Tire wear seems to be more on the left, brand new Pilot. Just a bit worried as to why.

More left turns then right turns?

If it was a wheel alignment issue the wear would be in the center as opposed to the side.
Usually the 'crown' of the road will bias the wear a bit to the left.
Also, most riders are more comfortable in left turns, and tend to push a bit harder.
it's funny, I feel more confident in left turns than rights, but I'm right handed thus right minded. Weird

I'm left handed, and feel more comfortable in right turns. [beer]

medical explanation?
Dunno.
Seems to be a body position/bar pressure/footpeg pressure thing that comes with either handedness.
Try to 'record' how your body position is in a left turn, and replicate it in a right turn.
It's not easy to do, but it may help.

Not more, but longer because we ride on the right side. Don't know if it will affect wear enough to notice.

left brain/right brain thing.
i think its also associated with whether a person is left or right eye dominant (which goes back to left/right brain stuff)
its also a question of where the controls are. you have to manipulate the throttle with the right hand, meanwhile on a right hander you also have to counter steer with the inside hand. if your controls arent set up exactly for you, this makes it harder to do right handers.
in america, your more likely to do a right hander than a left hander too.

The "crown" of the road has no effect on your tire's wear pattern. Most roads are engineered with an inch of fall from center line to shoulder to facilitate drainage. Any more than that and the triangulated shape of the road would create an unsafe point/spine at the center line for vehicles changing lanes/passing. To keep things short and sweet. Standard US lane width is 11ft. For the every inch across there is an elevation change of roughly .01 inches or .25mm. Lets say the contact patch of your weighted rear tire is 2in. That means, on average, your tire is experiencing a .02in/.5mm elevation change across the width of the contact patch. Have a buddy sit on your bike and lean the bike left from dead center. Tell me what angle is consistent with your wear pattern. [coffee] Ask yourself if you ride down the road at that angle. You will see the .5mm of "crown" you and your tire are overcoming is not and cannot cause the wear that you see.
The difference you are seeing is because we drive on the right hand side of the road in this country. Meaning your visibility through left hand corners is much greater allowing you to push harder and take them faster, scrubbing off more rubber on the left side of your tires. If we drove on the left hand side of the road you would see the same accelerated wear on the right side of tires.
Go out and find some nice right handers to even it out on 8)
It's an illusion. You're showing us a dirty tire (more dirt on left side because your last turn was a left-hander on a lightly-traveled residential street)â€"wash it off and look again. ;)

I live in South Carolina (right side of the road) and my wear pattern is the opposite. Me, my wife, and at least two of our ridding buddies wear the front tire to the right of center faster than the other sections of the tire. My only guess is that we are loading the right side of the tire on right-handers more because of the tighter radii of the curves. You'd think being leaned over longer on lefts would make up for the difference. [laugh] And this isn't a single tire occurance. We've worn out every front tire faster on the right side than the left side for at least 30 tires between us.
Drive around the island clockwise more often - works for me.

You're on to the truth with the second bit, but the first part is a myth. There was a web site where they actually investigated this and found that the angle of a road's crown wasn't anywhere near the angle of the left side wear. Not to mention, I ride both directions on the same HOV lanes, meaning that if it's the crown, I should have equal wear on both sides, but I don't.
The most likely culprit, which matches the steeper angle of the typical left side wear? Left turns at lights. The left turn taken at a light is significantly longer and is taken significantly faster than right turns typically are.
