Max tyre width on 17mm rims?

[sometime]

Hi,

 

I'm looking to fit wider tyres than my current 26 x 2.0 on my SS. Rims are DT Swiss XR4.1 with an ETRTO of 559x17. i.e. 26 inch rims 17mm wide. I'm running a rigid steel fork so am looking for some volume and width to provide some cushioning and grip. There's no problem with tyre clearance so I could run 2.4's like the Conti XKing but my concern at that width is the rather narrow 17mm width and if I'm going to have any problems with the wide/narrow combo?

 

Googling reveals no max tyre width for these specific rims, but differing opinions from other rim manufacturers with the general opinion being 2.25 as the max. I currently run Schwalbe Nobby Nic and Racing Ralph 2.25's on my 29er. I really like these tyres so would be keen to run these on the SS, but locally these seem to be available at a max width of 2.25. Schwalbe's website suggests a max of 2.1 on 17mm rims.

 

Anyone have any personal experience with tyre widths on this width of rim? Thanks

I wouldn't go bigger than 2.2.....2.4 may pop off in the corners.

I have a wheelset built with the same rims. Personally, I have run 2.1 tyres on these rims, but I wouldn't run anything wider, as the tyre bead doesn't hook fully into the rim. I have rolled tyres off the rim (with tubes), so would say that 2.0 is the max width I would safely ride with.

Thanks guys.
