Does anyone have experience with Toyo Proxes tires on their Z? Have 235/40/18 Falken 452s now and they are "cupping" in about 10,000 miles. Thanks for any input.

well you learn something every day... 
"Cupped tires are most often caused by bad shocks and more so by bad struts.
The purpose of the struts is to keep the tires from bouncing off the ground when you go over bumps. If the struts are really bad, the tires can literally bounce up and down like a basketball, and each time the tires hit the ground, a little bit of the rubber gets scraped off. Eventually, you get a lot these little scuffed spots, and that's called "cupping."
Cheap tires cup more easily than good tires. Make sure you replace them with good, name brand tires."
