I find my 2019 XTown 300i very tire sensitive-----today, ride on TN rural/high crowned road----all over the place going straight: reason, front OEM tire, 10,000 miles wearing square on the edges---ok going down the Freeway or for that matter leaned, over 30 PSI. So time to change....I usually get 15,000 miles or so from front scooter tire---Had been planning on matched pr of Michelin Power Pure SC....but? May try front Heidenau...had good luck with them in DDR days on my MZ's. I want to pay about $60 for front tire. I for the past 10 years have used "Ride On" as balance medium with great results!! My front wheel have a lot of balance weights----will check on my balance stand once tire is removed, and see if was the tire out of balance or the wheel.
At about 3,500 miles I replaced rear OEM tire (worn square) with Michelin City Grip, now with less7,000 miles it is starting to wear square, too. City Grip for me nothing special, especially with no proper size front available. Best for me, probably Michelin Power Pure SC----wore round and got over 10,000 miles rear on Burgman 400.
Stay tuned to see what happens.
