These are 175/65-15 ( using 17 PSI ) on the FRONT of my ( basic ) 2014 RT .... I put these on 9-30-16 @ 26831 mi. and the Netzley's did a Lazar alignment the next month ..... Now I have 51,799 mi. so = 25,000 +/- to date .... how are they wearing ??? ... since I will re-place before they are bald, I measured from the WEAR bars inside the tread .... they are wearing equal across the tread .... got 3.1-2 mm (0.12 in.) ..... the total tread depth 5.1mm (0.20 in. ). so I'm quite happy with a very sticky tire ( wet & dry ). I didn't measure them when new .... I will when I re-place ..... Mike
