so heres what happened in the end, the tires are Dunlop and I called customer service Goodyear/Dunlop corp. nice lady says that I am still under the wearout warranty 60k miles and they have shops that will patch/plug FREE! so I said [censored] yeah where do I go, they sent me to a GOODYEAR service center bout 10 miles away for an appointment. so I got there this morning and the manager already was waiting for me, and I re asked I said this service is completely a free he said yes completely. so I wait in the waiting room manager comes back says they found a nail but the tire is not repairable? whaat the nail was too close to the inside edge and couldn't be repaired by them and I had 2 choices but 1 new replacement tire which he recommended that I buy 4 new tires cause the truck is a 4x4 and could effect the transfer case whaaaaaaaaaat! so I said show me the nail, I said to myself this is a 100% pluggable in my limited plugging experience so I said thanx but no thanx, stopped at AUTOZONE PICKED UP slime CEMENT and 5 new SLIME plugs=$9.57 and plugged it this afternoon in my driveway. now ive aired it up to 34psi and hope it holds up, looks good so far, my fingers are crossed. also the tires are only 50% worn at about 50k miles says the manager there, so no way im springing for all new tires or even 1 new tire. probably a bait and switch deal where they can throw unknowing folks under the bus when they don't need to on repairs to suck up some sales revenue/commisions.
