Re: Running "trailer" tires at reduced pressures. I remember that when I was researching the difference between a truck tire and a trailer specific tire, I found that trailer tire sidewalls are made to withstand the sway/fish-tail action that some trailers (TM not-so-much) have as they ride down the road.
Possibly, Carlyse tires is recommending that their tires be kept inflated at the max is for that reason - that lesser inflation will result in more role on the tire during sways with increased strain on the sidewalls?
