Fallout & odd tire wear

Im sure theres no connection, but I have to ask. I generally understand what fallout is regarding the front wheel. However, as soon as I let go of the bars, the bike leans/turns to the right. I have to lean waaaay to the left to compensate, but it doesnt really make me go straight. Im wondering if there is any connection with the wear on the left of center of my rear tire Ive had since day one and with many back tires (mostly Avon, one Metzler)?

i think the term you mean is fallaway, but whatever, you also have to take into account the crown in the road causing the bike to run to the right. more crown=more left lean. unless of course you ride on the wrong side of the road.

Thank you for the correction. Ive tested this pull to the right in parking lots, wrong side of various roads and speeds. Keep the ideas coming.

From the pictures, it appears your rear wheel is worn on the left side way more than the right side. I would check the alignment of the rear wheel, could be worn rear wheel bearings and under power the belt is pooling the wheel forward causing it to wear on one side (left) more. It wouldn't hurt to check the alignment of the rear wheel or the fallaway.

I am leaning (pun intended) towards two things.
Mis-alignment of the rear tyre/rim.
Or
Bent/twisted frame.

BUT don't discount, rear piviot bushes, the way you ride (do you sit off to one side).
Testing the bike with the tyres worn is of no value. You need to put on two new shoes and ensure yoou belt is at the correct tension and the rear rim/tyre is aligned perfectly.
This means you check it, not the work experience kid at the tyre shop.
My last rear tyre cost me and output bearing and seal and the pulley, because the nob who fitted the rim did not check either of those things.

If you have had this issue from the start, it may be an alignment problem. It may even stem from the motor-trans alignment??

About 4-5 yrs ago Tampa checked the frame and alignment and reported it as being ok. However, Im up to 5,000 miles on this tire, and its just starting to show the ear, so Im really confused but happy. Last couple Avons I only got about 2,000 - 3,000 miles each.
Air pressure is good. If this is a bad bearing, than it was bad from the manufacturer. Plus, as many times as Ive had the rear rim off I would have seen it. Also, this is a recalled rim, replaced about 6-7 years ago. Doubt its the bearings. So no relation between the fallaway and the odd wear?

I'm in with HMAN. The whole bike might need to be re-aligned. My buddies Pitbull was wearing the same way and his was way off. I'm not sure if this is only true on rigids.

you have a good point (checking wheel bearings)most just stick there finger in the hole of the bearing turn a feel.this is not a way to check bad bearing surface or lack of grease.i have no idea how to use caplocks or spell check on this table sorry.

1. If I took my tire patch width, took a ruler, went to the road I ride with this edge or crown, how flat is my tire to the ruler to the small patch of that road. Do we see a crown happening off that width we have an air gap under the ruler on the tarmac?

2. That in motion runs in a straight line. Are you correcting the front end at speed, not in a parking lot? If I run a line down the middle of the bike, saw it in half, wouldn't my left side be heavier? For every action of weight left, I'm compensating in the parking lot with a lot of right steer to keep the left hooked to the right, I want to move the weight to the right, right? (pun intended)

3. If Tampa took a tape measure and said straight, I want a second opinion with a laser beam kind of frame jig looking at the twist of said frame. Either it's bent a 32nd or it's square to the beams.

1. I want to pump the tire up to 60 pounds so it peaks or as much V as I can get out of the footprint, not a U over the wet.

2. I want to hose the street down as long as if I rolled the tire out to its full length. This way I have a full wet tire.

3. I have to figure out how wet I make the street so I see:
a. How much hits the road is my wet line left on the tire, but a thin shadow.
b. How much walk my front wheel moves in line with my rear wheel.
c. How many times I need to wet and roll before I see the better wheel over wheel, I already see where my wet tire line is of the rear and if that is cocked to one side or hits center: now I want to see where the wheel lines up with the back.

Bearings need to be checked or replaced every 10,000 miles. As said, if bearings have any issues your alignment will be off.

I started a thread here a while ago regarding the odd tire wear. This thread wasnt so much about the odd wear but if there was any relation between the fallout and odd wear.
As for reasons Ive been given for the odd tire wear...wallet(s), road crown, if I lean while on bike. None of them apply. The wear strip on my tire would require the bike to lean at 30 degrees as I traveled.
