Got Cupping!

The alignment spec's are zero in each case, however only the toe is adjustable. Caster and camber are not adjustable.

All tires are speed rated. Just buy the rating you want, but don't go below the rating of the OEM tire.

I never looked real hard to see if there was any caster or camber to adjust. They must just bolt on no adjustment. So just set the tow and go then HMM :doorag: Bet the shocks gonna mess with the camber some. Depending on what setting you have them on.

Control arms are equal length, so camber won't be affected even with different ride heights.

I think mine has the same issue. I took mine to get a new back tire put on and my dealer said my front tires looked good but was wearing some on the inside. They rotated them for me but now my bike handles terrible! He said I would have some vibration until the tires wore down some in their new position...but I did not realize it would be that bad...it only does it really noticeable at speeds 55-66....then it goes back smooth until i hit 74 +. It was so bad on interstate yesterday the people behind me said they could see me fighting it in the curves going up the mountain to Asheville. It was not a good feeling. Should I keep riding to see if it quits or take it back to see if something else is going on? btw I have 17,700 miles.

First, it depends on what kind of wear you're getting. If it is just wear without cupping then you probably have a toe issue. Just rotating tires will not fix this.

If they did not dismount and re-mount the tires to spin the correct direction you added to your woes (which is what it sounds like happened). If this is the case you need to put the wheels back where they came from. Those are directional tires and you don't want to run them backwards.

In any case you need to fix the problem causing the abnormal tire wear and get the tires to where you're not having so much problem driving them. It may require new tires but that would be a waste if you don't fix the original issue.

If you set the front shocks to a firmer setting will that keep the tire flatter on the road? And will this reduce the inside wear some.

I ask this because I keep the front at 5 and the rear at 4 with 20 psi front and 28 rear and I see no wear on the front inside. I use these settings because even win I breathe helium I still weight 200. /Ken krb1945

Spring setting only affects ride height (load carry capacity) and to some degree, body lean when cornering (plus a stiffer ride all things being equal).

They will not affect tire footprint nor tire wear patterns. Dampening, which is not adjustable, can affect tire wear but this will be a cupping effect not one side or the other wearing more than the rest of the tire.

Toe is adjustable and can cause inside or outside tire wear depending on toe-in or toe-out.

Caster/Camber are not adjustable so though they can affect tire wear there isn't much you can do about this aspect.
