New Cedar Creek tires

I recently attended a RV show and looked at some Westlake tires on a couple of Forest River fivers with 7000# GAWR axles. I also took pictures. Here are a few pictures of the LRG steel cased tires.

So much BS about ST tires.

Is the Westlake LRG a steel ply carcass tire? If not, then get GY G614's or Sailun S367's.

To the guy that said 17", no one uses 17" tires on trailers.

17.5" yes!

Chris

I looked at the LRG on a CC 34RL and they are all steel ply. Tread looks like the Sailun. Chris

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

For one thing on your 2006 Cedar creek your rims are only rated for 80 P.S.I. most newer big 5er's about 2011 or so on rims are rated for 110 P.S.I tires,on my 2015 Montana 5er I have Geostar G574 14 ply G rated LT tires 235/85r16 rated at 3750 lbs per tire and a speed rating of 80MPH(not that I would ever go that fast) but stock they came with E rated ST Trailer Kings rated at 3400lbs that are just not the right tool for the job on a heavy 5er, Montana and others brands have a option for Goodyear G rated LT G614's but on my 2012 trade in I already had Geostar G574's and had them put them on the new 2015 and the difference is amazing the G rated LT's I bought do not Sag like the lame stock E rated ST's and after 10K miles on them on all kinds of rotten roads around the US not one problem do yourself a favor and get rims that will handle 110PSI Tires and get G rated LT Goodyear G614's or Saliun's or like my Geostar G574's and RELAX!!!!!

In my opinion the country of manufacture has little to do with tire problems.

Most tire problems are caused by age, improper inflation and (more often than not) improper application.

RV manufacturers are quite often installing tires that are simply not up to the task as far as weight ratings go.

Totally disagree! I posted a couple of months ago on my experience with China tires!~ One year old, less than 5K miles and one blew out producing $3K worth of damage to my rig! Do not be fooled, replace those cheap tires with something good, That will be a minor expense, compared to all the other things a bad tire can do! BTW I replaced my tires with the Goodyear G614.

ST tires in general are built to meet lesser standards than plain old passenger tires. In the end they maybe OK for general use on utility and boat trailers.
However they are too often problematic when used on lager heavier RV trailers.

Are you referring to tires that were designed for casual local service that are being installed on most new large trailers that spend extended hours at freeway speeds with poor results?

These tires get inflated weight ratings based on speed restrictions, and often fail within a year or two of service. Chris

I am referring to RV manufacturers attempting to cut corners by installing marginally rated components.

So... Yeah.

The thing is that the end user needs to check for themselves and make educated decisions on what to do about the equipment.
