I know someone else had the same problem, but I wanted to post some pics showing the problem area.
first a couple of pics showing the MT 295/45's
Now for the offending sway bar mount.
The sway bar mounts come within a 1/4 inch of the inside lip of the rim and that just so happens to be where the tire shop has to mount the weights for balancing. Glad i checked clearance before running them or it would have ripped all the wheel weights off. They used a lot of weight to balance these, probably partly do to them being 10 inch and also they didn't put any weights on the outside lip, but inside put them right behind the spokes.
This is the passenger side, which required a lot more grinding than the drivers side. I even ground down the bolt tip a little.
I love these tires. They handle better than my M&H drag radials and stick great. I don't even think I'll need a burnout at the track to accomplish my goal which is an 11 second pass without breaking anything.
