    They are 15x7. I have a set and the size is stamped on the inside of the rim.

    Why can't you go to 33's if you run the 33x10.5's?

    The ones I have on my truck were just slightly over 7 inches wide. Once they were beadlocked they measure about 7 5/8''. I run a 37 x 13 bogger with no problems. I wouldn't go any wider than that on such a narrow wheel.

    I used to have an '87 K5 with the factory alloy wheels. 33x12.50's fit them just fine. /forums/images/icons/cool.gif

    I used to air mine down to 20 psi up front and 18 in the back when playing in the rocks. That's enough to really soften up the ride, get a good grip on the rocks and not have to worry too much about popping a bead or crunching the wheel. /forums/images/icons/cool.gif

    Those are ralleys, not alloys. I have 8" ralleys too. The alloys are 7".

    I like the alloys. They're cool looking.
