I put Sailuns on this trailer before I ever picked it up but...I had the benefit of time and not in a bind like you were. For your circumstance you did the best you could. Having had a TK zap me with 7 k in damages on my last trailer (wasn't a year old) I have no use for them whatsoever. You were in a tight and IMO made a great decision going with the upgraded steel cased tire. Just keep an eye on them and be sure you have a TPMS.
