Forks or shocks possibly going bad

1-everyone here is correct about once a tire starts to wear funny, you have no chance of saving it.

Technically yes and no. Compound wise, pressure wise, I've seen a tire clean up with different pressures. We are talking about high speed closed course, and within say 5 or less laps on a gearing/suspension shakedown; schooled my ass.

2-have you been replacing your wheel bearings each time you replace your tires.

Which made me think... with back wheel off the ground, hands at 6 and 12 o'clock, is there any movement at all? That one bearing drop would cause the one side of the tire to wear. However, with the j-hook under the swing arm sides, that one adjust rod would point that out on the bearing drop as a variable; swing being square to the frame to axle and all that.

Then the northern crowd should go out to their car and look at the wear profile on their tires. Flat across the treads?... scratch my head on this one.

I swear, bdm and Willy live not 30 miles from each other. Willy is hording all that coinage in his left pockets.

Willy, just for grins, pump that tire up to 60 psi and walk that wet line to 'wear' it is ever so dry. Dry line has to be dead center is the plane down the center of the neck-to center of axle. That says, tire's center is the touch point.

Obviously you are going to pull the wheel off. I'd be grabbing the swing and yanking in every direction to feel for slop. If this was the same cocked tire into the belt thread, where the swing pivot shaft is a two-piece-screw-type on your year model as well, I'd inspect the integrity of the two-piece not having the threads torn up and collapse it that way.

I mean if we are talking monsoon rain up the northern part of the country to have that steep a crown, and are we talking where Willy lives has an even steeper crown? Looking at bdm's tire wear, it's hard to swallow a crown.
