"The bigger tie rods should wear longer under the higher g-loads"

That right there I think sums up the herd instinct on this topic. First I suspect the robustness between the two choices, shooting from the hip, I bet approaches 40%. But I think it it is a pretty big misconception TR's take any significant cornering loads (g-loads) in the first place. And oem size TR's last for quite a few miles on the street, pot holes, curbs, slow speed parking ( highest loads on TR's likely, without a, IMO, a high wear concern, so extending it, if we use the 40% factor, and not sure if that would be linear, we really don't have any need to for longer wear cycles. I could go on.

I'll add lastly, because invariably someone will, "it doesn't hurt"
