thanks Mr C, didnt look.

re tire widths, using 35mm or even more can have the benefit of being a little easier on the wheelset because a wider tire at lower pressures has more "give" and "suspension" , which means less harsh forces going intothe wheels.
As a counterpoint from my experience, I have toured in Latin America using 2in tires, which on my rims measure out to 45mm, slicks, and for the road conditions I was on sometimes, wider was great and made life easier for my rims (26in wheels) and spokes.
In town, I ride on a couple of bikes, one with 38mm (1.5in) tires and another with 35mm. Both are easier over rough pavement, of which here in Montreal we have a lot of, and both roll along nicely and are not too wide. Given you are heavier than I, at least a 35 will be easier on your wheels, which is a good thing, and like I said, they roll along fine.

I hope others close to your weight can chime in, although do be aware that how you ride makes a diff also, ie not bashing over potholes too fast, or always staying in the seat when going over rough stuff, this all puts more forces into wheels in general.
