    How did you break it?
    What tyres are you running?
    What tyre pressure are you running?
    What style of riding?
    How old are the wheels and how active are you?

    Most likely from catching some air.

    35 psi

    The wheels are a few years old. I'm doing around 50 miles a week.

    Good job!

    hhhmmmmmmmmmmm

    Mavic EX823 36 or 32 hole
    Hope Pro 3 hubs
    Sapim CX-Ray spokes
    Brass nipples
    Hand built with a high spoke tension (not a factory build)
    Serviced every 6months by the wheel builder to ensure spokes are in good condition and rims are true

    These should last you a lifetime....

    I am also 250lbs and 6'3". For UST on my do-it-all bike, I decided to build a rear wheel with a EX823 (with a sturdy also) instead of a XM819. If you are bashing and getting air occasionally, 823 will be more secure at your weight. I use 819 for the front, and for F/R on my XC hardtail.

    Yeah, fairly heavy, but, then, so are we.

    All the spokes in the world won't stop you from cracking a sidewall. I had some 717's do that. The fatal failure was the spoke bed splitting lengthwise between three spoke holes, but the sidewalls were cracked on both sides along most of the circumference of the rim where the sidewall meets the middle section of the rim.

    In my case it was me running too large of a tire at too high pressure. I was running Nevegal 2.5's over 40psi and weighed about 280 to 300lbs at the time.

    The 823's are 205g heavier than the 819's and the tire size recommendation for the 823's is 2.3" to 3.0".

    At your size and riding style, if you're determined to run a Mavic tubeless rim, I would go with the 823. Laced with 32 Sapim 13/14 spokes to a Hadley/CK/DT-Swiss rear hub, and I think you'll be good to go. 36h wouldn't hurt, but it doesn't seem like that is really your issue.
