My first spyder was a 2016 rt SS se6. I only got around 8000 miles front and back on original kenda oem tires. Now fast forward . I now have a 2018 f3s se6 .Rear tire as normal lasted around 8000 miles, but I still have the original kenda on front I now have 16000 miles there is no cupping or ride handling issues and ride fairly aggressively. (Hence trade from rt too f3) I purchased my replacement tires months ago. Is this typical for other riders? I will be replacing the rear tire again this week. And still on OEM front kenda.
