What tires would you want to put on a 20 foot gooseneck that is going to have a 1000 gallon tank on it. I have 7.00 - 17 inch primex HE 100xt on them. But I'm thinking that these tires aren't going to be good enough. This tire will see highway 95% of the time.

But I'm not sure if I need a D or E rated tire.

Any help would be great.

 

At least E tires, I would never use D rated tires.

 

e or g rated would be the best option if available

 

E or a G rating tire, okay, is there a name brand you would recommend?

 

g or h rated

what is the rating it has now on the trailer and on the tire?

 

What are your axles rated for? That will tell you where you should be for a tire.... Had a Dump trailer that I ran some Denman's on which we consistently overloaded and had good luck with them. But I think the Denman's where only 15 inch rim, you should be at least a 16 inch rim.
