90 psi doesn't sound like enough if you're 400 lbs. I'm not sure, but I would try 110 or 120. These are 26x1.5 tires or something like that, right? More pressure in your tires makes your rims and spokes last longer. Wider tires help, too.
You do realise that rims are designed for a certain amount of pressure and exceeding it without reducing tire width, can cause the sides of the rim to bend outward, destroying the rim. On a bicycle with rim brakes this affects the braking surface and can result in brake failure. One should always check the specification for the rim and tire, while you can exceed the maximum pressure rating for a tire, nobody really knows (except possibly the tire manufacturer) by how much. One 90PSI tire might be happy at 120PSI, another one might not.
