I am a old retired geezer also, normally ride 2 up, I am 225 ready to ride wife is 150 ready to ride and we live in Arizona (it is a dry heat), speed limit freeway 75 most other roads 65. Generally run speed limit + 10 or 20 depending on traffic road conditions and bears. Longest trips taken San Diego and back solo 1,000 miles, Laughlin, NV. 850 miles 2 up + bags, Prescott, AZ 600 miles 2 up bags loaded. Was very pleased with the Pirelli Angel GT spec A but really like the comfortable ride of the Metezler. Since Pirelli and Metezler are both owned byChinaChemCHEMCHINA a state run company an interested in how they last. Both tires are HWM, rear made in Germany front in China.
I did 18000 miles on Michelin Pilot Road 2's on a lighter bike, a 2003 Triumph Sprint ST. Mostly highway riding at 80 mph on interstates. The front had at least 2-3k miles left. I have PR3's on my Concours 14 so I hope to get 8000-10000 miles (not easy based on what I read).
If I got 6k out of PR2's I was happy. Not sure how you do that. If you're happy, that's all that mattersI do not do anything different. I have destroyed tires in the past by leaving them under-inflated by just a few psi so now I meticulously keep them at factory recommended pressures and check them weekly. Riding is on the conservative side most of the time with early braking and smooth acceleration. At curves I let the bike to show me which speed it likes if you know what I mean. I do push the bike over its limits at curves and of course I get "chicken strips" eventually.
