Mefo Tires Okay On A Tubeless Rim Ural?

  • Anyone know any good reason not to use Mefo Dual-Sports or Mefo Super Explorers on a Ural if I get the rims sealed for tubeless by Woody's Wheel Works?

The shape of the bead on a tubeless rim is different than on a tube-type rim. As a result, the shape of the tubeless tire bead is different from a tube-type tire. Nevertheless, it IS possible to get a tubeless tire bead to seal on a TT rim, though it will never be an ideal seal. Your concern, though, should not be if it will hold pressure, but -- will it explosively deflate when the bead breaks under stress?

Quite a good discussion here -- http://bmwmotorcycletech.info/section6.htm

If it was me, I think I'd rather spend a few extra bucks and have Woody lace up a proper tubeless rim to my Ural hub if I wanted to to use tubeless tires.

Also, you specifically ask about Mefos. I think that Mefo conforms to industry standards when it comes to the shape of their beads. So your question should not be "Mefo Tires Okay?" but should be the more generic question "Tubeless Tires Okay?"

You also need to check the load rating for the tire. Sidecars need a stiffer tire for the side loads. I believe Ural calls for a 4 or 6 ply rating.

Have you had Mefos? I had a set on my KLR rig ,which was not as heavy as a Ural, and they did not wear very well.

I tried one on my KLR Rig too and a $40 Kenda Knobby lasted over twice as long as the Mefo. Matter of fact I got 14,000 miles out of the Kenda on the pusher.

Our GU-11 came w/ 6 ply tires from the factory. Much like.
