The bigger you go on tires, the more serious weight becomes.

Smaller tires, it means less...but whatever you do to your new jeep, realize that everything ADDS weight. Very few mods make your truck lighter.

Every ounce drains your power. So yes, weight is the first thing i look at for tires. tread is second.

You will find, the manufacturers that make the lighter mud tires also make the best treads and spend the most research on development. BFG and Goodyear.
