Ultradynamico 650b Tires - Actual Widths? or Mixed Terrain 650b Tire Recs.

[David B]

I'm in a current search for a new 650b tire. I was using WTB Byways, then Horizons, but want something that geared more towards dirt than pavement. Local trails around me are a combination of dirt and gravel and my specific area is not as well maintained than other sections of a longer trail that I typically ride, so lots of tree roots, some rocks, &c.

I'm curious about the Ultradynamico offerings and would like to test them out if they're no larger than ~47 actual width.

That's about as wide as I can fit in my Redwood with fenders.

So, anyone running the Ultradynamico tires and care to share actual widths? My rims are ~25mm outer width (~18/19 internal).

Or, any recommendations for a mixed terrain tire in an actual width range of 43mm - 47mm?

Thanks,

David
