Re: Bad Metzler 880
I had the same thing happen during a trip around Australia. My failure was on the RHS with 5 blisters that the tops had ripped off. We drive on the LHS of the road. Was very hot, pulling a trailer and not hanging around either. Metzler replaced it no charge after I got home. Another few k's and it would have popped!
Looking at your picture which is very dark, it looks as if you have bad assymetrical wear on the tire. Are you towing a trailer at all.
I am half way thru another Australian tour and after the bad experience with the Metzlers have a set of BS 020's fitted. Again I am showing wear, only nowhere as bad. As we have been riding for the first 2 weeks into wind from the RH quarter, I suspect that the lean of the bike into the wind, and maybe the trailer acting as a sail, is promoting this wear pattern. I still have about 6000k's to go so I will see how it pans out. The last week has been nearly no wind. Amazing the difference it makes to fuel consumption!
I normally run 42/48 psi front and back but have reduced the rear slightly as heat build up takes the pressure over 50 psi - beyond the design limits of the tire.
After the last trip, I now run the back wheel without the spacer, making sure that the wheel does not rub on the swing arm. This has also reduced the RHS wear tendency during normal riding. I can ride hands off now, where as before there was always a tendency to pull one way.
Discount all the camber of the road arguments, as to achieve the angle of wear, you would have to be riding on a very highly cambered road for extremely long distances.
I have tried to attach a piccy of my tire - hope it comes thru.
I believe the Bridgestones have a 48 psi max as compared to 50 for Metzeler.
No need to adjust for temp induced pressure rise. The tire maker has already done that. You can inflate to the max pressure as long as the tire is cold. No need to worry if hot temp pressure rises above the cold inflation max.
