Hi,
I got PR2 installed to replace OEM's. What a difference and improvement ! Most of the mileage I've done with the PR2's was with saddlebags and Givi E55 top case full. Add the passenger at the back and that makes a good load. I did a lot of twisty roads, nothing excessive... and after just about 5000 kilometers, I noticed the rear tire had some wear on sides compared to the middle that was like brand new. I think and I'm sure that my mistake was running them at 42/42 when loaded. My dealer's service guy told me this was a sign that the tire's pressure was too low. He says that I should go to 45-46 psig when fully loaded. I consider the fault to be mine, I should have... So, I'm replacing it.
I'll have a 190/55 PR3 installed next week. I don't want to repeat the same mistake. What pressure would you recommend for the fully loaded C14?
Including me, passenger and all bags full, the load is surely about 425 pounds.

Let's see, you do curves and there is wear on the sides, and a dealership tells you you under inflated the tire. Hmmmm... yeah, no. Besides, the engineers recommend 42/42. If you look on the sidewall of a PR3, it says, MAX LOAD 805 lbs at 42 PSI COLD.
I got over 8000 miles out of the front OEM tire and over 10,000 miles out of the OEM rear tire. There was a lot of long distance interstate riding on the tires, but I live in Pennsylvania and traded an RC51 for this, so there was a lot of fast riding in the curvy roads here and in West Virginia.
I keep mine at 42/42. Using the engine as a brake eats the tire more than almost anything else including fast starts.
