Unhappy Dunlop Tire wear

Has anyone seen this before? Seems unusual to have the left side of the front tire wear so much more than the center or right side. I was following the service manual and kept the tire inflated to 28psi. I have now been told this should have been closer to 36psi. If 28psi is under inflated would it cause this type of wear? This is the front tire for a Vulcan 900 classic with 5900 miles (original tire).

Would like to hear everyone's thoughts? Is there a way to check alignment?

It is not particularly unusual to see the left side of the tire worn more.

There are two arguments why:

1. Left side of the tire gets more miles put on it. Left turns (at least from the RH side of the road) are longer than right turns, therefore left side accumulates more miles.
2. Crown of the road.

I'm more in tune with #1, but in the end it doesn't really matter. What matters is that what you're seeing isn't inherently indicative of a tire/tire maintenance problem.

Probably because you're right-handed.
Otherwise, could your alignment be off because you tried to track your belt?

I'm just now hitting 6000 on my custom. The wear on mine in more in the middle. Umm! You wouldn't happen to be sitting side-saddle would you?

I think it's way too far down the side to be an alignment issue. To wear that far down the side you'd have to be leaned over...like in a LH turn.

Also, makes me wonder if this bike had a previous owner and it was laid down...

I have Dunlop D404's on my bike. I have more than 5,000 on the tires and they are wearing pretty evenly. Also I run 40lbs in my tires, instead of 36 or 28 as, recommeneded by the tire manufacturer. Tire pressure in the book gives a smooth ride, but 40lbs gives better tire life and gas mileage.

In fact, I have close to 10,000 on my tires and they are about 18 months old.

Thanks for all the replys so far. Getting a new tire put on this afternoon.

Both make excellent sense. I have noticed that are roads here in So Cal. can have a pretty good crown on them, I have even noticed myself leaning that way on some of them.

This is the front tire, would rear wheel aligment impact the front? the rear tire looks really good right now.

I'm the original owner, so no.

I think it could/would, but any time my rear wheel alignment has been off any appreciable amount I've felt it in the bars, needing to compensate more one way or the other/work harder to keep the bike going straight.
