After talking with several tire people, including Dunlop customer service, I'm convinced you're absolutley correct in running the higher pressure. I checked the pressure from the dealer and found they had placed it at 35. I will be increasing the pressure. Pressures as hgh as 39 with monitored wear were recommended. Your 36 sounds like a good starting point. Dunlop customer service had reommended a little different rotation frequency than MB's. Something like a 6000-3000-3000-6000 and on. Thanks for the input.
