ST vs LT Tires -- I'm confused

FYI, my FW has a GVW of 11,300 lbs, and has a fairly light pin wt. For D-range tires, I'm nearly at the limit of their capacity. I ended up going with E-range Carlisles this last time because I couldn't wait for Discount to ship in the Maxxis I really wanted. So now, tell me how many E-range 15" tires you can find, ST =or= LT? NONE in LT and very, very few in ST. FWIW, even Maxxis are simply up-rated D-range LT-type tires, IMO. With the prevalence of "light" or "1/2 ton" TTs and FWs these days, all running 15" wheels, you'd think even ONE tire company would grab the bull by the horns and make a =good= ST. We certainly know the bean counters who never leave their offices at the RV manufacturers won't demand it.

That is strange NADA must have their data all screwed up!

Here's my data:

2004 Komfort 25FSG
UVW - 6,679 lbs
dry pin - 1,113 lbs
dry ratio - 16.66%
GVW - 11,300 lbs per the sticker
calculated pin wt @ 16.66% and full GVW - 1,882 lbs"
11300-1882=9418 on the axles fully loaded. Might be kind of hard to add that much stuff to a 29'er to get it up to GVWR with 4621 CC.

So what is the actual scaled weight on your axles?

If you are running the Carlisle at 65 lbs inflation on your D rated wheels, then you have 2540 pounds capacity. The two LT's that I noted have 2450 capacity. I think I would take one of those over a ST any day.

So? My FW came with 80 psi-rated aluminum wheels, mounted with E-rated Carlisles, now. Given that the stickered D-rated tires are already cheap tires uprated, why take a chance? I went with E-rated tires as soon as the first set went belly up. Given my weights, I could easily run E-rated LT's if I wanted to blow a bunch of cash on 16" rims, and =still= be under sidewall ratings for the by-the-bookers.
