Rear tire rubs.

[89-300ce]

The tire is a stock size Elite 2 on the back with 42psi in it. Two up with maybe another 20 lbs of gear.

First chance at some real twisties but two up and keeping a safety margin, not dragging pegs. I didn't feel anything odd other than a slight wallow/hinge in the middle feeling at _my_ limit which I assumed was the softly sprung damped suspension. The rubbing appears to be from the brake stay on the side wall. I can't feel any play in the wheel or swingarm when I try to twist it. Is this normal or an indication of worn bearings somewhere? Anything I can check/test?

ps. In three years of normal riding/commuting there have never been any issues.

That to me sounds like something is heading south.. if it had been right after some recent install or other maintenance, I would say that was your problem but three years of normal.and now you have a problem leads me to believe that something is worn and out or place.

Agreed.

Double check the left side axle spacers are put on the correct way.

Some tires do "grow" over time. Although it usually happens in much less than 3 years. How long have you been running 42 psi? When was the tire replaced last?

I just raised it to 42psi for our annual road trip, heavy load plus trailer. I've done nothing to the driveline/tire in the last 3 years. Tires are old , on the bike when we bought it. They where like new when I got it as the bike had seen limited use from the previous owner. They are probably 10yrs old now Is it possible they could grow that much from heat. The tire was quite hot to the touch when I took that picture.

If there was play in the swingarm bearings or wheel bearings could I feel it by just yanking on the wheel?

Most likely it was the added pressure that got the tire to rub and the rubbing created the heat which increased pressure to increase rubbing.

yes that should show any play. :good:
I've read where some have bent the brake stay to stop tire rub. I haven't done it myself so I've no idea how or how far.

If you drop the pressure, does it still rub?

Play in the swing arm bearings would not cause the tire to rub, since the axle for the wheel is mounted to the swing arm...if the arm moves, the wheel moves too. At least, I mean it wouldn't rub on anything on the swingarm. It might rub against the fender, or bag/shock mounts, but not the swing arm. That's my story, and I'm stickin wid it.... :yes:

Like Slab, I believe I have read of others who have moved the brake stay for clearance.

That makes sense.

Probably not. It doesn't rub at any pressure on the roads around my home. It was my fist chance to push the bike through some twisty bits, Hwy#1, Mn. through the Superior Forest and I thought that maybe the extra force from the turns was showing up some play/wear in the rear end that's not normally apparent. I'm going to prod and pry at the rear wheel a bit more and if I don't see any play I'm going to call it normal.

I had the problem with the tire rubbing on the brake stay myself. I removed the stay and put it on flat surface and made an flat spot on the stay where it was in contact with the tire. Then I took a straight edge and made sure the stay was as straight as I could get it ,remounted it and have not had any problems since. I painted the stay before I put it on.

Thank you.
I will do the same.

If it is in fact a E2 and not a 404 then it should not be rubbing under any circumstance and need no modifications.
It leaves me to believe something is going wrong.

Do not take chances with your life,you may just have dodged a bullit of a blow out.If that tire is 10 years old (and appears ruined now anyway) replace it with a good quality touring tire and look everything over close as you do the job.

Please do not gamble with your life on that tire anymore.

My SEi rubbed when I bought it. The old tire had expanded. New tires, problem solved.
