Fronts 245/35ZR20, rears 305/30ZR20. These are OEM - N spec with about 50% tread left - new tread depth is 10/32" these have 7/32". The manufacture date for the fronts is Dec 2013, the rears are dated Feb 2017 and were installed as part of the CPO inspection prior to my purchasing the car in April 2018. Replacement cost is over $2000. Why am I selling them? Prefer Michelin PS4S and estimate it would take me at least two years to wear these out. Selling as a set $800.
