Thanks guys

To answer questions, the tire pressure was as advised on the Metzler website for my particular bike and fitment. Pressure was checked weekly and maintained. When the tire was installed, it was balanced and actually needed very littel weight to be perfect. The shop checked and packed the bearings. I do 70/30 road and town riding. The bike is maintained very well. I have checked and rechecked the alignment per the shop manual and it is perfect.

The Metz ride and handle very well except this last two sets have cupped rather badly. I do know the have a recall for rear tires right now. Wonder if they should recall the fronts as well.

I am going to have new bearings put in and changing the front fork oil. I also am going to replace the steering neck bearings and will make sure the balance is perfect. If this don't fix it, I have told the Ol it's time for a new bike anyway.

Thnaks again for your help

Why not try a different brand tire before you do all that work?

I'm not all that crazy about Dunlops but my front tire (Dunlop) just turned 27,000 and still going strong. No balance / traction problems.

Well my Wide Glide has a 17 stock. I would like to find a 180/60/17 to fit it. But the only one is the Dunlop from Harley. I don't want another Dunlop, I have the stock one almost worn out at 7,000. Would like to try Metzler's this go round, herd a lot of good things about them. It looks like I'll have to run they're 170/60/17. But that tire will have a 10mm shorter sidewall than stock, that will throw the speedo off.

Cupping on tires is almost always a balance issue.

agreed...The problem with regular types of balancing tires, is that the balance needs change as the tire wears. Give these dynabead balancers a try. They balance the tire continually and are supposed to eliminate cupping.

You simply won't believe the ride...
  • Glass smooth ride, every time, all the time.
  • Dramatically longer tire life
  • No rebalancing
  • No spoke or rim weights
  • Eliminates tire cupping.
  • Easy to install
  • Your motorcycle dealer won't want to do it the old way once he's tried Dyna Beads!

I read a lot of positive reviews of them before trying them. I've only got a couple thousand miles on my new Michelin Commanders with the beads, but I can report that so far the ride has been perfectly smooth and tire wear isn't even noticeable.

Ok a follow up. I received a very expensive digital air gauge as a present and decided to see how it compared with my trusted pencil style air gauge.

Air gauge for front 40 psi Digital gauge 51 psi
Air gauge for rear 43 psi Digital for rear 55 psi

Don't know if that might have caused the cupping but believe me, I will be using the expensive digital gauge from now on.

Correct me if I am wrong but the way I understand tire size is the first number is the section width in MM ie 180 would be 180 MM wide not high. the second number is a ratio of width vs height thus the difference in changing from a 180 to a 170 would be 10MM in width and the height would be negligeble as the ratio hasnt changed much being both are a 60 series tire. I do not believe the difference would bother the speedo as they are usually off a couple of MPH either way from the factory. I went from a 150 to a 200 on my other scooter and there was no noticable difference in the tach vs speedo. the thing to look out for is the load range between the two tires and the speed range. I was going to go with a wider tire on the Ultra but opted to stay stock as the load dropped by more than 200 lbs per tire going to the wider one.
