I've got the stock square setup with 400M ET34 wheels. I upgraded from stock runflat 225/45-18 to 245/40-18 Michelin Pilot Sport 4S. Great handling! Always important to keep air pressures correct.

The square setup allows me to rotate them front to rear. I've been taking tread depth measurements across the tread every time that I rotate them. Wear has been very even. I estimate that I'll get at least 20k miles. A big plus that people forget is that with rotation the car will handle consistently throughout its entire tire life. The fronts or rears won't wear out sooner causing a handling deficiency.

Hope this helps!

Perfect. This is exactly what I was looking for. I'm strongly considering a 245/40-18 square setup. What pressure are you running? I feel like I've never been able to get the tire pressure right going from run-flats to go-flats. What are the differences you feel from the stock setup? Any negatives?
