Bought our 14000lb 5er used in spring of 2014. It had CarlisleRH tires date coded ~2012 at the time, no idea how many miles. We've put 19,000 miles on since getting it, kept tires aired to 95psi (load range F) and have had no tire issues. Have planned on replacing next spring on time.
Just had bearings greased and mechanic said I had alignment issue because all 4 tires had significant and irregular wear on inside AND outside ribs, 3 center ribs no significant wear. All 4 tires like this? My first thought is underinflation but have TPMS so I know inflation is 90-95 cold always (TPMS reads ~3psi lower than digital gauge).
Hard to believe it's alignment as new MorRyde IS installed 14,000miles ago and all 4 going bad? And both inside and outside rib wear on same tire caused by alignment?
Taking it to MorRyde in a couple months and see where I go from here. Like the 3900lb carrying with 95psi instead of going to 110psi (more damage IF blow) so still planning on replacing with RH but want to discuss with MorRyde first.
