Tire/wheel issue
I had a flat yesterday evening. Had to bring in my set of 16's (on D-90's) today as the spare didn't inflate properly.
Here's what I found on the rear passenger tire.
When I got these tire/wheel combos this spring from a fellow RL member, they were used but had plenty of tread left. The first thing I did was to have the wheels balanced. This tire required 5oz of weight. You can see the weight locations in the pics.
Is this rim shot? or is there some other issue? Could it have been balanced incorrectly?

I don't see any damage to the rim .
The lead is to balance the tire not the rim .
If you have the tire taken off the rim , then the rim put on the balancer without a tire
you can see if the rim all by itself has run out or balance problems .
If you buy new tires and they put a "**** load" of lead on the rim ,
that's a sign that all is not right with the tire .
If you ask for another tire ...

Then they were pressed heated etc .
The parts would be placed be hand .
Not everyone building a tire had the same skill .
The tire might be the first one of the day or the last one of the day .
The tire might be the very first one built by a brand new hire .

I gave that some thought, but here's why I think it's got to be a balance issue. On the opposite side of the wear (still on the inside of the tire), the little sliver of extruded rubber and some of the little nubby things that were there when the tire was new are still there. It's only on that one section like that edge never hit the road.
I'll bring the thing in and see how out of balance it is with and without the tire. I hope not to be on the market for a single Cup II wheel soon.
