lol, I bet there was beer involved in the wobble in the first place. Glad to hear you figured it out Doc and good advice for the rest of us.

Bought and mounted a tire this afternoon. Scrubbed it out and took it for a ride on the highway.

Everything is as it should be.

Kinda hard to have beer googles when you're drinking from a can.

Doc

Glad to hear you found your wobble . I changed out my front tire a couple of weeks ago and used the Dyna beads.
First impression was not good. The bike felt like I was riding on a knife blade. No wobbles but not stable. I now have 5-600 miles on the tire and it has improved. I read a article on front tire wear and it made really good sense. Simple physics. I can't remember who wrote the article but it was very clear.
If we firgure we make equal left and right turns, the physics tells us that we travel more on the left side of the tire than the right side. Likewise, if it is city, stop and go, type riding, there are higher stresses on the tread as we turn. The greater travel distance on the left side of the tire will result in faster wear than on the right. Thus you get cupping.
The guys on the Darkside are running a rear tire on the front with the rotation reversed. I took a brand new rear tire and looked at it rolling in reverse and discovered that the contact area stayed on the "beefy" part of the tread (Dunlop 404).
For now, my current rear tire has sufficient life left that I will not be installing the Dunlop 404 on the rear. I'm pretty sure I will go to the Darkside and then put the Dunlop 404(rear tire) on the front with the rotations reversed.
BTW, I think it was a RSC member that wrote the article on tire wear.

sorry, I tried to search, but it's such a stupid question that's why I'm sure it's not on here...

What size is our R* Front tire? 130/90/16?

I'm at work and want to order one on line during lunch....

Thanks, Mike

That is correct 130/90-16

Am i missing something?

That's because we hold all the beer in our free hand(left hand) which causes us to lean that way.

Around here the highways are crowned in the middle to shed the rain water off to the sides. My tires always wear faster on the left because the road usually slopes off to the right. I don't think it has much to do with the number of left vs. right turns.

Maybe we should swap tyres with you guys and then get full life out of them As most would know, we drive on the left side of the road so our tyres wear out more on the right hand side due to the cross-fall from centre-line of road (as someone previously mentioned to allow water run-off).

I just dropped my Rocket III off to have a new rear tyre fitted this morning. At 7,000 klms it was badly worn and showed signs of cupping and cracking, mainly on the right side. Mettzler are coming to the party with a discount tyre and are paying for fitting, etc. as I wasn't impressed with the low klms (mileage).

An interesting aspect of our discussion was they are recommending higher tyre pressures than the OEM bike manufacturer. Around here quite a number of people I've talked to with larger cruisers (HDs, Triumph, etc) are saying the same, i.e. run at higher pressures. For example: Triumph recommend 40psi on rear tyre - Mettzler rep is recommending I run new tyre at 44-45psi.

In summary, we're experiencing the same problem, just opposite side of tyre due to cross-fall. Cupping, etc. As Doc mentioned, don't just look at tread wear - also look closely at the profile of the tyre and check for cupping.

I'll be trying to run at higher pressures for awhile and monitor my tyres on both the Roadie and Triumph and see if it makes a difference.

I'm interested in what you guys think on this.
