Too-fat tires on narrowish Mavic rims?
Van Bagnol
on a pair of new Mavic X222 rims. I just discovered through a product
brochure that Mavic recommends only tires from 1.5 to 1.95 for their
cross-country rims.
What is the effect of having tires this far past mfr recommendations?
The wheels are intended as my set for riding on road, though I may
take an occasional detour through hardpack/fire road.

I ride with Panaracer FireXCpro (2,1) tires on my x222愀 - it愀 no problem,
at least I haven愒 experienced any. Before that I had IRC Mythos XC (1,95)
tires and I honestly can愒 se any difference concerning the rim - but the
FireXCpro愀 are way better and shed the mud really fast :-)
Kind regards

run Ritchie 2.35 Z-Max tires and found that on the 222 rim that, if they
were the least bit soft, say 35 - 40 pounds air, they would fold or roll
heavily to the side if I landed a jump without the front wheel perfectly
straight forward. I'm not talking giant jumps either. The tires beads were
just too close together to properly support the bigger tire. That's why the
rim manufactures issue tire size limitations. I like to run a softer tire in
technical and real bumpy stuff. Even with good suspension, which I like to
run a little stiff, a bigger tire, run a little soft, really adds to a tight
hookup to the ground and roots are almost imperceptible. Yet the bike
doesn't mush all around. I run a Mavic D521 which a somewhat wider than
normal and really tough. Since going to them, I don't ever have to retrue my
rims either, they just stay true.

I wouldn't worry too much about it. The difference there is minimal. I've
run the fattest Bontrager Jones rear tire on 21-22mm Mavic and Bontrager
rims. The most trouble I had with larger diameter tire and narrow rims is
that the arms on the original Avid V-brakes would touch the outer tire knobs
when I used Kool-Stop pads on them. The original pads and Shimano pads were
OK (they're much thicker). That's another reason I switched to XT v-brakes
which, by the way, I really like. I had more trouble with noise on the
Avids than I do with the XTs. They're the infamous '98 models to boot!
I did have trouble with a really fat WTB Tyrannoraptor that had part of a
bead come off a rim after a little wipeout. I don't know if it was the
crash that caused the tire to roll off or the tire rolling off caused the
crash but the bead on that tire was much looser than other tires I've used.

I haven't used my FireXC 2.1s for a while, but if memory serves they're really
only 1.9" or so at the widest point, so they shouldn't exceed the rim's specs.
Not sure why tire manufacturers to this, but their claimed widths are often
way off. I had some light Nokian 2.1s that only measured 1.7 across.
The odd thing is that many tires come with both inch & metric measurements,
and the metric measurements are generally smaller, and closer to reality.

1.95". Now, if the manufacturer specs it to a 1.9" tire, do you really think
that the extra 0.050" makes a crucial difference, you can't even see the
difference and have to measure it to know it's even there!!!!
