I have been needing a more mud-friendly tire, to replace my worn gravel tire,for the spring conditions in the wheat fields. Searching my stash I found these, Bonty Jones Mud X 29x2.0, tubeless ready. 17-18-ish years ago they were great winter MTB tires for the Oregon Coast Range. Now they are basically a large gravel tire. The 47/49 on the side wall was the “Global Measurement System” sizing introduced by WTB. 47mm casing width, 49mm tread as measured on a ~20mm (26mm external) width rim at 60(?)psi. I measured 49/50 at 30psi on a 22mm rim.
I remember those more from a different time in our local relationship with Trek and racers who would hammer on our trails with dirt that doesn't handle rain very well. I'm very happy to say these days lots of Trek staff are good members of their local community and they have a lot of good products too. They do some advocacy and giving all over but I thought folks not near them might know they have a noticeable part of their staff who are hands on and giving in their community. In this era of big events and sanitary trail, their MTB and engineering group participates in old school build by hand stuff.
My closest to something like that is/was the 48 and 55 mm wide RH knobby tires.
