With larger tires, more caster, etc you will increase the overall pressure requirement (i.e. you make the duty cycle more severe by some amount). However, the maximum pressure is regulated by the setting in the flow control valve that is inside the pump. Corvette settings are typically quite low (1000 psi) compared to most other GM vehicles. So as long as you haven't put a power steering pump (or a flow control valve) from a truck or big passenger car in your Corvette pump, I doubt that your bigger tires are the cause of the assist cylinder failure.
Typically I have considered the power steering pressure hoses to be the weakest link in the system with respect to hydraulic leaks.

The max pressure is the same regardless of the tire size.

Hey Jim, I been meaning to ask
what is the difference from vehicle to vehicle useing the same type of pump? The valve itself, the spring? Besides the obvious resevoir differences I mean
thanks
Sorry for the hijack
