My Goodyear Endurance served me well but only for about 8000 miles. Leaving for Montana from FL and they have 3/32 remaining and need to replace I have 235/80R16s for our High Country HM318RE. Considering the Sailun S637 but they are rated for 110 psi and my wheels are rated for 80. I’ve seen comments about inflating the Sailuns to 80 but all I’ve read highlights that under inflation is a major cause of tire failure. I’ve run the Goodyear’s at 75 and never had an issue. Seems to me that inflating the tires to 80 when rated for 110 would be major under inflation. Is that a valid concern and would I be buying myself problems?
