Rear tire (tyre) help

[Coolbreezin]

BWG56 - Adjusting my belt via the bolts will not fix the problem. Over the 10 years and say maybe 8 rear tires, at some point the alignment would have been right so this doesnt happen. Ive had Avons and Metzlers, both did this.

Sven - Look at how far to the left the wear is. If a road crowned that much I would feel it in the bars and everyone would be able to see the road like that. Im guessing 30 degrees; roads dont crown that much.

Just for giggles, do any other bikes wear like this? I had a Ninja for 21 years. Rode from VA Bch to Venice, FL and in between, never wore like this. My wifes V-star doesnt do it. All my friends HD's dont do it. Its not the road. Im thinking engine / tranny alignment. Besides Curtis, anyone concur?

Thinking about this, my original Venom did not wear like this, it wore out right in the middle with 8K on it. Maybe this has something to do with the Manufacturing of the tire. Meaning it might have something to do with the belt construction of the tire.

BWG, excellent point. This may also explain the spitting.

How many hours labor would it cost to have my engine / tranny / wheel aligned professionally?

Back on the group ride in PCB in the spring I made it a point to look at the rear tires of bikes I was following. I could definitely tell where the tire was making contact with the road, and most were different. I rode behind Tapio several times and his K9 with the 300 never seemed to be riding in the same place. Sometimes it was centered sometimes it was just a little off, and sometimes it was way off center. It did not seem to be the crown in the road so much, but more if we were going straight or around a slight curve. I was surprised by how far off center some bikes ride on a slight curve. I guess the wider the tire, the more off center they rode.
I think the off center wear pattern may have to do more with riding style. More pointedly, how you corner. I don’t really know why, but I am more comfortable taking a left hand turn than a right hand turn, and so I get back on the gas sooner coming out of a left turn than I do when taking a right. Back when I rode rice burners years ago I don’t think I had this issue.
In my opinion, I don’t think it is an alignment issue. On a two wheeler, the wheels are self centering. Think of it this way, the driven tire (rear) tries to go straight, and the steering tire (front) is turned so that it matches the same direction (while going straight). So if your rear tire was way out of alignment (side to side) with the frame, when you were going straight down the road, your bike would be riding a little sideways or “crabbing”. The vertical angle alignment is not adjustable on Big Dogs.

vertical alinement jmho bad wheel bearing will cause a problem and so will a cracked frame

I did notice that offset of the wheel. I was more looking at two countries matching road pitch and that same offset, even with your tire print's offset. I don't want to buy into it either with that road pitch variable.

One way is to hose the road down, ride thru the wet so it tracks an ever so wet a foot print. This way you can see the back tire ride thru the front wheel's and see if those are centered to each other?
