I'm curious if anyone is running the combo of a 29x2.8 tire on a Velocity Blunt 35 rim (30.2mm internal width)? How has that worked and what does the actual tire width end up at?

I am running 29x3.0 Fat-B-Nimbles (tubed) on the Blunts now and I end up at 2.7" (measuring on the outside nubs). It is tight in the frame of my Ogre and I occasionally get rubbing, so I'm looking for more room.

If a 2.8 would bring the real world width to 2.6 or 2.5, that would probably work better. Or a 2.6" tire that is actually 2.6 on a Blunt would work too. Or I get a different frame if I want to run 29x3 (I have another thread on that).

Thanks!

There are folks who do this and seem to like it, me myself won't run anything past 2.5" on an i29/30 rim and even then depending on which 2.5" would prefer it on an i35. You're lucky in that I just received my 29x2.6" Nobby Nic Apex SG tyre this week and have mounted it to an i35 rim, after leaving it overnight to stretch it measured a bit over 67mm at 35 PSI, dropped down to riding pressure (17 PSI), it still measures 65mm.

It's going to highly depend on the tire. Some run small, others right on. I've run numerous 29+ tires on Blunt (P35) rims. No issues. And I've run some chunky trails in Moab and Southern Utah.
Most tires were right on as far as width. I would try to get some hands on 2.6" tires and see if that works better. If it works ok, you can always go i40-45 rims and fatten them up.
