2023 Spyder RTL, 20200 original miles, Kenda OEM front tires. Both front ties showing equal amounts of cupping on inside and outside of tire. Tires close to replacement as per wear indicators. Tire pressure diligently checked, no abnormal steering, handling or braking difficulties. I do not ride aggressively and occasionally will have someone occupying the seat behind. Noticing various complaints regarding Kenda tires - is this something that goes with the brand?
