Dear fellow gravel grinders,

I have decided on the 43 Gravelkings, and was wondering if they would do fine/excel on a 25 mm internal rim width? I am a bigger guy (180-190 lbs, 6'4"), and my only experience is a 47 WTB Byway on a 23 internal rim width, which runs great for me. I am in doubt, because the 43 Gravelking SK's were orginally called a 40 mm tire, and according to the safety charts of Mavic and the likes (http://engineerstalk.mavic.com/en/the-right-tyre-width-on-the-right-rim-width/) I should not put a 40 mm tire on a 25 mm internal rim width. The only options within my budget are a 20mm internal rim width and the 25i one 

What internal rim width do you prefer for 40-45 mm tyres?

They'll be fine, don't over think it. We used to run 2.4s on 17mm rims.

Agreed, they will be 100% fine.  For reference I used 42mm WTB Resolute on a 26i Enve M60HV at LandRun; A-O-K all the way!

I ran these tires on i25 rims and they were perfectly fine tubeless. Not a problem to run these tires on a rim with this width at all. It will have the effect of slightly flattening out the "crown" of the tire, but for gravel travel where I am at this is actually a good thing.

I run GK 43's tubeless on Velocity Blunt SS (26.6 inner) with no problems.

Should be more than adequate - I run 40s on 22mm internal which is a huge rim to me!
