My 2008 Starcraft 14RT OFF-ROAD POPUP came with HERCULES TERRA TRAC M/T tires LT235/75R15 M+S Load Range C...
I got around 40K out of these and then started wearing the inside of one side out big time. I tracked that down to losing the tire weights (out of balance) going down I59 in northern AZ..
I replaced them with BFG ALL TERRAIN M+S LT235/75R15 Load Range C..
My trailer weighs in around 4200lbs loaded down...
No problems so far with blowout or bad tire wear for past two years... I think my tire pressure is around 60lbs. I am a 55-60MPH guy when towing...

I would love to redo my shocks on this trailer they are mounted at about a 45 degree angle - you know that ain't good.... They look pretty small in diameters too. Never did look at them for model number...
