Hi everyone, this is my first post and I have a question about my tires and rims.
I have a Diamondback Insight 2 that's been in the garage for about 2 years. I started cleaning it up and noticed some abrasions on the rear rim and tire. I'm replacing the tire and brake pads, should I also replace the rim? And what causes these abrasions? Am I doing something I shouldn't be?

Thank you in advance,
Shortfuse
