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,

I can't see anything worrying in that pic. What abrasions are you talking about? Any rim brake bike will have some rim wear. As long as braking is smooth, it's basically ignored until the time comes to replace the rim.

I had to deflate the tire to get a good pic, but this is the abrasion I'm referring to.

Tires and pads, sure.
The rim is fine.
Treat yourself to a tire upgrade, you will most likely increase your use/enjoyment.

Hope this helps, welcome to the forum.

Ah, I see.


Doesn't have to be bad. But I can't really tell.
There's often a cloth strip securing the bead to the carcass of the tire. A little fraying along the edge is common. If that's what it is, it'll be fine. Bulging is the key thing to watch for.

If the brakes are tearing into the side of the tire, then they are adjusted too high.

Move them down slightly on their mounts.

The rim should be fine, unless it starts looking a bit concave from lots of wear. If the pads pick up little bits of metal or rock they'll tear up the side of the rims, but usually it is just superficial.

Replacing the pads (and making sure they're adjusted properly) is a good idea.

For replacement brake pads on rim-brakes, I personally prefer these Kool-Stop Thinline's, the vee'd shape of the leading and trailing edges help to keep the pad from picking up as much debris, and therefore don't lead to scoring of the rim as badly as normal "square" pads. Plus they just work great and last seemingly forever.

Thank you all for your replies and advise, I have replaced the tire, tube and brakes pads. When the weather gets a little better, stops raining, I plan on getting some riding in down by the ocean.
