Before you go with bigger tires, load the truck up some. When its loaded down, have smeone turn the wheels left and right. Look at clearance while your turning. Thats the most common tire rub issue.
Forgot the exact model, but I have some firestone AT tires that came with my used 2019 ram. 55k miles on them so far. They are close to being replaced. I dont go too thin. But, by other folks standards, they're probably a 75k mile tire. Besides geetting a deer on havested fields, my only challenge is snow. They're great there too. I think they destination model lines.
If I were to buy a truck, I'd go for a tacoma. Although, I try to buy US cars. Probably buy another truck in 5 years if possible. NEw one close to retirement, or a decent towing SUV. Enclosed trailer, small camper, of 21ft boat.
