If you run the DWs at the same PSI you ran your stock tires at, they blow.
Bump them up to 40 PSI.
I run them at 40psi. The problem with 40psi though is they wear the center rib down much quicker then the outside ribs. I got two summers out of them, they are not worn out yet, W is still visible but I have to replace them due to the dry rot and disappointing driving characteristics. Its bad when my snow tires don't feel like that much of a drop off as it pertains to sidewall roll.
