16,500# 5er sure does not have 4,125# on each tire. Did you forget to subtract a minimum of 4,125# for the pin and most likely more?
Too funny as all I ever heard was the ENDURANCE was not on the mArket long enough. Back then the “THIN” tread was NOT an issue. Then a few years later the tread all of a sudden became an issue and that is all that can be said since the ENDURANCE has been on the market with a STELLAR RECORD for five years now.
Looks like a "Moderator" edited my post??????
Looks like I figured 25% pin and I should have used 20% that would be 3,300# and that would leave 13,200 on the axles divided by 4 would leave 3,500# on each tire. That would still make the ENDURANCE tire just fine to use.
