Yes, Hawaii does have horrible roads, but, I hate to say this... (knocking on wood) I haven't hit a pot hole in my Tesla SO FAR...
I have been driving a Tesla since 2014, with the 19" rims, 21" Turbines, and never had any issues till I mounted the Arachnids, just about 21 months now, and almost 20K miles...
So yes, I think it is weaker, but, no one is going to admit that... and yes, both my cracks looked very similar to the pic above it leaks air very very slowly.
Have a great day!
