    I'm thinking about buying 15 x 10 Rockcrawler wheels, which are sold by Four Wheel Parts Wholesalers. My question is, can they hold up 36 x 12.50 15 Super Swamper SX tires?? They are made by a company called Tech-1 and they rate them up to a 33 in. tire only. Anybody using these wheels?? Likes/dislikes??

    Those are made especially for trucks. I'm sure they are strong enough for 36's...if you don't go Dukes of Hazzard on them. I used to have generic old chromespokes and they held up to abuse and 35's just fine.
    The only other thing I want to warn you about is CHECK THE BACKSPACING. I believe those Rockcrawler rims have a 4 inch backspacing. 4 inch backspaced rims rub my tie rod ends when I turn a corner. And we should have the same (Dana 44) frontend in our trucks. Yours might be different, but just check before you order them. I made sure to buy my new rims with a 3.5-3.75 inch backspacing.
