An example of the difference can be found by looking up the service description load rating for a popular LT235/85R16E tire (3086#) and compare it to the load range letter on the tire (3042#).
How and the heck is a normal Joe expected to buy tires that are safe and meets his requirements?

I ordered a Rockwood 2703 in April 2015 and took delivery in June 2015 and it came with Constancy 205/75/14 ST tires that were "L" rated my GVWR is 7700 lbs. I can't remember what the build date of tires were. I looked a few weeks ago so I will have to check again.

A question........the G614 is touted as the 'best' alternative to the original tires on 5er's, because they are LT and have higher weight rating, but also have higher speed rating.

Yet, several online sources I find show the G614 to be rated at 62mph. That's LESS than an ST tire.

Which is correct? I find a lot of info online, most contradictory or confusing. Is there a link to show the true speed rating of these?

Also, the G114's appear to have a high speed rating, but are on larger rims. Don't know how to find out if they are simply "Replace as is" or "Plug and Play" with the bigger rim, or not........ How does one figure that out before buying?

Thanks.

You need to do a comprehensive search for RV tires and you will need to know what your trailer weights are along with the placard weights listed on the trailer. You will than need to insure any tire purchase meets or exceeds these requirements. You just cannot go out and buy a Goodyear, Michelin or any other brand of tire just because other people recommend them. They must meet the needs of the trailer and support the axle loads properly.
Such as this chart by Michelin:http://www.rvtirepressure.com/assets..._Inflation.pdf
Also per the Goodyear web site the ST235/80R16 tire will not support my trailer or load. These are rated at 3,000 at 65PSI. I believe that is why they where dropped by Cedar Creek on their trailers.

Such as a in my case; the axles weights are 7,000 LBS each and the tire size is ST235/85R/16G. So you go to the tire manufacture web site and look up the tire load and inflation chart for that tire. In my case; the tire will support a load of 4,080 LBS @ 110 PSI cold in single wheel application. Any tire I purchase must meet or exceed these requirements.

I picked up my new Mini Lite 2503S on June 6, 2015; same ST205/75R14 tires as yours. Two of them are 4414 and 2 are 4514 (i.e., 44th and 45th weeks of 2014, or end of Oct/beginning of Nov, 2014).

Are you looking at the LT235/85R16 tires by Goodyear? if so per their load inflation table (chart) these are only good for a load of 3750 LBS @ 110 PSI in a single wheel application at this site: The Inflation Loading - Goodyear RV
So they will not support your Cedar Creek trailer adequately.

A comprehensive search is leading me to conflicting information. That's the problem.

I can find the trailer weight. I can figure the requirements for each of 4 tires for it for weight.

What I can not find.........is the answer to some simple questions.
1) What is the speed rating of a properly inflated G614 on 16" rims, and a G114 on 17.5" rims? I find 62, 65, and 75 for the answers to speed rating for these tires on different tire sites online. Why the variance and confusion?

2) Will a G114 tire and 17.5" rim assembly fit on my trailer by simply replacing 1 for 1? If not, what do I have to do to get them installed, specifically?

I am not a gearhead. I'm an old telecom guy. I worked inside. I just need some reliable information from somewhere. Others have done this and say it's simple, and maybe it is, but I'm missing some needed initial information, somehow.

Thanks.

EDIT: Sorry, posting while you were trying to help and answer.

OK, so G614's won't work. Then why are so many folks replacing their original tires with them? And more importantly, what WILL work as a good replacement?

The G614's say "Load Range G".

The original equipment tires on my trailer will be Load Range G.

So, why wouldn't G614's work??????????

See why I'm confused???
