thanks, i just had a look and that really helped make a decision,
55 lbs for a 285, 75r18 all terrain type tire across the board unless you get a 117(2800lb) load rated set of at's, and that is basically a passanger car tire.
I like the specs of the st maxx myself, nice tread depth, no ridiculous lugs sidewall protection, decent all around truck tire.
I was thinking about the wrangler duratrac but they aren't that much lighter (1.7 lbs) and they have kinda weak sidewalls and are softer rubber. The st maxx have re-inforced layers, stand up taller, and have better sidewall protection.
