tires. Please explain 29" ?

They're the new larger size mountain bike tire. The other ones looked too small when the bike was
hanging off a Humvee or Escalade.

Oh, it's very simple, you see. How it works is that nothing makes sense. The labels are not in
any way related to the actual size, nor are they proportional to other labels. So, what you
need to do is:
1. Take some LSD
2. Chop a tape measure into one-inch lengths
3. Drop the bits into a hat
4. Pull one out
5. Read to grok the meaning of tires, the universe, and everything Or, just go to
sheldonbrown.comtire sizing.htmlOpen ↗ and remember: Only in tire sizing does .75 not
equal 3/4.

29" tires are, if I understand correctly, mountain bike tires that fit wheels designed for 700c
tires, which are larger than 26" but smaller than 27". Got it? 26" is smaller than 29" (which is
equal to 700c) which, in turn, is smaller than 27". Only in tire sizing is 27 greater than 29.

Attn Sheldon: Time to update that tire sizing article to include 29" tires.

I believe the so-called 29" MTB tires are fat tires for 700c wheels (which are actually 622mm
diameter bead seat). The idea is that the outside diameter of the tire will be around 29". The older
27" road bike wheels are actually 630mm diameter at the bead seat. So a 27" rim will be larger than
the rim for a 29" wheel, but the outside diameter with the big tire will be larger on the 29".

Thank you, thank you all. Your answers make sense to me. Guess I'll just pop another beer, and be
glad my tires hold air. chls
