New Cedar Creek tires
We are about to pull the plug on a new 2016 Cedar Creek 36CKTS. Although we have loved our Chaparral, we wanted to upgrade a bit and get something with self leveling and a king size bed. My question...

What's the deal on using ST instead of LT tires?
-- Fed Gov forced the RV industry into using ST tires for weight ratings. Use to use GY G614 LT, but had to go w/ ST's. We've had no problems w/ the Westlake(?) tires we've been using past 3-4 years. If owners want to switch out to LT's they can, but we can't put LT's on at factory. ST tires have a higher weight rating than LT's.
This was the question I asked the CC rep at The Syracuse RV show and his reply. I looked at the side wall of the ST 235/80R16 "E" and it's rated for 3520 lbs @ 80 psi. Did a quick search on Cooper Tires web site at LT 235/85R16 and they came in at 3040 lbs at 80 psi. I forgot, but think all LT 16" are 3040 lbs. Our 5er is still in storage, but I think it's tires are LT245/85R16 and coach has a GVW of 13,800. Apparently no much how one argues, the factory won't put LT tires on. Not sure if dealer would make a deal with a customer on switching them upon purchase of RV.
BS. If a trailer has, 5,200 or 6k axles the manufacturer can install 16" LRE LT's. They just do not want to spend the money for higher quality tires.
ST tires are dirt cheap bought by the train car loads.
LT tires are all position tires, which includes trailer.
High end heavy trailers are coming with 215/75R17.5 all position tires.
In fact trailers can come with P tires providing when they are derated for trailer service.
The real problem is with 7k or derated 7k axles. There is not a 16" LRE LT to cover the required capacity. Chris
