diameter and load capacity 200

Assuming the same tire model and the same max sidewall pressure, load capacity will be the same when overall diameter is the same, and will increase when diameter increases. In fact, checking ratings across different tire brands and models, the only variables that significantly affect load capacity are those two: overall diameter and max sidewall pressure.

Which is why I'm always after getting a tire with the right overall diameter. Load capacity and speedo/odometer accuracy. Sidewall pressure will be one of two or three commonly used ratings but "casual" size selection will be inaccurate.

Which means that if you match the OEM diameter your speedometer will not lie and your load capacity will be as the engineers intended.
