I've had my 2021 RT for almost 3 years, and I'm just short of 12,000 miles. I plan on getting an appointment for an oil change and service and wondered about tires. The two front ones look like they are still brand new. The rear tire looks a bit worn but still has what appears to be a lot of tread left. I don't baby the RT when I am riding, but I don't claim to be the most aggressive rider. I probably spend the most time riding at speeds of 55 to 65, and have yet to have the nanny kick in. I'm wondering if I should just go ahead and get a new rear tire put on since I am bringing it in for service anyway.
