The best all-terrain size for you is almost certainly the tire size your vehicle left the showroom with. And you thought sizes were complicated! SL tires can be inflated to 36 pounds per square inch psi , while XL tires can hold 42 psi.
One designed to hold less air can be made thinner and lighter. One designed to hold more will need to be thicker and heavier. In this verbiage, this denotes anything shy of a commercial vehicle. LT tires come standard on heavy-duty pickups, like the Ford Super Duty. An E-rated tire, for instance, can now hold as much air as ten old plies, using just three plies made from modern materials. All you need to understand is that B-load tires can hold the least air, and therefore support the least weight, and that progresses on up to F, which can hold the most air and therefore support the most weight.
On LTs, maximum pressures vary with tire size. And not only will more bumps reach the suspension, the momentum of that heavier tire will also be greater, so those bumps will effect the suspension more severely.
It also takes more energy to accelerate or decelerate a heavier tire. Use this calculator to determine the correct pressures for your LT tires. Bergeson says that Toyo uses different compound materials for the two categories of tires, as well as different tread designs.
So Toyo optimizes those tires for that use. And the tread pattern features smaller voids and more siping. Sipes are the squiggly little lines inside the tread blocks. The noise you hear all-terrain tires make is created by air passing through those voids. So making sipes smaller on tires biased to on-road use helps make those tires more civilized.
The one area where an LT tire might be more resistant to punctures than the lighter option will come simply from increased thickness of the tread on the former. That means the rubber that the LT tires drive on is that much thicker. Not only is the lower-silica-content compound more resistant to cuts, tears, and deformation caused by sharp rocks, but the larger voids are better at ejecting those rocks before they can cause damage.
Fewer sipes are also less prone to picking up and being damaged by very small stones. But those larger voids enhance traction on loose surfaces like mud. Notably, equipping LT tires with the ability to contain higher air pressures also gives them one feature that really helps off-road: because all that extra air requires a thicker, stronger bead, LT tires mount more securely to their wheel rims.
This lets drivers safely run lower pressures off-road. Tire inflation pressure and time Pssst your tires are leaking! Just another reason why it's so important to check your tire pressure.

In addition, all-weather tires are touring tires, meaning they are designed for on-the-road comfort and confidence rather than off-road traction. They strike a balance between the quiet comfort of touring tires and the confident handling and winter performance of three-peak mountain snowflake-certified tires.
Rather than being designed for off-road performance, these tires are made to please drivers who are tired of changing their tires from winter to summer and vice versa.
