Having read the threads on a few sites for many years there are some common things that pop up. Certain names like Tow Max are most often mentioned. Then GY Put out the Marathon, a good tire for some time then they became known for problems. Other names like Carlise and Sailun have very few reported problems, same with Endurance but after the Marathon fiasco I'll never trust GY again.
The last couple years manufacturers are using tires with a 10% margin, not so on earlier years.
If your unit is close to GVWR the sticker temps are your best guide. If you are considering adjusting you need to scale each tire on each axel as not one will usually match another!
