I'm not going to agree with this either. I weigh about 240, always ride 23's with about 100-110 lbs. pressure and have never had any problem. I don't know what any "chart" says - I've never seen one, but I do think that if this was going to be a problem I would have discovered it by now. I've been riding these since the 1970's. In your defense however, I will admit that when I know I'll be riding on rough, dirty urban city streets I do ride 25's, but this is primarily for more flat protection. Somewhat off topic, but related - I do ride sturdy wheels. Almost all my rear wheels are 36 spoke, 14 ga.

I hear that a lot but I have doubts. Do you have an industry source for that statement or is it just rumor?

If true, there should be a test protocol document somewhere that specifies what kind of rim tires are tested on.

I am also a clyde... Well a pachy.

I've been told the rims can also only handle so much pressure. This was dependent upon pressure, tire width, shape and rim characteristics...
