Can I put my 2.1" 29er tires on a wheel with 25mm inner diameter? So I broke my second front wheel last night when I hit a dip that rose too quickly for my wheel to climb before all my weight went behind it. I'm a big guy (300+ lbs), so my wheels need to be able to take a beating.

Right now I have a 2014 Specialized Rockhopper Comp 29er with the original fork, tires, and just about everything except the peddles and wheels. I upgraded to Mavic CrossOnes last year after I taco'ed the original front wheel on a hard turn.

I am getting tired of replacing these wheels. It is getting a bit expensive too. So I want to find some really tough rims and from what I read you need to get wheels that have a wider inner rim. The Mavics are 19mm if I remember correctly. 

I am thinking about upgrading to a DT Swiss EX 471 29er rim which has a 25mm inner width. But I would like to stick with the ground control tires I already have and really like.

Would my 2.1" Ground Control tire work on this wider rim? I am also considering going tubeless. Also, any recommendations for stronger wheels for my heavy body?
According the Sheldon need 25mm for a 2.1" 

A downhill wheel tends to be strong (and heavier)
