Update: Blew the charge pipe, running 17.5psi. Replaced it with a BMS metal one. Still no other issues. Just started on my second set of tires with 23000 miles on the DW's. Rears were worn to the wear bars but fronts still had at least a winters worth of tread on them.
Replaced the fronts only because of a patch plug very near the sidewall that had a slow leak. Was the second patch that leaked. The hole was too close to the sidewall & the flexing was pulling them apart. Not worth the risk when you don't have a spare.
