | Looks like you've been running on the NASCAR ovals.
Past time to change that puppy.
Hope that someone here can give some good advice on what may have caused that wear pattern. |

Northeast Ohio | Is this an alignment issue or riding the right side of the road crown too much? |

Northern NJ | My tires seem to wear more on the left than the right.
JMHO, I would have changed that tire 500-1,000 miles earlier. After 9,000 the Dunlops seem to lose wet-riding traction. |

Northeast Ohio | I just found my answer.
Taken from: http://www.rattlebars.com/tirewear/index.html
In the case of right side driving countries like the USA, one does indeed ride farther on the left side of the tire than on the right side of the tire. At a simple single lane intersection that is common in most residential neighborhoods, negotiating a left turn will have you traveling TWICE the distance that you do making a right hand turn. That's at a simple single lane intersection. A double lane will have you making four times the distance. But even when you are confronted with nothing more than a left curving road, the radius of that left turner will be larger than if you were coming the other way on the same road making a right around that same curve. If you don't believe this, check out the How Stuff Works web site about your car's DIFFERENTIAL and why it's called a differential (your shaft driven two wheeled motorcycle does not have a differential, it has instead a "final drive" which drives only one wheel). Also note that Olympic runners start in different locations because the outside runners must run farther to the finish line.

Akron Ohio area | I replaced my rear tires at 14,600 miles only because I was going on a 7-10 thousand mile trip and didn't want to deal with a tire change in the middle of it.
Unless you do burnouts or run with under-inflated tires, I don't know what to tell you.
When I replaced my tires, the rear hadn't reached the wear bars and the front could have easily gone several thousand more miles. |

, AR United States | That tire is done. I rode mine over 12,000 miles and had cord showing and air leaking before I finally got down to inspect it. I won't wait that long next time.
Scorebo, if I wait until I am well into the intersection to start my turn, couldn't I take it at the same radius as the right turn? I would like to hear from riders who live in left lane countries if there rear tires wear more on the right. |

New Bohemia, VA | my guess:
1. lower air pressure, below 40psi,
2. rough roads, concrete
3. one saddle bag loaded
4. heavy load
To me, that is your answer, starting with extended riding with low air. |

seattle, wa | The left side wears sooner than the right due to the crown of the roads.
Seriously. |

Bluff Park, Alabama - God's Country! 2011 PW VV | varyder - 2011-10-27 8:32 PM my guess: 1. lower air pressure, below 40psi---Kept at 41 front and rear 2. rough roads, concrete--- Yes, not the best roads around here
3. one saddle bag loaded--- if anything the right sb has more stuff/weight
4. heavy load --- I am ~300lbs - keep the shock at around 45-50
To me, that is your answer, starting with extended riding with low air.--- Normally I would agree....... TNX

New Bohemia, VA | seriously, roads will do that, if there is a lot of flat land and you don't do a lot of twisty, I'll say try a car tire if you dare. I wouldn't want to change my tire every 9,000miles, 14,000 is short enough. |

New Mexico | Well, I am 13+k into the darkside, and about 2/3 tread left. Thinking I will get 30k out of it. First several thousand miles tested my sphincter, but after that I felt just as comfortable and just as safe as the E3s. By myself, two up, highway, city, twisties, mpg, braking, trunk/no trunk - All Good. Not the same as E3s, but still good.
Front tire, changed at same time, probably has another 1k left.

seattle, wa | Ok, how bout this?
The left track of the lane is the one we most ride in, or should ride in. There will be tire ruts in most roads, unless it is fairly new. When we ride in the rut we tend to be on the left side of it, kind of like a reverse crown.
I wasn't about to read all that stuff in the link posted.
Someone give me a condensed version.
Also, is the tire in question mounted on a bike that is ridden predominantly in the left lane of an interstate?

Actually that is your fifth thought.

I have heard of the left side wearing faster than the right, but have never had it happen to me personaly. I got 18k out of my Dunlops on my Vision and was down into the wear bars but it was an even wear.
I can see this leading into a tar snake discussion. |

New Bohemia, VA | Why, tar snakes? I read the article and understand what he is saying for the most part. Mine always wears more on the left, and have never given much thought that it was the crown. However, I find myself pushing the bike to the left side because I'll sit some to the right. That might not make sense to some, but when I went out west I didn't do it as much and my tire wore more evenly. Also, I wasn't doing a lot of left turn leans either as I normally do at home. As I think of the article and my riding habits, the contribution to wear is the harder left turns on a daily bases that I encounter. Take the texture of the road, the weight the tire is bearing and your air pressure and it is obvious to me that the tire will naw away quickly.
But, I'll will say that under 10,000 is not acceptable and though we can swear by it that is not the case, air pressure is mostly like the biggest contributing factor. We must always check our our pressure cold, the colder the better.
Now you all may start your tar snake discussion, for what it is worth...

| its a little of both guys. crown, longer radius, I have about 10000 miles in Europe on a bike and guess what????...yup the right side of the tire wears out over there. crown plays a part, but it seems that taking longer, and also faster, left turns in the US makes the left side go. opposite of europe |

| Replaced both of mine at 10k. Picked a couple roofing nails in the rear sidewall so I decided to replace them both. I had about 4-5k left on them. |
