I had to change to 16" wheels to use the LT tire size I wanted. Not sure if you can get a LT in 15". My 33' 5er came with Marathons and they were the worst of all the ST tires I tried. If you have to stick with ST tires, try Maxxis.

Some people have good luck with ST tires, but it is not if, but when they are going to fail. The added confidence with LT tires is worth the added cost of new wheels.

I had no failures with Yokohama LT 215/85-R16. They are rated at 2680@80 psi. Just check for clearance before you buy.

I won't tow a trailer with only one spare. If one blows on the way to your camping site, you worry the rest of the weekend if you can get home without a spare.

Maybe I haven't figured this out but how does one check cold tire pressure in the middle of a trip?

I check tire pressure before each trip and then monitor it via my TPMS through out the trip. The only time I have made a mid trip adjustment was last weekend. My duals were set at 98 per my tire gauge but my TPMS showed my outside left at 96 PSI while the other 3 showed 98. I attributed this to the +/- 2 PSI tolerance of the system. After 3 hours all 4 duals were up to around 104 PSI on both the TPMS and gauge except the left outer which was 100 TPMS and 102 on the gauge. I bumped that tire up to 104 on the gauge.

After that, all duals remained within +/- 2 PSI of each other on the TPMS for the remaining 7 hours of drive time for that trip. The next morning all PSI were back to 96 PSI on both TPMS and gauge.

I wonder why the tire companies publish instructions regarding tires and pressures when half the people out there ignore them an make up their own instructions?

My Heartland Big Horn has 6000 lp axles and I run Goodyear Marathon tires. Some have suggested changing to a LT tire. Does anyone know it that would that take new wheels? This tire thing has been a concern since we have had two blow outs in 2010 (and before the Goodyear, compressor, monitoring system and two spare rack)

Your trailer has 6k axle so I assume the wheels are 16". If thats the case the wheels will work fine.
Any of the recommended LT235/85-16 E or LT245/75-16 E tires at 3042 lbs will have the capacity for those 6k axles. Four of them will give you 12168 lbs of very reliable long term capacity.

The 16" Marathons are 30.7" in diameter.

The LT235/85-16 are around 31.7" in diameter.

The LT245/75-16 are around 30.4" in diameter.

Make sure the tire has proper top and side clearances. Dexter axle says 1" min between the tires.
