Last weeks thread here

Welcome to this week’s casual kōrero thread!

This post will be pinned in this community so you can always find it, and will stay for about a week until replaced by the next one.

It’s for talking about anything that might not justify a full post. For example:

  • Something interesting that happened to you
  • Something humourous that happened to you
  • Something frustrating that happened to you
  • A quick question
  • A request for recommendations
  • Pictures of your pet
  • A picture of a cloud that kind of looks like an elephant
  • Anything else, there are no rules (except the rule)

So how’s it going?

    Thanks Google/Dave! - 0.6mm is a wild amount of wear but they are racing the shit of them…

    Are you endlessly curious or something??

    I did find this pdf from an nzta page that suggests there’s a range of tire sizes available that a given wheel can accommodate (within their range of tolerance as well): https://www.lvvta.org.nz/documents/infosheets/LVVTA_Info_01-2009_V3_Tyre_Size_to_Wheel_Size_Compatibility_Guide.pdf

    The 2nd page is a big honking table of different sizes, profiles and rim widths, so I gather there’s a degree of anything goes and maybe next time we wear ours out, I’ll try to be a little more attentive… Maybe I can get some accurately sized ones (probably not worth it - getting pinged for going a few kmh over the speed limit would really suck!)

      Haha I think I might be!

      I did find this pdf from an nzta page that suggests there’s a range of tire sizes available that a given wheel can accommodate (within their range of tolerance as well)

      I’m afraid I don’t understand that table. There are no units listed, and I don’t what what measurement the range is meant to represent. If the tyre width is 115 somethings and the profile is 80 somethings, then there’s a range of 3-4 somethings. But what measurement is that talking about?

      Given that the 6.5mm is about 1kph from the above calculations, I’m guessing similar tyre sizes probably still don’t change it by more than a couple km/h.
