2/9/2020 Update:
Officially an owner of a 2011 R3R! $6250, so not a full set of new tires, but at least get the rear done. I'll post pictures tomorrow since it's now too dark to get any good ones.
Nice!
If you go to @idk signature you can see a link to docs including the recommended maintenance schedule. You can use that as a guideline to see what if anything you may want to inspect/replace based on age.
