I bought the Cougar with an option called the "Mountain Package" at the time. It came with a larger tire and some extra suspension. So while the specs say the tire size is ST225/75R15, it actually came with an ST235/80R16, LR E. The axles have not been de-rated, they are 5200 lbs per axle.
On our way to AZ this year, we had a severe tire blowout in New Mexico, and it did about $2,000 worth of damage to the rig. So now, I am trying to be smart and maybe be overly cautious. So I am going to the LT tires, and was just trying to make sure I am going to be OK with the extra pressure after travelling. I do have metal valve stems with the TST TPMS system.
Tuesday, (1-28-14) I am putting on LTXMS2 Michelin tires all around, ST235/85R16. The load rating is a bit less than the ST tires, but well within spec. The size is slightly taller, but I should be OK. The load rating is 3042 @ 80 psi, with 5200 lbs axles on the trailer. That gives me some breathing room. But I also weighed the rig, the trailer rear axles weighed 8,240 lbs, while the hitch weight was an additional 1,860 lbs.
I really want to thank you guys for all your help. Any other thoughts welcome.
