Personally I'd just buy something in the right size and have at it.

I agree with this, plus disc brakes have a bad habit of warping and then just being a pain to deal with.
And tires wider than 25 or 28mm aren't "needed" for someone in the 200+ lb. range, for example: I rode 25mm tires at 230 lbs without an issue, though I now ride 28mm at 180 lbs, due to slightly more comfort, and traction on rougher gravel terrain.
I don't agree with this; I'm 200ish lbs and found my 28mm road bike tyres were awful (because they were at 110psi so like concrete). I've moved to a bike with 40mm tyres (at 60psi) and so much more comfortable, but the roads are awful here.
