Considering changing steer tire size on a heavy haul

I could use the help I have a 20k front end been running 315 80r22.5 steers debating going to a 385 steer tire or a 11r24.5 steer tire. Reason being 315s are not lasting me long at all especially for the price tag and are wearing excessively on the inner and outer sides of the tire, I've tried PSI, alignments, rotations, have had my front end checked and nothing works. If you have some insight it would be appreciated.

 

I don't know for sure, no scales around and what I haul can vary pretty greatly. But on a total weight i can weigh anywhere from 118k-130k if you go off math. Id have to go through the numbers and figure what exactly what my truck tank holds. The truck is a truck and pup

 

Yeah I've talked to my mechanic about what it takes to switch, either way i have to buy new wheels. I've even considered the possibility that the worn oilfield roads are just coned and maybe it's just wearing my tires that way lol. My truck is a truck and pup and the truck also has 2 tag axles. But I only run them on pavement. I just want to use a tire that wears more evenly so that I can get more life out of my tires. I just do not know if going to 385s or switching to 11r 24.5s would be better.

 

For sure I appreciate the input we have 3 other trucks same setup as mine. if I can't find a way to weigh it I will ask around see if these guys have gotten a weight

 

Yes I've tried both thats why I am resorting to trying 385s and my truck actually weights over 130,000 fully loaded I found out.
