Depends how much weight you’re putting on the tires.
Considering you aren’t taking advantage of the greater treadwear capability of a E tire it doesn’t make sense for miles.
If you’re hauling a popup camper and some camping gear in the back you have no real use for a LT tire (presume your burb is a 1/2 ton one). If you have significant weight on the rear axle, the LT will handle it better because it’s rated for higher psi/greater load.
However saying a LT tire rides tougher than a P is largely false. Largely meaning how compliant a tire is is largely related to the pressure in the tire.
If you run the proper pressure for the weight, a LT will be largely as comfortable as a P tire.
And then there’s XL tires if you’re looking for a tweener rating.
