i bought a used platium living quarters trailer it came from mfg with 235/85/16 10ply tires the gvwr is 15344 tires now arnt to bad but dont want any problems if i upgrade to 14 ply what is a good brand to buy and will my factory wheels handle the 110 psi and whats the difference in all steel andpoly steel need some input
I got a set of these G614RST's that are coming 7 years old, they look like new, but, they're 7 years old, time for them to go. Called the local GY dealer and got a quote of $405.00 each. That's tax, mounting, balancing, the whole works. $405.00 per tire, that's not good..... The G614 is rated at 3750# at 75 mph. The casing is regroovable as well as retreadable. If your trailer is stamped for 10 ply load range "E" tire, I would look closely at these 2 steel brands/models I've listed below. They are rated at 3042# at 99 mph or faster.....

how woukd i know if im ok to move up to the 14 ply with the factory wheels that came on it ?
Your rims will have a part number/model number. This number would indicate what the maximum weight and or the maximum air pressure is for the rim.... The maximum weight and or maximum air pressure may be stamped on the rim itself. Depends on the mfg. Quickest way is to check with a reputable commercial tire shop in your area, have them take a look before ordering your tires. A 14 ply can be run in place of the 10 ply on the 80 psi rated rim, just have to run it at 80 psi which gives you a 3042# rating, same as the lrE 10 ply tire. What is stamped on the serial number tag? What is your gross axle weight rating for each individual axle? 6-7-8000#? My trailer has 2-8000# axles, but has a GVWR of 18500#. Mfg. is figuring the truck is going to carry at least 3500# of pin weight. That leaves 15000# for the tandem axles. Remember, 4 of these 14 ply, 235/85-16 tires only give you at total rating of 15000# on the tandem axles even though the axles are rated at 8000#. 4 10 ply of the same size give you a total of 12168# total capacity for both axles. I'm rambling....

While you can run 14 ply tires at 80 psi on wheels that are only rated for 80 psi. It's probably not a good idea.
You mention your daughter will be hauling this trailer. The risk is too high that she or somebody helping her will look at the tire sidewall, see the 120psi rating and try to inflate to that limit. Over inflating the rim. The numbers on the tire sidewall are MUCH more visible than any stamp on the metal rim.
