Yes, but don't fold a box side in half. Oddly enough if you do that you may go oversize on the package. Check into it but I think the USPS size cut off is 84"

So 2 pieces of 25" x 25" x 2"cardboard gets L=25 G=54 for a box size of 79" Going to a 26" by 26" gets you L=26 G= 56 for a box size of 82"

Play around with the online calculators...for rims it looks like 26 X 26 X 3 is the max without hitting a balloon charge. I can ship 2 rims from Tampa 33617 to NY 13760 for $16. Jump up to a 27 x 27 x 2 and the price is $45
