My previous trailer was a Trailex model 7541 tandem-axle lightweight open aluminum trailer, which carried my old Porsche 911. Loaded weight of the rig was ~ 4000#. After two catastrophic failures of the OE General tires on the trailer (each failure destroyed a fender), I replaced all tires with 205/75x14 Goodyear Marathon radials. Over the ensuing 4 years, ~15K miles, I've had NO problems with the Marathons: They've tracked and braked well and had no issues of any kind. Exemplary trailer tires! I HAVE been careful to maintain 50 psi pressure.

I just picked up a new Trailex model 80180 trailer, the enclosed variety, which weighs 2300# and will be hauling a 3200# Porsche 997 GT3. The loaded rig will weigh ~ 5500#, and the trailer came equipped with 205/75x14 Mission brand trailer-rated radials. Research on the web has turned up many reports of sudden failures of these tires, causing major damage to the trailers they were on.

I learned my lesson the hard way with the OE Generals that came apart: Nothing will spoil your trip like a trailer tire failure. So I think I'm going to swap The Missions for a set of 215/75 x 14 Marathons. The one-size upgrade will net me another ~ 400# of rated load capacity, giving me ~ 2000# of 'headroom', and, presumably, better durability.

That said, I have to admit that I'm not totally confident I'm doing the right thing. Someone elsewhere made a comment to the effect of, "Does anyone make a decent trailer tire these days?". It seems many have a sad story to tell about their trailer tires, no matter what brand/size. Not confidence-inspiring!

Best regards.
