Thanks everyone for your replies, I'm going to do some digging around based on the feedback. My trailer weighs around 8,400 which rules out many of the LT in 15". But i will look into maybe converting to 16" wheels and also check out Maxxis and couple other names thrown out. I don't put on a lot of miles and never drive over 65mph. Current tires are towmaster and carlise brand 4-5 years old. Having had 2 blowouts in the past i would rather replace than be sitting along the freeway somewhere in 100 degree temperature.
