Tires just one more time

We will need more info than that as ST235/80-16 tires comes in E and G load ranges for a good recommendation. E = 3400/3500 lb range and G over 4000 lbs

Does your trailer have 5.2k axles.....6k axles....7k axles ?

What is the trailers GVWR ??

And just to add to the mix here. We had TowMaxx installed in 2014. Have them inspected every year and they're still good.

I installed Maxxis 2 years ago and like them but my next set will be Sailun S637T with a load index of 132 which is 4400# capacity, if your rims can handle 110 psi. I’m on a few RV Forums and have read nothing but good reviews. I looked at one at a tire dealer and they are heavy. They’re also reasonably priced. More info:

Michelin XPS RIBS - if you can afford them. I got 9 years out of mine on my Cedar Creek 32WRL Silverback, which weighed from 12-12.5K lbs.

Unfortunately, my new 5ver has "G" rated tires, and XPS RIBS only come "E" rated.
