Tire Liar (s) Size matters!

I'm tired of buying tires that are not what they are advertised to be. Today I had to return a Maxxis mobster 2.7". 2.7" yeah right.... after I mounted it up (yes yes...on a fat 44 mm rim) and measured it, it was barely a 2.35". Geax tires are dead on. If they say it's a 2.25" it is. WTB sizes are inaccurate unless you look at their millimeter measurements- those are closer. Their 2.4" motoraptor (great tire) is really a 2.25" by my micrometer". The mutano raptor is even further off. I don't trust any manufacturers (cept Geax) anymore. It's like the fork weights in the early 90's. I'm wondering whether anyone has put together a webpage or something that details the TRUE width of tires. What is the fattest kevlar beaded tire available?

44mm is not a fat rim. Had a 26x2.3 Geax that measured to be about 2.0 and have had 2.7 Maxxis High Rollers that have Measured out to be from 2.35 to 2.8. My current setup measures out to be 2.6 and 2.3. 26x2.5 Michelin Comp 24.1 and a 26x2.2 Michelin Hot S.

The company that is notorious of having their measurements way off wack is Continental. Their 2.1's are the only accurate size. Their 2.3's run like 2.0's their 2.5's run like 2.1's their 2.0's measure like 1.8's.

Their is no standards in tire measurements, each company has their own way of measuring the size of a tire.

not fat?
I'm not aware of many rims fatter (wider is perhaps the better term) than 44-46mm. Mine are snowcats. Surly Large marge, Sun doublewides, Atom bombs, Remolino sand rims are all wider. Are there more? If so are they light? I don't need downhill strength.

DeeMaxx's, Halo Combats and a few others, will post those when I remember them. Old DeeMaxx was 50mm pending on year.

To reiterate. Tire sizes vary greatly. I know on my singletracks the 2.7 mobster is around 2.6. Highrollers measure really narrow on my ryno lite and come in around 2.2 in actual width. No standard way to measure and every company is different. My tioga 2.1 was bigger than my high roller 2.35

If you really want a fat tyre then check out the Panaracer Fire FR's, the stated size is 2.4" but i know people that ride 2.6 or 2.7's and they're no bigger than than my pannys. Have a look at this site for some seriously good info on mtb tyres. It gives you all the size and weight info you'll ever need.
