Why does the FSM say to put the weights on the right side of the front wheel? The shop put them on the left side and I did't notice -will it really make a difference? My 09's rear wheel bearings were very notchy after only 7K miles so I replaced with the 10 wheel and mounted Scorpion Trails.

Perhaps the thinking is that's where the brake disk is making the center of mass offset?

Just guessing.
Personally, I didn't put any thought to my balance weights when mounting my tires.
I just put weights on the rim.
Seemed to work.

Perhaps it would work better if I had put them only on the brake side?

Doh! I have missed that nugget of info for 30k miles.
Always split the weight and put them on both sides.

I also missed that info for the first ~40k miles on my Uly. The last front tire I mounted I made sure to locate the weights as directed. I can't really tell any difference.

My guess is that it's more likely that if "compensation" is necessary it would be required on the brake rotor side, since the rotor might not be perfectly machined and/or centered. If you put the balance weights on the other side of the wheel to compensate for an imbalance in the rotor, the net force would be slightly "eccentric" to the wheel centerline which would tend to make the wheel wobble.

You've got to figure they had a reason for specifying it the way they did.
